Product Description Product DescriptionRefractory ball is a refractory material with a very wide range of applications. Refractory porcelain balls are made of industrial alumina and refractory kaolin as the main raw materials, through scientific formula, shaping and high-temperature calcination. Refractory ceramic balls are fillers used in ammonia synthesis, methanol shift furnaces, sulfuric acid converters and smelting high-temperature converters. They have the characteristics of high aluminum content, temperature resistance, and pressure resistance. Their diameters range from 15φmm to 70φmm. Among them, the heat storage ball is also a kind of refractory ball. The heat storage ball is also called a spherical heat storage body. The spherical heat storage body has the advantages of good thermal shock stability, large heat storage, high strength, easy cleaning, and reusability. It is suitable for Selection of regenerative ball combustion systems for gas and non-gas fuel industrial furnaces.Product ParametersRefractory balls have high mechanical strength, long service life, good high temperature resistance, oxidation resistance, wear resistance, resistance to strong acid and alkali chemical corrosion, good chemical stability, no chemical reaction with materials, excellent resistance to rapid cooling and rapid heating, and Low chemical activity.Fire-resistant ball classification:1. Classified by aluminum content Ordinary refractory balls: suitable for converters and conversion furnaces in the sulfuric acid and fertilizer industries. High-aluminum refractory balls: High-aluminum refractory balls are suitable for hot blast furnaces, heating conversion furnaces and other equipment in urea, steel and other industries.2. Classification by type Refractory ball: aluminum content 45-90, silicon content 10-70, iron content ≤1. Corundum refractory ball: aluminum content 90-98, silicon content 0.5-5.0, iron content ≤ 0.5. Low silicon refractory ball: aluminum content 90-98, silicon content ≤ 0.3, iron content ≤ 1.
