Abstract

It was difficult until now to carry out intermediate repairs of monolithic refractory lining walls of steel casting and handling ladles when the slag area of the lining was worn before other areas. According to this new process for reconstructing the refractory lining in the upper area of the wall, repairs may be economically carried out in that the gap between the lower end of the template and the lining that projects under the area to be reconstructed is sealed by inflating a hose-like sealing body and by deflating again the sealing body before removing the template. This process is useful for steel casting and handling ladles and for similar metallurgical vessels.
