2.The Application of Ferro Silicon Powder

Composite deoxidizer is a very common deoxidizer in steel smelting, with its counterpart is a single deoxidizer, as the name implies, the composite deoxidizer is more than two deoxidizing elements, while a single deoxidizer only one deoxidizing element. More common composite deoxidizer is barium calcium silica-aluminum, calcium silica-aluminum, etc., not only use the affinity between silicon and oxygen, and aluminum, calcium, and other elements in the steel put into the liquid, more help to purify the steel. So what are the advantages of a composite deoxidizer compared with a single deoxidizer?

Compound deoxidizer can improve the deoxidizing ability of deoxidizing elements, so compound deoxidation is more complete than single deoxidation; deoxidizing elements with appropriate, conducive to the discharge of liquid deoxidation products, can reduce the content of inclusions in steel, improve the quality of steel; conducive to volatile elements small, solubility in steel, reduce the loss of elements, improve the deoxidizing efficiency of deoxidizing elements.

Compound deoxidizer is suitable for a wide range of steel, less dosage, the viscosity of the slag is small, easy to pour slag.

Compound deoxidizer is not only applicable to unrefined ordinary carbon steel, but also adapted to the refining of low-alloy steel, medium, and high carbon steel, and special alloy steel grades. At the same time, it can shorten the refining time and improve the hit rate and recovery rate of the alloy. Dosage is generally in 1.0-1.5kg/ton steel, the slag made thin, does not stain the ladle wall, easy to pour slag. Compound deoxidizer is low in price, easy to transport, does not absorb moisture, does not pulverize, no inventory of potential problems.
