Similar alumina bricks and more bricks clinker production process, except that the high proportion of clinker ingredients, can be as high as 90 to 95% clinker grading required before crushing and screening sorting iron, firing temperature higher when alumina brick tunnel kiln is generally 1500 ~ 1600 ℃. Practice has proved that high alumina clinker chosen before breaking strict grading and classification storage, combined with the use of bauxite and clay together fine grinding method, can improve product quality.
Use mainly for masonry blast furnace, hot stove, electric stove top, blast furnace, reflection furnace, rotary kiln lining. In addition, high alumina brick is also widely used open hearth regenerative checker bricks, pouring system with plug head, nozzle brick. But prices than brick high alumina brick, so with clay where you can meet the requirements without the use of high alumina bricks.
