合成淬火剂是国内已广泛应用的有机淬火溶液。其主要成分是水溶性高分子化合物聚乙烯醇。合成淬火剂具有下列特性:(1)良好的冷却性能;(2)不燃烧,无火灾的危险,也不致因烟雾污染环境;(3)可改变浓度和使用温度,获得适用于各种钢种的冷却性能。因此合成淬火剂的应用范围不断扩大。现在除了应用于高、中频淬火外,也应用于一般热处理淬火,取代双液淬火工艺。但往往由于使用不当,而造成零件出现淬火裂纹,从而阻碍了
Synthetic quenching agent is widely used in domestic organic quenching solution. Its main component is a water-soluble polymer polyvinyl alcohol. Synthetic quenching agent has the following characteristics: (1) good cooling performance; (2) does not burn, no risk of fire, nor smog caused by the environment; (3) can change the concentration and temperature, access to a variety of steel Cooling performance. Therefore, the scope of application of synthetic quenching agent continues to expand. Now used in addition to high and medium frequency quenching, but also used in general heat treatment quench, instead of two-liquid quenching process. But often due to improper use, which caused the parts appear quenched cracks, which hindered
