Refractory fireclay brick refers to fire brick containing Al2O3 less than 48%, which is made of high grade bauxite through high temperature calcinations. High alumina brick is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. It has characteristic of high refractoriness under load, which decide high alumina brick is a n ideal material for various kinds of industrial furnace. It is widely used in building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.
characteristics: 1 Excellent thermal stability 2 High refractoriness under load 3 Chemical stability and anti-corrision 4 Small high temperature creep rate 5 Excellent thermal shock resistance
Typical Application: 1 Building materials for blast furnace 2 Building materials for hot-blast stove 3 Building materials for coke oven 4 Building materials for steel making furnace 5.Building materials for wood oven 6 Kiln car building 7 For ladle and refining furnace 8. For aod furnace 9. For pizza oven building.
