ERW Carbon Steel Groove Black&HDG Pipe

1. Zofunikira za ziwirizi ndizosiyana
(1) Chofunikira chachitsulo chozizira: Chitsulo chozizira ndi chitsulo chomwe chimapangidwa ndi chitsulo chozizira.Kugudubuza kozizira ndi njira yopititsiranso chitsulo chachitsulo kuti chikhale chokhuthala ndi kutentha kozizira.
(2) Chofunika kwambiri chachitsulo choyaka moto: Chitsulo chotentha ndi mtundu wachitsulo chokulungidwa pamwamba pa kutentha kwa recrystallization.

2. Makhalidwe a awiriwa ndi osiyana
(1) Mawonekedwe a zitsulo zozizira zozizira: Kukhuthala kwa mbale zoziziritsa kuzizira kumakhala kolondola kwambiri, ndipo pamwamba pake ndi yosalala komanso yokongola.Panthawi imodzimodziyo, ilinso ndi zinthu zosiyanasiyana zapamwamba zamakina, makamaka pokhudzana ndi ntchito yokonza.
(2) Makhalidwe a zitsulo zotentha zotentha: Pakugudubuza kotentha, chitsulocho chimakhala ndi pulasitiki yapamwamba komanso kukana kwapang'onopang'ono, kuchepetsa kwambiri kugwiritsa ntchito mphamvu zowonongeka kwazitsulo.Kugubuduza kotentha kumatha kusintha magwiridwe antchito a zitsulo ndi ma aloyi, ndiye kuti, kuphwanyidwa kwa mbewu zowoneka bwino m'malo oponyedwa, kuchiritsa ming'alu yayikulu, kuchepetsa kapena kuthetsa zolakwika zoponyera, kusintha mawonekedwe oponyedwa kukhala opunduka, ndikuwongolera kukonza. ntchito ya alloys.

3. Zofunikira pakukonza kwa awiriwa ndizosiyana
(1) Zofunikira pakukonza zitsulo zoziziritsa kuzizira: Chitsulo chozizira chozizira chimafunikira mphamvu yayikulu ya mphero, kuyendetsa bwino kwapang'onopang'ono, komanso kuwongolera kwapakatikati kuti athetse kuuma kwa ntchito panthawi yogubuduza, motero mtengo wake ndi wokwera.
(2) Zofunikira pakukonza chitsulo choyaka moto: Chitsulo choyaka moto ndi chosavuta kugudubuza ndipo chimakhala ndi magwiridwe antchito apamwamba.Kutentha kotentha kumaphatikizapo kutentha koyambira komanso kutentha komaliza.Kutentha koyambira kumatsimikiziridwa makamaka kutengera pafupifupi 80% ya kutentha kwa solidus mu chithunzi cha aloyi, pomwe kutentha kwapang'onopang'ono kumatsimikiziridwa potengera chithunzi cha aloyi, chomwe nthawi zambiri chimayendetsedwa pamwamba pa kutentha kwa alloy recrystallization.
