Dab tsi yog kub-dov, dab tsi yog txias-dov, thiab qhov sib txawv ntawm ob?

 

1. Kub Rolling
Nruam casting slabs los yog thawj zaug yob slabs li cov ntaub ntawv roughosphorization, Tail, thiab tom qab ntawd mus rau lub pob zeb tiav, kev siv ntawm lub computer- Kev tswj hwm dov, qhov kawg dov uas yog tom qab laminar ntws txias (khoos phis tawj coiling) thiab coiling tshuab coiling, ua kom ncaj cov plaub hau yob. Lub taub hau thiab tus Tsov tus tw ntawm cov plaub hau ncaj feem ntau yog tus nplaig thiab cov nplaim taws, muaj feem ntau yoj-zoo li ntug, ntauwd ntug, ntauwd thiab lwm yam tsis xws luag. Nws lub ntim hnyav yog hnyav, lub taub sab hauv ntawm cov hlau chev yog 760mm. (General Yeeb Nkab Ua Kev Lag Luam Zoo li siv.) Cov plaub hau ncaj coil los ntawm kev ua lub taub hau, thiab tom qab ntawd txiav phaj lossis rov qab txiav, uas yog los ua: kub Rolled steel phaj, tiaj tus kub dov steel coils, ntev txiav sawb thiab lwm yam khoom. Kub cov co coils yog tias tus pickling kom tshem tawm cov tawv nqaij oxide thiab roj roj rau hauv kub dov cheil. Daim duab hauv qab no qhia covKub Rolled kauj.

 

2. Ntxhw dov
Kub Rolled Steel coils li cov ntaub ntawv raw, tom qab cov tawv nqaij tawm los ntawm cov tawv nqaij qhuav, vim cov khoom siv tau txias rau lub zog txias, tawv tawv, tawv thiab yas Qhov ntsuas kev poob qis, Stamping kev ua haujlwm tsis zoo, tsuas siv tau rau kev deformation yooj yim ntawm feem. Rolled tawv tawv tuaj yeem siv los ua cov ntaub ntawv raw rau kub-dip galvanizing cog, vim tias kub-dip galvanizing chav tsev tau teeb tsa nrog anealing kab. Rolled nyuaj chev hnyav yog feem ntau 6 ~ 13.5 tons, lub inner inter ntawm lub kauj yog 610 hli. JENERALL txias rolled phaj, kauj yuav tsum tau txuas ntxiv mus tas li (khaws cia kev ntxhov siab, kom ua tiav cov khoom siv txias, kom ua tiav cov khoom siv tshuab tau teev nyob hauv cov qauv txheem. Txias dov steel phaj zoo, tsos, qhov tseeb yog qhov zoo dua li kub dov phaj. Daim duab hauv qab no qhia txogCuav Rolled Chev.

 

Lub ntsiab sib txawv ntawmkhaub thuas dov vs kub dov hlauCov lus dag hauv kev ua thev naus laus zis, cov khoom siv ntawm daim ntawv thov, cov khoom siv mechanical thiab cov khoom zoo, nrog rau tus nqi sib txawv. Cov hauv qab no yog cov lus qhia ntxaws ntxaws:
Ua. Kub dov yog ua tiav ntawm cov kub, thaum txias dov ua tiav ntawm chav tsev kub. Kub dov yog dov saum toj no cov crystallization kub, thaum txias dov yog dov hauv qab lub crystallization kub.

 
Cov ntawv thov. Kub Rolled steel yog tsuas yog siv nyob rau hauv cov qauv steel lossis cov khoom siv tshuab, tshuab ntxhua khaub ncaws, tshuab ntxhua khaub ncaws, txias, thiab lwm yam.

 
Cov khoom siv neeg kho tshuab. Txias zog cov khoom siv yog feem ntau zoo dua li kub yob, tab sis lub zog txias dua, tab sis lub zog txias dua, thaum cov khoom siv tshuab hluav taws xob ntawm cov ntawv kub yog deb tsawg dua cov ntawv txias colded, tab sis muaj qhov muaj zog zoo dua thiab ductility.

 
Zoo. Qhov zoo ntawm cov qauv txheej txheem ntawm cov khaub thuas txias yuav zoo dua li kub dov thiab cov khoom txias heev, thaum kub cov khoom muaj cov khoom siv kub.

 
Kev tshwj xeeb cov tuab tuab. Txias lub coils feem ntau yog nyias nyias cov coils, nrog rau cov tuab tuab ntawm 0.3 mus rau 3.5 rolled coils los ntawm 1.2 txog 25.4 millimeters.

Nqe: Feem ntau, dov tawm yog me ntsis kim dua kub dov. Qhov no yog vim tias colding txias yuav tsum tau siv cov cuab yeej siv ntau tshaj plaws thiab cov khoom siv txias ntau dua, yog li cov khoom siv txias kom tau txais cov khoom txias zoo dua li, tus nqi yog qhov siab dua. Tsis tas li ntawd, cov hlau txias rolled steel nyob rau hauv cov txheej txheem ntau lawm, yob cov khoom siv tau ntau dua, uas tseem yuav ua rau muaj kev nce siab hauv cov nqi ntau lawm.
