ABSTRACT:
There is described a method for the hot repair of the protective layer provided on the permanent lining of a tundish of a continuous casting plant. The method can be carried out simply and quickly, with thermal losses of the tundish being largely prevented and heat influences on the personnel being eliminated, by retaining an amount of residual steel with a slag layer in the tundish. The residual-steel amount plus slag layer is cooled till solidification, is removed from the tundish in a still hot state, and a repair-mass constituting the protective layer is sprayed onto the permanent lining of the still hot tundish.
