Corundum Mullite Lightweight Brick

Corundum mullite bricks are made of high-purity corundum and high-quality mullite and are formed under high pressure. The thermal conductivity of refractory products is one of the important thermophysical properties of refractory materials. The thermal conductivity of corundum mullite bricks is 1.3. This product is an ideal material for building high-temperature and warm kilns, especially for high-temperature tunnel kilns. It can show high high-temperature structural strength, good volume stability, and good thermal shock stability, thereby extending the service life of the kiln. Lightweight corundum mullite bricks are made of white corundum, fused mullite, and burn-out agent in a certain proportion, mixed, formed, and fired at high temperature. The thermal conductivity of corundum mullite is the outstanding potential of corundum mullite.

 

Features: High temperature resistance, corrosion resistance, oxidation resistance, good thermal stability, small linear change rate, etc.

Uses: Widely used in various high-temperature kiln furnace linings and thermal insulation layers. Mainly used in petrochemical industry, large and medium-sized synthetic ammonia gasification furnaces and magnetic material gas furnace materials, high-temperature industrial kiln supporting facilities materials, high-temperature industrial kiln linings, kiln car bricks, push plates, furnaces, muffle linings, etc.

Low thermal conductivity: It has a good thermal insulation effect and can make the thickness of the furnace wall thinner.

Low heat capacity: Due to its light weight and low thermal conductivity, the lightweight mullite brick series products accumulate very little heat energy, and the energy-saving effect is very obvious in intermittent operation kilns.

It can be used as the lining of the kiln working surface that is in direct contact with the flame, which can significantly improve the energy-saving effect of the kiln.

Applied to smelting furnaces, firing kilns, flues, refining devices, heating devices, regeneration devices, gas generators and pipelines, soaking furnaces, annealing furnaces, reaction chambers and other similar industrial thermal equipment.

Lightweight corundum mullite bricks are made of white corundum, fused mullite, and burn-out agents mixed in a certain proportion, molded, and fired at high temperature. It has the characteristics of high temperature resistance, low thermal conductivity (good thermal insulation effect, can make the cellar wall thinner, and reduce the cost), high strength, and high thermal shock stability. It is widely used in various high-temperature cellar furnace linings and thermal insulation layers.

Corundum mullite polylight brick is a new type of high-efficiency and energy-saving refractory material that can directly contact the flame and has the characteristics of high temperature resistance, high thermal shock stability, high strength, and low thermal conductivity. It is widely used in ceramic roller kilns, shuttle kilns, cracking furnaces, hot air furnaces and various electric furnace linings, furnace door bricks, kiln car bricks, etc.

Low thermal conductivity, with good thermal insulation effect. 2. Low heat melting. Due to low thermal conductivity, mullite series lightweight insulation bricks accumulate very little heat energy, and the energy saving effect is obvious in intermittent operation. 3. Low impurity content has very low iron and alkali metal oxide content, so it has high refractoriness; the higher aluminum content enables it to maintain good performance in a reducing atmosphere. 4. High hot compressive strength. 5. Accurate appearance dimensions, speed up masonry, reduce the amount of refractory mud used, ensure the strength and stability of the masonry, and thus extend the life of the lining. 6. Can be processed into special shapes to reduce the number of bricks and masonry joints. Corundum mullite poly light bricks can be used as refractory lining or insulation layer of the hot surface working layer. Applied to: glass melting furnace upper structure material channel bricks, modification plates, processing kiln upper structure, E-glass melting furnace bricks. Firing kilns, smelting kilns, refining devices, heating devices, and other thermal equipment. Application areas: ceramic industry, glass industry, steel industry, petrochemical industry, aluminum industry, and other industrial fields.
