Water-soluble quenching fluid roller type net belt furnace is not only environmentally friendly but also anticorrosive, so it is a good choice for continuous furnace to adopt single liquid quenching. But it still has some kind of limitation, for instance to 40Cr, 45Mn wait for steel, the proportion of deformation and craze still cannot be underestimated.
I used U - con roller type mesh belt quenching furnace quenching liquid (is imported products, the price also does not poor), 45 steel workpiece is wrench and socket, heating temperature and quenching temperature is not high, but often face a 5% had a quenching crack, may be the material of manganese content in the ceiling, as for the proportion of some workpiece thickness disparity cracking is bigger. 40Cr is even more nervous, almost afraid to have this idea. As for the concentration of the configuration is made according to the standard requirements, and the quenched samples have been sent to the quenching fluid supplier for solutions, which the supplier has not much to do.
