Abstract
The invention relates to a metallurgical vessel, in particular a transport ladle or a treating ladle, for the production of steel with a bottom (2b) having a refractory lining (3) with a basic working layer (5). In order to create a durable lining it is provided that the working layer (5) consists at least in part of dry basic bulk material, the upper side of which is covered, before the vessel (1) is heated for the first time, by a chemically hardened protective layer (6) and which, after the vessel (1) has been filled, is partly present as a monolithic layer or the upper side of the working layer (5) is covered, before the vessel (1) is charged for the first time, by a monolithically fritted basic layer formed by heating the bulk material. The invention furthermore relates to a method of making the refractory linings of such vessels.
