Brief Introduction to Silicon Slag
Silicon slag is what is left after refining the original silicon ore and contains a large amount of silicon. As one of the metallurgical materials purchased in large quantities by production companies, silicon slag 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, and semiconductor silicon slag. Silicon slag itself has high utilization value and can be recycled and used as a deoxidizer.
How to Produce Silicon Slag?
The process of producing silicon slag is the process of smelting metallic silicon and ferrosilicon. After smelting metallic silicon and ferrosilicon, metallurgical slag will be produced at the bottom or wall of the electric furnace. These metallurgical slags are the source of silicon slag. Through processing, silicon slag can be processed into granular and block shapes. In order to rationally apply silicon slag, it is also ground and loaded with alloy powder, and is made into various grades of ferroalloy balls through a briquetting machine for steelmaking and casting needs.
Benefits of Silicon Slag
Reduce Costs
Silicon slag can participate in the purification process of other ferroalloy products and can effectively improve the silicon purity of ferroalloy products. Moreover, it costs less than other materials.
Effectively Increase Furnace Temperature
Putting silicon slag into the steelmaking process has the effect of increasing the furnace temperature, which can provide a stable high-temperature environment for the smelting materials, thereby achieving better smelting results.
Improve Steel Grade
Silicon slag alloys can help steel manufacturers improve steel grades. For example, using silicon slag alloys in casting can also improve progressive toughness and cutting capabilities.
Improve the Fluidity of Molten Steel
During the steelmaking process, oxides are formed due to the reaction between molten steel and oxygen. If not removed promptly, the opening will become clogged. Silicon slag can effectively gather and filter oxides to solve the above problems.
Environmental Protection
Silicon slag can be used in the steel slag recycling process to remelt the steel slag generated during the steelmaking process to produce pig iron or steel. This can not only greatly increase the output of steelmaking, but is also very environmentally friendly.
Solve the Shortage of Silicon Materials
Silicon slag can be remelted, which means you can obtain silicon by remelting it to recrystallize it to cope with the current silicon shortage and rising prices.

Several Common Types of Silicon Slag
Silicon Slag 60
This silicon slag contains 60% silicon and is mainly used by manufacturers as a deoxidizer in the steelmaking process. Silicon slag 60 has inherent advantages over ordinary ferro alloy products. It is low in price and has very good deoxidation effect, and can effectively replace relatively expensive products such as ferrosilicon and metallic silicon. The use of silicon slag 60 in steelmaking can increase the furnace temperature and improve the steelmaking recovery rate. Its use can effectively reduce production costs.
Silicon Slag 50
Silicon slag 50 contains about 50% silicon. Its price is more affordable than other traditional ferro alloy products and can be used in deoxidation, casting, steelmaking and other industries. By shortening the deoxidation time, silicon slag 50 can improve steelmaking efficiency. It can effectively reduce production costs and recycle tight resources.
Silicon Slag 40
Silicon slag 40 contains 40% silicon and is an important metallurgical raw material used for purification and recrystallization. Many manufacturers often use silicon slag 40 times to make iron for ordinary casting. It is low in price and can effectively increase the furnace temperature and increase the flow of molten iron. It is a good metallurgical material.
Silicon Slag Uses
Deoxidizer
As a deoxidizer, silicon slag can reduce costs and increase profits. Because it is less expensive and contains a certain amount of silicon. Steel mills prefer to use silicon slag products when purchasing raw materials.
Desulfurizer
Silicon slag contains a large amount of alkaline oxides, so they can react with sulfur dioxide to form sulfate. Its slurry can be used for flue gas desulfurization.
Refining Industrial Silicon
Silicon slag generally contains at least 15% elemental silicon, so further extraction and separation of silicon slag can obtain a certain amount of silicon element. This method of refining industrial silicon not only saves silicon wafer waste, but also reduces expenses to a certain extent. Industrial silicon slag is also widely used in the metallurgical industry.
Strengthen Steel Properties
Silicon slag can also be used for steel slag remelting pig iron, general casting, etc. It can increase the furnace temperature, increase the fluidity of molten iron, 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 increase efficiency and production.
Why does Silicon Slag Allow Manufacturers to Increase Profits?
Silicon slag also contains a certain proportion of silicon. When purchasing metallurgical materials, many manufacturers have higher requirements for silicon content, but do not pay attention to the requirements for other elements. If you buy ferrosilicon and metallic silicon, it is easy to produce waste, so cheaper silicon slag is obviously a wise choice. After excluding high-iron alloy products, silicon slag products with high silicon content can meet the requirements and can save metallurgical costs while ensuring the production of high-quality products. In this way, silicon slag can help manufacturers save smelting costs and improve profitability.
