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 coil yozizira yozungulira sichitenthedwa panthawi yopanga, palibe zolakwika monga pitting ndi iron oxide yomwe nthawi zambiri imapezeka pakugudubuzika kotentha, ndipo mawonekedwe apamwamba ndi mapeto ake ndi abwino.

Kugwiritsa Ntchito Cold Rolled Steel Coil

Chophimba chozizira chozizira chimakhala ndi ntchito yabwino, ndiko kuti, kupyolera mu kugudubuza kozizira, mzere wozizira wozizira ndi pepala lachitsulo lokhala ndi makulidwe ochepa komanso olondola kwambiri angapezeke, ndi owongoka kwambiri, osalala kwambiri, oyera komanso owala pamwamba pa pepala lozizira. , ndi kupaka kosavuta. The yokutidwa processing, zosiyanasiyana, ntchito lonse, ndi makhalidwe a mkulu masitampu ntchito ndi sanali ukalamba, otsika zokolola mfundo, ozizira adagulung'undisa pepala ali osiyanasiyana ntchito, makamaka ntchito magalimoto, kusindikizidwa zitsulo ng'oma, zomangamanga, zomangira, njinga, etc. Makampani ndi njira yabwino kwambiri yopangira mapepala achitsulo opangidwa ndi organic.
