1-5mm Black Silicon Carbide for Metallurgical Casting
Silicon carbide for casting is made from quartz sand mixed with petroleum coke or high-quality anthracite through high-temperature reaction. The crystal layer with about 90% SiC content becomes a high-quality silicon source and hot metal purifier in the cast iron process after crushing and sand making and moderate pickling. It is suitable for silicon addition, inoculation, deoxidation and purification in the production process of nodular iron and gray iron.
We can easily state with absolute certainty that for such high-quality at such price ranges we're the lowest around for Coal based carburizing agent, Asphalt Coke Carburizer, Carburizing Agent for Calcined Coke. The company has a strong science and technology team and scientific and technological innovation strength. We believe that we should actively introduce high-level talented people, and that the good use of intellectual capital is the key to corporate success. Our company adheres to the production concept of science and technology first and keeping improving.
Silicon carbide for casting Advantages
★ Prevent the precipitation of carbides and reduce chill tendency.
★ Improve the machinability and mechanical properties significantly.
★ Increase the fluidity, stabilize the composition of molten iron and prevent segregation.
★ Silicon carbide for casting can reduce the sensitivity of wall thickness and make the structure compact,the cutting surface is smooth.
★ Enhance the nucleation ability of graphite and increase graphite core.
★ For nodular cast iron, it is a strong deoxidizer ,it can reduce the amount of nodularizing agent and increase the nodularizing rate.
★ Reduce the cost of molten iron by reducing the rusted scrap and alloy.
★ Eliminate the oxidation factor of molten iron, reduce the oxidation of furnace wall and prolong the life of furnace wall by 30%.
★ Strong deoxidation, purifying molten iron, silicon content is equal to 75% ferrosilicon, but aluminum content is lower.

Application
The amount of silicon needed to be added in one heat of molten iron is calculated. The amount of silicon that can be absorbed by 1 kg of silicon carbide for casting in molten iron is 0.5-0.56 kg.
According to this calculation, it is easy to calculate the amount of silicon carbide to be added. If the process conditions permit, the hot metal can be absorbed better when it is overheated for 5 minutes at 1550 ℃.
The calculated and weighed silicon carbide is tied up with woven bags, put into the molten iron in the furnace, and the cover material is melted, only after adding the carburizing agent in sequence.
After years of development, our industry has developed and expanded, and the production of 1-5mm Black Silicon Carbide for Metallurgical Casting has completed the transition from small-scale to large-scale production, making it more competitive in the international market. When customers encounter problems, we promise to provide solutions quickly or send professional after-sales personnel to solve the problems properly for customers. We have adopted the international refined management mode and established a huge domestic and foreign procurement and sales network.
