When antioxidants are used to protect the carbon in carbon-bonded refractories against steel melts, excellent results are afforded by boron compounds. In addition, they also enhance the mechanical properties of the carbon-bonded refractory materials.
Increasing requirements in steel production processes are imposing greater demands on steel furnace refractories. Most of these demands are met by carbon-bonded brick and compounds. As a thermally stable material, carbon increases the thermal shock resistance of refractory compositions and prevents wetting by metal and slag, but it is highly susceptible to oxidation.
In steel production, refractories of higher ...
