可控制气氛用于热处理是门新技术,其基本原则是在高温及触媒条件下,使一定比例的丙烷与空气混合反应而成的一种还原性气氛,这种气氛能使钢铁在加热时既不脱碳,又不氧化(特殊情况还能渗碳),达到光亮淬火的要求.本设备采用无马费式的加热炉,这是一种新的尝试,为国家节约了大量贵重金属——镍,但目前所用的抗渗碳耐火砖及防止电热体抗渗碳的釉层还需摸索研究进一步提高. Controllable atmosphere for heat treatment is a new technology, the basic principle is under high temperature and catalyst conditions, make a certain proportion of propane and air mixed reaction of a reducing atmosphere, this atmosphere enables the steel when heated both No decarburization, no oxidation (special circumstances carburizing), to achieve the requirements of bright quenching.This equipment uses a horse-style furnace, which is a new attempt to save the country a large number of precious metals - Nickel, but the current use of anti-carburizing refractory brick and anti-carburizing glaze to prevent further study.
