Silicon carbon alloy is a new type of alloy with converter alloy, is a new metallurgical material through the rapid development of metallurgical industry, its price is cheaper than traditional metallurgical materials, but can replace the traditional iron silicon, silicon carbide, carburizer and other metallurgical materials used for converter smelting deoxidation alloying process.
Silicon carbon alloy contains silicon element, in the process of steelmaking, after adding silicon carbon alloy, the silicon element and oxygen affinity reaction occurs to make the oxygen deoxidation in the molten steel to improve the hardness and quality of steel, and the silicon element in the silicon carbon alloy has a good affinity with oxygen, so the molten steel also has the characteristics of no splash.
Silicon carbon alloy also has the advantage of slag collection, a certain proportion of silicon carbon alloy into the molten steel, can make the oxide in the process of steelmaking quickly clagging, easy to filter treatment, make the molten steel more pure greatly improve the density and hardness of steel.
Silicon carbon alloy is a good temperature resistant material, in the process of steelmaking, silicon carbon alloy can increase the furnace temperature, improve the conversion rate of iron alloy, and accelerate the reaction speed of molten steel and elements.
Application scenarios of silicon carbon alloy in iron and steel smelting
Deoxidation alloying process of converter smelting. Silicon carbon alloy can replace iron silicon, silicon carbide, carburizer and other metallurgical materials, used in converter smelting deoxidation alloying process, improve the chemical composition, mechanical properties and internal control quality of steel. In the process of converter smelting, the silicon element in the silicon carbon alloy reacts with oxygen to improve the hardness and quality of the steel, while not splashing, so that the molten steel has the characteristics of non-splashing.
Continuous casting process.
In continuous casting process, silicon carbon alloy can replace traditional metallurgical materials such as ferro silicon and silicon carbide, reduce the amount of deoxidizer and improve the quality of molten steel.
Steel smelting stage.
In the early stage of steel smelting, in order to convert the liquid iron with a lot of carbon content into liquid steel, it is necessary to fill a large amount of oxygen into the liquid iron for decarbonization. In this process, due to excessive oxygen content, carbon content will be lost. Therefore, when adding deoxidizer, it is also necessary to add carburizer. Silicon carbon alloy can replace the traditional carburizer, reduce the amount of deoxidizer and reduce the cost of steelmaking.
Steel smelting later.
In the later period of steel smelting, in order to improve the mechanical properties of steel and product properties, it is necessary to add various alloying elements. Silicon carbon alloy can replace the traditional alloy material, reduce the amount of alloy added and reduce the cost of steelmaking.
In short, silicon carbon alloy has a wide range of application scenarios in steel smelting, which can improve the quality of molten steel, improve product quality and internal control quality, and reduce steelmaking costs. At the same time, the use of silicon carbon alloy also has the advantages of simple operation and stable effect.
