Abstract: A device for use in relining a refractory-lined cover of a large vessel, particularly a tundish used in continuous casting of metals. The device comprises a stationary table and a rectangular frame hingedly supported at one edge of the table to be turned between a first position alongside the table and a second position overlying the table. An upright cover is fixed temporarily to the frame in the first position. The frame and cover are turned to the second position and the old refractory chipped out. Next they are returned to the first position to dump the old refractory. They are turned back to the second position to install new refractory.
