In the high - temperature industrial sectors such as petrochemical, power, and steel, refractory materials play a crucial role. These materials are constantly challenged by extreme conditions, including high temperatures, chemical corrosion, and mechanical stress. Among them, refractory balls are widely used in high - temperature reactors. This article focuses on the performance of high - alumina refractory balls produced by Zhengzhou Rongsheng Refractory Materials Co., Ltd., providing in - depth insights through actual measurements and case studies.
In petrochemical high - temperature industrial processes, refractory materials face multiple technical challenges. High temperatures can cause thermal expansion and contraction, which may lead to cracking and spalling of refractory materials. Chemical substances in the reactor, such as acids, alkalis, and various corrosive gases, also pose a significant threat to the chemical stability of refractory materials. Therefore, refractory materials with excellent thermal stability and chemical resistance are urgently needed.
Zhengzhou Rongsheng's high - alumina refractory balls have outstanding physical and chemical properties. In terms of thermal conductivity, the measured thermal conductivity is as low as 0.8 W/(m·K) at 1000°C, which is significantly lower than the industry average of 1.2 W/(m·K). This low thermal conductivity helps reduce heat loss in the reactor, improving energy efficiency.
Regarding chemical resistance, the high - alumina refractory balls can withstand the corrosion of various chemical substances. For example, in a test with a strong acid environment (pH = 1), the mass loss rate of the refractory balls after 100 hours of immersion was less than 1%, indicating excellent chemical stability.
The excellent thermal stability of high - alumina refractory balls is mainly due to their unique crystal structure. The high - alumina content forms a stable crystal lattice, which can effectively resist the influence of high - temperature thermal stress. In terms of chemical resistance, the surface of the refractory balls forms a dense oxide film, which can prevent the penetration of chemical substances and protect the internal structure of the material.
Zhengzhou Rongsheng offers customized services according to customer needs. In terms of composition, the alumina content can be adjusted from 70% to 90% to meet different high - temperature and chemical environments. For size customization, the diameter of the refractory balls can range from 10mm to 100mm. In addition, the company also provides customized packaging services to ensure the safe transportation of products.
Zhengzhou Rongsheng has an extensive global service network, covering more than 50 countries and regions. Through this service network, the company can provide timely technical support and after - sales service to customers. For example, in a petrochemical project in the Middle East, the company provided on - site installation guidance and technical training, which was highly praised by the customer. According to customer feedback, the use of Zhengzhou Rongsheng's high - alumina refractory balls has significantly improved the stability of the reactor and reduced maintenance costs.
Petrochemical Industry: In a large - scale petrochemical reactor, Zhengzhou Rongsheng's high - alumina refractory balls were used. After one year of continuous operation, the reactor maintained stable performance. The low thermal conductivity of the refractory balls reduced the energy consumption of the reactor by 15%, and the high chemical resistance ensured that the reactor could operate normally in a complex chemical environment.
Power Industry: In a power plant's boiler, the use of these refractory balls improved the thermal efficiency of the boiler by 10%. The customized size of the refractory balls perfectly fit the boiler structure, and the long - term stable operation reduced the frequency of boiler maintenance.
Steel Industry: In a steelmaking furnace, the refractory balls with high thermal stability and chemical resistance effectively withstood the high - temperature and corrosive environment. The service life of the furnace lining was extended by 20%, reducing production costs.
Zhengzhou Rongsheng's high - alumina refractory balls have demonstrated excellent performance in terms of low thermal conductivity, high chemical resistance, and customization. Through a large number of industry application cases and customer feedback, it has been proven that these refractory balls can effectively improve the stability and efficiency of high - temperature equipment.
