Calcium silicon aluminum barium for steelmaking

Thread Content

Calcium silicon-aluminum barium is a good deoxidizer. As a new type of composite metallurgical material, it is widely used in the metallurgical industry. Calcium silicon-aluminum barium is an ideal replacement for deoxidizers and desulfurizers. Calcium silicon-aluminum barium is a common steelmaking deoxidizer. When used, it can not only reduce the oxygen content of steel, but also remove impurities such as sulfur and phosphorus in steel, which has the effect of purifying molten steel and improving the quality of steel. The production process of silicon aluminum barium calcium is also very simple. Silica, bauxite, and coke are mixed evenly, and then added to the submerged arc furnace for smelting to produce silicon aluminum alloy. Then add CaO and coke in batches to promote the formation of calcium silicon aluminum. Then add barium ore and coke in batches to promote the formation of calcium silicon barium aluminum alloy. Through the reasonable application of silicon aluminum barium calcium, the intrinsic quality of molten steel can be improved and the fluidity of molten steel can be improved. Improve the alloy yield, Si-Fe yield increases by 10-15%, and the effect is stable. The dosage is 0.6-1.5kg/ton of steel. After oxygen blowing for ordinary carbon steel, the oxygen content in the molten steel is as low as 80PPM. Increasing the dosage and improving the lining can further reduce the oxygen content in the molten steel. While deoxidation is completed, there is still 10-30% desulfurization capacity. Add Baoding directly before tapping, usually at 0.6-1.5kg/ton of steel. When 1/4 of the steel is tapped, ferromanganese and ferrosilicon are added as usual. After tapping, ferromanganese is added to the carbon steel as usual, and other alloys do not need to be added. Aluminum, feed wires, and molten steel in the ladle only need to be refined by blowing nitrogen. However, you also need to pay attention to the use of silicon aluminum barium calcium. If you do not follow the correct process, not only will you not achieve a good deoxidation effect, but it will also cause certain damage to the quality of the steel. Therefore, when using calcium silicon, aluminum, and barium in steelmaking, you must pay attention to the correct process.
