Silicon slag ball using for foundry

Silicon slag is a kind of scum floating on the furnace in the process of metal silicon smelting. Silicon slag contains a large amount of metal silicon and other elements, and is a good deoxidizer. Due to the different uses of silicon, there are many types of silicon slag, which can be roughly divided into industrial silicon slag, solar silicon slag, semiconductor silicon slag, and the like. The value of silicon slag itself is also very large, and it can be recycled or used as a deoxidizer.

What are the uses of silicon slag?

The main purpose of silicon slag is to be used as a deoxidizer and to refine industrial silicon in silicon slag. As a deoxidizer, it can reduce costs and increase profits. Silicon slag contains some silicon components that can also be used for purification. Industrial silicon, etc. Silicon slag is also a "star" in the field of deoxidation. Because of its low price and silicon content, steelmakers are more inclined to silicon slag products when purchasing ferroalloy raw materials for steelmaking, while desulfurization methods Silicon slag performs equally well, mainly because the silicon slag contains a large amount of alkaline oxides, which can react with sulfur oxides to form sulfates, and the slurry can be used for flue gas desulfurization.

Silicon slag can also be used for steel slag smelting pig iron, general casting, etc. Silicon slag can improve furnace temperature, increase the fluidity of iron, high-quality slag discharge, increase labeling, and update the toughness and cutting of iterative castings. ability. In the process of stainless steel refining in household electric furnaces, silicon slag is used as a reducing agent to upgrade efficiency and output.
