摘要
Abstract
During VAR smelting of titanium alloy ingots,feeding process system shall be adopted at the end of smelting,so as to reduce the loss rate of ingot riser and improve the yield.In the actual production process,the loss rate of titanium alloy ingot riser is affected by various factors.There is a large difference between each ingot,and the fluctuation range is large,resulting in serious losses.In order to analyze the influencing factors of the difference in the riser loss rate of titanium alloy ingots,the Minitab statistical software was used to conduct the research by the method of multi factor variance analysis.The significant influencing factors,such as the shift of smelting workers,the shift of feeding time,the flaw detection operator,operation stability during feeding period,and whether the feeding process was frequently shorted out,were found out,and the insignificant factor interaction was eliminated.According to the significant factors,the corresponding improvement measures were formulated,which effectively reduced the riser loss rate of titanium alloy ingots and the difference between ingots,and increased the product yield.关键词
