Abstract

A refractory pouring-assembly component (1; 21; 31; 41) for use with a tube changer mechanism comprises an elongate tubular body having a throughbore (2; 22; 32; 42) for use with a tube changing mechanism to provide a replaceable means for pouring of molten metal during continuous casting from a tundish (19) into a mould wherein the refractory pouring component is an isostatically pressed, heat- and wear-resisting refractory one-piece composite body (1; 21; 31; 41) which is shaped to provide at one end a smooth, flat plate surface (3; 23; 33; 43) in which there is defined an aperture (4; 24; 34; 44), the peripheral edge (3'; 23'; 33'; 43') around said aperture being formed of a hard refractory material to provide an edge which during a tube changing operation is capable of cutting a skin or shell of solidified melt formed within the throughbore (2; 22; 32; 42) of the pouring assembly during pouring of molten metal therethrough, whilst the remainder of said body is formed to a tubular shape from a thermal shock-resistant material to provide for pouring of melt. The compositions of said component may be uniform blends of refractory material bonded by silicon nitride or silicon oxy-nitride or an annulus of selected hard materials within a graphite/alumina host body.
