High Alumina Refractory Bricks Introduction:
We bring forth high quality High Alumina Bricks, which is manufactured to meet the requirements of neutral refractoriness where safe working temperature is more than 1500 degree centigrade. We offer High Alumina Bricks in different specifications as per customer requirements. High alumina brick is one kind of neutral refractory material, not only has certain corrosion resistance to acidic and alkaline slag, but also has the characteristics of high cold crushing strength, erosion resistance, strong penetration resistance, and high refractoriness under load.
Features Of High Alumina Refractory Bricks:
1.Excellent strength at ambient and elevated temperatures.
2.High compressive strength.
3.Very low levels of iron and other impurities.
4.Lightweight and energy-efficient.
5.Lower heat storage than denser refractory.
6.Heats quickly and economically to operating temperature.
