Alloy Silicon carbide ball

The main components of silicon carbon spheres are: silicon and carbon elements, and silicon carbide or silicon carbon powder is pressed into balls, namely silicon carbon spheres. The emergence of silicon carbon balls reduces the cost of steelmaking and casting, and can achieve the effects of rapid deoxidation, promotion of molten iron flow and graphitization.

When used as a steelmaking additive, the corresponding silicon-carbon spheres are put into molten steel according to the standard. When the temperature reaches the dissolution standard, the silicon-carbon spheres are uniformly dissolved in the molten steel, and the silicon reacts with the oxygen in the molten steel to form carbon dioxide. Silicon, this element is harmless to molten steel, so that oxides in molten steel float on the surface of molten steel, which is easy to screen out, thereby improving the purity of molten steel and improving the quality of molten steel.

When used as an inoculant and a graphite improver, after a proportion of silicon-carbon spheres are placed in molten iron, the silicon element dissolves in the molten steel to produce an inoculation effect, which greatly increases the number of eutectic pellets, making the quality of cast iron increase proportionally, while carbon element At the same time, the addition of graphite can promote the graphite capacity in the casting process, improve the shape of graphite, and reduce the whitening tendency of cast iron, thereby improving the flow performance of molten iron.
