1,Description of Forsterite Brick:
Forsterite refractory brick is a weakly alkaline refractory developed in recent years. The main raw material is forsterite sand. In order to better improve the use effect of the product, a small amount of chromium oxide or zirconia is sometimes added. The product is high-temperature fired refractory brick, which has good high-temperature performance, especially good iron oxide corrosion resistance, good thermal shock stability and spalling resistance, Therefore, the product has been used in nonferrous metal smelting furnace, steel-making furnace, glass furnace, regenerator and other industrial furnaces with good effect. The shapes of the products are cylinder and brick walll.
