The smelting of the vacuum consumable furnace relies on the heat energy of the arc to melt the metal electrode under vacuum or protective atmosphere conditions, and then remelts it into an ingot in the crucible. During the electrode melting process, the molten metal is heated to a high temperature through the arc zone. Under vacuum conditions, gases and impurities in the metal are further removed, thereby improving the quality of the metal. During vacuum consumable melting, the melting process has a direct impact on the surface quality of titanium alloy titanium ingots.
The more serious the surface defects of titanium alloy titanium ingot, the larger the amount of swarf and cuttings, so the quality of the surface has a great influence on the materialization rate of titanium alloy titanium ingot. Relevant professional and technical personnel of the vacuum self-consumption melting process parameters on the surface quality of titanium alloy ingots to study the law, through the actual production and theoretical analysis of the method to study the melting process of the surface of different defects in the process of the reasons for the emergence of the preventive measures, and the development of the melting process, the results proved that the development of the process is reasonable, titanium alloy titanium ingots to improve the quality of the surface, the amount of ingot skimming is small, the rate of the product into the material is high. The surface quality of titanium alloy ingot is improved.
