Hot rolled coil, which is made of slab (mainly continuous casting billet) as raw material, is heated and then made into strip by roughing and finishing rolling units. Umucu oshisayo osuka emshinini wokugcina wesigayo upholiswa ngokugeleza kwe-laminar kumazinga okushisa amisiwe futhi igoqwe ibe ikhoyili ye-strip yikhoyili, kanye nekhoyili epholile.

Hot-rolled steel coils/plates are steels made by high-temperature heating and rolling. Its strength is not very high, but its plasticity and weldability are good. I-hot rolling ingathuthukisa ukusebenza kwezinsimbi nama-alloys, iphule izinhlamvu ezimahhadla esimweni sokusakazwa, kupholise imifantu, kunciphise noma kuqede amaphutha okusakaza, kuguqule ukwakheka kwe-as-cast kube isakhiwo esikhubazekile, futhi kuthuthukise ukusebenza komshini. alloy.
