First of all, we start with raw materials to judge whether the silicon residue is good or bad.

　　The manufacturers familiar with silicon slag know that the main raw material of silicon slag is ferrosilicon slag, which is ground into powder and made into silicon slag. The main smelting materials of ferrosilicon slag are silica, coke, etc., in which silica is very Important is also an important factor in determining the quality of silicon slag, so the application of silica is an important part of smelting silicon slag.

　　Then we are talking about the second raw material that affects the quality of silicon slag - coke

　　Coke as a combustion improver and heating material for smelting silicon slag is also an important factor affecting the quality of silicon slag. The control of coke should be lower in black cloth and less in water. Why is this controlled? That is because if If the ash is too high, it will affect the air permeability of the ferrosilicon. If the water content is too high, it will affect the stability of the furnace temperature and affect the quality of the silicon slag!
