介绍了真空电子束区熔炉技术性能、区熔原理、设备结构及特点。该设备是国内第一台国产化的电子束区熔炉,能够对最大尺寸为φ30mm×1000mm的难熔金属及其合金棒料进行悬浮区域熔炼提纯,而且可以进行难熔金属及其合金单晶的制备工艺。该设备的研制成功,对我国难熔金属区域熔炼提纯及单晶制备技术的研究和生产具有重要的现实意义。
The technical performance, zone melting principle, equipment structure and characteristics of vacuum electron beam zone furnace are introduced. This equipment is the first domestically produced electron beam zone furnace in China. It can smelt and refine the refractory metal and its alloy bar with the largest size of φ30mm × 1000mm, and can also carry out melting and refining of the refractory metal and its alloy single crystal Preparation Process. The successful development of this equipment is of great practical significance for the research and production of smelting and purification of refractory metal in our country and the preparation technology of single crystal.
