Chain hardening by medium frequency induction heating machine

Chain, as we all know, it has to bear huge friction during the working process, therefore, we have very high requirements on the quality of the chain. Because of this, many chain manufacturers are now trying to improve the quality of the chain. How to improve it, we give you an idea, you can use medium frequency induction heating machine for quenching heat treatment.

Why use medium frequency induction heating machine for quenching heat treatment? Let's talk about why we need quenching first. Quenching is a heat treatment process that heats the workpiece to a certain temperature and then cools it rapidly with a quenching medium. The purpose is to improve the hardness, wear resistance and service life of the workpiece. The service life is improved and the quality is also improved. Therefore, The chain needs to be quenched and heat treated. As for why the medium frequency induction heating machine is used. This is mainly determined by the quenching depth of the chain. The quenching depth of the chain is usually 3-5mm. This depth can only be satisfied by the medium frequency induction heating machine.

Advantages of chain hardening by medium frequency induction heating machine

1. The heating speed is fast, which avoids the occurrence of oxidation and decarburization, and ensures the quenching quality of the chain.

2. The equipment performs quenching heat treatment on the chain, which directly heats the chain, so the heat loss is small, the heating speed is fast, and the thermal efficiency is high.

3. The surface hardened layer can be regulated by adjusting the power of the equipment as needed, so that the martensitic structure of the hardened layer is finer, and the hardness and strength are relatively high.

4. The quenching method is flexible, not only the overall quenching heat treatment can be carried out on the chain, but also the local quenching heat treatment can be carried out on the chain, which can meet the different requirements of customers;

5. After the chain is quenched by the medium frequency induction heating machine, there is a thicker tough area under the surface hard layer, which has better compressive internal stress, so that the chain has higher fatigue resistance and breaking capacity.
