JM 23 Fireclay Insulation Brick is one kind of High-alumina refractory bricks.
One of the important working properties of High-alumina refractory bricks is the structural strength at high temperatures. The high-temperature creep properties are also measured to reflect the high-temperature structural strength. From the test, we knew that, with the increase of the Al2O3 content, the structural strength also become higher.
When the content of Al2O3 less than 70%, the load softening temperature depends on the quantity ratio between the mullite crystal phase and liquid phase. With the increase in the quantity of mullite, It also increased. Therefore, reducing the content of impurities in the raw materials is beneficial to improve the quality of the High alumina refractory bricks.
JM 23 Fireclay Insulation Brick refers to a heat-insulating refractory product made of bauxite with an Al2O3 content of not less than 48%.
Features:
1. Excellent strength at ambient and elevated temperatures.
2. High compressive strength.
3. Very low levels of iron and other impurities.
4. Lightweight and energy-efficient.
5. Lower heat storage than denser refractory.
6. Heats quickly and economically to operating temperature.
Application:
JM 23 Fireclay Insulation Brick are widely used in thermal
equipment in metallurgy, petrochemical, machinery, electric power,
building materials, aerospace, shipbuilding and other industrial
sectors.
