The 55 content high alumina brick is a three stage high alumina refractory brick with an alumina content of 55%, and its fire resistance temperature is as high as 1770 degrees. Note that this temperature cannot be used as the use temperature.
High alumina refractory brick, an alumina silicate refractory material having an alumina content of 48% or more. It is formed by bauxite or other raw refractory materials with higher alumina content. High thermal stability, refractoriness above 1770 ℃. Good slag resistance.
What are the High Aluminum Bricks?
According to the aluminum content, it is usually divided into three categories: I, etc.: Al2O3 content & ge; 75-80%; II, etc.: Al2O3 content: 60% to 75%; III, etc.: Al2O3 content: 48% to 60%; In addition to the division, there are low creep high alumina bricks, anti stripping high alumina bricks, phosphate bonded refractory bricks and high alumina poly light insulation bricks.
What is Fire Resistance Temperature of 55 High Aluminum Brick?
The 55content high alumina refractory brick is a three stage high alumina brick with a fire resistant temperature of up to 1770 degrees. The use temperature is the load softening temperature in the physical and chemical index, up to 1420℃.
