Products Description
Ferro silicon powder is a kind of powdered material obtained by grinding iron alloy composed of iron and silicon. Ferro silicon powder is not easy to be oxidized and can be stored for a long time. It has the characteristics of high-temperature stability, high strength, high hardness and high wear resistance.
The content of silicon in ferrosilicon powder is usually high, which makes ferrosilicon powder show unique advantages in many industrial fields. Ferrosilicon powder is an efficient deoxidizer, which can quickly combine with oxygen in molten steel during steelmaking to form silicate insoluble in molten steel, thus effectively removing oxygen from molten steel.
Ferro silicon powder is a strong deoxidizer in the steelmaking process, which is used for precipitation and diffusion deoxidization. Adding silicon to steel can significantly improve the strength, hardness and elasticity of steel, so ferro silicon powder is also used as an alloying agent. In addition, it can also be used as a heating agent for the ingot cap. The quality and recovery rate of steel ingot can be improved by using the characteristic that ferro silicon powder can release a lot of heat when it is burned at high temperatures.
Adding ferro silicon powder to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite. It is an important inoculant and spheroidizing agent in the production of ductile iron. High-silicon ferrosilicon powder (or silicon alloy) is a common reducing agent in the production of low-carbon ferroalloy in the ferroalloy industry. The ground or atomized ferrosilicon powder can be used as a suspension phase. In summary, ferro silicon powder is an important metallurgical raw material. Its high silicon content and excellent performance make it widely used in iron and steel smelting, casting, ferroalloy production and other fields.
