Ⅰ绪言由于在设计和生产中采用了新方法以及对环境保护提出了新的要求,因而推动了热处理工艺的发展。但目前的热处理设备却不能满足工艺发展的需要。在文中,作者首先介绍的主要是成品或半成品的气氛热处理或真空热处理工艺。然后综述了有关气氛热处理的设备(特别是新型的推杆式炉),氧势测定系统,碳氢化合物直接渗碳(用氮作载体),真空炉里气体淬火和真空铝焊接等方 I. INTRODUCTION The development of heat treatment processes is being promoted by the introduction of new methods in design and production and new requirements for the protection of the environment. However, the current heat treatment equipment can not meet the needs of process development. In this paper, the author mainly introduces the atmosphere heat treatment or vacuum heat treatment process of finished or semi-finished products. Then the equipment for atmosphere heat treatment (especially the new push rod furnace), the oxygen potential measurement system, the direct carburizing of hydrocarbons (using nitrogen as carrier), gas quenching in vacuum furnace and vacuum aluminum welding are reviewed
