有些零件淬火后需在油炉中进行低温回火,然后经除油处理转入下道工序。现在生产中大多采用沸腾碱水除油。这种方法无疑要消耗一部分能源和化工材料,而且操作也比较麻烦,为此,我厂热处理工人在生产中摸索出一种以冷水除去热处理零件油污的方法,在实际生产中取得了较好效果。例如,45钢拖拉机齿轮感应淬火和低温回火后,要求齿表面硬度50～58HRC,无裂纹,无氧化皮及脏物。热处理后的除油工艺,原用
Some parts after quenching in the oil furnace for low temperature tempering, and then removed by the oil into the next process. Now most of the production of boiling alkaline degreasing. This method will undoubtedly consume part of the energy and chemical materials, and the operation is too much trouble, to this end, I plant heat treatment workers in the production to explore a way to remove oil heat treatment parts of cold oil in the actual production has achieved good results . For example, 45 steel tractor gear induction hardening and low temperature tempering, the tooth surface hardness requirements of 50 ~ 58HRC, no cracks, no oxide and dirt. Heat treatment after the degreasing process, the original use
