Abstract
An improved continuous caster mold having adjustable end walls employs heating mechanisms in the portion of each of the narrow end walls above the level of molten metal contained in the mold to heat that portion of each of the end walls to a temperature more closely approximating the temperature of the end walls below the level of molten metal in the mold. The heating mechanisms tend to lower the temperature differential between the portion of the end wall below the level of molten metal and the portion of the end wall above the level of molten metal. By equalizing the temperature differential in the end wall, the thermal expansion of the end wall is made more uniform to prevent the formation of a gap between the end walls and either of the broad side walls. The improvement is also useful for reducing thermal stresses in molds having fixed, stationary end walls.
