What is aluminium brick

November 30, 2020

Alumina brick made by bauxite clinker and binder through Crushing,Mixing,Shaping,Drying and high temperature Sintering.Al2O3 content is 48%-80%,main mineral components are corundum and mullite phases.Refractoriness is above 1770°C,refractoriness under load is 1420-1550°C.Working temperature:1350°C -1650°C.

                                                                      Gongyi Hongda Furnace Charge Co., Ltd.

Alumina brick excellent strength at ambient and elevated temperatures.High compressive strength. Very low levels of iron and other impurities. Lightweight and energy-efficient. Lower heat storage than denser refractory.Heats quickly and economically to operating temperature.

High alumina brick is used in blast furnace, cupola, ladle, cement kiln, refining furnace and other equipment.
