<p>The invention relates to a method of locating a slab of refractory heat-insulating and/or exothermic material on the surface of a molten metal in an ingot mould or other vessel. The slab has at least one prongreceiving socket, accessible from an edge or the top of the slab, the socket or sockets having an upper bearing surface in the plane of the slab. The locating method involves advancing a pronged tool having an elongate handle to the slab, engaging the prong or prongs of the tool in a respective socket of the slab, and moving the slab by means Or the tool to overlie the molten metal. The slab is then released from the tool to fall on to the molten metal and there to assume a generally horizontal position.</p> |
