New type of silicon-calcium-manganese deoxidizer

Silicon-calcium-manganese deoxidizer is a new composite deoxidizer with a better deoxidation effect in steelmaking production. The existing silicon-calcium-manganese deoxidizer is smelted by an induction furnace. Because the raw material used is metal manganese or an alloy (silicon-calcium alloy) first smelted from ore, and then secondary smelted. Therefore the production process is loaded down with trivial details, the energy consumption is big, and the cost is high, affecting the price of the product. In particular, manganese, the main raw material, is expensive. Once the market is in short supply, it will directly affect the production of silicon-calcium-manganese deoxidizers.



A new type of silicon-calcium-manganese deoxidizer is a kind of ore with silicon, calcium, and manganese as raw materials. By selecting a suitable formula, it can be directly smelted into silicon-calcium-manganese deoxidizer to replace metal and other raw materials. Manganese and silicon calcium in existing production methods. Simplify the production process, thereby saving energy and reducing costs.

Silicon-calcium-manganese deoxidizer is mainly made of ore and iron filings rich in silicon, calcium, and manganese. It is smelted in a submerged arc furnace once to form a silicon-calcium-manganese deoxidizer. The process steps are: mechanically crush silica and other raw materials, remove impurities, wash the soil with water, mix evenly with coke powder, coal, and steel scraps, and send them to a submerged arc furnace for smelting. Ingredient content (weight) Silicon (Si). 20-55%, calcium (Al) 20-30%, manganese (Ba) 6-8% silicon calcium manganese deoxidizer.

The silicon-calcium-manganese deoxidizer has achieved a good deoxidation effect through the steelmaking deoxidation test. Since ores containing silicon, calcium, and manganese are directly used as raw materials, they can be smelted into products in a submerged arc furnace at one time, without smelting ores into products. Secondary smelting of metals and alloys has the defects of wasting labor and energy and low production efficiency. Therefore, compared with the existing production method, it not only reduces the smelting process but also has the advantages of a simple method and low energy consumption (production practice proves that the production of silicon-calcium-manganese deoxidizer per ton can save 1000 kWh of electricity), saving labor and low-cost professional.
