Method for producing smelting flux by using manganese-containing melt

[0034] In the traditional blast furnace ironmaking process, the manganese-containing by-product melt samples at the temperature in the blast furnace are collected, and the manganese content is measured to be 18%. 800 kg of the manganese-containing by-product melt (1300°C) produced during the blast furnace smelting process is required, and a diameter of 1.7 The flux furnace with a height of 1.5 meters collects the manganese-containing melt and keeps it warm for 20 minutes, then adds 25 kg of manganese at 40°C to adjust the manganese content of the manganese-containing melt to 21%.

[0035] Then add 100 kg of magnesium at 95°C, 100 kg of silicon at 97°C, and 60 kg of fluorite at 80°C and keep it warm for 2 hours, then raise the temperature of the flux furnace to 1700°C by arc heating, melt for 30 minutes, and finally take off the furnace and quench in water The finished product is obtained; the labor intensity of workers is reduced by two-thirds, and consumable materials are save...

[0037] In the process of electric furnace silicon smelting, samples of molten manganese-containing by-products in the blast furnace are collected, and the manganese content is measured to be 20%. 800 kg of manganese-containing by-product melt (1300°C) produced during the blast furnace smelting process is required, and the diameter is 1.7 meters. , The flux furnace with a height of 1.5 meters collects the manganese-containing melt and keeps it warm for 20 minutes, and then adds 25 kg of manganese at 50°C to adjust the manganese content of the manganese-containing melt to 23%.

[0038] Then add 80 kg of magnesium at 98°C, 100 kg of silicon at 97°C, and 70 kg of fluorite at 85°C and keep it warm for 1 hour, then raise the temperature of the flux furnace to 1750°C by arc heating, melt for 30 minutes, and finally take off the furnace and quench in water That is the finished product.

[0040] In the process of traditional blast furnace manganese smelting, samples of molten manganese-containing by-products in the blast furnace are collected, and its manganese content is measured to be 25%. 800 kg of manganese-containing by-product melt (1300°C) produced during the blast furnace smelting process is required, and a diameter of 1.7 The flux furnace with a height of 1.5 meters collects the manganese-containing melt and keeps it warm for 20 minutes, then adds 20 kg of manganese at 50°C to adjust the manganese content of the manganese-containing melt to 27%.

[0041] Then add 80 kg of magnesium at 90°C, 100 kg of silicon at 100°C, and 80 kg of fluorite at 75°C and keep it warm for 2 hours, then raise the temperature of the flux furnace to 1600°C by arc heating, melt for 30 minutes, and finally take off the furnace and quench in water That is the finished product.
