Abstract
A refractory pouring-assembly component for use with a tube changer mechanism, the component having a throughbore for pouring of molten metal during continuous casting from a tundish into a mould and being isostatically pressed from different heat- and wear-resisting reffactories to form a one-piece composite body having at one end a smooth, flat plate surface in which there is defined an aperture, at least the peripheral edge around said aperture being formed of a hard refractory material to provide a cutting edge around the through-bore, whilst the remainder of said body is formed from a thermal shock-resistant material to provide for pouring of melt.
