A tundlish lid is described comprising a steel baseplate and refractory insulating layer. The refractory insulating layer has embedded in it a lattice, preferably of iron or steel, which is secured to retaining members themselves secured to one surface of the baseplate. By this means the refractory insulating layer adheres well to the baseplate. A method of making the tundlish lid is also described by positively securing the lattice in spaced relation from the surface of the baseplate by securing the lattice in slots in studs or retaining elements secured to the baseplate and then applying a layer of substantially uniform thickness of refractory insulating material over the lattice.
