Applications:
Super Dense Fireclay Brick used for lining blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kilns. In addition, high alumina bricks are also widely used as open hearth regenerative checker bricks, plugs for pouring systems, nozzle bricks, etc.
However, the price of high alumina bricks is higher than that of Super Dense Fireclay Brick, so it is not necessary to use high alumina bricks where Super Dense Fireclay Brickcan meet the requirements.
