Description for Mullite Insulation Brick: Mullite bricks are high alumina refractories with mullite as the main crystal phase. Generally, the alumina content is between 65% and 75%, and the refractory of mullite brick is relatively high, reaching above 1790 ℃. The starting temperature of load softening is 1600 ~ 1700 ℃. Good thermal shock resistance. There are two kinds of sintered mullite bricks and fused mullite bricks.Standard size 230 x 114 x 65 mm or according to customer requirements. Mullite Brick Type: jm23 brick, jm26 brick, jm28 brick, jm30brick, jm32 brick. Mullite Insulation Brick Features: 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.
Product Application
Applications For Mullite Insulating Brick: Mullite insulation brick mainly used for hot blast furnace top, blast furnace stack and bottom, glass furnace regenerator, ceramic sintering kiln, dead corner lining of petroleum cracking system,ethylene pyrolysis furnaces, tubular furnaces,reforming furnaces of synthetic ammonia,gas generators,linings or heat-insulating materials of the industries,etc.
