研究了利用真空热处理工艺提高机械零部件工作性能和可靠性的可能性 ,重点介绍了波兰一家工厂推出的最新一代的真空炉。在该炉中工件加热后可以用高压 0 .6 MPa的惰性气体气流进行淬火。气体的循环是靠一台涡轮式空气压缩机 ,将气体由上向下通过一个气流分布装置喷向工件 ;工件 The possibility of using the vacuum heat treatment process to improve the workability and reliability of mechanical parts was studied, with an emphasis on the latest generation of vacuum furnaces from a factory in Poland. In the furnace after the workpiece can be heated with high pressure 0. 6 MPa inert gas flow quenching. Gas circulation is by a turbo air compressor, the gas from the top down through a gas distribution device to the workpiece; workpiece
