铜铬合金直接加铬熔炼和铸造

Melting and Casting of Cu Cr Alloys with Direct addition of Chromium

铬青铜系指含Ｃｒ０．４％～１．０％的铜基合金。是难于熔炼的合金，多以变形材料使用。经试验表明，采用中频感应电炉大气下熔炼，铬以纯金属加入，可获得性能优良的铸造Ｃｕ－Ｃｒ合金。

Chromium bearing bronze refers to a Cu based alloy containing 0.4%～1.0% Cr. Most of it is used as a wought material because it is difficult to be molten. The experiments indicate that a casting Cu Cr alloy with excellent properties can be obtained through melted by using an intermidiat frequency induction furnace in air with the addition of Cr as a pure metal.
