本文研究了几种添加剂(Na_2C上O_3+C,K_2CO_3+C,CaCO_3+C,S,CaO+C,Ca)对铜铅合金凝固组织的影响,在实验工作中采用了三种实验方法(普通铸造法、颗粒感应加热熔,铸法和液淬法)。研究结果表明,几种添加剂都能有效地细化组织,其中少量 S,钙和钙的化合物使铅相呈点、块状分布,K_2CO_3C 和 Na_2CO_3C 使铅相形态呈半网状分布 In this paper, the effects of several additives (O 3 + C, K 2 CO 3 + C, CaCO 3 + C, S, CaO + C, Ca) on the solidification structure of Cu-Pb alloy were studied. Three experimental methods Casting method, grain induction heating melting, casting method and liquid quenching method). The results show that several additives can effectively refine the microstructure. A small amount of S, Ca and Ca compounds make the lead phase point and block distribution, K_2CO_3C and Na_2CO_3C make the lead phase form a half-mesh distribution
