Abstract
A wall structure for a metallurgical vessel at the location where the vessel wall, on the hot side, is in contact with liquid metal and/or liquid slag, in particular for the hearth of a shaft furnace, comprising a steel plate lining (2), inside which lining at least one layer of refractory brickwork (15, 16, 17) is arranged, the steel plate lining (2) being joined to the layer (layers) of brickwork by means of mortar joints (5) and/or ramming compound joints (5) to form a cohesive structure, wherein metal bars (11) which run in the circumferential direction inside the steel plate lining (2) and project into the wall are present, which bars are connected to the outer side of the steel plate lining by means of attachment means (20) running through the steel plate lining, each assembly comprising a metal bar (11) and its attachment means (20) and the steel plate lining (2) forming, in the vertical direction, a unit which is sufficiently elastic to maintain a surface-to-surface contact along horizontal surfaces between the metal bars (11) and bricks (15, 16, 17) during operation.
