Injection Refractory Technology for Rotary Kiln Furnace Linings
Generally, the surface of a rotary kiln furnace lining must be kept at a certain temperature resisting wear and heat radiation. In order to maintain the necessary heat temperature, high-quality refractory materials are commonly used to form the furnace inlay. Refractory materials work as a heat resistant agent to help protect the rotary kiln. However, due to long-term tooling and high temperatures, degradation may occur, leading to high repair and maintenance costs. Injection refractory technology is an effective way to repair rotary kiln furnace linings when degradation occurs.
Injection refractory technology for rotary kiln furnace linings is a highly specialized process that requires advanced technology, precise measurements, and high-quality materials. Injection refractory technology includes drilling holes into the affected areas, mixing materials and injecting the refractory materials into the affected areas. The entire process lasts from four to ten hours and requires a minimum of two to four workers. The injection refractory technique is generally used for areas with a large amount of wear, such as the Hearth.
The injected refractory material is a combination of alumina and zirconia-aluminate, which are mixed and fired at a very high temperature. The combination of these two materials provides a strong bonding and heat resistant lining with excellent thermal shock resistance. The strong bond also helps to maintain the lining’s structural integrity, decreasing the repair and maintenance costs over time. After the refractory materials are injected, they are allowed to cool and cure for several hours before they are ready to be used.
Injection refractory technology can reduce wear and tear on rotary kiln furnace linings and improve their durability. The use of this technology is essential for improving the efficiency and longevity of rotary kiln furnace linings. It also helps to lower overall repair and maintenance costs, helping to reduce operating costs. With increased use of injection refractory technology for rotary kiln furnace linings, businesses can ensure more reliable and consistent operations.
