Induction heating surface quenching induction heating equipment has the following advantages compared with conventional heat treatment:
1. Induction heating is directly heated by the internal heat source, and the heat loss is small, so the heating speed is fast and the heat efficiency is high.
2. During the heating process, due to the short heating time, the surface of the part is less oxidized and decarburized. Compared with other heat treatments, the scrap rate of the parts is extremely low.
3. After induction heating and quenching, the surface hardness of the parts is high, the core maintains good plasticity and toughness, and exhibits low notch sensitivity, so the impact toughness, fatigue strength and wear resistance are greatly improved.
4. It can perform selective heating.
5. Induction heating surface quenching mechanical parts are less brittle, and at the same time improve the mechanical properties of the parts (such as yield point, tensile strength, fatigue strength). The quenching hardness of steel parts that are also subjected to induction heating surface quenching is also higher than ordinary. The quenching hardness of the furnace.
6, induction heating equipment can be placed in the processing line, through the electrical parameters of the process of three lines of precise process control.
7, using induction heating quenching, ordinary carbon structural steel can be used instead of alloy structural steel to make parts without reducing the quality of parts, so under certain conditions can replace the complex chemical heat treatment.
8. Induction heating is not only applied to the surface quenching of parts, but also to the inner hole quenching of parts, which cannot be achieved by conventional heat treatment.
9, induction heating equipment is compact, small footprint, easy to use (ie easy to operate).
10, the production process is clean, no high temperature, good working conditions.
