As a Refractory Slide Gate Supplier, let's talk to you about the reasons for 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 is increased, the slag moves on the line, which threatens the furnace cap and affects the gun position control. Therefore, it must be eliminated during the smelting process. The main reason for the increase is the slag over-bonding.
