The invention provides a tundish comprising a casing having a floor, including an impact area, and upstanding sidewalls, the casing having a permanent refractory lining, and at least one expendable beam of refractory heat insulating material extending between opposite sides of the casing adjacent the impact area. Generally the refractory heat insulating material is one comprising a major proportion of particulate refractory, a minor proportion of fibrous material and an organic binder. In the tundish there may be two pairs of said beams to bridge opposite sides of the casing, one pair being located at the sides of the impact area in or on the floor of the casing and the other vertically above the first, adjacent the top of each sidewall. |
