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.

Claim 1
Independent Claim
149 words
A method of casting a metal slab from a continuous casting mold having a pair of fixed and opposed broad walls and a pair of opposed narrow walls, said broad and narrow walls cooperating to form a molten metal reception cavity adapted to receive molten metal to a predetermined level, said predetermined level being below a certain portion of each of said pair of opposed narrow walls, said method cooling said received molten metal effective to form a continuous slab; and locally and continuously applying heat to said certain portion of each of said pair of opposed narrow walls only above said predetermined level, effective to create thermal expansion of said certain portion and thereby prevent the formation of a gap between one of said pair of narrow walls and one of said pair of broad walls as said received molten metal is cooled and formed into said slab.
