are made by placing the raw material solids into the molds of high pressure roller ball presses and extruding them under high pressure. They can be used as a substitute for ferrosilicon, and there is no dust pollution in the furnace. The reaction speed is fast and the cost is reduced. It is a kind of steelmaking process. new way. Silicon spheres can effectively reduce smelting costs. As a new type of metallurgical material, the price of silicon balls is lower than that of traditional metallurgical materials, but the effect it can achieve can reduce the cost of metallurgy. The low cost means that the reasonable application of silicon balls can increase profits. In addition, silicon balls can increase the furnace temperature, increase the fluidity of molten iron, effectively remove slag, and improve the toughness and cutting ability of pig iron and castings. At the same time, the particle size is uniform, fuel is saved during use, the melting speed is fast, the price is low, and the effect is good. It is a good substitute for ferrosilicon in smelting pig iron and ordinary casting.
