High alumina mechanism refractory ball
Diameter size: φ50mm, φ60mm, φ80mm
High alumina mechanism refractory balls are made of industrial alumina and refractory kaolin as the main raw materials, through scientific formula molding and high temperature calcination. Chemical composition: The main component of high alumina refractory ball is alumina, and the content of alumina is different according different brands. For example, the content of alumina in high alumina low creep refractory balls such as RQA-55, RQA-65 RQA-75, RQA-80 is 55%, 65%, 75%, 80% respectively. Physical properties: particle size, bulk density, compressive strength, etc. The diameter of high alumina refractory ball is usually available in a variety of specifications such as φ5mm, φ60mm, φ80mm, etc. It has 1. High mechanical strength and long service life; 2. Good chemical stability does not react with materials; 3. Good high temperature resistance, the maximum heat resistance temperature of refractory balls can reach 1900 degrees. It is suitable for high and low temperature conversion furnaces, reforming furnaces, hydrogenation converters, desulfurization tanks and methanation furnaces in fertilizer, where it plays the role of dispersing gas and liquid, and supporting, covering and protecting catalysts. Refractory balls can also be used in hot blastoves and heating conversion equipment in the steel industry.
