Silicon-carbon alloy, is a metallurgical material that has undergone rapid development in the metallurgical industry. Its price is cheaper than traditional metallurgical materials, but it can replace traditional ferrosilicon, silicon carbide and other metallurgical materials. It has been used for steelmaking for a long time. Used by manufacturers to replace metallurgical materials such as ferrosilicon.
1. Advantages of deoxidation
The silicon-carbon alloy contains silicon element. After the silicon-carbon alloy is added in the steel-making process, the silicon element and the oxygen element undergo an affinity reaction to deoxidize the oxygen in the molten steel to improve the hardness and quality of the steel, and the silicon element in the silicon-carbon alloy Oxygen has a good affinity, so the molten steel still has the characteristics of not splashing after being put in.
2. The advantages of slag collection
Silicon-carbon alloys also have the advantage of slag collection. Putting a certain proportion of silicon-carbon alloys in molten steel can make the oxides in the steelmaking process clump quickly, which is convenient for filtration treatment, making the molten steel more pure and greatly improving the density and hardness of the steel.
3. The advantages of increasing furnace temperature
Silicon-carbon alloys are good temperature-resistant materials. Putting silicon-carbon alloys in the steelmaking process can raise the furnace temperature, increase the conversion rate of ferroalloys, and accelerate the reaction speed of molten steel and elements.
