Zusammenfassung:PURPOSE:To improve corrosion resistance against low basicity slag by incorporating magnesia-base refractory material, carbon-base refractory material, CaCO3 and/or MgCO3, and a specified metal powder. CONSTITUTION:A mixture of 55-97wt.% magnesia-base refractory material (e.g. electrofused magnesia clinker) containing MgO by 99wt.% and 45-3wt.% carbon-base refractory material (e.g. flake graphite) containing immobilized carbon by >85wt.% is prepared. This mixture by 70-99wt.% and CaCO3 and/or MgCO3 of
