Abstract (en)
[origin: EP0547940A1] Coat lining of aluminous refractory concrete for container, e.g. pouring ladle containing a molten metal. According to the invention, this coat lining is characterised in that this container is incurvate and develops in the shape of a helix and is made either of a single moulded piece in the case of pouring ladles of small cross section, or in other cases, by assembling a plurality of independent pieces (2) also obtained by moulding which fit next to each other and which are locked in position by a polygonal contour piece (3) of trapezoidal cross section, forming a keystone; cavities (12, 13) are made in the bottom of the hollow part in order to receive seating bricks for the discharge aperture and/or the porous plug used for refining; the peripheral annular belt of the bottom of the ladle is made from pieces (2) which are similar to the preceding ones but which have an outer shoulder (4) defining a bearing surface with the vertical wall (15) of the pouring ladle, the said bearing surface forms a negative relief angle beta with respect to the bottom of the said ladle. <IMAGE>
