Brown jade, common name is also known as diamond sand, is a brown man creted with alumina, carbon material, and three raw materials that melt and reduced in the electric arc furnace, so it is this name. The main chemical ingredients of the brown jade are Al2O3, and its content is 95.00% -97.00%, and there is another small amount of Fe, Si, Ti, etc. The brown jade is the most basic abrasive, because its grinding performance is good, wide application range, is cheap, and is widely used.
The brown jade is the main raw material with aluminum aluminous, coke (anthracite), and has a high temperature smelting in the electric arc furnace. It is suitable for grinding high metal, such as various general steel. , Can forged cast iron, hard bronze, etc., can also manufacture advanced refractories. The brown grungy has the characteristics of high purity, good crystallization, strong fluidity, low wire expansion coefficient, and corrosion resistance. With dozens of fire-resistant manufacturers, the product has the characteristics of explosion, no powdering, and non-cracking in the application. In particular, it is much higher than the cost-effectiveness of traditional brown jasteas, which makes it a best aggregate and filler of brown jade refractory materials.
