以前冷焊或热焊生铁,效果都不很好,不是强度不够,就是焊缝处硬度太高,不容易加工。1955年春,苏联专家耶洛什金同志,在鞍山钢铁公司提出在特殊熔剂夏盖下、用低碳钢焊条焊补生铁制件的办法。在专家亲自指导下,鞍山钢铁公司总机械师经过9个月的准备和试验,基本上获得成功。焊炼的强度高于生铁制件本体,而且容易切削加工。因此,凡是铁质机件(如钢锭模、减速箱、机架、机座等)无论在铸造过程中或是使用过程中产生气
Previously cold welding or hot welding pig iron, the effect is not very good, not strength is not enough, that is, the weld at the hardness is too high, not easy processing. In the spring of 1955, Comrade Elozulin of the Soviet Union, at Anshan Iron and Steel Company, proposed a method of welding pig-iron parts with low-carbon steel electrodes under a special flux, Xiagai. Under expert guidance, Anshan Iron and Steel Company chief mechanic basically achieved success after nine months of preparation and testing. The intensity of welding is higher than the body of pig iron parts, and it is easy to cut and process. Therefore, all the iron parts (such as ingot mold, gear box, rack, machine base, etc.) in the casting process or in the process of using gas
