Chidule cha Cold Rolled Steel Coil

Chophimba chozizira chozizira chimapangidwa ndi koyilo yotentha yotentha.Mu ndondomeko ozizira adagulung'undisa, otentha adagulung'undisa koyilo ndi adagulung'undisa pansi recrystallization kutentha, ndi chitsulo ambiri adagulung'undisa ndi adagulung'undisa kutentha firiji.Chitsulo chokhala ndi silicon yambiri chimakhala ndi brittleness yochepa komanso pulasitiki yotsika, ndipo chiyenera kutenthedwa mpaka 200 ° C chisanayambe kuzizira.Popeza kuti koyilo yozizira yozungulira sikutenthedwa panthawi yopanga, palibe zolakwika monga pitting ndi iron oxide yomwe nthawi zambiri imapezeka pakugudubuza kotentha, ndipo mawonekedwe apamwamba ndi mapeto ake ndi abwino.
