Zusammenfassung: | The invention discloses a medium-temperature ageing thermal treatment method for stainless steel and a vacuum furnace adopted by the medium-temperature ageing treatment method, and relates to the technical field of stainless steel thermal treatment. The original vacuum furnace equipment is modified, so that communication positions of an inert gas source, vacuum equipment and a vacuum container arechanged, i.e., the purpose of blocking water steam from entering a thermal treatment box is achieved by virtue of a way of changing an inert gas flow direction to match with a pumping action direction, and therefore, the purpose of solving the problem that medium-temperature ageing thermal treatment of a stainless steel product has oxidization discoloration is achieved.
本发明公开了一种不锈钢中温时效热处理方法及其真空炉,涉及不锈钢热处理技术领域,通过对原有的真空炉设备进行改造,改变惰性气体源和真空设备与真空容器的连通位置,即通过改变惰性气体流动方向和抽吸作用方向相配合的方式,达到阻隔水蒸气进入至热处理箱体内部的目的,进而达到解决不锈钢产品中温时效热处理发生氧化变色问题的目的。 |
