Hanging roof tiles are generally made of mullite, so they are often called Mullite Hang Roof Bricks, or roof anchor bricks. The composition of mullite hanging bricks and mullite lightweight bricks is similar, and the general alumina content is between 65% and 75%. In addition to mullite, the mineral composition contains low alumina and a small amount of glass phase and cristobalite. Those with higher alumina content also contain a small amount of corundum.
Characteristics of Hang Roof Bricks
- Low thermal conductivity and good thermal insulation effect.
- Low heat capacity. RS insulation bricks store very little heat energy and have obvious energy-saving effects during intermittent operation.
- Low impurity content, with very low oxide content such as iron and alkali metals. Therefore, the refractoriness is high, and the high aluminum content allows it to maintain good performance under reducing atmosphere.
- High hot compressive strength.
- Standard appearance and dimensions. Speeding up the masonry construction and reducing the amount of refractory slurry ensures the strength and stability of the masonry.

Hang Roof Brick Mullite Uses
Various industrial kilns, such as bell furnaces, heating furnaces, cracking furnaces, heat treatment furnaces, shuttle kilns, tunnel kilns, roller kilns, enamel kilns, ceramic kiln roofs and walls, and thermal insulation lining materials.
Advantages of Tunnel Kiln Lightweight Mullite Brick Hang Roof Bricks
Tunnel kiln mullite Hang Roof, which includes multiple mullite groups. Each mullite set consists of two mullite Hang Roof Bricks, mullite T-shaped pendants, and metal hooks. The mullite T-shaped pendant as shown in the figure includes a plug-in board, a connecting block is provided on the plug-in board, and a metal hook is provided on the connecting block. Moreover, the mullite Hang Roof tiles are square in shape, and one side of the mullite Hang Roof Bricks is provided with a mullite T-shaped slot. Mullite T-shaped slots provided on the two mullite Hang Roof tiles of each group of mullite groups are respectively located at both ends of the insert plate. It has the advantages of lightweight, easy installation, disassembly and replacement, having good heat resistance, and the metal hook is not easy to be corroded and damaged.

Tunnel kiln mullite Hang Roof bricks are made of high-quality and high-purity refractory powder, and organic composite fillers are added according to the required proportion of the product. Lightweight mullite products are formed by vacuum extrusion and high-temperature sintering.
Advantages of tunnel kiln mullite Hang Roof Bricks: low thermal conductivity and low heat capacity. High purity and low impurity content. Resistant to high temperatures and can be in direct contact with flames. High strength and excellent thermal shock resistance. Can be cut at will.
Advantages of Kyanite Lightweight Mullite Refractory Bricks
As a raw material for refractory materials, kyanite has been used in a variety of products. The ideal chemical composition of kyanite is AL2O3·SiO2, which is a homogeneous multi-phase variant with the same composition as andalusite and sillimanite. Kyanite is denser than andalusite and sillimanite. This high density is in a metastable state under normal pressure and can spontaneously decompose into a low-density mineral combination, namely mullite-quartz, at a certain temperature.
Lightweight mullite bricks are used for high-temperature kiln linings that are not in contact with the melt. Not only high operating temperature is required, but also low thermal conductivity is required. For general lightweight refractory materials, they are not only required to have a high operating temperature but also need to have a low thermal conductivity. For lightweight refractory materials, the smaller the gap size within a certain range, the lower the thermal conductivity. Therefore, the micropores formed by the decomposition and expansion of kyanite are favorable conditions for improving the thermal insulation performance of lightweight mullite bricks.
Lightweight mullite refractory bricks have the characteristics of high operating temperature, low heat capacity, low thermal conductivity, high strength, and good thermal shock resistance. The AL2O3 content of lightweight mullite bricks synthesized from kyanite and industrial alumina powder is 67.1%, which is significantly higher than that in foreign countries.
