目前我国轴承生产厂所采用的“GCr15轴承零件冷酸洗检查工艺”是沿用苏联40～50年代的工艺,工艺中使用了大量的CrO_3作为明化液。而我所几年前研究出的“9Cr18不锈钢轴承零件酸洗工艺”及“Cr4Mo4V高温钢轴承零件酸洗工艺”除使用CrO_3外,还加有适量的HF作为明化液。而CrO_3与HF都是极有害物质,严重污染环境及水源,危害人类健康,危害牲畜与农作物。为此,试验研究一种不含 CrO_3、HF的酸洗检查工艺,对于消除污染保护环境是一项具有实际价值的工作。 现将我们近年来对轴承零件原酸洗工艺中的有害成分CrO_3、HF的取代试验进行小结与商榷。
At present, China’s bearing factory used “GCr15 bearing cold pickling inspection process” is the use of the Soviet Union 40 to 50 years of technology, process used in a large number of CrO_3 as Ming liquid. And I studied a few years ago, “9Cr18 stainless steel bearing parts pickling process” and “Cr4Mo4V high temperature steel bearing parts pickling process” in addition to CrO_3, but also add an appropriate amount of HF as a clear liquid. The CrO_3 and HF are very harmful substances, seriously polluting the environment and water, endangering human health, endangering livestock and crops. Therefore, it is a practical work to study the pickling inspection process without CrO_3 and HF in order to eliminate the pollution and protect the environment. Now we in recent years, bearing parts of the original pickling process of harmful components CrO_3, HF substitution test summary and discussion.
