Product Description
Rongsheng Fire Resistant Lightweight Refractory Bricks High Alumina Insulation Brick
High Alumina Insulating Brick Description Light Weight High Alumina Brick, also known as high-aluminium heat insulating brick, Light weight high alumina bricks contain more than 48% alumina oxide. which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation. High Alumina Insulating Brick 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. 7.Low impurity content,and good thermal insulation performance.
