The role of electromagnetic stirring of aluminum liquid in medium frequency electric furnace
When the medium frequency electric furnace smelts aluminum, it uses an intermediate frequency electric furnace for smelting because it can control the temperature inside the furnace and reduce oxidation. In the process of smelting, the electromagnetic stirring of aluminum liquid in the intermediate frequency electric furnace can play a very good role in smelting. The main functions are reflected in the following aspects:
1. Medium frequency electric furnace uniform aluminum liquid temperature
In the large-capacity crucible, the upper and lower temperatures of the molten steel are relatively large, and electromagnetic stirring is the main means to reach a uniform temperature. Large induction furnaces use dual-frequency power supplies, one of which is dedicated to agitation.
2. The chemical composition of uniform aluminum and alloy in medium frequency electric furnace
Electromagnetic stirring is especially necessary for uniform chemical composition, especially for the homogenization of alloying elements such as aluminum, tungsten, molybdenum, etc., which have large differences in density.
3. Medium frequency electric furnace improves the kinetic conditions of metallurgical physicochemical reaction
Electromagnetic stirring can accelerate the reaction process of diffusion, dissolution, deoxidation and the like, and shorten the smelting cycle.
