Titanium is more and more widely used in industrial production, aerospace, national defense and military industry as well as in daily life, so the requirements for titanium and titanium alloy c and its properties are more and more high. And raw materials of titanium alloy smelting is undoubtedly the most important a key ring, the smelting quality directly affects the subsequent processing performance of the finished product meets the product requirements, so as to promote the development of the titanium alloy smelting technology, including development of new technologies, such as electron beam, plasma cooling bed furnace, to improve the metallurgical quality and the mechanical properties of titanium alloy ingot has created good conditions and basis.
Titanium alloy melting methods: vacuum consumptive electric arc furnace melting method (VAR method), non-consumptive vacuum arc furnace melting method (NC method), cold hearth melting method (CHM method), cold pot melting method (CCM method), electroslag melting method (ESR method).
Today's aerospace technology puts forward more stringent quality requirements for titanium and titanium alloy ingot casting. In addition to strictly controlling the quality of the production process, it is necessary to adopt multiple smelting processes, at least one of which is carried out in vacuum, to obtain high-quality ingots. This requires comprehensive utilization of the characteristics of each smelting method to achieve the physical metallurgical process of titanium and titanium alloy, so as to obtain excellent performance, continuous reproduction of high-quality titanium and titanium alloy ingot.
