1. Taw qhia
Lub taub hau thiab tus Tsov tus tw ntawm cov plaub hau ncaj curler feem ntau yog tus nplaig-zoo li tus ntses-tail-puab, nrog cov tuab tuab thiab dav qhov tseeb, thiab cov npoo feem ntau muaj qhov tsis xws luag xws li yoj duab, folded ntug, thiab ntauwd duab. Nws qhov hnyav yob hnyav dua. (Feem ntau cov yeeb nkab kev lag luam nyiam siv nws.)
2. Siv
Cov khoom kub dov muaj cov khoom zoo xws li lub zog siab, zoo toughness, ua tau yooj yim thiab zoo weldability, yog li lawv tau dav siv hauv kev lag luam xws li steel, kev tsim kho, machinery, boilers, thiab siab hlab ntsha.
Kev siv ntau yam:
(1) Tom qab annealing, nws tau ua tiav rau hauv qhov txias txias dov;
(2) Lub tsev galvanizing nrog pre-annealing kho cov txheej txheem galvanizing;
(3) Cov vaj huam sib luag uas tsis tas yuav tsum tau ua tiav.
3. Kev faib tawm
Common carbon phaj, zoo heev carbon phaj, tsis tshua muaj hlau phaj, nkoj phaj, choj phaj, boiler phaj, thawv phaj, thiab lwm yam. Hard-dov coils: Nruam dov kub dov pickled coils ntawm chav tsev kub.
Kub nruam dov steel ntawv cov khoom muaj xws li steel strips (coils) thiab steel ntawv txiav los ntawm lawv. Cov hlau sawb (yob) tuaj yeem muab faib ua cov plaub hau ncaj thiab ua tiav cov yob (sib faib yob, tiaj tus yob thiab slitting yob)
