真空炉已被用于钢、有色金属和高温合金的热处理。然而,气压仅达1.5或2巴的正常气压淬火设备不适用象 M2这样的厚大截面的高速工具钢的淬火,因为会导致不希望有的碳化物的析出且达不到最大可淬硬度。Rockpord,IL,Ipsen 工业公司设计和制造的一种 VTC 型高压超冷真空炉对这些厚截面工具钢进行真空处理,可充分挖掘其硬度潜力。该炉子的炉身实际上为高压容器,其内装有一台大功率低噪音透平鼓风机和一个大面积低阻力的热交换器。它与外露式鼓风
Vacuum furnace has been used for heat treatment of steel, non-ferrous metals and superalloys. However, normal atmospheric pressure quenching equipment with gas pressures of only 1.5 or 2 bar are not suitable for the quenching of high-speed tool steels with large sections such as M2 because of the undesired precipitation of carbides and the lack of maximum hardenability. Rockpord, IL, a VTC-type, supercritical vacuum furnace designed and built by Ipsen Industries, vacuum-treats these heavy-gauge tool steels to exploit their hardness potential. The hearth of the furnace is actually a high-pressure vessel, which houses a high-power, low-noise turbine blower and a large area low-drag heat exchanger. It’s exposed blast
