摘要
由于材料淬透性偏低,我公司093主轴渗碳淬火后,无论AICHELIN还是Ipsen多用炉,都出现了心部硬度低的情况。为解决这一问题,我公司技术工作人员进行了一系列的工艺调整及工艺试验。通过调整油淬淬火温度、淬火油温度、淬火油搅拌速度、油槽添加新淬火油、相对降低整炉装炉量,多种措施综合调整淬火冷却介质的冷却能力,并对多组试验数据及工艺参数进行分析,最终确定了最佳工艺,即:多用炉油淬,淬火温度900℃,油温30℃,搅拌速度1500r/min,油槽添加新淬火油3桶,整炉装炉量74根。工艺参数确定后,重汽093主轴心部硬度能够达标。
Due to the low hardenability of the material, our company 093 spindle carburizing and quenching, whether AICHELIN or Ipsen multi-purpose furnace, there is a low hardness of the heart. In order to solve this problem, our technical staff carried out a series of process adjustment and process test. By adjusting the oil quenching oil quenching temperature, quenching temperature, quenching oil,stirring speed, adding new quenching oil tank, the relatively lower furnace furnace charging quantity, various measures, a comprehensive adjustment of cooling capacity of quenching cooling medium and the multiple sets of test data and the process parameters were analyzed,and finally the optimum process was determined, i.e., the multi-purpose furnace oil quenching, quenching temperature 900℃, the oil temperature 30℃, stirring speed 1500 r/min, adding new quenching 3 barrels of oil tank, the whole furnace furnace charging quantity 74.After the process parameters are determined, the core hardness of the main shaft of sinotruk 093 can reach the standard.
