淬火是热处理工艺中最重要而又最容易发生质量事故的环节。淬火加热用盐的品质对保证零件的淬火质量尤为关键。因此,必须对原材料盐类中有害的氧化性酸盐进行分析鉴定。然而,在定量分析前,则需要对其进行定性分析试验,从而有针对性地进行定量分析,以便提高分析的准确性和分析速度,有效的保证工件淬 Quenching is the most important heat treatment process and the most prone to quality accidents link. Quenching the quality of the salt used to ensure the quality of quenching parts is particularly crucial. Therefore, the identification of harmful oxidizing salts in raw salt must be performed. However, before the quantitative analysis, you need to carry out qualitative analysis of the test, so as to conduct quantitative analysis, in order to improve the accuracy and speed of analysis, effectively guarantee the workpiece quenching
