Quenchant for mesh belt furnace

Water soluble quenchant is not only environmentally friendly but also anticorrosive. It is a good choice to use single quenchant in continuous furnace. However, there are some limitations, such as for 40Cr, 45MN and other steels, the ratio of deformation and cracking should not be underestimated.

The u-con quenchant I used (imported product, the price is not cheap), the workpieces are 45 steel wrenches and sockets, the heating temperature and quenching temperature are not high, but there are often about 5% of quenching cracks, probably because the manganese content of this batch of materials is in the upper limit, to some workpieces with great thickness differences, the proportion of cracking is even greater. 40Cr is even more fearful, almost dare not have this thought. As for the concentration of the configuration, it is done according to the standard requirements, and the cracked samples have been sent to the quenchant supplier to seek solutions, and the supplier has not much way to solve this.
