Ferrosilicon alloy is composed of iron and silicon. Ferrosilicon smelting raw materials: silica. Silica have a good anti-knock properties. Silica powder exports of rare earth ferrosilicon, and water loss due to the phase transformation of rare earth ferrosilicon powder factory, rare earth ferrosilicon powder fragmentation may occur in the heating process, it will seriously affect the permeability of the material plane. Silica to have a certain size when the furnace. Silica particle size is too small, it will contain more impurities of rare earth ferrosilicon powder, will seriously affect the permeability of the material plane. Ferrosilicon alloy is composed of iron and silicon. Ferrosilicon purposes: as a deoxidizer and alloying agent in steel industry. In order to obtain the chemical composition of the steel and qualified steel quality assurance, in the final stages of steelmaking must be deoxidation, silicon and oxygen chemical affinity between large and therefore ferrosilicon is strong steel deoxidizer for precipitation and diffusion deoxygenation. RE ferrosilicon powder company, greatly metallurgy (certified), rare earth ferrosilicon powder metallurgy greatly by Anyang Refractories Limited. Anyang greatly metallurgical Refractories Co., Ltd. (www.aydawei.com) (www.aydwyjgs.com) is Anyang, ferroalloy and products of leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum limits to meet customer needs. In much of metallurgical leadership with the staff warmly welcome all inquiries negotiations to create a better future greatly metallurgy.
