连续真空热处理炉的开发六十年代初,真空热处理主要用于宇航工业、飞机制造业等特殊金属制品的热处理,重点是提高零件机械性能,使零件的热处理质量达到十分理想状态。到了六十年代后半期,无公害问题的提出以及由于该炉操作维护简单等特点,其应用范围日益扩大,已广泛用于工具 Continuous vacuum heat treatment furnace development The early sixties, vacuum heat treatment is mainly used for aerospace industry, aircraft manufacturing and other special heat treatment of metal products, the focus is to improve the mechanical properties of parts, so that parts of the heat treatment to achieve a very good quality state. By the second half of the sixties, the issue of pollution-free and because of the furnace operation and maintenance features such as simple, and its expanding range of applications, has been widely used in tools
