Cov txheej txheem txias-dov coil tsim muaj ntau theem uas hloov cov kub-kuav los yog kua qaub-ntxuav steel kauj mus rau hauv ib lub thinner, smoother txias-dov cov khoom nrog txhim kho nto tiav thiab qhov tseeb. Ntawm no yog ib qho kev piav qhia ntawm cov kauj ruam nyob rau hauv cov txheej txheem txias-dov coil:
Kev xaiv raw khoom:
Cov txheej txheem pib nrog kev xaiv cov ntaub ntawv tsim nyog, uas feem ntau yog kub dov los yog pickled steel coils. Cov ntaub ntawv no paub txog lawv qhov zoo ntawm qhov chaw tiav thiab cov tuab tuab.
Nthuav:
Cov coil xaiv tau yog thawj zaug unrolled rau siv nyob rau hauv lub nruam dov txheej txheem. Qhov no suav nrog unrolling thiab straightening lub coil kom ntseeg tau tias zoo ib yam pub rau lub zeb.
Txias Rolling:
Lub uncoilable sawb hla los ntawm ib tug series ntawm yob sawv nyob rau hauv ib tug txias zeb. Cov hlua khi no maj mam txo cov tuab ntawm cov hlau thaum txhim kho nws qhov chaw tiav. Txias dov yog nqa tawm ntawm chav tsev kub, thiab cov txheej txheem no muab cov hlau nws lub zog thiab flatness.
Annealing (yeem):
Qee zaum, txias dov hlau yuav raug muab tshem tawm. Annealing muaj cua sov hlau mus rau qhov kub thiab txias thiab maj mam txias. Cov txheej txheem no tuaj yeem txhim kho cov ductility ntawm cov hlau thiab tshem tawm cov kev ntxhov siab seem.
Txiav thiab slitting:
Tom qab txias dov txheej txheem, cov hlau sawb yog txiav rau hauv yob ntawm qhov xav tau dav los yog txiav mus rau hauv nyias strips, nyob ntawm seb cov neeg siv khoom xav tau.
Finishing thiab tshuaj xyuas:
Lub yob los yog sawb tuaj yeem muab txiav kom tshem tawm cov npoo tsis zoo lossis qhov tsis zoo. Kev tshuaj xyuas zoo yog ua los xyuas kom meej tias cov khoom tiav ua tau raws li qhov yuav tsum tau ua ntawm thickness, nto tiav thiab flatness.
Packing thiab shipping:
Cold-rolled coils lossis strips tau ntim thiab npaj xa mus rau cov neeg siv khoom lossis cov chaw tsim khoom hauv qab. Thaum lub sij hawm kev thauj mus los, lawv feem ntau yog nruj nreem kaw rau hauv coils thiab securely strapped los yog qhwv rau kev tiv thaiv.
Cov txheej txheem txias dov coj ntau yam txiaj ntsig rau cov hlau, suav nrog kev txhim kho saum npoo zoo, qhov tseeb qhov tseeb thiab cov khoom siv kho tshuab. Cold-dov hlau yog feem ntau siv nyob rau hauv ntau yam lag luam xws li tsheb tsim, kev tsim kho, khoom siv hauv tsev, thiab lwm yam., qhov precision thiab zoo yog qhov tseem ceeb.
