Raw material ahosiesie: Wɔpaw dade billets (te sɛ casting billets a ɛkɔ so) sɛ raw material na wɔhwɛ ne su (sɛ nhwɛso no, ma mpaapaemu ne nea ɛka ho).
Ɔhyew: Wɔde billets no yɛ hyew wɔ ɔhyew fononoo mu ma ɛyɛ hyew (hot rolling hwehwɛ sɛ ɛyɛ hyew kɛse, bere a cold rolling nhia ɔhyew).
Rolling: .
Hot Rolling: Wɔbobɔ billet a ɛyɛ hyew no mu fa owiyammo a ɛyɛ mmerɛw mu kɔ mfinimfini billet mu, na afei wɔbobɔw fa owiyammo a wɔde wie mu kɔ nea wɔde asi wɔn ani so no kɛse ne ne tɛtrɛtɛ so. Wɔ saa adeyɛ yi mu no, ɛsɛ sɛ wɔhwɛ ahoɔhare ne ɔhyew a ɛkɔ so no so na ama wɔahwɛ ahu sɛ nneɛma a ɛyɛ pɛ.
Cold Rolling: Sɛ wode hot-rolled coil di dwuma sɛ raw material a, wɔde ade no hyɛ rolling passes pii ase wɔ dan mu hyew mu (te sɛ owiyammo a wɔdannan no) na ama ayɛ kɛse bere a ɛma asase ani a wɔde wie ne ahoɔden tu mpɔn no.
Onwini ne coiling: .
Hot-Rolled Coil: Sɛ wobobɔw wie a, wɔde laminar cooling system di dwuma no ma ɛyɛ nwini wɔ rate a wɔahyɛ so ansa na wɔde coiler ayɛ no coiled.
Cold-Rolled Coil: Sɛ wobobɔw wie a, wɔde aduru no hyɛ mu tẽẽ, na afã horow bi fa annealing mu (de yi nhyɛso fi mu na ɛma toughness tu mpɔn).
Nneɛma a wɔyɛ no akyiri yi: Wɔyɛ pickling, galvanizing, color coating, cutting ne afoforo a wɔyɛ no sɛnea ahiade ahorow te sɛ nea etwa to no.
