Kufotokozera Kwachidule:

Dzina: Cold Rolled Steel Coil

Chitsulo chozizira cha carbon (SPCC, SPCD, SPCE), chitsulo chochepa cha carbon ndi zitsulo zotsika kwambiri za carbon (DC01/St12, DC03/St13, DC04/St14), zitsulo zosindikizira zamagalimoto (DC01-Q1, DC03-Q1, DC04 - Q1), zingwe zazitsulo zozizira za carbon structural (Q235, St37-2G, S215G), zingwe zachitsulo zotsika kwambiri zozizira (JG300LA, JG340LA), ndi zina zotero.

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

Mawonekedwe: Chifukwa sichimatsekeka, kuuma kwake ndikokwera kwambiri (HRB ndi yayikulu kuposa 90), ndipo magwiridwe antchito amakina ndi osauka kwambiri.Njira yosavuta yokhotakhota yochepera madigiri 90 (perpendicular to makhonde njira) ingachitike.Zitsulo zina zimatha kupanga makina anayi.

Chidule cha koyilo yoziziritsa yozizira

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.

Njira Yopangira Cold Rolled Coil

Chophimba chozizira chozizira chimapangidwa ndi koyilo yotentha yotentha, ndipo njira yake yopangira nthawi zambiri imadutsa njira zazikulu monga kukonzekera zopangira, kuzizira kozizira, kutentha kutentha, kusanja ndi kumaliza.

Ntchito ya Cold Rolled Coil Product

Mpukutu ndi piritsi ndi pafupifupi phukusi lodulidwa.The ozizira koyilo anapezedwa pickling ndi ozizira akugudubuza otentha adagulung'undisa koyilo.Tinganene kuti ndi mtundu ozizira adagulung'undisa koyilo.Cold rolling coil (annealed state): Koyilo yotenthedwa yotentha imapezedwa ndi pickling, kugudubuza kozizira, kutsekereza hood, kusanja, (kumaliza).

Pali kusiyana kwakukulu 3 pakati pawo:

M'mawonekedwe, koyilo yozizira kwambiri imakhala yosalala pang'ono.

Mapepala oziziritsa ozizira monga mawonekedwe apamwamba, kapangidwe kake ndi kulondola kwake ndikwabwino kuposa ma koyilo ozizira.

Pankhani ya magwiridwe antchito, koyilo yoziziritsa bwino yomwe imapezeka mwachindunji pambuyo pa kuzizira kozizira kwa koyilo yopindika yotentha imagwira ntchito molimba panthawi yozizira, zomwe zimapangitsa kuwonjezeka kwa mphamvu zokolola komanso gawo lina la kupsinjika kwamkati komwe kumatsalira, ndipo mawonekedwe akunja ndi "ovuta". ".Amatchedwa chilled coil.

Chifukwa chake, mphamvu yokolola: koyilo yozizira ndi yayikulu kuposa koyilo yozizira-yozizira (boma lopindika), kotero kuti koyilo yoziziritsa kuzizira (boma la annealed) imakhala yabwino kwambiri kupondaponda.Nthawi zambiri, mawonekedwe osasinthika a ma coil ozunguliridwa ozizira amachotsedwa.
