HIGH ALUMINA BRICK HA-SERIES

18 HA BRICKHIGH ALUMINA BRICK HA-SERIES

High Alumina Bricks, FB & HA – series are made from selected bauxite as main raw materials, fired at 1400 ~ 1470°C by advance process with stric quality control.

They have great features like high mechanical strength, high temperature stability, etc.

These bricks are usually used for hot face linings of Reheating furnaces, Incinerators, Boiler furnaces, and general industrial furnaces.
