Kev ua tiav thiab ua tau zoo ntawm cov raj lossis cov yeeb nkab yog qhov teeb meem ntawm optimizing 10,000 qhov chaw, nrog rau cov khoom siv tu.Nrog rau ntau qhov chaw txav hauv txhua hom zeb thiab txhua daim ntawm cov khoom siv peripheral, ua raws li cov chaw tsim khoom tau pom zoo los tiv thaiv lub sijhawm saib xyuas yog qhov nyuaj.Yees duab: T&H Lemont Inc.
Editor daim ntawv.Qhov no yog thawj feem ntawm ob-ntu series ntawm optimizing tubing kev ua tau zoo.Nyeem qhov thib ob.
Kev tsim cov khoom siv tubular yog ib txoj haujlwm nyuaj txawm tias nyob rau hauv cov xwm txheej zoo tshaj plaws.Factories yog qhov nyuaj, xav tau kev saib xyuas tsis tu ncua thiab, nyob ntawm seb lawv tsim dab tsi, kev sib tw yog qhov hnyav.Ntau lub tuam txhab hlau yeeb nkab tau nyob rau hauv lub siab hnyav los ua kom lub sijhawm ua haujlwm kom tau txais txiaj ntsig zoo tshaj plaws thaum tawm hauv lub sijhawm me me rau kev saib xyuas.
Cov xwm txheej hauv kev lag luam niaj hnub no tsis yog qhov zoo tshaj plaws.Cov nqi ntawm cov khoom siv tsis txaus ntseeg siab, thiab cov khoom xa tuaj ib nrab tsis yog qhov txawv.Tam sim no ntau dua puas tau, cov yeeb nkab manufacturers yuav tsum tau ua kom lub sijhawm ua haujlwm siab tshaj plaws thiab txo cov khoom seem, thiab tau txais cov khoom xa tuaj ib nrab txhais tau tias lub sijhawm tsim khoom luv dua.Kev ua haujlwm luv luv txhais tau tias muaj kev hloov pauv ntau zaus, uas tsis yog siv sijhawm los yog ua haujlwm tau zoo.
"Lub sijhawm yog qhov tseem ceeb ntawm hnub no," hais tias Mark Prasek, North American Tubing thiab Tubing Muag Tus Thawj Coj rau EFD Induction.
Kev sib tham nrog cov kws tshaj lij hauv kev lag luam txog cov lus qhia thiab cov tswv yim kom tau txais txiaj ntsig zoo tshaj plaws ntawm koj qhov kev lag luam qhia qee cov ntsiab lus rov tshwm sim:
Kev khiav ib tsob nroj ntawm qhov ua tau zoo tshaj plaws txhais tau hais tias kev ua kom zoo dua ntau yam, feem ntau cuam tshuam nrog ib leeg, yog li kev ua kom zoo ntawm cov nroj tsuag tsis yog ib txwm yooj yim.Ib qho chaw nto moo los ntawm yav dhau los The Tube & Pipe Journal tus sau xov xwm Bud Graham muab qee qhov kev pom: "Ib yeeb nkab zeb yog lub cuab yeej khib."Paub tias txhua lub cuab yeej ua li cas, nws ua haujlwm li cas, thiab txhua lub cuab yeej cuam tshuam nrog lwm tus li cas yog li ib feem peb ntawm txoj kev ua tiav.Ua kom txhua yam txhawb nqa thiab ua kom zoo yog lwm qhov thib peb.Qhov thib peb zaum kawg yog mob siab rau cov neeg ua haujlwm kev cob qhia, cov tswv yim daws teeb meem thiab cov txheej txheem kev khiav hauj lwm tshwj xeeb rau txhua tus kav dej lossis cov kav dej.
Tus naj npawb ib qhov kev txiav txim siab rau kev ua haujlwm zoo ntawm cov nroj tsuag tsis muaj dab tsi ua rau cov nroj tsuag.Cov khoom siv raw no, tau txais ntau tshaj plaws ntawm cov dov zeb, txhais tau hais tias tau txais ntau tshaj plaws ntawm txhua lub coil pub rau lub tshuab dov.Nws pib nrog kev txiav txim siab yuav khoom.
coil ntev.Nelson Abbey, tus thawj coj ntawm Abbey Products ntawm Fives Bronx Inc. hais tias "Cov yeeb nkab mills vam meej thaum coils ntev li ntev tau," hais tias Nelson Abbey, tus thawj coj ntawm Abbey Products ntawm Fives Bronx Inc.Txhua qhov kawg ntawm lub yob yuav tsum muaj lub pob tw weld, thiab txhua lub pob tw weld tsim ib seem.
