Segment sand and fine powder are made of high-quality abrasive-grade bauxite as raw materials, with auxiliary materials, and refined in an electric arc furnace at a temperature above 2250ºC. They have the characteristics of high purity, good crystallization, high refractoriness, strong fluidity, low linear expansion coefficient, and corrosion resistance. It has been verified in practice that our company's products have the characteristics of no explosion, no pulverization, and no cracking during the application process, making them the best aggregate and filler for various refractory materials.
