The invention relates to a refractory ceramic brick assembly. In other words: The subject of the invention relates to a multiplicity of refractory ceramic bricks which are arranged to one unit in a specific way, i. e. combined with each other.

A ramming mass for the block lining of at least some of the refractory elements of a refractory lining of a metallurgical vessel such as a blast furnace, said ramming mass being composed of a mixture of a granular phase and a binder phase, wherein the granular phase and/or binder comprises at least one component having a microporous structure or capable of forming a microporous structure by firing during the blast furnace campaign. The ramming mass is in particular intended for forming the joint between two concentric annular assemblies forming a side wall of the vessel or between a lower part of an inner annular assembly and the periphery of one or more refractory layers forming the floor of the vessel.

An installation for applying a lining composition in the form of dry particulate material (2p) is provided to form a working lining (2s) onto a surface of a cavity in a tundish (1). A space reference system (X, Y, Z), where X is a longitudinal axis, Y is a transverse axis, and Z is a vertical axis is used. The installation includes a support frame defining a passage, a tank for storing an amount of the dry particulate material, dispensing units, a plunger configured for fitting in the cavity, a longitudinal translation mechanism is configured for holding and translating the dispensing along the longitudinal axis, a transverse translation mechanism is configured for receiving the tundish and translating the tundish along the transverse axis of the passage, and an elevation translation mechanism is configured for holding the plunger and translating the plunger along the vertical axis of the cavity when the tundish is located in the passage.
