Silico Manganese is also known as silicon manganese alloy. It is massive and has a silver luster. It is a composite deoxidizer often used in steelmaking. It is also a reducing agent used in the production of low-carbon ferromanganese and electro-silicothermal production of metal manganese. When steel is added to manganese iron alloy, it can be better reduced, and it can also enhance the toughness, hardness, strength, and elasticity of steel. Silicon is also an effective graphitizing medium, which can turn the carbon in cast iron into free graphitic carbon. Standard gray cast iron and ductile cast iron need to add at least 4% silicon. Most of the manganese and silicon elements are added to the molten steel in the form of ferromanganese, silicomanganese, and ferrosilicon.
Raw Material Composition of Silico Manganese
The silicon manganese alloy can be smelted in continuous operation in large, medium, and small submerged arc furnaces. At present, the silicon manganese alloy electric furnaces of major silico manganese manufacturers are developing in the direction of large-scale and fully enclosed. In order to ensure the qualification rate of silico manganese products, the ratio of ferromanganese and manganese-phosphorus in the ore needs to meet certain requirements. The higher the manganese content of the manganese ore used, the better the performance of all indicators.
The main requirements for raw materials in the production of silicomanganese are as follows:
- Silica, SiO2≥97%, P2O5＜0.02%, grain size 10-40mm directly, not doped with soil and other sundries;
- Coke: fixed carbon>84%, ash content <14%, small and medium electric furnaces use 3-13mm coke particle size, and large electric furnaces use 5-25mm;
- Manganese ore, the content of impurity P2O5 in manganese ore should be as low as possible. The particle size of manganese ore is generally 10-80mm, and the part less than 10mm does not exceed 10% of the total ore.
Silico Manganese Production Process
The silico manganese alloy is produced by reducing the manganese oxide and silicon dioxide in manganese ore and silica with charcoal in a carbothermic furnace. In the silico manganese smelting process, carbonaceous reducing agent, manganese ore, manganese-rich slag, sintered manganese ore, roasted manganese ore and silica are used as raw materials, and lime, dolomite, fluorite, etc. are used as solvents for continuous generation in the electric furnace.
