Ferrosilicon is an alloy of iron and silicon. Ferrosilicon is an iron-silicon alloy made of coke, steel chips, quartz (or silica) as raw materials and smelted by electric furnace. Since silicon and ox

1. Ferrosilicon and manganese silicon are the most used iron alloys in the steelmaking process, and the biggest difference is that the first is the production of raw materials. Second, the use of diff

Ferrosilicon is an alloy made of a certain proportion of silicon and iron. It has some unique properties such as high hardness, high melting point, high permeability and good corrosion resistance. Fer

1. Used as deoxidizer and alloying agent in steelmaking industry. In order to obtain the chemical composition of qualified steel and ensure the quality of steel, in the final stage of steelmaking must

Raw materials of ferrosilicon: coke, steel chips, quartz (or silica) as raw materials, made of electric furnace smelting. The cost composition of ferrosilicon: production cost = silica + steel chips +

Ferrosilicon is widely used in the iron and steel industry, the casting industry and other industrial production. Ferrosilicon is an essential deoxidizer in steelmaking industry. In steelmaking, ferro

There are many uses for ferrosilicon, such as: 1, in the field of steelmaking industry, it can be used as "deoxidizer" and "alloying agent". 2, in the field of cast iron industry,

Low-silicon ferrosilicon (10 ~ 15% silicon) can be smelted in blast furnaces with iron ore and silica. High coke ratio and wind temperature are required. In operation, the top temperature of the furna

Ferrosilicon is an essential deoxidizer in steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying ag

Characteristics of refractory materials: The special functional role played by the metallurgical process in use is often used as a single component or combined with some auxiliary refractory products,

Alumina content is greater than 90%, corundum brick as the main crystalline phase of refractory products. High compressive strength at room temperature (up to 340MPa). High load softening initial temp

Fused corundum is made from forged alumina or bauxite, which is melted in a restored atmosphere by electric arc furnace, separated from metals and other impurities, and then condensed. Depending on th
