Under the action of alternating loads such as torsion and bending and impact loads, the surface of the chain bears higher stress than the core. In the case of friction, the surface layer is continuously worn, so the requirements for high strength, high hardness, high wear resistance and high fatigue limit are put forward for the surface layer of the chain. Only surface strengthening can meet the above requirements. Because surface induction hardening has the advantages of small deformation and high productivity, it is widely used in production. Chain induction hardening, now more equipment is high-frequency induction hardening equipment.
The chain is quenched and heat-treated by high-frequency induction hardening equipment. The sensor is a copy sensor made according to the chain specification, which can ensure the uniformity of quenching to the greatest extent, and there will be no defects that cannot be quenched in some parts. What's better is that the heating method is very flexible, which can not only carry out overall quenching heat treatment on the chain, but also partial quenching heat treatment, which can meet different requirements of customers.
The high-frequency induction hardening equipment is 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. The operation is intuitive, simple and convenient. The chain quenched by this equipment has no oxidation phenomenon, decarburization phenomenon, crack and deformation defect, and the service life is greatly improved, which meets the needs of work.
