Abstract

The invention discloses a low-heat-conduction multi-layer mullite brick and a preparation method thereof. Mullite with low heat conduction coefficient is utilized as a main raw material, a small amount of silicon carbide is added, a novel binding agent is utilized to replace clay, and a multi-layer composite structure is adopted. The heat conduction coefficient of a product is far lower than that of like products, thermal shock resistance and corrosion resistance of the product are greatly improved by means of excellent high temperature performance of the mullite, the service life of the product is prolonged, and simultaneously the energy-saving and consumption-reducing effect is obvious.

Description

technical field The invention relates to the technical field of refractory and environment-friendly materials, in particular to a low thermal conductivity multilayer composite mullite brick and a preparation method thereof. Background technique The upper and lower transition zones of the new dry-process cement rotary kiln are adjacent to the firing zone, and are often subjected to a harsher operating environment than the firing zone. Bricks are lining bricks. At present, most of the silica bricks sold in the market use first-grade or super-grade bauxite, and some companies also add fused corundum to improve the high-temperature performance and corrosion resistance of the product, but this also increases the thermal conductivity of silica bricks. The increase of the height makes the heat loss in the cement kiln faster, the fuel consumption per ton of cement increases, and the cylinder temperature rises, which easily deforms the cylinder and shortens the service life of the ...