Qhov nyuaj ntawm no yog tias cov coils ntev tshaj plaws yuav muag tau ntau dua, thaum cov coils luv luv yuav muaj nyob ntawm tus nqi zoo dua.Tus neeg muag khoom yuav xav txuag qee cov nyiaj, tab sis qhov ntawd tsis yog qhov kev xav ntawm cov neeg hauv kev tsim khoom.Yuav luag txhua tus neeg uas khiav ib tsob nroj yuav pom zoo tias tus nqi sib txawv yuav tsum loj los them rau qhov poob ntawm kev tsim khoom cuam tshuam nrog kev kaw cov nroj tsuag ntxiv.
Lwm qhov kev txiav txim siab, Abby hais tias, yog lub peev xwm ntawm lub decoiler thiab lwm yam kev txwv ntawm lub zeb nkag.Tej zaum nws yuav tsim nyog los nqis peev rau hauv cov khoom siv muaj zog ntau dua los tuav cov yob loj, hnyav dua los ua kom zoo dua ntawm kev yuav cov yob loj.
Kev txiav kuj yog ib qho tseem ceeb, txawm tias txiav yog ua hauv tsev lossis sab nraud.Slitter rewinders muaj qhov hnyav tshaj plaws thiab txoj kab uas hla uas lawv tuaj yeem ua tau, yog li qhov kev sib tw zoo ntawm yob thiab slitter rewinder yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig zoo.
Yog li, nws yog kev sib cuam tshuam ntawm plaub yam: qhov loj thiab qhov hnyav ntawm cov yob, qhov yuav tsum tau muaj qhov dav ntawm lub slitter, kev tsim khoom ntawm slitter thiab lub zog ntawm cov khoom siv nkag.
Roll dav thiab mob.Nws mus yam tsis tau hais hauv khw tias cov yob yuav tsum yog qhov dav dav thiab qhov loj me los tsim cov khoom, tab sis kev ua yuam kev tshwm sim.Rolling mill tswv feem ntau tuaj yeem them nyiaj rau me ntsis hauv qab lossis dhau strip widths, tab sis qhov no tsuas yog qhov teeb meem ntawm kev kawm.Ua tib zoo mloog rau qhov dav ntawm qhov slit complex yog qhov tseem ceeb.
Qhov ntug ntawm cov hlau sawb kuj yog qhov teeb meem tseem ceeb tshaj plaws.Raws li Michael Strand, tus thawj tswj hwm ntawm T&H Lemont, kev ua haujlwm zoo ib yam tsis muaj burrs lossis lwm yam tsis sib xws yog qhov tseem ceeb rau kev tswj xyuas qhov sib xws ntawm qhov ntev ntawm cov sawb.Initial winding, longitudinal unwinding thiab rewinding kuj ua haujlwm.Coils uas tsis muaj kev saib xyuas tuaj yeem ua rau arc, uas yog qhov teeb meem.Cov txheej txheem tsim, tsim los ntawm dov tuag engineers, pib nrog lub tiaj tiaj, tsis yog nkhaus.
ntsuas ntsuas.Stan Green, tus thawj coj ntawm SST Forming Roll Inc., hais tias "zoo pwm tsim kom muaj txiaj ntsig zoo," said Stan Green, tus thawj coj ntawm SST Forming Roll Inc., sau tseg tias tsis muaj ib lub raj tsim cov tswv yim, thiab yog li tsis muaj ib lub tswv yim tsim pwm.Cov cuab yeej siv rau cov menyuam sib txawv thiab cov yeeb nkab ua cov txheej txheem sib txawv, yog li lawv cov khoom kuj sib txawv.Cov tawm los kuj txawv.
