Refractory bricks, also called fire bricks, can withstand high temperatures of 1580°C to 1770°C. They are mainly used for building smelting furnaces and are high-temperature building materials and structural materials for building kilns and various thermal equipment.
However, most of today’s kiln processes require frequent heating and cooling of the furnace, and the constant changes in temperature will cause the moisture in the refractory bricks to evaporate, the refractory brick wall shrinks, and the furnace lining will settle, crack, or even break, resulting in poor furnace insulation performance. Short life. The furnace wall structure built with refractory bricks makes it difficult to repair the furnace. Refractory bricks are demolished and rebuilt, the construction period is long, and the maintenance cost is high.
As a new type of environmentally friendly wall insulation material, the ceramic fiber module has extremely stable heat resistance and can be used in the range of -40°C to 1430°C. Excellent chemical stability such as acid, alkali and oil resistance. The characteristics of ceramic fiber modules are mainly reflected in the following aspects:
①Low heat capacity and low thermal conductivity.
②Excellent thermal stability, tensile strength and chemical stability.
③Good thermal stability and thermal shock resistance.
④ Noise reduction and sound absorption, uniform thickness, can be directly used for heat insulation in the kiln, easy to install and use.
According to the comprehensive comparison of several refractory materials, the ceramic fiber module insulation material stands out. Its safety factor is high, comprehensive performance and construction performance are ideal. It can be made into a module for installation, or as a spray coating. It can be economically formulated according to different medium temperatures. Reasonable thickness, high flexibility, and cost performance better than materials with the same performance.
