When the initial carbon content of the iron solution is high, under a certain dissolution limit, the absorption rate of the carburetor is slower, the absorption amount is smaller, the combustion loss is greater, and the absorption rate of the carburetor is lower; When the initial carbon content of molten iron is low, the situation is exactly the opposite.
In addition, silicon and sulfur in the iron solution can hinder the absorption of carbon, reducing the absorption rate of the carburetor. Manganese helps to absorb carbon and increases the absorption rate of carburetors. From the perspective of impact degree, silicon has a greater impact, followed by manganese, and carbon and sulfur have a smaller impact. Therefore, in the actual production process, manganese should be added first, followed by carbon and silicon.
