Alumina-Magnesia Carbon Brick is a kind of refractory brick products which is mainly made of special-grade high-alumina bauxite or emery, magnesia and flaky graphite as the main material.
Composition of Alumina-Magnesia Carbon Brick
In order to improve the oxidization, can appropriately add some Si powder, Al powder, SiC powder or silica iron powder and other additives, with resin as the binding agent, high pressure forming, after treatment of 200～300℃, it can be used without calcination.
Property of Alumina-Magnesia Carbon Brick
Alumina-magnesia carbon brick has the advantages of anti-erosion resistance, anti-stripping, balanced erosion, safe using, easily package. It is widely used in rigorous molten steel ladle liner. This kind of refractory bricks are used in the molten bath and ladle bottom of continuous casting large tundish and external furnace refining package is increasing.
Advantages of Alumina-Magnesia-Carbon Bricks
- High corrosion resistance
- Anti-performance property
- Balanced erosion
- Safety in use
Manufacture Process of Alumina-Magnesia Carbon Bricks
With the special grade high alumina bauxite as raw material, owing to it has certain proportion SiO2 and other impurties, and the structure is not impact, the corrosion resistance of slag is poor. In order to improve the slag resistance, the fused or sintered corundum can replace part of special grade high alumina bauxite. In order to improve the resistance to oxidation and high temperature strength. So is the alimina-magnesia carbon bricks are produced.
Application of Alumina Magnesia Carbon bricks
For the use of the alumina-magnesia carbon bricks, they are mainly used in rigorous molten steel ladle. In Japan, the bricks used in the molten bath and ladle bottom of continuous casting large tundish and external furnace refining package is increasing.
