Jan 21, 2025
1.) Production method of high carbon ferrosilicon
High carbon ferrosilicon is an alloy of iron, carbon, silicon and other elements. It has good hardness, toughness and corrosion resistance and is widely used in steel, casting, refractory materials and other industries. Its production method is as follows:
1. Raw material preparation: Use high-quality coke, quartz stone, manganese ore and other raw materials and mix them in a certain proportion.
2. Charge addition: Add the mixed charge to high-temperature smelting equipment such as electric furnace, furnace bottom, slag pit, etc.
3. Melting reduction: Perform high-temperature smelting and reduction reaction to reduce oxides such as silica and manganese ore in the charge to metallic silicon, manganese and other elements, and react with coke to form high carbon ferrosilicon alloy.
4. Pouring and discharge: After smelting, the high carbon ferrosilicon alloy is poured into a pre-made mold and discharged after solidification.
2.) Application of high carbon ferrosilicon
Due to its good physical and chemical properties, high carbon ferrosilicon is widely used in steel metallurgy. Its main applications are:
1. Casting field: High carbon ferrosilicon alloy can improve the fluidity and lubricity of molten iron during the casting process, enhance the corrosion resistance of castings, and is widely used in various casting processes.
2. Steel smelting: As a strong reducing agent, high carbon ferrosilicon alloy can help reduce the oxide content during steel smelting and improve the quality and composition uniformity of steel.
3. Refractory materials: High carbon ferrosilicon alloy can be sintered with quartz sand, dolomite and other materials in a certain proportion to make high temperature refractory materials for smelting molten metal, glass and other high temperature processes.
In summary, high carbon ferrosilicon is an important ferroalloy material, which requires the use of high-quality raw materials and is generated through high temperature smelting and reduction reactions. In the fields of steel smelting and casting, high carbon ferrosilicon alloy plays an important role.
