Product Description

Product Description

Description of Alumina carbon brick

Aluminum carbon brick is a kind of brick mainly used as sliding nozzle slide plate, integral stopper rod of continuous casting tundish, etc.

Aluminum carbon bricks are refractory materials containing Al2O3 35%~85% and C7%~35% with Al2O3 and C as the main components. It can be divided into two categories: fired bricks and non-fired bricks.

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 containing Al2O372%~85% and C7%~8% can reach 110~120MPa, and the flexural strength at 1400 °C can reach 25MPa; containing Al2O335%~46%, C+SiC30%~37% The compressive strength of the fired aluminum carbon brick is 21~28MPa.

Advantage of Alumina carbon brick

 

(1) Low porosity & low air permeability.
(2) high crushing strength & high thermal conductivity.
(3) Anti-slag, anti-alkali, anti-erosion ability.
(4) Good thermal shock stability.

Production Process

Product Application

Fired aluminum-carbon bricks belong to ceramic bonding or ceramic-carbon composite bonding materials. Non-burning aluminum carbon bricks are carbon-bonded materials. Because the oxidation resistance is obviously better than that of magnesia carbon bricks, and the corrosion resistance of Na2O series slag is excellent, it has been widely used in molten iron pretreatment equipment.

Packaging & Shipping
