大型立式LZT-150真空退火炉是国内首台大型高温真空炉，为国产大型真空热处理设备的开发研制填补了空白。其主要技术指标都达到了我国军标及美国军用标准要求，其技术水平达到80年代国际水平。该炉主要用于马氏体不锈钢1Gr13和沉淀硬化型不锈钢17－4PH等材料的大型零部件整体退
Large-scale vertical LZT-150 vacuum annealing furnace is the first large-scale high-temperature vacuum furnace for domestic large-scale vacuum heat treatment equipment development and development to fill the gap. Its main technical indicators have reached the military standard of China and the United States military standards, its technical level reached the international standards of the 1980s. The furnace is mainly used for martensitic stainless steel 1Gr13 and precipitation hardened stainless steel 17-4PH and other large parts of the overall material back
