Overview of Mullite insulation bricks

Mullite insulation bricks are a type of high-alumina refractory material with mullite as the main crystal phase. The bulk density of this lightweight insulation brick ranges from 0.60 to 1.25 grams per cubic centimeter. Its working temperature range is between 1300°C and 1600°C. The refractoriness of mullite insulation bricks is relatively high, reaching above 1790°C. The softening onset temperature is between 1600 and 1700°C. It has good thermal shock resistance, insulation and heat preservation performance, and structural strength. It is an ideal insulation choice for industrial kilns, thermal equipment and other high-temperature environments.

technical parameters Mullite insulation bricks

Mullite insulating bricks are energy-efficient refractory materials primarily composedof mullite, manufactured using high-purity raw materials and unique processes.This material exhibits outstanding high-temperature volume stability, thermal shockresistance, and mechanical strength, while also featuring low thermal conductivity.

Features of Mullite insulation bricks

Excellent high-temperature performance

It has a high operating temperature, usually ranging from 1300℃ to 1600℃, and can even reach above 1700℃. It is an ideal material for the inner lining of high-temperature kilns.

Good heat preservation effect and significant energy saving: The interior has a porous structure, with a low thermal conductivity, which can effectively reduce heat loss and significantly decrease fuel or power consumption.

Lightweight and low in density: It is a lightweight refractory material, with a volume density usually ranging from 0.6g/cm³ to 1.25g/cm³. This can significantly reduce the overall structural load of the kiln, lower the cost of steel structures and foundation construction.

Good thermal stability: It can withstand sharp temperature changes without cracking or peeling, and has a long service life.

applications Mullite insulation bricks

1. Metallurgical industry This is one of the largest application fields of mullite insulation bricks. Insulation layers for various industrial kilns and furnaces: such as steel rolling heating furnaces, annealing furnaces, heat treatment furnaces, tempering furnaces, forging furnaces, etc. They are constructed on the outside of the refractory working layer of the furnace body (such as corundum bricks, high alumina bricks), effectively reducing heat loss of the furnace and saving energy and reducing consumption. Non-ferrous metal smelting furnace: It serves as an insulation layer on the furnace walls and roof of furnaces for melting aluminum, copper, zinc, etc. Iron smelting system: The roof and wall insulation of the hot blast stove, the heat-insulating lining of the torpedo tank truck, etc.

2. Ceramics and Building Materials Industry Ceramic kilns: Especially tunnel kilns, belt kilns, and shuttle kilns that require extremely high uniformity of temperature. Mordorite insulation bricks are used as insulation materials for the kiln car platform, the side walls and top of the kiln body, which can effectively ensure the stability of the kiln temperature and improve the firing quality of ceramic products. Glass melting furnace: It is used for heat preservation at the bottom of the pool, insulation of the side walls, and heat preservation at the top of the furnace, reducing the heat loss of the molten glass and stabilizing the melting process. Cement rotary kiln: It is used as an insulation lining in areas with relatively low temperatures such as preheaters, decomposition furnaces, and the cooling sections of the rotary kiln.

3. Petrochemical Industry Large-scale tubular furnaces such as ethylene cracking furnaces, hydrogen production conversion furnaces, and reforming furnaces. These furnaces operate at extremely high temperatures (usually above 1000℃), and have extremely strict requirements for the heat resistance and stability of the refractory materials. Mordorite insulation bricks are the core material of the insulation layer of the furnace walls in these devices. Backfill insulation for high-temperature reaction equipment such as gasifiers and carbon black reactors.

4. Machinery and Heat Treatment Industry Various furnace linings for resistance furnaces, conveyor furnaces, and pit furnaces. Boiler: It is used as a refractory insulation layer in the furnace, flue and other parts of large-scale power station boilers or industrial boilers.

5. Other high-temperature fields Waste incinerator: As a heat insulation layer in the combustion chamber and flue, it resists corrosive atmospheres. The construction of the furnace bodies for small thermal equipment such as laboratory high-temperature electric furnaces and muffle furnaces.
