Kakaretso ea Cold Rolled Steel Coil
Mohatsela o batang o entsoe ka khoele e kolobisitsoeng e chesang. Ts'ebetsong e batang, coil e chesang e phuthoa ka tlase ho mocheso oa recrystallization, 'me tšepe e phuthetsoeng ka kakaretso e phuthoa ka mocheso oa kamore. Letlapa la tšepe le nang le silicon e phahameng le na le brittleness e tlase le polasetiki e tlase, 'me e hloka ho futhumatsoa pele ho 200 ° C pele ho bata. Kaha coil e pholileng e batang ha e futhumale nakong ea tlhahiso, ha ho na liphoso tse kang pitting le iron oxide tse atisang ho fumanoa ka ho chesa ho chesang, 'me boleng ba holim'a metsi le ho qetela li ntle.