"Lub vojvoog ntawm cov menyuam nto yog hloov pauv tas li, yog li qhov kev sib hloov ceev ntawm lub cuab yeej hloov pauv tag nrho saum npoo ntawm lub cuab yeej," nws hais.Tau kawg, cov yeeb nkab hla lub zeb ntawm ib qho ceev xwb.Yog li ntawd, kev tsim qauv tuaj yeem cuam tshuam rau kev tawm los.Nws hais ntxiv tias cov qauv tsim tsis zoo siv cov khoom siv pov tseg thaum lub cuab yeej tshiab thiab tsuas yog hnyav dua thaum lub cuab yeej hnav.
Rau cov tuam txhab uas tsis muaj kev cob qhia thiab kev saib xyuas, tsim ib lub tswv yim los txhim kho cov nroj tsuag kev ua tau zoo pib nrog cov hauv paus.
"Txawm hais tias hom nroj tsuag thiab nws tsim tawm, txhua tsob nroj muaj ob yam sib xws - cov neeg ua haujlwm thiab cov txheej txheem ua haujlwm," Abbey tau hais.Kev khiav haujlwm ntawm qhov chaw nrog qhov ua tau zoo tshaj plaws yog nyob ntawm kev cob qhia tus qauv thiab ua raws li cov txheej txheem sau ntawv, nws hais.Kev tsis sib haum xeeb hauv kev cob qhia ua rau muaj qhov sib txawv hauv kev teeb tsa thiab kev daws teeb meem.
Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws ntawm cov nroj tsuag, txhua tus neeg ua haujlwm yuav tsum siv cov txheej txheem kev teeb tsa thiab kev daws teeb meem, tus neeg teb xov tooj mus rau tus neeg teb xov tooj thiab hloov mus ua haujlwm.Txhua qhov kev sib txawv ntawm cov txheej txheem feem ntau cuam tshuam nrog kev nkag siab yuam kev, tus cwj pwm tsis zoo, kev ua kom yooj yim, thiab kev daws teeb meem.Qhov no ib txwm ua rau muaj teeb meem hauv kev tswj hwm kev lag luam.Cov teeb meem no tuaj yeem tshwm sim hauv tsev lossis tshwm sim thaum tus neeg ua haujlwm cob qhia raug ntiav los ntawm tus neeg sib tw tab sis qhov chaw tsis cuam tshuam.Kev sib raug zoo yog qhov tseem ceeb, suav nrog cov neeg ua haujlwm uas coj kev paub.
Strand tau hais tias "Nws yuav siv sijhawm ntau xyoo los tsim tus neeg ua haujlwm kav yeeb nkab, thiab koj yeej tsis tuaj yeem tso siab rau ib qho kev pabcuam, ib qho loj-haum-tag nrho," Strand hais."Txhua lub tuam txhab xav tau ib qho kev cob qhia uas haum rau nws cov nroj tsuag thiab kev ua haujlwm."
Dan Ventura, tus thawj tswj hwm ntawm Ventura & Associates tau hais tias "Peb tus yuam sij rau kev ua haujlwm tau zoo yog kev tu lub tshuab, kev siv cov khoom siv tu thiab ntsuas kev ntsuas,""Lub tshuab no muaj ntau qhov txav mus los - txawm tias nws yog lub zeb nws tus kheej lossis cov khoom siv sab hauv ntawm qhov nkag los yog qhov hluav taws xob, lub rooj seev cev lossis lwm yam - kev saib xyuas tsis tu ncua yog qhov tseem ceeb kom nws nyob rau saum toj."
Strand pom zoo."Nws txhua yam pib nrog kev tiv thaiv kev tiv thaiv," nws hais."Qhov no muab txoj hauv kev zoo tshaj plaws rau kev ua haujlwm tau txiaj ntsig ntawm cov nroj tsuag.Yog tias cov chaw tsim khoom siv yeeb nkab tsuas yog teb rau cov xwm txheej kub ntxhov, nws tsis muaj kev tswj hwm.Nws nyob ntawm kev kub ntxhov tom ntej. "
"Txhua yam khoom siv hauv cov nroj tsuag yuav tsum tau hloov kho," Ventura tau hais."Yog tsis li ntawd cov factories yuav tua ib leeg."
"Nyob rau hauv ntau zaus, thaum yob tshaj lawv lub neej muaj txiaj ntsig, lawv ua kom tawv thiab thaum kawg tawg," Ventura tau hais.
