High alumina brick

Description:

High alumina brick is a kind of refractory material, and its main component is Al2O3. Due to different resource reserves, national standards are not completely consistent. For example, in Europe, the lower limit of Al2O3 content of high alumina refractories is 42%. In China, the Al2O3 content in high alumina bricks is usually divided into three grades: I, etc. - Al2O3 content > 75%; II, etc. - Al2O3 content is 60 ~ 75%; III, etc. - Al2O3 content is 48 ~ 60%.

Advantages:

High refractoriness, high refractoriness under load, resistant to slag erosion

Application:

Blast furnace, hot blast stove, reverberatory furnace, electric furnace roof, rotary kiln, regenerative chamber checker brick, chock plug, nozzle brick
