Aluminum carbon bricks are mainly used as sliding nozzle slides, continuous casting tundish integral plugs and the like. Aluminum carbon bricks can also be used as a brick for pretreatment of molten iron and lining of steel drums.

Introduction
Aluminum carbon bricks are based on Al2O3 and C. Aluminium carbon brick is a kind of refractory material containing 35%~85% of Al2O3 and containing 7%~35% of C.

Aluminum carbon bricks have high refractoriness, good chemical stability and corrosion resistance. If ZrO2 is added to the ingredients, good thermal shock resistance can be obtained. The compressive strength of fired aluminum carbon bricks with Al2O3 content of 72%~85% and C7%~8% can reach 110~120MPa, the flexural strength at 1400°C is 25MPa, and the content of Al2O3 is 35%~46%, C+ The compressive strength of SiC 30%~37% fired aluminum carbon brick is 21~28MPa.

Use of aluminum carbon brick
Aluminum carbon bricks are mainly used as sliding nozzle slides, continuous casting tundish integral plugs, etc., and can also be used as lining for hot metal pretreatment and lining of steel drums.

This series of aluminum carbon brick products is made of bauxite clinker, corundum and graphite as main materials, and is incorporated into various differential additives. It has good microporous index, excellent alkali resistance and high thermal conductivity. Aluminum carbon brick is suitable for different furnaces and high aluminum furnace waist, belly, cooling wall aluminum brick and other parts

A carbon-containing refractory product made of corundum (or high alumina bauxite, mullite) and graphite. Aluminum carbon bricks can be divided into fired aluminum carbon bricks and non-fired aluminum carbon bricks according to different manufacturing processes.

Production Process
Process points for manufacturing fired aluminum carbon bricks: carbon raw materials are mixed into the main raw materials of alumina, and a small amount of other raw materials such as silicon powder, SiC powder, aluminum powder, etc. are added, and phenolic resin or asphalt is used as a binder, and is mixed and mixed. , isostatic pressing (or machine molding), firing in a reducing atmosphere.
