What is the bottom of the furnace?

What is the main reason for the rise in the bottom of the furnace?

The so-called bottom rise is the gradual increase of the bottom of the furnace during the smelting process, as if it is on the original lining, and a new layer of refractory material is applied. This is a new problem caused by improper operation of dolomite slag.

As the bottom of the furnace increases, the slag moves on the line, threatening the furnace cap and affecting the control of the gun position. Therefore, it must be eliminated during the smelting process. The main reason for the increase is the result of excessive slag.
