The formula for calculating the ingredients of the induction furnace ramming material:

1. Batching quantity = loading quantity-total amount of ferroalloy-iron input quantity of ore-remaining steel return to furnace;

2. Loading amount = tapping amount / comprehensive steel recovery rate;

3. Iron ore input amount = iron ore addition amount × iron content × iron income rate. The ore addition amount is generally calculated at 4% of the tapping volume, the iron content of the ore is 55%, and the iron recovery rate According to 80% recovery, the total comprehensive recovery rate of charge fluctuates between 92~96%, and it is generally calculated at 94%.
