What is silicon slag? What are the uses of silicon slag？

As we all know, silicon slag is widely used in steel mills and foundries. Silicon slag can be used as a high-quality raw material for smelting and casting pig iron and silicon-manganese alloy; silicon slag can improve furnace temperature, increase the fluidity of molten iron, and high-quality slag discharge. , increase the brand; silicon slag can also be used as a deoxidizer in steel production. Different types of silicon slag have different uses. Are you using it correctly?

Silicon slag, as one of the metallurgical materials purchased in bulk by manufacturers, has irreplaceable advantages. Most people think that silicon slag is a waste of useless ferroalloy slag. After being refined, it still contains a lot of silicon. 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 Bunsen is also very large, and it can be recycled or used as a deoxidizer.

How to classify silicon slag

Silicon slag can be divided into metallic silicon slag and ferrosilicon slag. Generally, the silicon content in silicon slag is about 50%--70%. needs to be customized.

Silicon slag with a silicon content of about 50% can be used in foundry, steelmaking, deoxidation and other industries, which can effectively reduce production costs and improve production efficiency.

Ferrosilicon slag can be used in place of ferrosilicon, and its price is cheaper than ferrosilicon. It can be used in electric furnaces, converters, and strong deoxidation and desulfurization capabilities. It can effectively improve the fluidity of molten steel, purify molten steel, reduce the effect of impurities in steel, and save production. cost.

Silicon slag is mainly a carbonized ferroalloy product, and its internal elements are mostly silicon slag (Sic). Generally, the product with higher silicon slag content is greener in color, while the lower silicon slag product is gray. , and the silicon slag with a silicon slag content of 50% to 70% turns black, so that we can see the color of the silicon slag product when selecting the silicon slag, and quickly select high-quality silicon slag by the color of the silicon slag.
