Chidule cha Cold Rolled Steel Coil

Chophimba chozungulira chozizira chimapangidwa ndi chophimba chozungulira chotentha. Mu ndondomeko yozungulira yozizira, chophimba chozungulira chotentha chimakulungidwa pansi pa kutentha kwa recrystallization, ndipo chitsulo chozungulira nthawi zambiri chimakulungidwa kutentha kwa chipinda. Chitsulo chokhala ndi silicon yambiri chimakhala ndi kufooka kochepa komanso pulasitiki yochepa, ndipo chimayenera kutenthedwa mpaka 200 °C chisanakulungidwe chozizira. Popeza chophimba chozungulira chozizira sichitenthedwa panthawi yopanga, palibe zolakwika monga pitting ndi iron oxide zomwe nthawi zambiri zimapezeka mu chophimba chotentha, ndipo mawonekedwe a pamwamba ndi kumaliza kwake ndi zabwino.

Koyilo Wozizira Wopindika

1. Mtundu wa ku China Nambala Q195, Q215, Q235, Q275——Q—khodi ya mfundo yoyambira (malire) ya chitsulo chokhazikika cha kaboni, chomwe chili ngati zilembo zoyambirira za mawu achi China za "Qu"; 195, 215, 235, 255, 275 - motsatana ikuyimira mtengo wa mfundo yawo yoyambira (malire), gawo: MPa MPa (N / mm2); chifukwa cha mphamvu ya makina yonse ya Q235 yachitsulo, pulasitiki, kulimba ndi kusunthika mu chitsulo chokhazikika cha kaboni. Kwambiri, imatha kukwaniritsa bwino zofunikira zonse zogwiritsidwa ntchito, kotero kuchuluka kwa ntchito ndi kwakukulu kwambiri.
2. Mtundu wa ku Japan wa SPCC - Chitsulo, P-Plate, C-cold, C-common wachinayi.
3. Germany grade ST12 - ST-steel (Chitsulo), pepala lachitsulo lozizidwa la makalasi 12.

Kugwiritsa Ntchito Cold Rolled Steel Coil

Chozungulira chozizira chimakhala ndi magwiridwe antchito abwino, kutanthauza kuti, kudzera mu kuzizira kozungulira, mzere wozungulira wozizira ndi pepala lachitsulo lokhala ndi makulidwe owonda komanso kulondola kwambiri lingapezeke, lolunjika kwambiri, losalala kwambiri pamwamba, pamwamba poyera komanso lowala la pepala lozungulira lozizira, komanso losavuta kuphimba. Kukonza kokutidwa, mitundu yosiyanasiyana, kugwiritsidwa ntchito kwambiri, komanso mawonekedwe a magwiridwe antchito apamwamba komanso osakalamba, otsika phindu, kotero pepala lozungulira lozizira lili ndi ntchito zosiyanasiyana, zomwe zimagwiritsidwa ntchito makamaka m'magalimoto, ng'oma zachitsulo zosindikizidwa, zomangamanga, zipangizo zomangira, njinga, ndi zina zotero. Makampaniwa ndi omwenso ndi chisankho chabwino kwambiri popanga mapepala achitsulo okhala ndi organic.
