0.8G High Alumina Insulating Brick Machine Pressed Refractory High Alumina Bricks High-Alumina Brick
Definition:
0.8G High Alumina Insulating Brick Machine Pressed Refractory High Alumina Bricks High-Alumina Brick generally refer to refractory bricks with a density less than 1.3 g/cm3. Due to the characteristics of low density, high porosity, small thermal conductivity, good thermal insulation and certain compressive strength, light-weight refractory bricks have been widely used in heat treatment equipment.
Super Heat Duty and
0.8G High Alumina Insulating Brick Machine Pressed Refractory High Alumina Bricks High-Alumina Brick are the products made from different fractions of refractory grog, fire clays and calcined bauxite of high purity. The different fractions of these raw materials are mixed in counter current mixers and plugged for obtaining homogeneous mixture. The mixture obtained hence, is then pressed in high capacity presses to give the desired shape and size. These pressed shapes are fired in high temperature tunnel kiln at 1300°C and above. These bricks are manufactured as per IS: 6 and IS: 8 specifications and high alumina in the range HEAT 5050 TO HEAT 88 in standard, arch and special shapes.
we provide these quality assured bricks to the clients at nominal rates.
For strength products, high-quality plate-like corundum and mullite are used as aggregates, sillimanite composite is used as a matrix, special additives and a small amount of rare earth oxides are mixed, and then subjected to high-pressure molding and high-temperature firing.
Advantage:
1. Low bulk density, low thermal conductivity, good thermal insulation performance.
2. Refractory category allow direct contact of fire, suitable ofr various atmosphere
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely
4. Product specification: standard form, normal standard, shaped and special shaped bricks.
5. Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the most widely used.
Application:
Insulating Fire Clay Brick Refractoryis not only widely used in insulating layers of various of thermal processing equipments, such as hot blast furnace, coke oven, glass kiln, etc, but also apply to linings in parts of furnace without strong high-temperature molten material erosive.
