Compound deoxidizer is a very common deoxidizer. Compared with ordinary deoxidizer, the deoxidation effect of composite deoxidizer will be better. Composite deoxidizer refers to two or more deoxidizers, which can also improve steel.
Common silicon aluminum barium calcium, silicon calcium, silicon carbon alloy, etc., the method of use is to add the above composite deoxidizer to the molten steel at the beginning of steel tapping during the steel tapping process, mainly manually.
Composite deoxidizers usually use calcium, aluminum, magnesium, silicon and other elements for deoxidation, mainly due to the affinity of these elements with oxygen. Composite deoxidizers are generally used because some deoxidation products will also react with each other to produce some eutectics, further reduce the activity of oxidation products, and make the deoxidation reaction further proceed, that is, optimize the deoxidation effect.
Composite deoxidizer deoxidation can not only give full play to the deoxidation effect of strong deoxidizers, but also change the composition of deoxidation products, improve the fluidity of molten steel, and improve the purity of molten steel, and the use effect is remarkable. At the same time, the product not only has all the functions of previous deoxidizers, but also can be used in molten steel refining furnaces and secondary deep deoxidation, with significant effects, which can replace traditional high-cost calcium carbide deoxidation.
Different composite deoxidizers have different characteristics. When using, the deoxidizer should be selected according to the actual application situation to avoid bringing new impurities to the molten steel. You should know that some composite deoxidizers also contain impurity removal elements, such as aluminum composite deoxidizers, which can effectively purify impurities such as sulfur and phosphorus in molten steel, which is very helpful for the improvement of steel.
