Characteristics of corundum mullite brick
Mullite is an excellent refractory material, which has the characteristics of uniform expansion, excellent thermal shock stability, high load softening point, low temperature creep value, high hardness and good chemical corrosion resistance. Pure electric fused mullite, ordinary fused mullite, all natural bauxite concentrate sintered mullite and light burned mullite. Lightweight mullite aggregates can be quickly oven-fired, and the exhaust gas is smoothly discharged at high altitudes, reducing the time of the oven and improving economic efficiency. The processing temperature is high, and it can be directly contacted with the flame working lining to complete the high temperature and energy saving. Low thermal conductivity, good heat preservation, special lightweight mullite aggregate, stable volume, high strength and good air tightness. The structural component is reduced by 40--60%, which reduces the problem of the top hanging bricks.
Sintered mullite is used to produce high temperature refractories. Mullite has only a stable binary compound under normal pressure. Natural mullite is very rare, and it is usually synthesized by sintering or electrofusion.
The use of lightweight mullite bricks in the kiln has the following advantages.
The mullite brick product has a low coefficient of thermal expansion, high thermal conductivity, good thermal shock resistance and high high temperature strength. It is not softened under long-term use at high temperature, is not attacked by any acid and alkali, has good salt resistance, is not wetted by metal and slag, and is light in weight. It is a high-quality high-temperature resistant material. The disadvantage is that it is easily oxidized at high temperatures and should not be used in an oxidizing atmosphere. Mullite brick products are widely used in lining of high temperature furnace lining (bottom, hearth, lower part of furnace body, etc.) and lining of smelting non-ferrous metal furnace. Mullite brick products can be used as reaction tanks and petrochemical autoclave linings. It can also be used to make bismuth copper with gold and light alloys.
Our factory has long-term supply of various types of various types of refractory bricks. If you are interested in our refractory bricks, please send us an email to get the latest quotation, and you are welcome to come to our company for field visits.
