Products Description

Most people think that silicon slag is useless alloy slag. In fact, people in the steelmaking and foundry industry know that some 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 One of the metallurgical materials that manufacturers purchase in large quantities, it has irreplaceable advantages. 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, etc. Silicon slag itself has high utilization value and can be recycled or used as a deoxidizer.

Silicon slag is the residue left after silicon ore is refined, and the residue still contains a lot of silicon content. Moreover, the use of silicon slag is also relatively extensive, and the specifications of silicon slag also have different types, of course, the uses are also different.

The use 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. Silicon slag contains some silicon components and can also be used to purify industrial silicon, etc., silicon Slag is also a "star" in the field of deoxidation. Because of its low price and silicon content, steelmakers prefer silicon slag products when purchasing ferroalloy raw materials for steelmaking. Silicon slag performs equally well in desulfurization, mainly because silicon The slag contains a large amount of basic oxides, which can react with sulfur dioxide to form sulfate, and its slurry can be used for flue gas desulfurization.

Silicon slag can also be used for steel slag recycling pig iron, ordinary casting, etc. Silicon slag can improve the furnace temperature, increase the fluidity of molten iron, high-quality slag discharge, increase the label, and update the toughness and cutting ability of iterative castings. Stainless steel manufacturers use silicon slag as a reducing agent in the process of smelting stainless steel in electric furnaces to upgrade efficiency and output.

Classification of silicon slag: ferrosilicon slag and metal silicon slag

Silicon content: 30%-70%;

Metal silicon slag trace elements:

Fe: 1.5%-2.5%, Al: 3.0%-6.0%, Ca: ≤3.0%, C: ≤8.0%, S: ≤0.1%, P: ≤0.05%;
