Raw Material Preparation: Steel billet (continuous casting billet ang chi) te chu raw material atan thlan a ni a, an quality chu enfiah a ni (eg, crack leh inclusions te tan).
Heating: Billets te hi heating furnace-ah rolling temperature thlengin an lum a (hot rolling hian temperature sang a mamawh a, cold rolling erawh chuan heating a ngai lo).
Rolling tih hi a ni.
Hot Rolling: Billet hot chu roughing mill hmangin intermediate billet-ah an roll a, chu chu finishing mill kaltlangin target thickness leh width thlengin an roll a. Hetiang a nih lai hian rolling speed leh temperature chu uniform property a awm theih nan control a ngai a ni.
Cold Rolling: Hot-rolled coil chu raw material atan hmangin, product chu room temperature-ah (reversing mill ang chi) rolling pass tam tak a awm a, chu chuan surface finish leh strength a ti tha a, a thickness a ti tlem bawk.
Cooling leh coiling:
Hot-Rolled Coil: Rolling zawhah coiler hmanga coil hmain laminar cooling system hmangin controlled rate-in product chu controlled rate-in a lum a.
Cold-rolled coil: Rolling zawhah chuan product chu direct-in coil a ni a, a then chu annealing (internal stress tihbo leh toughness tihchangtlun nan) a awm bawk.
A hnuaia processing: Pickling, galvanizing, color coating, cutting leh processing dangte chu a tawp bera siam tur chuan a tul angin an ti thin.
