摘　　要：依据Pb—sb合金二元相图，确定了铅锑合金87％Pb-13％Sb的质量配比，分析了铅锑合金的熔炼工艺特点，制定了熔制铅锑中间合金以及二次重熔法生产工艺，将其熔点控制在250—280℃，节约了熔炼工艺成本。通过选择合理浇注位置以及采用挂锡、预热、强制冷却等措施，达到了控制索节连接质量的目的。Based on Pb - Sb binary phase diagrams, the smelting processing features of lead - antimony alloys was analyzed and the compositions was defined as 87% Pb - 13% Sb in mass ratio. The processing parameters of the lead- antimony master alloy smelting and the re -smelting was determined and the melting point was controlled ranging 250 - 280℃ so the cost of smelting was reduced. Through the design of the proper casting systems, prehea- ting , forced cooling, tin coatings , the joining quality of socket was improved.
