Cov txheej txheem ntawm cov kav dej kub-kuav los tiag seamless steel kav muaj xws li billet npaj ua ntej dov, yeeb nkab billet cua sov, tho, dov, sizing thiab txo, steel yeeb nkab txias, steel yeeb nkab txiav taub hau thiab tus Tsov tus tw, segmentation, straightening, flaw detection, phau ntawv tshuaj xyuas, tshuaj tsuag kos cim thiab luam ntawv, Bundle ntim thiab lwm yam txheej txheem yooj yim.Niaj hnub no, feem ntau muaj peb lub ntsiab deformation txheej txheem nyob rau hauv zus tau tej cov kub dov seamless steel kav: tho, yeeb nkab dov, thiab sizing thiab txo.Cov hom phiaj ntawm cov txheej txheem thiab cov kev xav tau yog raws li hauv qab no.
1. perforation
Perforation yog tho ib lub raj rau hauv lub hollow capillary.Cov khoom siv yog hu ua lub tshuab tho: Cov kev xav tau rau cov txheej txheem tho yog:
(1) xyuas kom meej tias cov phab ntsa tuab ntawm cov hlab ntsha uas dhau los ntawm qhov sib xws, lub ovality yog me me, thiab qhov tseeb qhov tseeb ntawm geometrical yog siab;
(2) Sab hauv thiab sab nrauv ntawm lub raj capillary yog tus du, thiab yuav tsum tsis muaj qhov tsis xws luag xws li caws pliav, folding, tawg, thiab lwm yam;
(3) Yuav tsum muaj qhov sib txuas ntawm qhov nrawm nrawm thiab lub voj voog dov kom hloov mus rau qhov kev sib tw ntau lawm ntawm tag nrho chav tsev, kom qhov kawg dov kub ntawm lub raj capillary tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub raj dov zeb.
2. Rolled raj
Lub raj dov yog nias lub perforated tuab-walled capillary raj rau hauv ib lub raj nyias-walled pov tseg kom ua tiav qhov yuav tsum tau thermal loj thiab uniformity ntawm lub tiav lawm raj.Ntawd yog, phab ntsa tuab ntawm cov yeeb nkab pov tseg hauv cov txheej txheem no yog txiav txim siab raws li qhov txo qis ntawm cov txheej txheem tom ntej thiab cov qauv empirical los ua cov txheej txheem phab ntsa tuab.Cov cuab yeej no hu ua yeeb nkab dov zeb.Qhov yuav tsum tau ua rau cov txheej txheem dov lub raj yog: (1) Thaum lub thickness-walled capillary raj yog tig mus rau hauv ib tug nyias-walled pov tseg raj (txo-phab ntsa extension), nws yog tsim nyog los xyuas kom meej tias cov khib nyiab raj muaj ib tug siab dua phab ntsa thickness. tsis sib xws;
(2) Cov yeeb nkab pov tseg muaj qhov zoo sab hauv thiab sab nrauv zoo.Kev xaiv ntawm lub raj zeb zeb thiab qhov tsim nyog sib piv ntawm nws cov deformation nrog cov txheej txheem tho yog qhov tseem ceeb rau kev txiav txim siab qhov zoo, cov zis thiab kev ntsuas thiab kev lag luam ntawm chav tsev.
3. Tsau txoj kab uas hla (xws li txo qhov nro)
Lub luag haujlwm tseem ceeb ntawm kev sizing thiab txo qis yog txhawm rau tshem tawm qhov sib txawv ntawm qhov sib txawv ntawm cov kav dej khib nyiab uas tshwm sim los ntawm cov txheej txheem yav dhau los ntawm kev dov, txhawm rau txhim kho cov kab hluav taws xob sab nraud kom raug thiab roundness ntawm cov yeeb nkab kub dov.Kev txo txoj kab uas hla yog txo cov yeeb nkab loj txoj kab uas hla mus rau qhov yuav tsum tau muaj qhov loj thiab qhov tseeb.Kev txo qis yog txo qis txoj kab uas hla nyob rau hauv qhov kev txiav txim ntawm lub hauv ntej thiab nram qab ncej nro, thiab txo cov phab ntsa tib lub sij hawm.Cov cuab yeej siv rau qhov loj me thiab txo qis yog lub tshuab sizing (txo) .Cov kev xav tau rau kev sizing thiab txo cov txheej txheem yog:
(1) Ua tiav lub hom phiaj ntawm sizing nyob rau hauv cov xwm txheej ntawm ib qho kev txo nqi tag nrho thiab tus nqi txo me me ntawm ib tus ncej;
(2) Nws tuaj yeem paub txog txoj haujlwm ntawm kev siv ib lub raj me me los tsim ntau qhov ntau thiab tsawg ntawm cov raj tiav;
(3) Txuas ntxiv txhim kho qhov zoo ntawm cov yeeb nkab steel.
