我厂多年来在中小铸铁件、球墨铸铁件、高硅耐蚀铸铁件及有色金属件铸造中大量应用随形压边浇冒口。由于随形压边浇冒口既是浇口又是冒口,是随着不同铸件边缘的形状开设较长而狭小的缝隙内浇口,故挡渣能力强;由于金属液先通过冒口再进入铸型, Over the years I plant in small cast iron pieces, ductile iron pieces, high-silicon corrosion-resistant cast iron and non-ferrous metal castings in a large number of applications with the pressure side edge Riser. Since the pouring riser is both a gate and a riser along with a pressing edge, a long and small gap gate is provided along with the shape of the edge of the different castings so that the slag blocking ability is strong. Since the molten metal re-enters through the riser first mold,
