Ts'ebetso ea tlhahiso ea li-coil tsa tšepe tse chesang ke ntho e ka sehloohong ea ho etsa tšepe. Haholo-holo e etsa billet ea tšepe ka har'a sebopeho se hlokahalang sa poleiti ka ho roala ha mocheso o phahameng. Tse latelang ke mehato ea eona ea mantlha:
Tokisetso ea Lintho tse tala
Sebelisa billet e sa khaotseng kapa billet ea pele ea rolling e le thepa e tala, 'me botenya ba billet hangata ke 150-300mm.
Billet e hloekisoa holim'a metsi (joalo ka ho hloekisa lelakabe kapa ho sila ka mochine) ho tlosa oxide scale le liphoso ho netefatsa boleng ba ho roala.
Ho futhumatsa
Billet e romelloa sebōping se futhumatsang sa mohato 'me se futhumetse ho 1100-1300 ℃ ho etsa hore billet e fihle mocheso oa austenitizing le ho ntlafatsa polasetiki.
