Silicon Slag

Advantages of Silicon Slag:

Silicon Slag effectively increases furnace temperature, enhances fluidity of molten iron, facilitates efficient slag removal, and improves the toughness and machinability of castings. Stainless steel manufacturers use it as a reducing agent during the electric furnace refining process to enhance efficiency and output.

Applications of Silicon Slag:

Silicon Slag is primarily used as a deoxidizer and for refining industrial silicon from slag. As a deoxidizer, it reduces costs and increases profits. The silicon content within can also be utilized for purifying industrial silicon. In the deoxidation field, Silicon Slag is preferred due to its lower cost and silicon content, making it a favored choice in steelmaking for alloy materials procurement. It also excels in desulfurization, reacting with sulfur dioxide to form sulfates, whose slurry is useful in flue gas desulfurization.

Silicon Slag is also employed in processes like steel slag recycling to produce pig iron and in general casting. Its use enhances furnace temperature, improves molten iron flow, facilitates high-quality slag removal, increases grade specifications, and updates the toughness and machinability of castings. In stainless steel production, it serves as a reducing agent during electric furnace refining, boosting efficiency and output.

How to Distinguish Quality of Silicon Slag:

1. Color: Quality Silicon Slag can be quickly identified by its color. Higher silicon content typically results in a greener hue, while lower content may appear gray. Silicon Slag with silicon content between 50% to 90% tends to be black. Evaluating color provides a rapid means to select high-quality Silicon Slag.
2. Certification: Checking the certification of Silicon Slag products before purchase ensures quality assurance from the manufacturer.
