For the undercarriage parts of large bulldozers such as the D9N, D9R, and D9T, we have stricter requirements for the material, surface finish, hardness, and wear resistance of the track roller shaft. We also choose well-known brands for O-rings, seals, and lubricants, and carefully screen all components of the track roller to ensure the long-term stable operation of the bulldozer's undercarriage. This helps improve the working efficiency of the bulldozer and creates value for our customers.

The heat treatment process for our product Caterpillar D9N D9R D9T single track roller involves several steps to ensure its mechanical properties and durability. The following is a detailed description of the heat treatment process:

Heating: First, the roller blank is subjected to forging heat treatment to reach a specific temperature. This step typically uses induction heating or furnace heating methods to control the temperature.

Forging: Once the desired temperature is reached, the material is forged to enhance its strength and structural integrity.

Quenching: The residual heat from forging is then used for quenching treatment. Quenching involves rapidly cooling the material to alter its microstructure, thereby increasing hardness and wear resistance.

Tempering: After quenching, the roller undergoes tempering to relieve internal stresses generated during the quenching process and further optimize the material's mechanical properties.

Surface Hardening: To improve the hardness and wear resistance of the working surface, the surface of the track roller needs to be subjected to surface hardening. This step can utilize induction heating, but it is important to note that the induction effect may be weaker on rounded corners and that the hardening depth may be shallow.

Finishing: After completing the above heat treatment steps, the track roller requires finishing to meet precision requirements.

Quality Inspection: Finally, the track roller undergoes comprehensive quality inspection to ensure it meets technical standards and performance requirements.

Overall, the heat treatment process not only enhances the hardness, wear resistance, and strength of the track roller but also extends its service life. However, this process is relatively complex, has a long production cycle, high energy consumption, and incurs higher costs.
