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.

Abstract: The present invention relates to a cover for a tiltable ladle said cover having a pouring basin with at least one opening in its bottom communicating with the ladle. The cover is suspended in the horizontal beam of a ladle support frame by springs, said springs being intended to lift the cover away from the top of the ladle when the pouring basin is empty.

Abstract: Slag-free discharge of molten metal from a smelting furnace is assured either through slow tilting through a small angular range in case the outlet is located in a lateral bay extension of the furnace such that maximum depth level is retained above the outlet and the furnace is tilted back to a slight negative angle once the formation of eddys that could suck slag into the outlet becomes likely. In the case of a central discharge outlet, maximum depth level is still maintained above the outlet but the slag is stiffened, i.e. rendered highly viscous, so that any eddy will not tear slag particles off and suck it into the outlet. Certain ratios of water cooled surfaces to fire proof surfaces are to be observed.

Abstract: The improved crucible of the present invention both filters molten metal during the transfer of the molten metal from a supply receptacle such as a melting furnace to a receiving receptacle such as a mold. The transfer crucible of the present invention may be either portable or permanently mounted. The present invention relates to both the design of the improved transfer crucible and to the method for using the improved transfer crucible. The transfer crucible of the present invention is fitted with one or more removable blades, each of which contains a filter element. Molten metal can be filtered while the crucible is being filled with molten metal, during transfer of molten metal, or if desired molten metal can be filtered both on entry into and on exit from the transfer crucible.

Abstract: A teapot ladle has an interior lining of low thermal capacity, low thermal conductivity refractory material which in contact with molten metal poured into the ladle forms an erosion resistant surface, and means for retaining the lining in place when the ladle is tilted.The lining material comprises inorganic fibrous material, particulate refractory material and an organic binder and the retaining means may be a refractory or metal ring which clips over the outer wall of the ladle and the inner wall of the lining, a series of clips or a rod shaped to fit over the top of the ladle and hold the lining in one place at one point on its perimeter.
