As a kind of high quality refractory bricks, Tabular alumina brick can be the great refractory materials applied in many high temperature industries for resisting all kinds of
The fourth part (pp. 595 to 656) is devoted to high-alumina and zirconia -containing materials and processes, including fused brick,e.g., Corhart (mullite), and Mono- frax ( corundum ), used for glass-tank furnaces.
Oct 24, 2009 · The furnace consists of a water cooled steel shell and 3-20 tonne batches of material are fused at any one time. The fused alumina has a high density, low porosity, low permeability and high
You can also choose from angle bricks, thin bricks. As well as from concrete bricks, shale bricks, and clay bricks. And whether sintering brick is steam-cured, sintered, or autoclaved. There are 8,634 sintering brick suppliers, mainly located in Asia. The top supplying country is China, which supply of sintering brick respectively.
High alumina fireclay Brick for Heating Furnace is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life.
It is divided into two kinds - corundum bricks and fused corundum brick. Respectively Sintered alumina and fused corundum as raw material. Corundum Brick Advantages. 1.high density& temperature resistibility. 2. low bulk density, high compressive strength. 3. resistance to high temperature(≥1790℃). 4.good thermal shocking resistance.

CUNSE zircon corundum brick is made of a-Al2O3, ZrO2 and zirconium corundum clinker as materials, it is produced by mixing, molding, drying and sintering at high temperature in shuttle kiln. Features: 1. Dense crystal structure. 2. High bulk density. 3. High mechanical strength at normal and high temperature. 4. Good thermal shock resistance. 5.
Refractory brick is a refractory material for lining masonry of high temperature kiln. The bulk density of refractory brick is also called refractory brick density. It is one of the important testing items in the physical and chemical indicators of refractory brick. The volume density index of refractory brick is the volume of stomata in the product.

Chrome corundum brick is made of corundum and fused chromium oxide as the raw material, mixed with micro powder and other additive, and then through mixing, shaping, drying, sintering in the high temperature shuttle kiln. chrome corundum block is widely used for linings of high temperature furnaces or kilns in many industries of steel, building material, non-ferrous smelt, light industry and chemical industry.
The high - temperature stabilized crystal phase with high content of Al2O3 is more than 71.8%. With the increase of 71.8%, the amount of corundum is increased and the mullite is reduced, and the high temperature performance of high alumina refractory bricks is improved accordingly.
The furnace throat is a part of the direct impact and friction when the burden drops, and the high density and high alumina brick is usually adopted. The upper and middle shaft temperature is only 400~800 degrees, the parts with high alumina brick and sillimanite brick.

Corundum bricks of ≥ 90% Al2O3 are manufactured using synthetic fused corundum and sintered corundum and finely grained highly aluminous raw materials with ceramic and chemical bonding. Sophisticated bricks and large blocks with 65 % to 99 % Al2O3 content are shaped by vibration shaping or slip casting and fired at high temperatures in modern firing plants, apart from compression shaping on modern hydraulic presses.
Refractory High-pure zircon bricks Pure zircon brick is a zircon-based crystal phase, referred to as high zirconium brick, and is one of the important types of zirconium-containing refractories. 1. Production of pure zircon bricks (1) Raw material processing. The raw material of the zircon brick is a selected zircon ore, referred to as zircon sand.
The sintering parameters, spalling resistance and corrosion against soda lime glass melt of such bricks were also determined. The results indicated that mullite, corundum and monoclinic zirconia represent the main mineral constituent of the fired bricks.
Sintered corundum mullite bricks are produced by sintering of high purity fused corundum, synthetic mullite and chromium oxide. Sintered corundum mullite bricks have high bulk density, high compressive strength, good thermal shocking resistance, and good corrosion resistances to acids and alkali. They are not influenced by H2, CO gases at use.
