Abstract

PURPOSE:The highly durable spray material for use of hot repairing work, suitable for contriving the effective reutilization of the converter slag, prepared by coating the converter slag with the pitch, synthetic resin, etc. CONSTITUTION:The converter slag, under the circumstances, is mixed with the basic refractory like as the magnesia clinker, etc,; this coarse or fine particle is coated with the pitch or synthetic resin, or is mixed with the powdery pitch or synthetic resin; hereby, the basic spray material for hot repairing work is prepared. As for the pitch, the tar pitch, petroleum pitch, asphalt pitch, etc., are available; and as for synthetic resin, phenol resin, furan resin, etc., are available. These pitch or synthetic resins are specified to detain the residual carbon content 30-70%.
