引言第二机械工业部曾在55年提出了以植物油代替锭子油淬火的课题。这本来不是一个十分合理的措施,因为植物油多半是食用油料,一般国家都是尽量想办法用矿物油代替植物油。因此,这一研究工作实际意义并不太大。但作者认为通过实验、比较若干种植物油的淬火冷却能力,在目前各厂矿大量使用植物油淬火的情况下,仍不失为一个可供参考的资料。
Introduction In the past 55 years, Ministry of Machinery Industry has put forward the subject of vegetable oil quenching instead of spindle oil. This was not a very reasonable measure because most vegetable oils are edible oils. In general, countries try to find ways to substitute mineral oils instead of vegetable oils. Therefore, this research work is not very practical. However, the author believes that through experiments, the ability to compare the quench cooling capacity of several kinds of vegetable oils is still a reference for the large amount of vegetable oil quenching used in various factories and mines.
