钛及钛合金真空熔炼装备的发展现状与未来趋势OA

The titanium industry is accelerating toward high-performance and high-value-added development against the backdrop of growing demand in aerospace,defense,and high-end civilian manufacturing.Vacuum melting equipment has become a key foundational technology that constrains the quality of titanium and titanium alloy materials as well as industrial upgrading.This paper systematically analyzes the development status and technological evolution of vacuum melting equipment for titanium and its alloys,considering global and Chinese titanium industry applications.The work focuses on three mainstream technologies:vacuum arc remelting(VAR),electron beam cold hearth melting(EBCHM),and plasma arc cold hearth melting(PACHM),highlighting their process principles,equipment characteristics,and engineering limitations.Key technical challenges are identified in areas such as composition segregation control in large ingots,alloy element volatilization,process stability under high vacuum,and energy efficiency.Based on this analysis,the paper suggests that future vacuum melting equipment for titanium and titanium alloys will evolve toward flexible and modular processes,intelligent control based on digital twins and artificial intelligence,and green recycling manufacturing aligned with low-carbon objectives,providing a reference for independent development and technological upgrading of titanium industry equipment in China.
