Ladle
First Claim
1. A liner for a ladle, the liner comprising a body of refractory material defining a hollow interior, the body having a continuous sidewall bounding said hollow interior, a lower closure floor and an open top, a barrier of refractory material facing an interior surface of part of the sidewall and being spaced inwardly therefrom in said hollow interior, the barrier extending from at or near the open top of the body towards said lower closure floor to define, with said facing part of said sidewall, a spout for discharging molten metal, in use, from said interior of the ladle, the barrier having two longitudinal edge surfaces, two facing inner portions of the sidewall being extended inwardly, said longitudinal edge surfaces of the barrier being received at said inwardly extended portions respectively, thereby positioning said barrier at said inward spacing from, and facing, said interior surface of part of the sidewall wherein said liner has a cylindrical or truncated cone shape outer surface and said spout does not extend outwardly of said outer surface.

Abstract
A liner for a ladle is formed of a body of refractory material defining a hollow interior which is bounded by a continuous sidewall. Within the interior is a barrier of refractory material which faces the interior surface of part of the sidewall and is spaced inwardly therefrom in the hollow interior of the body to define with said facing part of said sidewall a spout for discharging molten metal, in use, from the ladle. The barrier has two longitudinal edge surfaces received at two facing inner portions of the sidewall respectively which are extended inwardly. By providing these inward extensions the barrier can be positioned within the interior of the liner thereby obviating the need for an outward extension from the liner body to define a spout. This enables the liner to be used with ladle shells without the shell requiring modification to accommodate such an outward extension.

- 15. A ladle comprising an outer metal shell defining a hollow interior, the shell having a continuous inner sidewall, bounding said interior of the shell, a lower closure floor and an open top, and the ladle also comprising a liner, retained in said interior of the shell, in use, the liner comprising a body of refractory material defining a hollow interior, the body having a continuous sidewall bounding said hollow interior, a lower closure floor and an open top, a barrier of refractory material facing an interior surface of part of the sidewall of the body and being spaced inwardly therefrom in said hollow interior of the liner, the barrier extending from at or near the open top of the body towards said lower closure floor of the liner to define, with said facing part of said inner sidewall of the liner, a spout for discharging molten metal, in use, from said interior of the liner, the barrier having two longitudinal edge surfaces, two facing portions of the inner sidewall of the liner being extended inwardly, said longitudinal edge surfaces of the barrier being received at said inwardly extended portions respectively, thereby positioning said barrier at said inward spacing from and facing, said interior surface of part of the sidewall, wherein said liner has a cylindrical or truncated cone shape outer surface and said spout does not extend outwardly of said outer surface.
