摘    要:采用(VAR)技术熔炼制备钛合金铸锭,为了提高铸锭质量,对原料纯净度、电极制备技术、熔炼工艺参数等方面进行控制与改进,减少了O、N、C、H、Si等杂质含量,保证了钛合金铸锭成分与组织的均匀性。经工业化生产试验最终使得(VAR)炉能够制备出符合标准要求的高纯度钛合金铸锭。

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.
