In steelmaking production, using aluminum for deoxidation can effectively reduce the oxygen content, minimize the bubbles generated by the carbon-oxygen reaction, and at the same time refine the grain structure of the steel, thereby improving the impact toughness of the steel and reducing the tendency of cold brittleness and aging. Since the specific gravity of aluminum (2.7g/cm) is much smaller than that of molten steel (7.6g/cm3) and steel slag (about 3.59/cm3), and it is extremely easy to oxidize in air and steel slag. Especially when used for deoxidation in converter steelmaking, aluminum floats on the surface of the molten steel, resulting in large burning losses and low yield. Therefore, in actual production, deoxidizers containing aluminum are often used for deoxidation. They have the characteristics of easily penetrating the steel slag layer, having a high melting point of about 1280℃, being difficult to melt in the steel slag layer, and being able to reach the deep layer of the molten steel for melting and deoxidation. Using them for the deoxidation and alloying of molten steel, their density is between that of molten steel and steel slag, which can effectively improve the utilization rate of aluminum. In addition to the low carbon content playing a good role in suppressing the carburization of molten steel, aluminum cakes are easy to store and can be added with a hopper, which not only simplifies the deoxidation and alloying process of molten steel but also reduces the labor intensity of workers.
Zhongshan Tefa Hardware Products Co., Ltd. produces and supplies a large amount of steelmaking deoxidation aluminum blocks:
1: The content of metallic aluminum can be selected and processed between 95% - 99.7%;
2: It melts quickly after being put into the molten steel, and the molten steel is evenly deoxidized under force;
3: It is not easy to float up after sinking into the molten steel, which shortens the deoxidation reaction time and improves the yield of metallic aluminum.
4: It is suitable for the ladle refining and molten steel purification of various steels.
