Fused calcium aluminate

[Product Specifications]: A, B, C

[Production capacity]: 30,000 tons / year

[Application]: Suitable for ordinary carbon steel, high carbon steel, high and low alloy steel.

【product description】:

Fused calcium aluminate is also called pre-melted refining slag or pre-melted aluminum-calcium slag, which has been maturely applied abroad, such as developed countries such as South Korea, Japan, Europe and the United States. The fused calcium aluminate produced by Ruishi Company has a uniform chemical composition, a low melting point, and a fast melting speed, which can shorten the smelting time. It does not contain fluorine and does not attack the furnace lining and ladle. , Fast slag formation, can reduce dust pollution to steel plants, comprehensively stabilize the refining process; does not contain hydrogen, nitrogen, carbon and other impurities, which is conducive to improving the quality of steel. It has been confirmed by the user that the curve function of the stability of the fused calcium aluminate products of our factory with time almost forms a straight line. It avoids many unsuitable phenomena brought to metallurgical production by the wavy and zigzag curve functions of middle and low-grade products (sintered products, cupola raw products).
In addition, we can organize mass production according to the chemical composition required by users and keep them confidential.
[Instructions]
When deoxidation is the main method, the bottom of the package is added directly before tapping; the amount is determined by the carbon content of the final molten steel, and it is usually added at 4-6kg / 1000kg steel; Ferrosilicon and aluminum; After the steel is tapped, the carbon structural steel is conventionally added with manganese and ferrosilicon, without adding other alloys and aluminum feed lines. The molten steel in the package only needs to be blown with argon for refining; using this product, the amount of decarburizer and silicon carbide (silicon carbide) is used. Can be reduced by 30-50%
When desulfurization is mainly used, the bottom of the bottom of the package is added in a good amount of 1/3, but it must be added to the impact position of the bottom of the steel flow; as the molten steel flows out, add 2/3 of the amount; the amount of 6-8kg / 1000kg of steel, depending on The original sulfur content of molten steel and the use effect are determined.
