Low creep high alumina 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, molding and high-temperature calcination. Chemical composition: The main component of high-alumina refractory balls is alumina, and the content of alumina different according to different brands. For example, the content of alumina in high-alumina low-creep refractory balls with brands such as RQA-5, RQA-65, RQA-75, RQA-80 is 55%, 65%, 75%, 0% respectively. Physical properties: including particle size, bulk density, compressive strength, etc. The diameter of high-alumina refractory balls usually has φ8mm, φ25mm, φ40mm, φ50mm, φ60mm, φ80mm and other specifications. It has . High mechanical strength and long service life; 2. Good chemical stability, no chemical reaction with materials; 3. Good high-temperature resistance, the maximum resistance temperature of refractory balls can reach 1900 degrees. It is especially suitable for high and low temperature conversion furnaces, reforming furnaces,ation converters, desulfurization tanks and methanation furnaces in fertilizer plants, where it plays the role of dispersing gas and liquid, and supporting, and protecting catalysts. Refractory balls can also be used in hot blast stoves and heating conversion equipment in the steel industry
