Standard sizing:This brick is special size for pipes of industry furance ,Special size and OEM Service also provide!
The size is precise, providing kinds of shapes according to customer's drawing
Definition:
Aluminum Silicate 1150C 1250C White Corundum Mullite High Strength for Insulating corundum mullite 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.
Aluminum Silicate 1150C 1250C White Corundum Mullite High Strength for Insulating corundum mullite brick containing Al2O3 30%~46% lightweight refractory products, chamotte or light clinker and plastic clay as main material, usually can be the combustible material production and formation of multihollow structure by chemical method or foam method. The bulk density of the commonly used lightweight clay brick is 0.75~1.20g/cm3, the compressive strength is 2.0~5.9Mpa, the thermal conductivity is 0.221~0.442W/m.k (1350°C ).
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. It has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance.
2. It has the lowest and most stable thermal conductivity in various insulating refractory bricks
3. It can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.
Application:
Aluminum Silicate 1150C 1250C White Corundum Mullite High Strength for Insulating corundum mullite brick is widely used as a primary hot face refractory lining or as back-up insulation behind other refractories in furnace(such as carbon furnace,cracking furnace,heating furnace for oil refining,roller kiln, tunnel kiln.),flues, flues,refining vessels, heaters,regenerators and similar high temperature industrial equipment.
