加强热处理节能新技术的开发与应用是近年来热处理技术的发展方向,要求热处理设备在不断提高热处理产品质量的同时,尽量降低生产成本,以提高经济效益,下面扼要介绍近十年来国外控制气氛热处理设备的发展。 1.在热处理炉内直接安装气氛发生器,直到目前,由于国外采用碳氢化合物与空气的混合气为原料制备的吸热式气氛,在热处理中的应用仍占首位,气氛发生器的研究得到了较快发展。在热处理炉内直接安装气氛发生器,可使气氛制备和渗碳等工艺同时在一个炉内进行,与传统方法相比具有节能,省时和降低成本的突出优点。图1是西德伊普生公司1976年研究成功的一种装置,图2是日本中外炉公司1983年研制成
Heat treatment technology to enhance the development and application of heat treatment technology in recent years the development direction of the heat treatment equipment required to continuously improve the quality of heat treatment, while minimizing production costs, in order to improve economic efficiency, the following briefly describes the past decade the control atmosphere heat treatment Equipment development. 1. In the heat treatment furnace directly installed atmosphere generator, until now, due to foreign hydrocarbon and air mixture as raw material prepared endothermic atmosphere, the application of heat treatment is still the first place, the study of the atmosphere generator Rapid development. Direct installation of the atmosphere generator in the heat treatment furnace enables atmosphere preparation and carburization to be carried out in one furnace at the same time. Compared with the conventional method, the invention has the advantages of energy saving, time saving and cost reduction. Figure 1 is a device developed by West Germany Yipson Co., Ltd. in 1976. Figure 2 shows the Japanese and foreign furnace companies developed in 1983
