Magnesia Carbon Brick

Magnesia Carbon Brick Introduction

Magnesia carbon refractory brick is a high melting point basic oxide magnesium oxide (melting point 2800 degreeC) a high melting point carbon material, magnesia carbon brick is difficult to be infiltrated by slag as a raw material, various non-oxide additives are added. A non-burning carbon composite refractory material combined with a carbonaceous binder. Magnesia carbon brick is mainly used for the lining of converter, AC arc furnace, DC arc furnace, slag line of ladle.

Magnesia Carbon Brick Features

1. Magnesia carbon bricks have strong slag resistance

2 .Magnesia carbon bricks have low temperature creep low

3 .Magnesia carbon bricks have good thermal shock resistance

4..Magnesia carbon bricks have good high temperature resistance

Magneisa Carbon Brick Application

1. Magnesia carbon fire brick is mainly used for the furnace lining and tapping of steelmaking oxidation converter.

2. Magnesia carbon firebrick is mainly used for hot spot of high-power electric furnace wall, lining of refining furnace outside furnace, slag line of steel drum.

How to Improve Magnesia Cardon Brick Using life

The excellent performance of reractory magnesia carbon brick depends on the presence of carbon in the brick. The oxidation of carbon during its use tends to cause deterioration of the structure of the product, causing the slag to invade the brick along the gap, eroding the magnesium oxide particles and reducing the service life of the magnesia carbon brick. At present, the antioxidant resistance of magnesia carbon bricks is improved by adding antioxidants, and the using life of magnesia carbon bricks is improved.

Magnesia Cardon Brick Manufacturing Process

Magnesia Cardon Bricks Select Raw Material

The main raw materials for magnesia carbon bricks include fused magnesia or sintered magnesia, flake graphite, organic binders and antioxidants.

Magnesia sand is the main raw material for the production of magnesia carbon bricks, magnesia refractory bricks are divided into fused magnesia and sintered magnesia. Compared with sintered magnesia, fused magnesia has the advantages of coarse magnesia crystal grains and large bulk density, which is the main raw material for the production of magnesia carbon bricks.

Magnesia Cardon Bricks Using Flaky Graphite as Carbon Source

Graphite as the main raw material for the production of magnesia carbon bricks, which is mainly benefits from its excellent physical properties:

1 non-wetting property to slag

2 high thermal conductivity

3 low thermal expansion

Magnesia Cardon Bricks Binding Agent

Common binders for the production of magbesia carbon fire bricks include coal tar, coal tar and petroleum asphalt, as well as special carbonaceous resins, polyols, asphalt modified phenolic resins, synthetic resins.
