Row wheel dedicated medium frequency quenching equipment
Row wheels are components that are more susceptible to damage. According to the characteristics of driving, the wheel tread is required to have high hardness, and has a certain depth of hardened layer and transition layer (depth > 10mm, hardness HRC40-48) to improve load bearing capacity, wear resistance and fatigue resistance. . At the same time, the matrix structure is required to have good comprehensive mechanical properties and good organization. The hardness should reach HBS187-229, which makes it have high toughness, improved impact resistance and resistance to cracking. In order to achieve this characteristic, the heat treatment of the wheel surface is in place.
1. IF wheel quenching equipment
Adopting IGBT module, the circuit adopts uncontrolled full-bridge rectification, adopts series resonance multi-channel closed-loop control 'capacitance filtering, bridge inverter, series resonance output. High power factor, high reliability, low failure rate 100% load, deep layer: 4~8mm
Second, technical parameters:
Input power: 200KW
Working frequency: 2~8KHZ
Maximum output current: 300A,
Power supply 300A,,
Third, special sensors for wheel quenching equipment:
The contour sensor is quenched by heating to a flat surface or a groove, so a magnetizer is added, and the quenching process is completed once by heat quenching.
Fourth, the wheel quenching tooling
In order to ensure the uniform hardness of the wheel quenching, the quenching process must be done with the tooling (user can make it by yourself or consult the manufacturer's technical guide).
The role of the tooling is to make the wheel of the wheel rotate in a uniform axial direction. The rotation can be adjusted according to the size of the wheel and the requirement.
