Abstract

Abstract

Metallurgical defects such as segregation and inclusion will occur when vacuum arc remelting (VAR) is used to melt TB9 titanium alloy. MeltFlow-VAR simulation software was used to simulate the primary melting process of TB9 titanium alloy VAR, and the influence of melting current and arc stabilization type on the melting process was investigated. By analyzing the element distribution, molten pool depth and impurity throwing path of ingot under different technological conditions, the optimal primary melting process was obtained. Using the original process and optimized process parameters, the whole process of tertiary VAR melting process of TB9 titanium alloy was simulated, and the element distribution of tertiary ingots was obtained. The results show that there is a “genetic” phenomenon in the process of multiple melting. After optimizing the original process of primary melting in this factory, the composition uniformity of tertiary finished ingots can be significantly improved.