Ventura tau hais tias "Yog tias qhov cua tsis tau khaws cia zoo nrog kev saib xyuas tsis tu ncua, hnub yuav los thaum lawv yuav xav tau kev saib xyuas xwm txheej ceev," Ventura tau hais.Yog tias cov cuab yeej tsis saib xyuas, nws hais tias, ob mus rau peb zaug ntau cov khoom yuav tsum tau muab tshem tawm los kho lawv dua li lwm yam.Nws kuj siv sijhawm ntev dua thiab raug nqi ntau dua.
Strand tau sau tseg tias kev nqis peev hauv cov cuab yeej thaub qab tuaj yeem pab tiv thaiv kev kub ntxhov.Yog tias lub cuab yeej nquag siv rau kev ua haujlwm ntev, cov khoom seem yuav xav tau ntau dua li cov cuab yeej uas tsis tshua siv rau kev khiav luv.Lub peev xwm ntawm cov cuab yeej tseem cuam tshuam rau qib kev cia siab.Cov tav tuaj yeem tawg los ntawm cov cuab yeej ribbed thiab cov welding chais muab rau hauv lub tshav kub ntawm lub vuam chamber, teeb meem uas tsis thab tsim thiab calibrating cov chais.
"Kev saib xyuas tsis tu ncua yog qhov zoo rau cov khoom siv, thiab kev sib raug zoo yog qhov zoo rau cov khoom nws ua," nws hais.Yog tias tsis quav ntsej, cov neeg ua haujlwm hauv lub Hoobkas yuav siv sijhawm ntau thiab ntau dua los mus ntes.Lub sijhawm uas tuaj yeem siv los tsim cov khoom lag luam zoo uas xav tau ntawm kev ua lag luam.Ob yam no tseem ceeb heev, tab sis feem ntau tsis saib xyuas lossis tsis saib xyuas, uas Ventura ntseeg tias lawv muab lub sijhawm zoo tshaj plaws kom tau txais txiaj ntsig zoo tshaj plaws ntawm cov nroj tsuag, ua kom muaj txiaj ntsig zoo tshaj plaws, thiab txo cov khoom pov tseg.
Ventura sib npaug kev saib xyuas ntawm cov mills thiab consumables nrog kev saib xyuas ntawm lub tsheb.Tsis muaj leej twg yuav tsav tsheb ntau txhiab mais ntawm kev hloov roj thiab tshuab lub log tsheb.Qhov no yuav ua rau raug nqi kho lossis raug xwm txheej, thiab rau cov nroj tsuag tsis zoo.
Kev tshuaj xyuas ib ntus ntawm cov cuab yeej tom qab txhua qhov tso tawm kuj tseem tsim nyog, nws hais.Cov cuab yeej tshuaj xyuas tuaj yeem nthuav tawm cov teeb meem xws li microcracks.Kev txheeb xyuas qhov kev puas tsuaj tam sim ntawd tom qab lub cuab yeej raug tshem tawm ntawm lub tshuab, es tsis yog ua ntej nws raug teeb tsa rau qhov dhau mus, tso cai rau ntau lub sijhawm los tsim cov cuab yeej hloov.
"Qee lub tuam txhab tau ua haujlwm ib txwm ua thaum lub sijhawm kaw," Greene tau hais.Nws paub tias nws yuav nyuaj rau ua kom tau raws li lub sijhawm teem tseg thaum lub sijhawm ntawd, tab sis tau sau tseg tias nws yog qhov txaus ntshai heev.Shipping thiab trucking tuam txhab uas muag yog overloaded los yog understaffed, los yog ob qho tib si, yog li kev xa khoom tsis ua raws sijhawm hnub no.
"Yog tias ib yam dab tsi tawg ntawm lub Hoobkas thiab koj yuav tsum tau xaj khoom hloov, koj yuav ua li cas kom tau txais nws?"– nws nug.Tau kawg, kev xa tawm huab cua yog ib txwm ua tau, tab sis qhov no yuav ua rau tus nqi xa tuaj.
Kev saib xyuas ntawm mills thiab yob tsis yog tsuas yog ua raws li kev npaj kho, tab sis kuj tseem hais txog kev ua kom zoo ntawm cov phiaj xwm kev saib xyuas nrog cov phiaj xwm tsim khoom.
