The chemical composition is uniform, the melting point is low, the melting speed is fast, and the smelting time can be shortened. No fluorine, no erosion furnace lining and ladle;
Free of hydrogen, nitrogen, carbon and other impurities, it is beneficial to improve the quality of steel.
In the case of deoxygenation, it is directly added to the bottom of the bag.The amount of the added weight is determined by the carbon content of the finished steel water, and is generally used for the combination of 4-6kg/1000kg steel.In the first quarter of the steel, the regular added manganese iron, silicon iron, aluminum;After the steel is added to the steel, the steel will be added to manganese and silicon iron, without adding other alloy and aluminum feed line. Using the product to deoxidize, the amount of carbon added (silicon carbide) can be reduced by 30-50%.
In the case of desulphurization, the amount of added in advance use is 1/3, but it must be added to the impact position of bottom steel flow.As the molten steel flows out, the side joins 2/3.Using 6-8kg/1000kg steel, the original sulfur content and the use effect of steel water are determined.
It is mainly used in LF furnace, open hearth furnace, converter ladle refining, remove impurity such as sulfur, oxygen in molten steel, reduce the harmful elements in the steel and the content of impurities, suitable for carbon steel, high carbon steel, high, low alloy steel.
