How to control the Recarburizer Using

The recarburizer absorption rate affects the chemical composition of the molten iron. The recarburizers with different proportions of silicon, manganese, carbon, and sulfur have very different absorption rates during the melting process of the electric furnace. The effects of silicon, manganese, carbon, and sulfur decrease sequentially.




 

 

1. Each time the initial carbon content increases by 0.1%, the recarburizer absorption rate decreases by about 1% to 2%;

2. For each 0.11% increase in the initial silicon content, the absorption rate of the recarburizer will decrease by about 3% to 4%;

3. For each 0.1% increase in the initial sulfur content, the recarburizer absorption rate decreases by about 1% to 2%;

4. For every 0.1% increase in the initial amount of manganese, the recarburizer absorption rate will increase by about 2% to 3%. It can be calculated according to this ratio.
 

When the initial carbon content in the molten iron is high, under a certain dissolution limit, the recarburizer has a slow absorption rate, a small amount of absorption, a relatively large burning loss, and a low recarburizer absorption rate.

When the initial carbon content of the molten iron is low, under a certain dissolution limit, the recarburizer absorbs quickly, absorbs more, burns relatively little, and the recarburizer has a high absorption rate.

Silicon and sulfur in the molten iron hinder the absorption of carbon and reduce the absorption rate of the recarburizer. The manganese element helps the absorption of carbon and improves the recarburizer absorption rate. As far as the impact is concerned, silicon is the largest, followed by manganese, and carbon and sulfur are less affected.
