High Alumina Bricks for the Arc Furnace Introduction
A neutral refractories with an alumina content of more than 48% are formed and calcined from bauxite or other material with high alumina content. High alumina refractory bricks for Arc furnace have high thermal stability, high alumina refractory bricks refractoriness above 1790 degrees Celsius. Refractroy bricks with good resistance to slag , used for lining of masonry furnaces, glass furnaces, cement rotary kiln.
High alumina refractory bricks are neutral refractories, which have strong resistance to acidic and alkaline slag, high refractoriness and high temperature mechanical strength are mainly used for the bottom of the soaking furnace, the lower furnace wall,continuous heating furnace wall,ceiling,hearth , burner brick and so on. Alumina refractory brick size can be customized according to customer requirement in RS Refractory material manufacturer.
High Alumina Bricks for Arc Furnace Feature
1. High Alumina Bricks for the Arc Furnace Refractoriness
The refractoriness of alumina fire bricks is higher than of clay bricks and silica bricks,which is as high as high 1750℃~1790℃, which is an advanced refractory material.
2. High Alumina Bricks for Arc Furnace Refractoriness Under Load
Due to the high Al2O3 content in high alumina refractory products and the low amount of impurities, the formation of friable glass bodies is less,so the load softening temperature is higher than the clay fire bricks .
3. High Alumina Bricks for Arc Furnace Slag Resistance Performance
High alumina refractory bricks contains high content Al2O3 and close to the neutral refractories, which can resist the erosion of acidic slag and alkaline slag ,because it contains SiO2, the ability of resistance to alkaline slag is weaker than the ability to resistance to alkaline slag is weaker than the ability to resist acidic slag.
