The use of high alumina refractory bricks

High alumina refractory bricks have a good heat insulation effect and can be applied to the thermal insulation layer of thermal contact furnaces and hot blast furnaces. High alumina poly-light bricks are also widely used in coking furnaces and heating furnace thermal equipment in the metallurgical industry.

Precautions for the use of high alumina bricks

Storage: High alumina bricks should be stored in a dry and ventilated place, avoiding contact with water or moisture, so as not to affect its performance. Avoid contact with acidic and alkaline substances to prevent chemical reactions.

Cutting: High alumina bricks can be cut by mechanical equipment or by hand, but care should be taken not to break or crack when cutting, otherwise it will affect its use effect.

Installation: High-alumina bricks need to be fixed with high-temperature refractory glue or refractory mortar. The dust and impurities on the installation surface should be cleaned before installation to ensure that the glue or mortar can be firmly bonded.

Maintenance: High alumina bricks may be subjected to mechanical shock or chemical attack during use, and regular maintenance is required. If it is cracked or damaged, it should be replaced in time.

High alumina insulation brick delivery

After receiving the order, the factory will produce it immediately and generally ship it within 7-12 دن. It will take longer to customize the size of high-alumina insulation bricks.
