Due to prolonged exposure to high temperatures, the areas directly in contact with flames in a kiln are usually the inner wall and bottom of the furnace. These two areas are exposed to high temperatures and chemical erosion for a long time, and are susceptible to erosion and corrosion from combustion materials, exhaust gases, and chemical reaction products. Therefore, when selecting refractory materials, refractory materials with high fire resistance, corrosion resistance, and wear resistance should be chosen.

The inner wall of the furnace is often affected by thermal shock, erosion, and ablation under the action of high-temperature gases and particulate matter. The acidic gases, alkaline gases, and particulate matter in high-temperature gases can cause chemical corrosion to refractory materials. Thermal shock and temperature changes can cause cracks and damage to the materials. Therefore, when selecting refractory materials, refractory materials with high temperature resistance and acid and alkali resistance should be selected. Due to the influence of thermal shock on the inner wall, refractory materials with low creep should be selected.

The bottom of the furnace is another area that is prone to erosion. The bottom bears the impact and thermal stress of combustion materials, and there is often unstable flame and temperature distribution at the bottom, which can lead to corrosion and damage of refractory materials. At the same time, due to the need for frequent material entry and exit, there will be wear at the bottom of the furnace. Therefore, when selecting refractory materials, they also need to have wear resistance, which can improve their service life. Reasonable selection of refractory materials can improve the service life of the kiln, and in order to meet the requirements of use, different parts should be selected according to the medium and temperature. Therefore, when selecting refractory materials, it is necessary to carry out reasonable design, so as to make the kiln work more stably and ensure the service life of our kiln.

When selecting refractory materials, it is necessary to make a reasonable selection based on the working environment of various parts of the high-temperature kiln, including temperature, medium composition, flow rate, and pressure parameters. At the same time, it is also necessary to consider the physical properties, chemical stability, and mechanical strength of refractory materials. Based on these properties, we can choose suitable refractory materials to ensure the long-term stable operation of the high-temperature kiln and improve its service life.
