图1弹性套,材质65Mn,曾在RJX-30-9箱式电炉中加热淬火。加热时浸涂硼砂酒精溶液(94%酒精+6%硼砂)保护,淬火效果不好。后改用盐浴炉加热淬火,但由于弹性套的有效厚度为4mm,最薄处仅1.5mm,从加热炉取出淬入油中之前,因为温降太大影响油淬效果,如果提高加热温度,65Mn材料有较敏感的过热倾向,易产生过热。所以处理的弹性套在使用过程中,有的弹性达不到要
Figure 1 elastic sleeve, material 65Mn, was quenched in the RJX-30-9 box electric furnace. Baptist when heated borax alcohol solution (94% alcohol + 6% borax) protection, quenching effect is not good. After the switch to salt bath heating quenching, but the effective thickness of the elastic sleeve is 4mm, the thinnest at only 1.5mm, removed from the heating furnace quenching oil before, because the temperature drop is too large affect the oil quenching effect, if you increase the heating temperature , 65Mn material has a more sensitive overheating tendency, easy to produce overheating. Therefore, the elastic handle in the process of using, some of the flexibility to reach
