Gear is made of high frequency induction heating equipment for quenching advantage

In order to improve the gear hardness, wear resistance and service life, we usually use high frequency induction heating equipment for quenching of gears. Why induction quenching so popular?

First of all, we should understand, gear is consumable, so the increase in hardness is its core technology.

The first step is to choose the gear material. Selection of metal hardness large, such as steel, the metal is very good.But the copper and aluminum this at work is easily deformed,so there is little the material with gear.

The second step, is to choose the process. In ancient times the sword should all be seen, are repeated heating, cleaning the bathroom, and then a good sword becomes very sharp. But can now be developed, not so old, have special quenchingmachine use. This machine is called high frequency furnace,some place called high frequency machine.

The third step is to choose the appropriate power. Power is too large, is a waste of resources, power is very small, but also a waste of time. But the use of power much, is the wise remark of an experienced person, more knowledgeable peopleteach better.

Today, we will simply say that the induction heatingequipment for gear induction hardening have what advantage.

1, reduce the deformation of workpiece, maintain stable size.

2, lower equipment cost, processing cost reduction gear.

3, close to the root fillet, with an extremely high residualcompressive stress, improves bending fatigue strength of gear teeth, with excellent strength gradient.

4, improve the metallurgical properties of parts, and eliminates the generation in the process of heat treatment,such as oxidation, decarburization.

5, compared with traditional gear quenching process, the pitch circle of larger depth of tooth, hardness and high strength, in the Addendum will not produce overheat andbrittle.

High frequency induction heating equipment for induction hardening has many advantages for gear, is more than 5 pointslisted above, this is the best equipment for heat treatment of workpiece.
