Coiled phaj thiab kub - rolled chev yog ob yam khoom sib txawv steel. Coiled phaj yog tas lawm hlau, coj los ntawm zoo heev nto moo zoo thiab siab qhov tseeb raug. Kub - rolled chev, ntawm qhov tod tes ua los ntawm billets raug rau siab- kub dauv. Nws qhov chaw zoo yog cov neeg tsis zoo thiab nws qhov tseeb qhov tseeb yog qhov tsawg. Cov kev sib txawv tshwj xeeb yog raws li hauv qab no:
1. Cov tswv yim sib txawv
Coiled phaj yog tsim los ntawm kev ntxhib, nruab nrab, thiab cov milling tiav. Tom qab ntau dua yob hla, nws ua tiav ib tug du, wrinkle -} dawb nto thiab ruaj khov qhov ntev thiab ruaj khov. Kub - rolled chev, ntawm qhov tod tes, yog tsim los ntawm high- kub dhuav, burrs thiab tsis ruaj khov sab ruaj khov.
2. Cov ntawv thov sib txawv
Coiled phaj muaj feem ntau siv nyob rau hauv kev tsim cov qauv steel, qhov khoom siv tsheb, thiab cov khoom siv hauv tsev, thiab tuaj yeem yog galvanized lossis pleev xim. Kub {{{}}} rolled chev, ntawm qhov tod tes, feem ntau yog cov kav dej uas xav tau khoov thiab nias- kev sib sau.
3. Kev ua tau zoo sib txawv
Rolled steel coils yog tus nyias, tab sis pom pom muaj kev tsim kho zoo, kev sib zog, thiab weldability. Kub {- rolled steel co yog thicker, tab sis ua rau muaj zog dua thiab lub zog.
