It has 1. high mechanical strength, long service life; 2. good chemical stability, no chemical reaction with materials; 3. good high temperature resistance, refractory ceramic ball maximum heat resistance temperature can reach 1900 degrees. It is especially suitable for high and low temperature converter, converter, hydrogenation converter, desulfurization tank and methanation furnace in chemical fertilizer plant. It can disperse gas and liquid, support, cover and protect catalyst. Refractory ceramic balls can also be used in hot blast stoves and heating conversion equipment in iron and steel industry.
Classification and application
Fire-resistant ceramic balls are divided into ordinary fireballs and high-alumina fireballs. The ordinary fireballs are suitable for converters and converters in sulphuric acid and fertilizer industries. The high-alumina fireballs are suitable for hot blast stoves and heating converters in urea, steel and other industries.
Precautions for use
At present, the main problems encountered in the use of fireproof balls are that high alumina fireproof balls are easy to crack and pit on the surface of the balls due to their high hardness and brittleness. As a result, the wear of the balls is very high. Nowadays, only polishing the balls before leaving the factory can be used to pick out the balls with high cracking or wear.
