本文介绍一种既方便易行,又具备多种功能的制备可控气氛热处理的气源设备——JCL型甲醇低温催化裂解机。由于采用了高活性、高选择性的TC-502型裂解催化剂,可使甲醇在300℃的低温下受控裂解,得到的气氛碳势较高,900℃下可达1.0%,而且能按需要在0.1～1.0%范围内准确调节。因而它具备以下功能:多种碳钢和合金钢的光亮淬火和退火保护、渗碳、软氮化、复碳,以及低碳钢的去应力退火等热处理工艺都能发挥很好的作用。
This article describes a convenient and easy to operate, but also has a variety of functions for the preparation of controlled atmosphere heat treatment gas source equipment - JCL methanol low temperature catalytic cracking machine. Due to the high activity and high selectivity of the TC-502 cracking catalyst, methanol can be controlled pyrolysis at a low temperature of 300 ° C, resulting in a higher carbon potential of the atmosphere up to 1.0% at 900 ° C and as required In the range of 0.1 ~ 1.0% accurate adjustment. Therefore, it has the following functions: Bright quenching and annealing protection of a variety of carbon steel and alloy steel, carburizing, nitrocarburizing, double carbon, and stress relief annealing of mild steel can all play a very good role.
