This article has investigated the principle and method of smelting CuMn35 master alloy by fusion alloying. And some questions about deoxidation and removal of hydrogen has been discussed. We have found the best process conditions after a series of orthogonal experiments and obtained uniform components by chilling technique. Elsewhere, we use carbon and cryolite as covering agent and refining agent to reduce oxide inclusion greatly and improve the surface texture and the yield of copper and manganese, attained 99.99% and 99.31% respectively. The results of the experiment show that the process is advisable.
