makulidwe osiyanasiyana: 0.1mm-0.45mm

m'lifupi osiyanasiyana: 700mm-1000mm

Zida: SPCC, SPCC, SPCD, SPCE, DC01, St12, DC03, St13, DC04, St14, Q235, St37-2G, S215G, JG300LA, JG340LA

Zinthu Zake: Popeza sichinatsekedwe, kuuma kwake ndi kwakukulu kwambiri (HRB ndi yayikulu kuposa 90), ndipo magwiridwe antchito ake ndi otsika kwambiri. Njira yosavuta yokhota yolunjika yochepera madigiri 90 (yolunjika ku mbali yokhota) ndi yomwe ingachitike. Mafakitale ena achitsulo amatha kupanga njira zinayi zogwirira ntchito.

Chidule cha coil yozizira yozungulira

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.

Njira Yopangira Koyilo Yozizira Yozungulira

Chophimba chozungulira chozizira chimapangidwa ndi chophimba chozungulira chotentha, ndipo njira yopangira yake nthawi zambiri imadutsa munjira zazikulu monga kukonzekera zinthu zopangira, kuphimba kozizira, kuchiza kutentha, kulinganiza ndi kumaliza.

Magwiridwe antchito a Cold Rolled Coil Product

Mpukutu ndi piritsi zili ngati phukusi lodulidwa. Chophimba chozizira chimapezeka pochipukuta ndi kupukusa chophimba chotentha chozizira. Tinganene kuti ndi mtundu wa chophimba chozizira chopukusa. Chophimba chozizira chopukusa (mkhalidwe wotsekedwa): Chophimba chotentha chopukusa chimapezeka pochipukuta, kupukusa kozizira, kupukusa hood, kulinganiza, (kumaliza).

Pali kusiyana kwakukulu kutatu pakati pawo:

M'mawonekedwe ake, chozungulira chozizira chimakhala chosalala pang'ono.

Mapepala ozungulira ozizira monga ubwino wa pamwamba, kapangidwe kake ndi kulondola kwa miyeso ndi abwino kuposa ma coil ozizira.

Ponena za magwiridwe antchito, coil yozizira yomwe imapezeka nthawi yomweyo pambuyo poyimitsa kozizira ya coil yotentha yozungulira imalimbikitsidwa panthawi yoyimitsa kozizira, zomwe zimapangitsa kuti mphamvu yokolola ikhale yowonjezereka komanso gawo la kupsinjika kwamkati lizitsalira, ndipo mawonekedwe akunja ndi "olimba". Amatchedwa coil yozizira.

Chifukwa chake, mphamvu yobereka: coil yozizira ndi yayikulu kuposa coil yozizira (state annealed), kotero coil yozizira (state annealed) ndi yabwino kwambiri popaka stamping. Kawirikawiri, mkhalidwe wokhazikika wa coil yozizira imayikidwa annealed.

Makampaniwa ndi omwenso ndi chisankho chabwino kwambiri popanga mapepala achitsulo okhala ndi organic.

Mitundu ya ntchito:
(1) Kukonza zinthu kuti zikhale zozizira zomwe zimazungulira pambuyo poziphimba;
(2) Chipangizo chopangira ma galvanizing chokhala ndi chipangizo chokonzera ma annealing chimakonzedwa kuti chigwiritsidwe ntchito ngati ma galvanizing;
(3) Mapanelo omwe safuna kukonzedwa konse.
