Most people think that silicon slag is useless alloy slag. In fact, people in steelmaking and foundry understand that silicon slag is left over from the original silicon ore after refining, and it also contains a large amount of silicon. Silicon slag is used as a production enterprise. One of the metallurgical materials purchased in large quantities has an irreplaceable advantage. 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, and semiconductor silicon slag. The silicon slag itself has high utilization value and can be recycled or used as a deoxidizer.Next, Gansu Xuanhuiyuan Metal will share the use of silicon slag in detail for you：
                                                                                                
                       

What is silicon slag:
Silicon slag is the residue left after silicon ore is refined, and the residue also contains a lot of silicon content. In addition, the uses of silicon slag are also relatively wide, and the types of silicon slag are different, of course, the uses are also different.

Use of silicon slag：
The purpose of silicon slag is mainly to be used as a deoxidizer and to refine industrial silicon in silicon slag. As a deoxidizer, it can reduce costs and increase profits. The silicon slag can also be used to purify industrial silicon, etc. It is also a "star" in the field of deoxidation. Because of its low price and containing silicon, steelmaking manufacturers are more inclined to silicon slag products when purchasing ferroalloy raw materials for steelmaking. The performance of silicon slag in desulfurization is also excellent, mainly because of silicon slag. It contains a large amount of alkaline oxides, which can react with sulfur dioxide to form sulfate, and its slurry can be used for flue gas desulfurization.

More important uses of silicon slag：

1、Silicon slag can also be used for steel slag refining pig iron, ordinary casting, etc.

2、Silicon slag can improve furnace temperature, increase the fluidity of molten iron, effectively discharge slag, increase markings, and update the toughness and cutting ability of iterative castings. 

3、In the process of re-smelting stainless steel with electric furnace, stainless steel manufacturers use silicon slag as a reducing agent to upgrade efficiency and output.
