Steel pillows are an important tool on railroads. During the working process, the steel sleeper has to bear huge friction force, so it wears out quickly. For this reason, many manufacturers use high-frequency induction hardening machine for quenching heat treatment, the effect is very good, the hardness and wear resistance are greatly improved, which meets the needs of the work.
High-frequency induction hardening machine, it is very fast when quenching and heat-treating the steel pillow, and can reach the required temperature in a short time, avoiding the occurrence of oxidation and decarburization, and ensuring the quenching effect of the steel pillow. The quenched steel pillow has a thicker tough area under the hard layer on the surface, and has better compressive internal stress, so that the fatigue resistance and breaking capacity of the steel pillow are higher, which meets the needs of the work.
The high-frequency induction hardening machine adopts IGBT inverter power devices, which are highly efficient and energy-saving, and the heating is easy to control. The heating current value and heating voltage value can be set, and the current, voltage, power and frequency are all displayed, and the operation is intuitive, simple and convenient. What's even better is that the equipment will not produce noise and dust during the working process, and will not produce waste smoke and waste gas, which greatly improves the working environment of workers and enables workers to achieve environmentally friendly production.
