Let's talk about the advantages of medium frequency induction heating equipment for annealing workpieces

Induction annealing is because the workpiece is cooled in the air after being heated to the annealing temperature. Therefore, it is actually induction normalizing, but it is customarily called annealing. At present, we often use medium frequency induction heating equipment to anneal workpieces. Today, we will talk about which workpieces can be annealed using medium frequency induction heating equipment and its advantages.

The annealing of medium frequency induction heating equipment is widely used in the annealing of steel pipe welds, the recrystallization annealing of workpieces after cold heading (such as high-pressure oil joints), and some workpieces that require local annealing after carburization (such as motorcycle connecting rods, splines Shaft thread classification). The annealing of the steel pipe weld causes the coarse and uneven grains of the weld to be normalized to obtain fine grains; the local annealing of the cold heading parts restores the elongated grains after cold heading to fine and uniform grains to prevent this part of the workpiece from being Damage due to reduced mechanical properties during use; parts of the carburized parts, such as the thread part, are annealed, mainly to reduce the hardness of this part.

Advantages of using medium frequency induction heating equipment to anneal workpieces:

1. Fast heating: Fast heating speed results in uniform heating, and the heating speed can be adjusted and controlled.

2. High efficiency: The equipment has an automatic setting function, and the operation can be completed by one person, thus reducing the number of processes and improving efficiency.

3. Wide application: can heat metal workpieces of various types of work. (The induction coil is made according to the shape of the workpiece)

4. Low power consumption: The thermal efficiency reaches more than 95%, so it is more energy-saving than other heating methods (such as gas, oxygen, acetylene, coking coal, electric furnace, high frequency electronic tube, etc.).

5. Good environmental protection: no noise, pollution and open flames, making it easier to meet environmental protection and fire protection requirements.

6. Temperature controllable: The heating temperature of the workpiece can be controlled by setting the heating time, so that the heating temperature can be controlled to a technical point.

7. Uniform annealing temperature

8. Fast heating speed. The heating time of ordinary heat treatment (such as quenching and annealing) generally does not exceed 10 seconds per piece, which solves the problem of the oxide layer being too thick due to the long heating time of the traditional heat treatment process.

9. The annealing position can be freely controlled and will not generate too much heat in locations that do not require heating, meeting the heat treatment requirements for special work.
