What are the advantages of electromagnetic stirring in induction furnace?
The beneficial effects of liquid steel electromagnetic stirring on smelting are as follows.
1. Uniform liquid steel temperature
The temperature of the upper and lower parts of the molten steel in the large capacity crucible is higher, and the main means to achieve uniform temperature is electromagnetic stirring. Large induction furnace uses dual frequency power supply, and one of the lower frequency power supply is specially used for mixing.
2. Uniform chemical composition of steel and alloy
Electromagnetic stirring is especially necessary for homogenizing chemical composition, especially for alloy elements with large density difference, such as aluminum, tungsten and molybdenum.
3. Improve the kinetic conditions of metallurgical physicochemical reaction
The reaction process of diffusion, dissolution and deoxidation can be accelerated by electromagnetic stirring, and the smelting cycle can be shortened.
