Glass furnace lining mullite insulation brick 1700C insulating fire bricks Jm26 Jm28 Jm32 refractory brick
Product Description
Description of 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 sizing: 230 x 114 x 65 mm ,Special size and OEM Service also provide!
The size is precise, providing kinds of shapes according to customer's drawing
Feature of Mullite insulation brick :
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.
Applications of Mullite insulation brick :
1. Furnaces of metallurgy industry, heat treatment furnace
2. Furnaces of chemical industry and construction industry.
3. Furnace of incineration of garbage, recirculating fluidized bed furnace
4. 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.
