Description
Chrome corundum bricks possess several characteristics, including high refractoriness, high strength, elevated refractoriness under load, and excellent thermal shock resistance. They also exhibit good corrosion resistance against steel slag, non-ferrous smelting slag, coal gasification slag, and various glass melts.
Features of Chrome Corundum Bricks:
- High bulk density, ensuring compactness and structural integrity.
- High softening temperature under load, maintaining strength at elevated temperatures.
- Good wear resistance, making them suitable for abrasive environments.
- Excellent thermal shock resistance, withstanding rapid temperature changes without damage.
Applications of Chrome Corundum Bricks:
- Chrome corundum refractory bricks are primarily used in refractory material linings within decomposing furnaces for the petroleum and chemical industries, as well as the chemical fertilizer industry.
- Fireproof chrome corundum bricks find application as high-temperature kiln linings and furniture in the metallurgical industry. They provide reliable performance in extreme temperature conditions.
