Low Cost Silicon Slag Alternative

1.Silicon content from 30~50% is used for silicon addition for iron making in the blast furnace and cupola.

2. Silicon content from 50~70% is used for the deoxidization of steel making.

3. It is a good substitute for FeSi in steel making, which has advantage in lowing the cost of production and reusing resource

Silicon slag can also be used for smelting pig iron and ordinary castings with steel slag. Silicon slag can increase furnace temperature, increase the fluidity of hot iron, discharge high-quality slag, increase labeling, and update the toughness and cutting ability of iterative castings. Stainless steel production enterprises use silicon slag as a reducing agent in the process of electric furnace smelting of stainless steel to improve efficiency and output.

Silicon slag with a factory price of 60% is cheap and contains 60% silicon element. Its main use is as a deoxidizer in the steelmaking process for steelmaking manufacturers. Compared with ordinary ferroalloy products, silicon slag 60 has inherent advantages. Although it has a lower factory price, its deoxidation effect is very good. It can be effectively used by manufacturers to replace relatively expensive products such as silicon iron and metallic silicon. The use of silicon slag 60 can effectively reduce production costs for manufacturers, reduce deoxidation time, and improve steelmaking efficiency. When steelmaking, the use of silicon slag 60 can increase furnace temperature and increase steelmaking recovery rate.

The content of silicon element in silicon slag 50 is about 50%. The factory price of silicon slag 50 is relatively affordable compared to other traditional iron alloy products, and it can be used in multiple industries such as deoxidation, casting, and steelmaking. The use of silicon slag 50 in the production process of manufacturers can effectively reduce production costs and promote resource recycling, greatly reducing deoxidation time and improving steelmaking efficiency.

Silicon slag 40 is the remaining part of the raw ore with a silicon content of 40% after being refined by ferroalloy manufacturers. Silicon slag 40 is an important metallurgical material used for purification and recrystallization in the furnace. Silicon slag 40 manufacturers often recycle silicon slag 40 into pig iron and ordinary casting. Silicon slag is inexpensive, but it can effectively increase the furnace temperature and increase the fluidity of molten iron, making it a good metallurgical material.
