Какие существуют классификации корундового кирпича?
В качестве высокоэффективного огнеупорного материала, корундовый кирпич широко используется в промышленных сферах.. В этой статье будут представлены две основные категории корундовых кирпичей.: fused corundum bricks и sintered corundum bricks, and discuss their application scope, characteristics, and production processes.
Introduction to fused corundum bricks

Fused corundum bricks are refractory products made from alumina powder through a high-temperature electric fusion process. In the preparation process, the alumina ore is first crushed and ground, then subjected to high-temperature electric fusion in an electric arc furnace, and finally solidified by cooling to form a hard corundum brick.

Due to their high density, высокая прочность на сжатие, стойкость к высоким температурам, устойчивость к коррозии, and other characteristics, fused corundum bricks are widely used in the lining and insulation layer of high-temperature industrial equipment such as electrolytic aluminum tanks and glass furnaces.
Introduction to sintered corundum bricks
Production process of sintered corundum bricks

Sintered corundum brick is a refractory product made of alumina powder sintered in a high-temperature environment. During the preparation process, the alumina powder is molded or extruded, and then placed in a high-temperature baking oven for sintering, so that the particles are combined to form a solid brick.
Characteristics of sintered corundum brick

Sintered corundum bricks are widely used in industrial fields such as high-temperature furnaces, steel smelting furnaces, and cement kilns due to their excellent thermal shock stability, износостойкость, и ударопрочность.

Corundum brick is widely used in many industrial fields due to its fire resistance, стойкость к высоким температурам, устойчивость к коррозии, и другие свойства:
- Металлургическая промышленность: used in the lining and heat insulation layer of blast furnaces, electric furnaces, converters, ковши, and other smelting equipment.
- Стекольная промышленность: As the lining of glass furnaces, its high-temperature resistance and corrosion resistance are fully utilized.
- Cement industry: In high-temperature areas such as cement kiln linings, it can effectively withstand high temperatures and chemical corrosion.
- Керамическая промышленность: It has good wear resistance on the inner wall, изоляционный слой, and other parts of ceramic kilns.
