High alumina bricks

High alumina bricks of clinker with a certain amount of soil is a combination of vanadium clay made of AI2O3 content is more than 48% of the Al-Si refractory products. High alumina bricks production process and high quality clinker brick production process of multi-basically the same. The difference is that in the clinker crusher before grading selection process and screening process after the iron removal.

On the basis of the clay brick high alumina bricks, changing the AI2O3/SiO2 ratio increased AI2O3 content, and thus refractoriness and high temperature mechanical strength are superior to clay. Thus, a variety of thermal equipment, parts of the original with silica brick, or brick can be replaced with aluminum brick. With high alumina bricks to replace the brick and silica brick, can increase the service life of thermal equipment. Currently, it is mainly used for masonry furnace, stove, electric roof, ladle, cement kilns, glass kilns and chemical industry furnace, this is also used for open-hearth furnace regenerator lattice bricks, pouring system using plug head , outlet switch and so on.
