High Alumina Bricks Used In Blast Furnace High Refractoriness Alumina Fire Brick
High-Al Bricks Used in Blast Furnaces
High-Al Bricks Used in Blast Furnaces/High refractoriness /High refractoriness under load/Can resist the erosion of acid slag and alkaline slag/Good resistance to acid or alkaline slag
Summary:
High-Al Bricks Used in Blast Furnaces refers to the refractory products made with high bauxite clinker as the main raw material with Al2O3 content greater than 48% and used for masonry blast furnace.
Product features:
- 1. Refractoriness : the refractoriness of high aluminum brick is higher than that of clay brick and semi-silicon brick, up to 1750-1800℃
- 2. Refractoriness under load: because the aluminum oxide content in high aluminum brick products is high, less impurities, the formation of molten vitreous body is less, so the lotus soft temperature is high
- 3. Slag resistance: high aluminum brick aluminum oxide more, close to the neutral refractory material, can resist the erosion of acid slag and alkaline slag
- 4. Resistance to chemical erosion:high alumina refractory products have good resistance to acid or alkaline slag, metal liquid erosion, oxidation, and reduction reactions, and are strengthened with the increase of alumina content and the decrease of impurities
Range of application:
It can be used for various internal and external buildings of high-temperature furnaces, mainly for lining ironmaking blast furnaces.
