ABSTRACT Company called: DAUSSAN ET COMPAGNIE "Process and plant for producing a lining on the inner walls of a metallurgical vessel" (Inventors: Jean-Charles DAUSSAN, Gérard DAUSSAN and André DAUSSAN) A metallurgical vessel (1) whose inner walls to be lined are relatively hot is placed on a suitable support; the support is tilted and the matallurgical vessel (1) is brought successively into a number of different positions, in each of which an inner wall or a part of wall of the vessel is substantially horizontal and turned upwards; in each of the above mentioned posi- tions at least one layer of a substantially dry material comprising a mixture of refractory particles and a binder of the thermosetting or equivalent type is spread on the said inner wall or part of wall, the composition and the particle size range of the mixture of refractory par- ticles being such that this mixture sinters in contact with the liquid metal, and this material is spread out so as to form a substantially uniform layer, the inner walls of the vessel being initially at a sufficient temperature to be able to heat the material deposited on them to a temperature permitting the softening and the setting of the binder of thermosetting or equivalent type and the formation of a monolithic lining (5) which adheres to the inner walls of the vessel. Use especially for producing a lining on the inner walls of a metallurgical vessel. (See Figure 1).
