65% Al2O3 High Alumina Refractory Bricks Erosion Resistance Alumina Firebrick
High Aluminum Bricks for Hot Blast Furnace
High Aluminum Bricks for Hot Blast Furnace/Excellent fire resistance/Strong erosion resistance/Can withstand the test of many high temperature cycles
Summary:
High Aluminum Bricks For Hot Blast Furnace refers to the use of high bauxite clinker or silica line stone mineral with part of the clay made of refractory brick, used for masonry hot air furnace refractory products. Hot blast furnace is a huge brick structure built entirely of refractory materials to provide equipment for hot blast furnace for blast furnace smelting. The internal masonry is subjected to high temperature and its own load for years, and is eroded by the various oxide dust in the gas.
Product features:
- 1. Excellent fire resistance
- 2. Strong erosion resistance: high aluminum brick has excellent erosion resistance, can well resist chemical corrosion and physical erosion
- 3. Long life: high aluminum bricks have a longer life span,can withstand the test of many high temperature cycles. Therefore, the choice of high aluminum brick to make the lining of the hot air furnace can greatly extend the service life of the equipment, reduce the number and cost of replacement and maintenance
Range of application:
High aluminum brick is usually used in the heat exchanger, combustion chamber, slag mouth and other parts of the hot blast furnace, which can ensure the wear resistance and mechanical strength in the high temperature environment
