为了解决零件的变形问题,我厂热处理车间,曾在一个时期中,使用熔融的苛性鹼作淬火剂(其成份是35％氢氧化钠NaOH,65％氢氧化钾KOH)。这种淬火剂的冷却能力很强,淬火后的工件变形也很小,同时还可以获得光潔的表面,免去喷砂处理。由于使用了这种冷却剂,解决了不少关键问题。但是在使用期间,我们发现这样淬火剂的损耗很大,同时氢氧化钾价格又贵,大大的提高了零件
In order to solve the problem of deformation of parts, our factory heat treatment workshop, in a period of time, the use of molten caustic as a quenching agent (its composition is 35% sodium hydroxide NaOH, 65% potassium hydroxide KOH). This quenching agent cooling ability, after quenching the deformation of the workpiece is also small, but also get a smooth surface, eliminating the sandblasting. Due to the use of this coolant, many key problems have been solved. However, during use, we found that such quenching agent loss, while the price of potassium and expensive, greatly increased the parts
