High Carbon silicon is an additive in steel smelting and is often used instead of ferrosilicon. The silicon in the High Carbon silicon can react with the oxygen in the molten steel to form silicon dioxide impurities, which float on the surface of the molten steel for easy removal. Moreover, the reaction between the High Carbon silicon and silicon is an exothermic reaction, and the temperature of the molten steel is also certain Lifting effect. The carbon in High Carbon silicon is also effective for supplementing the carbon source in molten steel. Let's take a look at the characteristics of carbon in High Carbon silicon.
High Carbon silicon is a common metallurgical material, mainly used in steelmaking. This is a common understanding of High Carbon silicons, but many people don’t know why High Carbon silicons are used in steelmaking. What role does steel play. In order to improve this situation and to allow everyone to have a more extensive and in-depth understanding of High Carbon silicons, a brief explanation will be made on the role of High Carbon silicons in steelmaking.
Carbon is often referred to as the "controller" because of its effect on the properties of steel. Although carbon itself does not have strength and hardness, as iron carbide Fe3C in solid solution, carbon is the primary controlling element of strength and hardness. The main function of carbon is that with the increase of carbon content in steel, it can increase the strength, hardness and hardenability of steel; but it reduces plasticity, toughness, magnetic and electrical conductivity. Carbon and certain alloying elements in steel combine to form various carbides, which have different effects on the properties of steel.
In the early stage of steel smelting, a certain amount of oxygen is added to remove the carbon in the molten iron, thereby transforming the molten iron into molten steel. However, excessive oxygen in the molten steel will affect the quality of the steel, and some deoxidizers will be added to reduce For oxygen removal, some recarburizers will also be added to increase the carbon in the molten steel. The addition of High Carbon silicon not only effectively removes the oxygen in the molten steel, but also helps increase the carbon content in the molten steel.
