Introduction of Forged crane trolley wheels:

Crane trolley wheels are components that are more susceptible to damage. According to the use characteristics of the driving, the wheel tread is required to have higher hardness, and has a certain depth of the hardened layer and a transition layer to improve the bearing capacity, wear resistance and contact fatigue resistance. performance. At the same time, it is required that the matrix structure should have good comprehensive mechanical properties and good microstructure, and the hardness should reach HBS187~229, which makes it have high toughness, improve impact resistance and crack resistance.


Processing process of crane trolley wheels:

Heat treatment: quenching and tempering (quenching + tempering) furnace loading method: vertical suspension into the furnace quenching: heating temperature 820---850 degrees, heat preservation 0.5---1 hours out of the furnace, after entering the water, the workpiece should be moving should not be static, Regular movements should be made according to the geometry of the workpiece. When the temperature of the workpiece in the water reaches about 300 degrees, the water can be air-cooled (if it can be oil-cooled better). Tempering: high temperature tempering after steel quenching, heating temperature is usually 560~600 °C, heat preservation for 1-2 hours, then air cooling
