Silico Manganese Chemical Composition

 

The silico manganese chemical composition is mainly silicon and manganese. Silicon is a common non-metallic element with good electrical and thermal conductivity. Manganese is an important metal element with excellent mechanical properties and corrosion resistance. By alloying silicon and manganese, silicon-manganese alloy can improve the properties of steel, increase its hardness and wear resistance, and also enhance the toughness and strength of steel. It is mainly used in industrial production, such as steel smelting and preparation of alloys.

Manganese ore is the main raw material of silicon manganese alloy, so the choice of manganese ore is very important. It directly determines the smelting effect. Usually, the manganese content of furnace ore after mixing is required to be more than 30%. Because the manganese content of manganese ore has a significant effect on smelting index, unit product power consumption and manganese recovery rate. Improving the quality of manganese ore in the production process is the key to optimising the smelting process, reducing power consumption and improving other indicators.

 

 

At the same time, the production personnel also need to pay attention to the content of iron and phosphorus in the incoming manganese ore. When smelting silicomanganese alloys, about 95 per cent of the iron and 75 per cent of the phosphorus in the charge goes into the alloy. And the main source of iron and phosphorus is precisely manganese ore. Therefore, their contents have a direct impact on the quality of manganese-silicon alloy. In order to ensure the smelting of qualified products, it is necessary to match manganese ores of different compositions according to the application areas and requirements, so that the blended manganese ores can meet the requirements of smelting technology.

 

 

Manganese recovery rate is also a complex indicator, which is affected by many factors such as raw material, furnace condition, product grade and so on, with a wide range of fluctuation. In the dosage calculation, the manganese recovery rate needs to be determined specifically according to the material balance and actual demand. In view of the special characteristics of silicomanganese smelting, a variety of manganese ores are usually used to produce manganese-silicon alloy. In order to maintain stable furnace conditions and achieve good economic and technical indicators, in addition to controlling the manganese-iron ratio and manganese-phosphorus ratio of the mixed ores, it is also necessary to ensure that the various effective components in the mixed ores are close to the requirements of process control.
