Abstract:The vacuum arc remelting technology is used for preparing the titanium ingot. In order to improve the ingot quality, the purity of raw material, the preparative technique of electrode and the melting process parameters were strictly controlled and improved. The contents of impurity elements such as O, N, C, H and Si are reduced and the titanium ingots have a good homogeneity on chemical composition and microstructure. After having a industrial test, it is found that the VAR preparative technique can meet the standard requirement of high purity titanium ingot.
