Description

The AL203 content of high alumina bricks depends on the composition of high bauxite clinker in the selection of high bauxite clinker should be selected (1) Sintered well, the organization is generally uniform and dense, and there are rough and loose material blocks. The fracture is mostly white and light yellow. The thickness of impurities such as iron and calcium on the surface shall not exceed 0.5mm, the area shall not exceed 20% of the total area of the material block, and the erosion depth of the low melt shall not exceed 5mm. (2) Clinker shall not contain wood blocks, pebbles, and other impurities.

In high alumina brick products, when the temperature of refractory brick changes, the stress concentration is caused by the difference in expansion. Therefore, the thermal shock stability of high alumina brick products is poor than that of clay brick products, and the general number of water cooling is only 3-5 times.
