本发生装置,是将空气与原料气混合后,通过镍基催化剂的高温反应罐,经一系列物理——化学变化制成几乎不含氧化性气氛(CO_2、H_2O、O_2)主要是还原性气氛(CO、H_2)与惰性气氛(N_2)组成的吸热式可控气氛。 这种还原性气氛与惰性气氛,可以在进行渗碳及氮碳共渗热处理时,作为稀释气氛。在不同的热处理要求下,可以通过控制该气氛的露点(亦即控制气氛中水蒸气的含量),来控
The present invention is a device which is composed of a series of physico-chemical changes made of a mixture of air and raw material gas and passing through a high-temperature reaction tank of a nickel-based catalyst, wherein the substantially oxygen-free atmosphere (CO 2, H 2 O, O 2) is mainly a reducing atmosphere (CO, H_2) and an inert atmosphere (N_2) consisting of endothermal controllable atmosphere. Such a reducing atmosphere and an inert atmosphere can be used as a diluting atmosphere when performing carburizing and nitrocarburizing heat treatment. In different heat treatment requirements, you can control the dew point of the atmosphere (that is, control the amount of water vapor in the atmosphere), to control
