Determining the resistance of refractories in a slag stream

Conclusions A method is proposed for testing refractories for slag resistance at 1500–1600°C. The results of investigation into high-grade refractories showed that their resistance is variable, and in the main is extremely low. Only silicon carbide, nitride-bonded silicon carbide, and carbon specimens will resist convective slag at 1500–1550°C. The other refractories were destroyed in varying degrees by the slag.Destruction of oxide refractories with an increase in the basicity of the slag is markedly increased, In these conditions nonoxide materials have about the same degree of destruction.Translated from Ogneupory, No. 8, pp. 53–58, August, 1967.
