我厂在轮胎式推土机及7～9米~3液压自行式铲运机的半轴热处理中,试用了氯化钙水溶性淬火介质,使半轴淬火硬度达到图纸要求,效果良好。现将氯化钙水溶淬火介质的配制、试验、使用情况等介绍如下。一、配制及淬火试验氯化钙水溶性淬火介质系南京汽车制造厂、镇江农业机械学院等单位共同研制的一种新的淬火介质。它的冷却曲线及特性见图1。由图1可见,灼热零件淬入该介质后,在极短
I plant in the wheel-type bulldozers and 7 ~ 9 m ~ 3 hydraulic self-propelled scraper semi-axis heat treatment, the trial of calcium chloride water-soluble quenching medium, the hardness of the semi-shaft quenching to meet the drawings, the effect is good. Now calcium chloride water quenching medium preparation, testing, use, etc. are as follows. First, the preparation and quenching test Calcium chloride water-soluble quenching medium Department of Nanjing Automobile Factory, Zhenjiang Agricultural Machinery Institute jointly developed a new quenching medium. Its cooling curve and characteristics shown in Figure 1. Can be seen from Figure 1, hot parts quenched into the medium, very short