Kev dav thiab qhov tob ntawm kev paub yog qhov tseem ceeb hauv peb qhov chaw - kev ua haujlwm, kev daws teeb meem thiab kev saib xyuas.Warren Whitman, tus lwm thawj coj ntawm T&H Lemont's Die thiab Die ua lag luam chav tsev, hais tias cov tuam txhab uas muag tsuas yog ib lossis ob lub yeeb nkab rau lawv tus kheej siv feem ntau muaj tsawg tus neeg los tswj lub zeb thiab tuag.Txawm hais tias cov neeg ua haujlwm saib xyuas muaj kev txawj ntse, cov chaw haujlwm me me muaj cov kev paub me me piv rau cov chaw saib xyuas loj dua, muab cov neeg ua haujlwm me rau qhov tsis zoo.Yog tias lub tuam txhab tsis muaj lub tuam tsev engineering, lub chaw pabcuam yuav tsum daws teeb meem thiab kho nws tus kheej.
Raws li Strand, kev cob qhia kev ua haujlwm thiab kev saib xyuas cov neeg ua haujlwm tam sim no tseem ceeb dua qub.Lub nthwv dej ntawm cov nyiaj laus uas cuam tshuam nrog cov laus cov menyuam yaus boomers txhais tau hais tias ntau ntawm cov kev paub ntawm pab pawg neeg uas ib zaug tau pab cov tuam txhab taug kev lawv qhov nce thiab nqis tau poob qis.Txawm hais tias muaj ntau cov yeeb nkab manufacturers tseem tuaj yeem tso siab rau cov lus qhia thiab kev taw qhia ntawm cov khoom siv, txawm tias qhov kev paub no tsis zoo li nws tau siv los ua thiab poob qis.
Cov txheej txheem vuam yog ib qho tseem ceeb ib yam li lwm cov txheej txheem uas tshwm sim hauv kev tsim cov yeeb nkab lossis cov yeeb nkab, thiab lub luag haujlwm ntawm lub tshuab vuam tsis tuaj yeem kwv yees.
Induction vuam.Prasek tau hais tias "Hnub no, kwv yees li ob feem peb ntawm peb cov xaj yog rau kev rov ua dua tshiab," Prasek tau hais."Lawv feem ntau hloov cov qub, muaj teeb meem welders.Tam sim no, hla dhau yog tus tsav tsheb loj. "
Raws li nws, ntau tus neeg poob qab yim lub pob vim tias cov nqaij nyoos tuaj lig."Feem ntau, thaum cov khoom siv thaum kawg tuaj txog, tus welder tawm," nws hais.Ib qho kev xav tsis thoob ntawm cov yeeb nkab thiab cov yeeb nkab manufacturers txawm siv cov tshuab raws li lub tshuab nqus tsev vacuum, uas txhais tau tias lawv siv cov tshuab uas muaj hnub nyoog 30 xyoo.Kev paub txog kev saib xyuas ntawm cov tshuab zoo li no tsis zoo, thiab nws nyuaj rau nrhiav cov raj hloov lawv tus kheej.
Qhov teeb meem rau tubing thiab tubing manufacturers uas tseem siv lawv yog lawv hnub nyoog li cas.Lawv tsis poob kev puas tsuaj, tab sis degrade maj mam.Ib qho kev daws teeb meem yog siv cov vuam vuam tsawg dua thiab txo qhov ceev ntawm cov dov zeb kom them, uas tuaj yeem yooj yim zam cov nqi peev ntawm kev nqis peev hauv cov cuab yeej tshiab.Qhov no tsim lub illusion tias txhua yam nyob rau hauv kev txiav txim.
Raws li Prasek, kev nqis peev hauv lub zog tshiab rau induction vuam tuaj yeem txo qis kev siv hluav taws xob ntawm qhov chaw.Qee lub xeev, tshwj xeeb tshaj yog cov neeg uas muaj neeg coob thiab cov kab sib chaws tsis sib haum, muab cov luv nqi zoo tom qab yuav khoom siv hluav taws xob.Nws hais ntxiv tias qhov kev txhawb siab thib ob rau kev nqis peev hauv cov khoom tshiab yog lub peev xwm ntawm kev tsim khoom tshiab.
