Strenths of our product

Refining slag is supplied in three forms: premelting, sintering, composite, and electric fusion. To meet the needs of various steel development in different degrees, reasonable adjustment of physical and chemical indexes, so as to achieve the ideal purification effect of molten steel at a small cost. In the long term practice, the refining slag has the trinity function of desulfurization, deoxygenation and submerged arc to the molten steel, and does not produce the phenomenon of resulfur, so that the structure of steel products is stable and the quality of steel products is improved. Can be directly added to use, no residual impurities, reduce the refining power consumption. The slag washing effect is good, and the adsorption of inclusion is obvious.

Refining slag properties:

The main components of the refining slag are calcium aluminate, alumina, silicon oxide, calcium fluoride, magnesium oxide, etc., these metal ions combine into calcium oxide - calcium fluoride base, calcium oxide - alumina base, calcium oxide - alumina - silicon oxide base to form the composite material that is the refining slag. Refining slag is a necessary additive for deoxygenation and desulfurization in the refining process of iron and steel enterprises.

Refining slag features:

1. Reasonable chemical composition is conducive to slag formation as soon as possible and shorten smelting time.

2. Because of the fast slag formation, it can reduce the power consumption of the refining time.

3, reduce the consumption of ladle refractory material, improve the age of the ladle.

4. It has good desulfurization and deoxidation.

5, because of its low melting point, in the ladle blowing argon and electric furnace steel outlet process has a good adsorption of miscellany.

6, the composition is stable and uniform, and can be produced and packaged according to the requirements of users.

Refining slag has many advantages, such as uniform chemical composition, low melting point, fast melting speed, lower refining power consumption and shorter refining time, etc. It has been paid more and more attention by iron and steel enterprises and is one of the more important steelmaking additives at present.

The refining slag produced by our factory has no fluorine, hydrogen, nitrogen, carbon and other impurities, which is conducive to improving the quality of steel products; Without water absorption, it will not erode furnace lining and ladle. Compact structure, convenient for transportation and storage; The product itself is stable, fast slag, significantly reduce dust pollution from steel mills. The extensive use of refined slag makes steelmaking enterprises change the past refining process which relies on high alkali materials, slag and steel mixing, and desulfurization outside the furnace, which greatly improves the efficiency of steel production and improves the quality and performance of finished steel products.

Refining slag use:

The refining slag is put into the ladle before the steel is taken out, because the molten steel flows into the ladle from the high level, causing violent mixing between the molten steel and the refining slag, and the refining slag is quickly melted in the steel water, and then aggregates and floats. Because of its strong reducibility, the refining slag has a strong ability of deoxidizing and desulfurizing, which can remove oxygen and sulfur impurities in the molten steel during the mixing process. At present, the desulfurization capacity of the refining slag can reach more than 85%, which is a very special additive for steelmaking.

In addition, our company can also according to customer requirements customized production of various specifications, various indicators of metallurgical charge products
