我厂过去是用固体渗碳法,把工件和渗碳剂(牛骨粉,粟炭,食盐混合)装在铸铁箱内,放在可锻铸铁退火炉内加热,烧到900℃左右,在炉内慢冷,另外再进行淬火和回火。这样,生产周期需要三天左右。以后改用反射炉加热还是要在一天左右,并且在装炉量大的条件下,工件少了不合算,等待上道工序必然 In the past, our factory used the solid carburizing method to put the workpiece and carburizing agent (bovine bone powder, charcoal, salt mixed) in a cast iron box and put it in the malleable iron annealing furnace to heat it to about 900 ℃ and slowly in the furnace Cold, another quenching and tempering. In this way, the production cycle takes about three days. After the switch to the heating furnace or refuse to be about a day, and in a large amount of loading conditions, the workpiece less uneconomical, waiting on the road process inevitable
