ABSTRACT:
A method for adjusting the casting width of a continuous metal, in particular steel, casting mold in which two displaceable end walls are clamped between two large side walls with a predetermined clamping force. Prior to making the adjustment the clamping force acting on the end walls is released and one large side wall is displaced away from the abutting end walls to form a gap between them so that the end walls can be moved to the desired position. They are then clamped again between the two side walls. To attain an optimum gap width between the end and side walls by taking the actual mold dimensions at the time of adjustment into consideration, the thermal expansion of the end walls in a direction parallel to the axis of the tie rods is measured during casting, or at least during the start-up period of the continuous casting process until it has reached its equilibrium state. The adjustment is the made by adding the desired, optimum gap width to the actual, measured expansion of the end walls.
