一种高压液态或超临界态淬火的装置
摘要：
本发明涉及一种高压液态或超临界态淬火的装置，包括：工作室，内部设有加热设备和冷却设备，并连接有真空泵组；储存罐，设有液态二氧化碳供给口，并连接工作室的液态二氧化碳入口；缓存罐，通过增压回路分别连接工作室和储存罐，还通过循环回路分别连接工作室和储存罐；气体增压机，设于缓存罐的出气口处；第一压力测量器，设于工作室上；温度控制器，设于工作室上，分别连接加热设备和冷却设备。与现有技术相比，本发明具实现了真空液态或超临界态淬火，不仅满足大工件的淬火需求，又能达到高压气淬的效果，而且还是干净、清洁的热处理，无废气、废水污染，节能、环保的热处理。
摘要（英）：

Disclosed are a high-pressure liquid-state or supercritical-state quenching apparatus, comprising a working chamber, a heating device, a cooling device, a vacuum pump set, a storage tank, a buffer tank, a gas booster, a first pressure gauge, and a temperature controller. According to the Invention, vacuum liquid-state or supercritical-state quenching is implemented, which satisfies a quenching requirement of a large workpiece, and can also achieve an effect of high-pressure gas quenching. In addition, clean heat treatment is implemented, which avoids waste gas and waste water pollution, and is energy-saving and environmentally-friendly heat treatment.
