摘要
采用熔点比铜合金熔点低100～200℃的MgF2-CaF2渣系重熔B30铜合金,熔化速率(kg/h)控制在(1～1.3)×结晶器直径(mm),有利于改善电渣锭的表面质量,提高铜合金纯净度和电渣锭致密度,改善锻造性能。
MgF2-CaF2 Slag with melting point 100 -200℃ lower than that of copper alloy has been used to remeh B30 copper alloy. The melting rate （kg/h） is controlled within the value of 1 - 1.3 muhipying by the diameter of mould. It tends to improve the surface quality of electroslag ingots and forging property, increase the purity of copper alloy and the density of electroslag ingots.
