采用PAG水溶液对钢球进行淬火的工艺研究

Study on technology of quenching steel ball with PAG water solution

针对大钢球采用快速淬火油、Na_2CO_3水溶液及 PAG 水溶液淬火的工艺试验,说明尺寸较大的钢球采用快速淬火油、Na_2CO_3水溶液淬火的热处理性能指标均达不到要求,而采用 PAG 水溶液淬火能保证大钢球的热处理质量。

This test specifies that quenching steel ball of big size with fast quenching oil,or Na_2CO_3 water solution can not satisfy the requirement of heat treatment performance,But the heat treatment quality of big size steel ball can be ensured with PAG water solution.
