Embodiment Construction
[0013] figure 1 and figure 2 Shown, a kind of manufacturing method of the pressure casting product that alloy liner is housed. The centrifugal pump casing mold with alloy lining is a hollow composite mold. The centrifugal pump casing hollow composite mold is composed of a centrifugal pump casing hollow sub-mold. The centrifugal pump casing hollow sub-mold is made of steel plate stamping and welding. It is stamped and welded with stainless steel plate, brass plate or aluminum alloy plate. Melt steel slag powder or glass powder with an oxyacetylene flame and spray it on the inner surface of the hollow sub-mold of the centrifugal pump casing that is in contact with molten steel during pressure casting, or use 'water glass' to blend steel slag powder or glass powder, and then coat it on the mold during pressure casting The inner surface of the hollow sub-mold of the centrifugal pump casing in contact with the molten steel, and then heated and melted with oxyacetylene flame to m...
