The chrome corundum brick is a corundum refractory brick containing Cr2O3. Since Cr2O3 forms a continuous solid solution with Al2O3, the high temperature performance of chrome corundum brick is better than that of pure corundum brick. The chrome corundum brick has good high temperature resistance and slag resistance, and its slag resistance increases with the increase of Cr2O3 content.
The chrome corundum bricks produced by sunrise Refractories are widely used in the following industries:
1. The lining material of the lower part of petrochemical industry slag oil and gas furnace.
2. not afraid of glass-colored glass melting furnace is subject to severe erosion.
3. sliding nozzle material.
4. Coal water slurry pressurized gasifier furnace lining.
The chrome corundum brick products produced by Zhengzhou sunrise refractory material are made of corundum and fused chromium oxide as the main raw materials, together with additives such as micro-powder, which are kneaded, formed and dried, and fired at a high temperature in a shuttle kiln. Chrome corundum brick products have the characteristics of wear resistance, thermal shock resistance and acid and alkali corrosion resistance. High-chromium bricks (Cr2O3≥90%) are mainly used in key parts of coal-fired chemical, chemical industry kiln, alkali-free glass fiber kiln, garbage incinerator, etc.; chrome corundum brick is mainly used in carbon black furnace and copper smelting furnace. The lining, the molten pool of the glass furnace, the slide of the rolling steel heating furnace, and the tapping platform. The dimensions, physical and chemical indicators and service life of chrome corundum brick products have reached or exceeded the level of similar products at home and abroad.
At the same time, sunrise refractory materials responded to market demand, and also developed high wear-resistant chrome corundum bricks, which are used as steel tapping bricks for steelmaking furnaces. They are mainly used in large-section steel billets, with large friction per unit area and high output. The heating furnace tapping groove not only can significantly extend the service life of the steel trough, reduce the time of mis-production, increase the output, reduce the consumption of refractory materials and maintenance costs, achieve obvious economic benefits, and the rapid cooling caused by shutdown maintenance The reduction in the number of times increases the overall life of the furnace. Reducing the number of shutdowns and repairs has become one of the means to increase production and improve economic efficiency in rolling mills of metallurgical enterprises.
