Chipata valavu zopangira zosapanga dzimbiri mbale kuwotcherera ndodo

Chipata valavu zopangira zitsulo zosapanga dzimbiri mbale kuwotcherera ndodo Izi muyezo zosapanga dzimbiri mbale kuwotcherera ndodo mfundo gulu, mfundo luso, njira kuyezetsa ndi miyezo kuyezetsa ndi zina zokhudzana. Muyezo uwu umagwira ntchito ku electrode yachitsulo chosapanga dzimbiri pakuwotcherera kwa arc. Zitsulo zotere zokhala ndi ma elekitirodi ziyenera kukhala ndi chromium yopitilira 10.50% ndi chitsulo chochulukirapo kuposa chinthu chilichonse. Malinga ndi zikuchokera anasakaniza zitsulo, mtundu wa kuwotcherera pachimake, kuwotcherera udindo ndi mtundu wa kuwotcherera panopa, ndodo kuwotcherera sayenera kukhala ndi chilema monga ming'alu, thovu, zotsalira ndi kugwa kuti zoipa kuwotcherera khalidwe, monga taonera Table 1 ndi Table. 2. 1. Lingaliro lamutu ndi gawo la ntchito Izi mulingo wosapanga dzimbiri wowotcherera mbale wowotcherera, miyeso yaukadaulo, njira zoyesera ndi miyezo yoyesera ndi zidziwitso zina zokhudzana nazo. Muyezo uwu umagwira ntchito ku electrode yachitsulo chosapanga dzimbiri pakuwotcherera kwa arc. Zitsulo zotere zokhala ndi ma elekitirodi ziyenera kukhala ndi chromium yopitilira 10.50% ndi chitsulo chochulukirapo kuposa chinthu chilichonse. 2 Reference Standards GB223.1 ~ 223.70 Njira zowunikira zitsulo ndi ma aluminiyamu aloyi GB1954 - Kuyeza kwa microstructure zomwe zili mu kuwotcherera kwa chrome-nickel low alloy steel GB2652 Tensile test njira yowotcherera ndi kuyika zitsulo GB 4334.5 Mayeso azitsulo zosapanga dzimbiri - Mayeso osapanga dzimbiri njira sodium thiosulfate hydrochloride 3 Mtundu ndi specifications gulu 3.1 Mtundu ndi mfundo za ndodo kuwotcherera adzagawidwa malinga zikuchokera anasakaniza zitsulo, mtundu wa kuwotcherera pachimake, malo kuwotcherera ndi mtundu wa kuwotcherera panopa. 3.2 Njira yokonzekera mafotokozedwe a chitsanzo Chilembo "E" chimasonyeza electrode, ndipo nambala pambuyo pa "E" ikuyimira chiwerengero cha chigawo chachitsulo chosungunuka.