Prasek tau hais tias "Feem ntau, tus welder tshiab muaj txiaj ntsig zoo dua li qub thiab tuaj yeem txuag tau ntau txhiab daus las los ntawm kev xa cov hluav taws xob vuam ntau dua yam tsis muaj kev hloov kho fais fab," Prasek tau hais.
Kev sib raug zoo ntawm inductor thiab resistor kuj tseem ceeb heev.John Holderman, tus thawj tswj hwm ntawm EHE Consumables, hais tias qhov loj me thiab nruab telecoil muaj qhov zoo tshaj plaws nyob rau hauv kev sib raug zoo nrog lub vuam log thiab yuav tsum tau tshem tawm kom zoo thiab tas li nyob ib ncig ntawm cov yeeb nkab.Yog tias teeb tsa tsis raug, lub kauj yuav ua tsis tiav ntxov.
Lub blocker lub luag haujlwm yog qhov yooj yim - nws thaiv qhov ntws ntawm hluav taws xob, coj nws mus rau ntawm ntug ntawm lub sawb - thiab zoo li txhua yam hauv lub tshuab dov, qhov chaw yog qhov tseem ceeb, nws hais.Qhov chaw raug yog qhov saum toj kawg nkaus ntawm qhov vuam, tab sis qhov no tsis yog qhov kev xav xwb.Kev txhim kho yog qhov tseem ceeb.Yog tias nws txuas nrog lub mandrel uas tsis muaj zog txaus, txoj haujlwm ntawm lub bollard yuav hloov thiab nws yuav rub tus ID raws li hauv qab ntawm cov yeeb nkab.
Ua kom zoo dua ntawm cov qauv hauv kev siv cov khoom siv vuam, cov ntsiab lus sib cais coil tuaj yeem muaj kev cuam tshuam loj rau cov nroj tsuag uptime.
Holderman tau hais tias "Cov kab kab loj loj tau siv kev sib cais serpentine rau lub sijhawm ntev," Holderman hais.Nws tau hais tias "Hloov lub induction induction kauj yuav tsum tau txiav cov yeeb nkab, hloov lub kauj, thiab rov txiav nws ntawm lub tshuab milling," nws hais.Qhov ob-thooj sib cais coil tsim txuag txhua lub sijhawm thiab kev siv zog.
Nws tau hais tias "Lawv tau siv rau hauv cov dov loj loj tawm ntawm qhov tsim nyog, tab sis txhawm rau siv lub hauv paus ntsiab lus no rau cov coils me me yuav tsum muaj qee qhov zoo nkauj engineering," nws hais.Cov neeg tsim khoom tsuas yog tsis muaj dab tsi ua haujlwm nrog."Lub me me, ob-thooj reel muaj cov khoom siv tshwj xeeb thiab lub ntsej muag ntse," nws hais.
Hais txog cov txheej txheem cua txias impedance, cov yeeb nkab thiab cov yeeb nkab manufacturers muaj ob txoj kev xaiv tseem ceeb: lub hauv paus cua txias rau cov nroj tsuag, los yog ib qho kev sib cais ntawm cov dej siab, uas tuaj yeem raug nqi.
Holderman tau hais tias "Nws yog qhov zoo tshaj plaws kom txias cov resistor nrog cov coolant huv si," Holderman hais.Txog qhov kawg no, kev nqis peev me me hauv qhov tshwj xeeb rolling zeb coolant impedance pom system tuaj yeem ua rau lub neej ntawm impedance.
Coolant feem ntau yog siv rau impeders, tab sis coolant tuaj yeem khaws cov hlau zoo.Txawm hais tias txhua qhov kev sim ua cov khoom me me hauv lub nruab nrab hauv lub cev lossis siv cov khoom sib nqus hauv nruab nrab los cuab lawv, ib txhia ntawm lawv tau txais los ntawm kev thaiv.Qhov no tsis yog qhov chaw rau cov hmoov hlau.
Haldeman tau hais tias "Lawv ua kom sov hauv qhov chaw induction thiab hlawv los ntawm lub cev resistor thiab ferrite, ua rau tsis ua haujlwm ntxov ntxov tom qab kaw los hloov lub resistor," Haldeman tau hais."Lawv kuj tsim nyob rau hauv telecoil thiab thaum kawg ua rau arc puas tsuaj."
