Magnesia carbon brick

Introduction

Magnesia carbon brick main chemical composition is MgO and C, and no congruent phenomenon between MgO and C under high temperature. Magnesia Carbon brick is resin-bonded brick made from dead-burned or fused magnesia and graphite. Anti-oxidant is added if required. Magnesia Carbon brick has good performance in thermal resistance, corrosion resistance and spalling resistance.

Features

We produce a wide range of ladle MgO-C bricks. These bricks contain carbon (5%-20%) and fused, sintered, or large crystal magnesia. These products are resin-bonded and have powered metals added for oxidation resistance. These products are widely used in the ladle slag lines, transition zones, barrels, and bottoms.

1. High strength
       2. Excellent slag resistance
       3. High refractoriness
       4. Good thermal shock resistance
