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.

Cold adagulung'undisa Coil Kalasi
1. Mtundu waku China No. Q195, Q215, Q235, Q275——Q—kodi ya zokolola (malire) achitsulo wamba wa carbon structural steel, womwe ndi nkhani ya zilembo zoyambirira zamafonetiki zaku China za "Qu"; 195, 215, 235, 255, 275 - motero amaimira mtengo wa zokolola zawo (malire), unit: MPa MPa (N / mm2); chifukwa mabuku mawotchi zimatha Q235 zitsulo mphamvu, plasticity, kulimba ndi weldability wamba mpweya structural zitsulo Kwambiri, akhoza bwino kukumana ndi zofunika zonse ntchito, kotero kukula kwa ntchito ndi lalikulu kwambiri.
2. Mtundu waku Japan SPCC - Chitsulo, P-Plate, C-ozizira, wachinayi C-wamba.
3. Germany kalasi ST12 - ST-zitsulo (Zitsulo), 12-kalasi ozizira adagulung'undisa zitsulo pepala.
Kugwiritsa ntchito Cold Rolled Steel Coil
Chophimba chozizira chozizira chimakhala ndi ntchito yabwino, ndiko kuti, kupyolera mu kuzizira kozizira, kuzizira kozizira ndi pepala lachitsulo ndi makulidwe ochepetsetsa komanso kulondola kwapamwamba kungapezeke, ndi kuwongoka kwakukulu, kusalala kwapamwamba, kuyera ndi kowala pamwamba pa pepala lozizira lozizira, ndi kuvala kosavuta. The yokutidwa processing, zosiyanasiyana, lonse ntchito, ndi makhalidwe a mkulu zisindikizo ntchito ndi sanali ukalamba, otsika zokolola mfundo, kotero ozizira adagulung'undisa pepala ali osiyanasiyana ntchito, makamaka ntchito magalimoto, kusindikizidwa ng'oma chitsulo, yomanga, zomangira, njinga, etc. Makampani ndi kusankha bwino kwa kupanga mapepala organic TACHIMATA zitsulo.
