The service life of a mold has a lot to do with the material of mold steel. If the mold steel is not handled properly, it will break. What kind of solutions can be found to solve the problem of fracture of Henan mold steel.

1、对原材料进行改锻，多次双十字形变向镦拔锻造，经四镦四拔，使锻造纤维组织围绕型腔或轴线呈波浪形对称分布，并利用较后一火高温余热进行淬火，接着高温回火

1. The raw materials were forged by changing the direction of double cross forging for many times. After four upsetting and four drawing, the forged fiber structure was symmetrically distributed in a wavy shape around the cavity or axis. The high temperature waste heat was used for quenching and then high temperature tempering

2、制订的热处理工艺，控制淬火残余奥氏体含量不超标

2. According to the heat treatment process, the content of quenched retained austenite should not exceed the standard

3、淬火后及时进行回火、消 除淬火应力

3. After quenching, tempering should be carried out in time to eliminate quenching stress

4、适当降低磨削速度、磨削量，磨削冷 却速度，能有用防止和避免磨削裂纹形成

4. If the grinding speed, grinding amount and cooling rate are properly reduced, the formation of grinding cracks can be effectively prevented and avoided
