A continuous casting mold for casting a strand has side walls defining an open-ended mold cavity. In order to increase the casting speed while maintaining a simple mode of construction of the continuous casting mold, the latter has the following characteristic features: at least two oppositely arranged side walls are rigidly fixed relative to each other about a pour-in section of the mold cavity and have a conicity decreasing in the running direction of the strand and, in a run-out section of the mold cavity arranged to follow the pour-in section in the running direction of the strand, include side wall sections movable relative to the strand and pressable at the strand by pressing devices, which side wall sections are arranged at a slighter conicity than the slightest conicity of the side walls of the pour-in section of the mold cavity.

Continuous casting mold

A continuous casting mold includes an oscillation mechanism and a guiding mechanism supporting the continuous casting mold relative to a stationary supporting structure, the guiding mechanism being formed as a disc-shaped spring. In order to ensure perfect guidance by employing a simply structured oscillation mechanism and to markedly reduce the masses to be moved, at least one disc-shaped spring formed as an annular disc peripherally surrounds the continuous casting mold, which annular disc by the inner edge region is connected with the continuous casting mold and by the outer edge region is connected with the stationary supporting structure.

A continuous casting mold having side walls through which a coolant flows includes a hydraulically operated oscillation device and a guiding device supporting the continuous casting mold relative to a stationary supporting structure. In order to do with a structurally very simple oscillation device having slight masses to be moved and to markedly reduce the space required by the oscillation device in the vicinity of the continuous casting mold, the oscillation device includes a pulsator setting the coolant into a pulsating pressure course and a supporting device is provided between the continuous casting mold and the stationary supporting structure, resiliently acting in accordance with the pulsating pressure course of the coolant and absorbing oscillation forces.
