Kub- dov steel kauj yog tsim los ntawm slabs (feem ntau tsis tu ncua slabs) ua raw khoom; Tom qab tau rhuab nyob rau hauv ib tug reheating rauv (los yog homogenized nyob rau hauv ib tug soaking qhov), cov khoom yog dov mus rau hauv steel sawb los ntawm roughing thiab finishing zeb tsheb ciav hlau.
Kub- dov steel coil khoom feem ntau suav nrog nruab nrab- mus rau - tuab steel sawb, nyias dav kub - dov steel sawb, thiab kub- dov daim ntawv. Nruab nrab-rau- tuab dav steel sawb hais txog steel sawb nrog lub thickness ntawm ntau dua los yog sib npaug li 3 hli tab sis<20 mm and a width of ≥600 mm, produced using equipment such as continuous wide-strip hot rolling mills or furnace-coil mills, and delivered in coil form. Thin wide hot-rolled steel strip refers to steel strip with a specific thickness (typically <3 mm) and a width of ≥600 mm, produced using equipment such as continuous wide-strip hot rolling mills, furnace-coil mills, or thin-slab continuous rolling lines, and delivered in coil form. Hot-rolled sheet refers to individual steel plates of a specific thickness.
Raws li qhov sib txawv ntawm cov khoom muaj pes tsawg leeg thiab cov khoom siv kho tshuab, kub- dov steel coils tuaj yeem muab faib ua cov qauv carbon zoo tib yam, qis- alloy steel, thiab hlau alloy. Raws li lawv cov kev xav tau, lawv tuaj yeem muab faib ua cov hlau rau kev ua kom txias, cov qauv hlau, cov khoom siv hauv tsheb, cov khoom siv hlau, corrosion-cov qauv steel, steels rau cov khoom siv tshuab, steels rau welded gas cylinders thiab siab hlab ntsha, pipeline steels, thiab lwm yam.
