Abstract: When the wall and bottom of a steel casting and handling ladle are provided at the same time with a refractory monolithic lining, the lining in the lower area of the wall is often damaged during intermediate repairs of the bottom. According to a new process, wall and bottom are lined one after the other. A hose-like inflatable sealing body is secured to the bottom part of the template 4 when beginning to introduce the casting mass in the wall area and is inflated so that it seals the template 4 up to the height that corresponds to the desired thickness of the bottom. As soon as the casting mass in the lower wall area is sufficiently set, the sealing body 2 is deflated and removed, then the refractory casting mass is introduced into the bottom area up to the desired height. This process is suitable for steel casting and handling ladles and for similar metallurgical vessels.

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.
