Composition and production process of silicon carbide balls

The main components of silicon carbon balls include silicon and carbon elements. The staff can finally obtain silicon carbon balls by pressing silicon carbide or silicon carbon powder into balls. Silicon carbon balls can reduce the cost of steelmaking and casting, and can achieve rapid deoxidation and promote the flow performance of molten iron, and finally achieve the effect of graphitization.

 Silicon carbon balls can be used as steelmaking additives, and the corresponding silicon carbon balls are placed in molten steel according to the standard. When a certain dissolution standard temperature is reached, the silicon carbon balls can be evenly melted in the molten steel, thereby producing a reaction. Among them, the silicon element reacts with the oxygen in the molten steel to produce silicon dioxide. This element does not damage the molten steel. Instead, it can make the oxides in the molten steel float on the surface of the molten steel, which is easier to be screened out, and finally achieves the improvement of molten steel. The purity and quality of the results. Silicon carbon balls can be used as inoculants and graphite improvers. After a certain proportion of silicon carbon balls are put in, the dissolution of silicon in the silicon carbon balls will produce an inoculation effect, which can greatly increase the number of crystal pellets, making cast iron The quality of the cast iron increases proportionally, and the addition of carbon can also promote the graphite ability in the casting process, reduce the whitening tendency of cast iron, and thus improve the flow performance of molten iron. The content of silicon carbon balls can be slightly adjusted. Compared with ferrosilicon, which is a ferroalloy, it is more flexible to use. The physical and chemical indicators can be adjusted according to the steelmaking requirements. In terms of particle size, silicon carbon balls are generally 10~50mm. Provides more convenience in terms of storage and storage.

In order to produce qualified silicon carbide balls, the adhesive is also an important part. The requirements for the adhesive in the production of silicon carbon balls: high strength, the ball forming rate is over 90%, and the strength after drying is over 80kg; content, requiring the adhesive to contain no or less inorganic components.
