The main purpose of deoxidation in steelmaking is to remove oxygen from molten steel. This is because oxygen will have a certain impact on the quality of steel products. Deoxidation can improve the quality of steel, increase the production capacity, and promote the sustainable and development of steel plants. Multi-element compound deoxidizers often contains of more than 2 effective elements for deoxidation. Such as Aluminum, Barium, Silicon, Calcium, etc. Those compound deoxidizers are produced along with silicon slag or manganese slag, so they are much cheaper comparing to other ferroalloys,.

Ferro-silicon-aluminum alloy is a composite strong deoxidizer that can replace pure aluminum in steelmaking. The specific gravity of FeSiAl Alloy is 3.5-4.2g/cm³. As a result, this high density makes it easier to enter molten steel and has less internal burning loss. The use of Fe-Si-Al alloy can form low melting point inclusions, which are easy to float, and can improve the pouring performance of molten steel. In comparison, Ferro Silicon Aluminum Alloy has a better cost performance than pure aluminum.

Calcium silicon barium is an alloy containing barium element. It is a new and efficient deoxidizer and desulfurizer. Barium element can effectively reduce the vapor pressure of calcium and increase the solubility of calcium in molten steel during the steelmaking process. Compared with calcium silicon alloy, silicon barium calcium alloy can significantly improve the absorption efficiency of calcium element in liquid steel while deoxidizing.

Calcium silicon aluminum is an iron alloy containing silicon, aluminum and calcium elements. As a Multi-Element Compound Deoxidizer, CaSiAl alloy is suitable in electric furnace, converter, and medium frequency electric furnace smelting. On the other hand, it can replace ferro silicon, calcium silicon and other products, and better meet the needs of deoxidation, desulfurization and refining of molten steel. Calcium aluminium silicon alloy contains a variety of deoxidizing components, has a low melting point and fast diffusion. Its deoxidation effect is obvious, and it can also promote desulfurization and remove impurities. Its low price can significantly reduce the cost of furnace materials.

Silicon aluminum barium calcium high-efficiency deoxidizer is an auxiliary material for steelmaking. It is suitable for deoxidation of various forms of steelmaking, especially suitable for deoxidation of open-hearth converter steelmaking. During deoxidation, complex oxides containing calcium, barium, silicon, and aluminum are formed in the molten steel. These inclusions float up from the molten steel, reduce the gas in the molten steel, and purify the molten steel. Therefore, SiAlBaCa Alloy multi-element compound deoxidizer has strong deoxidation and desulfurization effects. It can well improve the flow performance of molten steel and solves the problem of nodules at the nozzle. In addition to its important deoxidation effect in steelmaking, calcium silicon aluminum barium also has important deoxidation and desulfurization effects in casting.
