Silicon carbide deoxidizer is a material composed of silicon carbide and other additives, its name is diverse, but the main components are silicon carbide, the common silicon carbide deoxidizer names are: black silicon carbide deoxidizer, gray silicon carbide deoxidizer, graphitized silicon carbide deoxidizer, graphitized silicon carbide deoxidizer and so on.

 

Silicon carbide deoxidizer is a novel high-performance composite deoxidizer, can replace the more expensive traditional deoxidizer iron silicon powder and gold powder, suitable for steel, alloy steel and special steel smelting deoxidize, with rapid deoxidization, slag early, thick reduction atmosphere, rich foam and other advantages, but also can effectively improve the recovery of elements, but also carburizing effect, instead of part of the carburizer, Greatly reduce the cost of steelmaking. The use of silicon carbide as a deoxidizer can make the quality of molten steel stable, and has the effect of refining grains and removing harmful impurities in molten steel, and the casting temperature of molten steel is high, the quality of casting billet is good and the unit cost is low.

 

 

Silicon carbide deoxidizer application

  1. Purify molten steel

The main function of silicon carbide deoxidizer is to remove oxygen elements in steel, thereby improving the purity of steel. It can reduce the iron oxide in the steel to metallic iron, and form gaseous CO with the carbon in it, thereby purifying the molten steel, reducing the impurity content, and improving the quality of the steel.

  1. Adjust the composition of molten steel

The silicon carbide deoxidizer can also adjust the composition of the molten steel, such as increasing the carbon content in the steel and reducing the sulfur content, so as to improve the performance of the steel.

  1. Improve liquidity of molten steel

Silicon carbide deoxidizer can also improve the fluidity of molten steel, reduce the content of gas, so as to ensure the uniformity and stability of molten steel.

 

 

The advantage of silicon carbide deoxidizer

 

Silicon carbide deoxidizer is a steel deoxidizer with good effect, high product utilization rate and low cost. Steelmaking deoxidizer, made of silicon carbide powder and crushed CaC2 mixed processing, steelmaking deoxidizer, silicon carbide weight percentage is 50-85%, CaC2 weight percentage is greater than 7%, and its weight percentage is less than 10%, the balance is the impurities in the product raw materials and product production process; The product particle size of silicon carbide deoxidizer is below 10mm. Silicon carbide deoxidizer used in steelmaking can meet the smelting deoxidizer needs of different steel grades, reduce the amount of silicon calcium barium, silicon aluminum calcium barium and other strong deoxidizer, can reduce the steel production cost of about 2.0 yuan/ton, improve the yield of alloy-element more than 1.5%, the composition fluctuation is small, and reduce the cost due to the reduction of the amount of CaC2W. And reduce the pollution to the environment.

 

Silicon carbide deoxidizer is used in steelmaking for deoxidation, made of silicon carbide powder and crushed CaC2 mixed processing, which is characterized in steelmaking deoxidizer, the weight percentage of silicon carbide is 50-85%, the weight percentage of CaC2 is greater than 7%, and its weight percentage is less than 10%, the surplus is the impurities generated in the product raw materials and the product production process; The particle size of the product is below 10mm.

 

The utility model relates to a composite silicon carbide deoxidizer used for deoxidizing molten steel in the technical field of iron and steel smelting. Made of silicon carbide powder and crushed CaC2 mixed processing, in which the weight percentage of silicon carbide is 50 ~ 85%, the weight percentage of CaC2 is greater than 7%, and its weight percentage is less than 10%, the remainder is the impurities produced in the product raw materials and the product production process; The particle size of the product is below 10mm. The deoxidizer used in steelmaking can meet the smelting deoxidization needs of different steel grades, reduce the amount of strong deoxidizer such as silicon calcium barium, silicon aluminum calcium barium, silicon carbide deoxidizer can reduce the production cost of steel about 2.0 yuan/ton, improve the yield of alloy-element more than 1.5%, the composition fluctuation is small, and due to the reduction of the amount of CaC2, the product utilization rate is high, which reduces the cost. And reduce the pollution to the environment.
