Exceptional Ladle Magnesia Carbon Brick

Product Introduction

Magnesia Carbon Brick is a non-burning carbon composite refractory material made from high-melting point alkaline oxide magnesia and high-melting point carbon materials that are resistant to slag erosion, with various non-oxide additives added, and bound together with a carbonaceous binder.

Magnesia Carbon Brick is mainly used for lining in converters, AC electric arc furnaces, DC electric arc furnaces, and the slag line of ladles.

Product Use

Magnesia Carbon Brick, as a composite refractory material, combines the anti-slag erosion properties of magnesia and the high thermal conductivity and low expansion properties of carbon, compensating for the poor spalling resistance of magnesia.

1. High-Temperature Resistance: Magnesia and carbon do not form eutectics at high temperatures, exhibiting excellent high-temperature performance.

2. Strong Resistance to Slag Erosion: Magnesia has strong resistance to alkaline and high-iron slags, while graphite has a high contact angle with slags and poor wettability.

3. Good Thermal Shock Resistance: Graphite has a high thermal conductivity, low linear expansion, and a small elastic modulus. Its strength increases with temperature, providing excellent resistance to thermal shock or rapid temperature changes.

4. Low High-Temperature Creep: Magnesia Carbon Brick's matrix consists of high-melting-point graphite and finely powdered magnesia, forming a robust carbon bond network between particles, preventing slip. There is little coalescence between graphite and magnesia, resulting in minimal liquid phase.
