customer's drawing
Definition:
White Corundum Mullite High Strength for Insulating corundum mullite brick also known as silicon insulation brick. Light refractories with silica content over 91% and bulk density below 1.2g/cm3. The refractoriness and load softening temperature are similar to those of common silica brick. However, due to many pores, the compressive strength, slag resistance and corrosion resistance are not as good as those of ordinary silica brick, while the thermal shock resistance is improved.
Using fine silica as raw material, the critical particle size is usually not more than 1mm, and the particle size less than 0.5mm is not less than 90%. A porous structure is formed by adding inflammable substances into the ingredients or gas generation method, and is made by firing. It can also be made into unburned products. It is mainly used in various parts of the kiln which require heat insulation or reduce the self weight without direct contact with the melt, without the action of aggressive gas and without the rapid change of temperature. When used at high temperature, it shall not contact with basic refractories. According to different materials, the maximum operating temperature is 1200-1550 ℃.
White Corundum Mullite High Strength for Insulating corundum mullite brick for use in applications from 1260°C to 1760°C.Each grade of brick is formulated to meet specific thermal and physical requirements.After firing each brick is machined to close dimensional tolerances.Insulating bricks are manufactured utilising exceptionally high purity clays and other ceramic materials.The carefully graded organics which are used during the manufacturing process burn out during firing to give a uniform pore structure.
Advantage:
(1) Refractoriness under load:
The refractoriness under load of White Corundum Mullite High Strength for Insulating corundum mullite brick is higher than that of clay brick and high aluminum brick, reaching 1640 ~ 1670℃, which belongs to advanced refractory materials.
(2) Thermal conductivity:
White Corundum Mullite High Strength for Insulating corundum mullite brick has better thermal conductivity than clay brick and high aluminum brick
Application:
Hot-blast furnace
Coke oven
Glass kiln
