中温盐浴是热处理中广泛应用的加热介质。对于这类盐浴的脱氧,我厂在上海综合工业试验所协助下,会做了一些试验,兹将取得的一点经验介绍于下。 一、各种脱氧剂之试用结果 (1)硼砂(无水):硼砂加入盐浴后其作用如下: Na2B4O7=(NaBO2)2·B2O3 (NaBO2)2·B2O3+FeO=2NaBO2+Fe(BO2)2(
Medium temperature salt bath is widely used in heat treatment heating medium. For the deoxidation of this type of salt bath, I will do some experiments with the help of the Shanghai Integrated Industrial Experiment Institute. I will introduce the experience gained here. First, the results of a variety of deoxidizer test results (1) borax (anhydrous): borax salt bath after its role is as follows: Na2B4O7 = (NaBO2) 2 · B2O3 (NaBO2) 2 · B2O3 + FeO = 2NaBO2 + Fe (BO2) 2(
