Cold dov steel kaujyog hais txog lub steel strip uas ncaj nraim dov mus rau hauv ib tug tej thickness los ntawm ib tug dov zeb nyob rau hauv chav tsev kub thiab ces dov mus rau hauv ib tug tag nrho yob los ntawm ib tug winding tshuab. Piv rau cov kub dov coils, txias dov coils muaj qhov ci ntsa iab thiab siab smoothness, tab sis lawv tsim muaj kev ntxhov siab ntau dua thiab feem ntau annealed tom qab txias dov. Lub composition ntawm atxias dov steel kauj Hoobkasyog txiav txim los ntawm cov khoom tsim, thiab cov yam ntxwv ntawm cov khoom txiav txim siab cov txheej txheem ntau lawm. Piv txwv li, hauv kev tsim cov ntawv hlau galvanized, cov txheej txheem suav nrog pickling, txias dov, annealing, galvanizing, leveling, hla txiav, thiab ntim khoom. Cov txheej txheem ntau lawm ntawm txias dov steel kauj yog raws li nram no:
① Kev thauj mus los ntawm cov khoom siv rawKub Rolled Coilkoom nrog qhov kev ncua deb ntawm ob peb puas meters los ntawm lub rooj cob qhia mus rau qhov chaw ua haujlwm txias dov, uas yog ib qho tseem ceeb ntawm cov txheej txheem. Muaj ntau txoj kev thauj mus los, xws li tsheb, tsheb ciav hlau, cov menyuam conveyors, taug kev kab, saw conveyors, thiab lwm yam. Yog tias cov khoom siv tsis yog cov qauv siv los ua cov cuab yeej thauj mus los.
② Acid ntxuav lub hom phiaj kom tshem tawm oxide nplai thiab cov roj stains los ntawm qhov chaw ntawm kub dov sawb hlau.
③ Rolling yog cov txheej txheem tseem ceeb hauv kev siv tshuab txias txias, uas feem ntau ua haujlwm rau nyias cov hlua hlau los ntawm kev dov, ua tiav cov txheej txheem tuab, txhim kho cov khoom siv ntawm cov sawb hlau, thiab txhim kho qhov zoo thiab zoo ntawm cov sawb hlau.
④ Kev kho mob,txias dov steel kaujundergoes txias ua hauj lwm hardening vim muaj zog txias deformation thaum lub sij hawm dov txheej txheem, ua rau nws tsis tsim nyog rau kev ua hauj lwm ntxiv thiab yuav tsum tau kev kho cua sov kom tshem tawm cov kev ntxhov siab nyob rau hauv.
⑤ Leveling ua hauj lwm tau muab faib ua ib leeg sawv ntsug thiab ob chav sawv ntsug. Kev ua haujlwm ntawm ib leeg sawv ntsug tsuas yog txhawm rau txhim kho qhov zoo ntawm qhov chaw thiab qee yam khoom siv ntawm cov hlua hlau, thaum ob chav sawv ntsug yog tias ib qho dov zeb ua tiav cov haujlwm ntawm ib leeg sawv ntsug, thiab lwm qhov dov zeb ua tiav cov haujlwm dov, uas yuav tsum tau me me ntawm thinning ntawm strip steel thickness (xws li tin plated sawb hlau).
⑥ Cold rolled steel coil deg txheej tuaj yeem muaj ntau txheej txheej tiv thaiv ntawm cov hlau nplaum raws li qhov sib txawv. Cov khoom siv feem ntau yog galvanizing, tin plating, chrome plating, thiab xim plating. Galvanizing, tin plating, thiab chrome plating tuaj yeem ua los ntawm cov cua sov, uas txhais tau hais tias siv cov kua nplaum ntawm cov tin, zinc, thiab chromium kom sib npaug ntawm cov hlau nplaum. Txawm li cas los xij, electroplating tseem tuaj yeem siv los txuas cov txheej nyias ntawm cov hlau rau saum npoo ntawm cov hlau, thiab cov xim plating feem ntau yog ua los ntawm cov menyuam, qhov chaw cov menyuam nto dipped nyob rau hauv cov xim yog coated rau saum npoo ntawm steel sawb.
⑦ Kev tshuaj xyuas rau rewinding yog ib txoj hauv kev faib cov yob ua tiav rau hauv ntau lub yob ua lag luam thiab ua cov khoom lag luam kuaj xyuas ib txhij.
⑧ Txiav kom ntev, txias dov steel kauj yog txiav rau hauv daim hlau thaiv raws li qhov xav tau ntev.
⑨ Strip steel longitudinal txiav, txias dov steel coil txiav cov sawb hlau rau hauv ntau qhov nqaim strip coils raws li qhov xav tau dav.
⑩ Cov ntim khoom tiav, txawm tias nws yog ib pawg ntawm cov laug cam txiav rau hauv ntu lossis nqaim strip yob, yuav tsum tau ntim khoom ua ntej muab tso rau hauv kev ua lag luam.
Cov txheej txheem tsim khoom saum toj no yeej suav nrog cov txheej txheem tsim khoom hauv cov chaw ua haujlwm txias txias txias steel coil, tab sis tsis tau txhais hais tias txhua lub chaw tsim khoom yuav tsum muaj cov ntsiab lus no, tab sis cov ntsiab lus ntawm cov txheej txheem tau teeb tsa raws li cov khoom xav tau.
