The Special Process of Material of Impact Crushers Liner

Considering the service life of the impact crushers, YIFAN has special treatment in the process of the material of the Impact Crushers liner. Before the high-manganese steel material is made into the liner of the impact crushers, it needs to go through water toughing. In this process, the heating rate is one of the most important reasons to affect the final quality of the materials.

During the Impact Crushers Liner heating process, high manganese occurs the eutectoid transformation at 550-600 ?which becomes the pearlite. At the beginning, the austenite around the carbides decomposite, and the range then gradually expands. And at the beginning, the pearlite is lamellar. With the increase of the temperature, it tends to grainy. When it is heated to above the eutectoid temperature, the organization of the pearlite type will produce the recrystallization of austenite. This process is a formation and growth process for the austenitic core on the phase interface.In the Impact Crushers Liner heating process of the high-manganese steel, if the Impact Crushers Liner heating rate is fast enough, the austenite can not precipitate the carbides. There will no eutectoid reaction. By this point, we can control the Impact Crushers Liner precipitation of carbides in high-manganese steel heating process. Managing to reduce the precipitation of carbides in the Impact Crushers Liner heating process is helpful for the performance of steel.

In the actual operation, since the furnace temperature and heating rate is related to the specific conditions of the Impact Crushers casting, we can carry out the operation according to the Impact Crushers actual practice.
