what is the role of composite deoxidizer in steelmaking

Composite deoxidizer in steelmaking is a multi-element deoxidizer that contains many types of elements. After adding these elements to the molten steel, they do not introduce too many impurities into the molten steel and also help remove harmful impurities in the molten steel. The composite deoxidizer is also suitable for smelting in various furnaces and has good adaptability. A composite deoxidizer is different from a block deoxidizer. In addition to deoxidation, it can also effectively remove other impurities in molten steel.

As we all know, deoxidation is a relatively important process in steelmaking, and the quality of deoxidation is directly related to the quality of the steel. However, there are many types of deoxidizers and composite deoxidizers in the market used in steelmaking. Users can choose different deoxidizers depending on the degree of refining of different steels. However, if you want to achieve a good deoxidation effect, you need to pay attention to various points. Different deoxidation processes will also change the deoxidation efficiency, which will have an important impact on the quality of the molten steel.

The use of a composite deoxidizer as a deoxidizer in steelmaking has many features in the deoxidation process. A composite deoxidizer is used for deoxidation, and its resistance to deoxidation is very high, especially in severe post-blasting. The composite deoxidizer can be made as a powder or spheres with a size of 10-50mm. C and O react to form CO to stir molten steel, which has unprecedented kinetic reaction conditions compared to other deoxidizers, which promotes the aggregation, growth and floating of inclusions, purifies molten steel, and improves the fluidity of molten steel. A composite deoxidizer is used for pre-oxidation, which improves the alloy yield and reduces the cost of the alloy deoxidizer.
