How to solve the molten iron fluidity of the gray iron melted by the induction melting furnace?

The induction melting furnace itself has the ability to stir molten steel

1. Do not have too many impurities in raw materials, such as AL2O3.

2. The molten iron needs to be tempered.

3. Add the appropriate reagents.

4. Increase the melting temperature. (Unless you are out of the furnace in advance or you have purchased a defective induction melting furnace, the efficiency of the equipment is too low, and the molten steel that does not reach the rated temperature is out of the furnace)
