众所周知,在密封箱式炉中可进行渗碳、碳氮共渗、光亮淬火等多种热处理工艺操作,所以又叫多用炉。由于炉内气氛能调节控制并可在保护气氛中冷却淬火,所以能获得好的表面处理质量并能提高零件的使用寿命。在多用炉中采用液体为原料的滴注式可控气氛热处理,同带有气体发生炉的可控气氛热处理相比,由于不需要发生炉,故投资和使用费用低,而且操作维护也方便。实践证明,原带有发生炉式的多用炉只要稍加改装,便能进行滴注式可控气氛热处理操作。因此对于中、小批生产的工厂和液化气供应较困难
As we all know, in a sealed box furnace carburizing, carbonitriding, bright quenching and other heat treatment process operation, it is also called multi-purpose furnace. Since the atmosphere in the furnace can be controlled and cooled and quenched in a protective atmosphere, it is possible to obtain a good surface finish quality and improve the service life of the part. Compared with the controllable atmosphere heat treatment with gas furnace, the drip-type controlled atmosphere heat treatment using liquid as the raw material in the multi-purpose furnace has lower investment and use cost and convenient operation and maintenance compared with the controllable atmosphere heat treatment with the gas furnace. Practice has proved that the original furnace with a multi-purpose furnace as long as a slight modification, can be dripped controlled atmosphere heat treatment operation. Therefore, for medium and small batch production of liquefied gas supply plants and more difficult
