Abstract (en)

[origin: DE4403270C1] 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.
