Usually, silicon slag is used for casting deoxidation, and the effect is better than that of lump ferrosilicon. So how to distinguish the quality of silicon slag?
First of all, we can start with the raw materials. The main raw material of silicon slag is actually ferrosilicon slag, which is ground into powder to make silicon slag. The main smelting materials of ferrosilicon slag are silica, coke, etc. Among them, silica is very important and is also an important factor in determining the quality of silicon slag. Therefore, the application of good silica is an important link in smelting silicon slag.
In addition, coke is also an important factor affecting the quality of silicon slag as a combustion aid and heating material for smelting silicon slag. The control of coke should be low in black cloth ash content and low in water content. If the ash content is too high, it will affect the air permeability of ferrosilicon. If the water content is too high, it will affect the stability of the furnace temperature and thus affect the quality of silicon slag!
