Method for forming a lining on a metallurgical vessel, a composition and a machine for the application of said method

A method for forming a protective lining on internal faces (2) of a metallurgical vessel (1) adapted to receive molten metal, which comprises the following steps:

• a) positioning at least one movable wall (3) extending substantially over the full height of said faces at a predetermined distance from an internal face (2) of said vessel,
• b) introducing a powdered composition (4) containing at least one powdered refractory material between the internal face (2) of the vessel ad the movable wall (3),
• c) heating said powdered composition so as to sinter said internal face adapted to receive said molten metal,
• d) transversely displacing said movable wall (3) along and with respect to said faces and to said composition already in place thereon, and repeating the above steps so as to obtain a continuous lining on said internal faces of the vessel.
