前言我厂根据照相机产品的结构特点及零件的性能和工艺要求,于1977年自制了一台多功能化学热处理炉。该炉具有功率小、加热快、炉温均匀、节电、安全、无公害等特点;炉上设有固、液、气体原料输入装置,可进行气体氮碳共渗和多元共渗等表面强化处理。几年来的实践证明:应用该设备对提高产品质量可获得良好的经济效果。
Preface Our factory made a multifunctional chemical heat treatment furnace in 1977 according to the structural characteristics of the camera products and the performance and technical requirements of the parts. The furnace has the characteristics of small power, quick heating, uniform temperature, energy saving, safety and pollution-free. The furnace is provided with a solid, liquid and gas raw material input device for surface strengthening such as gas nitrocarburizing and multicomponent permeation deal with. Years of practice has proved that: the application of the device to improve product quality can obtain good economic results.
