Abstract: A die (for a continuous casting installation) that includes a movably mounted frame having a first subframe and a second subframe; a first broad-side insert which is positioned on the first subframe; and a second broad-side insert which is positioned on the second subframe. Narrow sides each having a narrow-side copper plate and abuting the two broad-side inserts are positioned between the two broad-side inserts. The die also has: a clamping device which is designed to exert, on the subframes, a clamping force that acts between the subframes; and an oscillation drive which is designed to make the frame oscillate in and counter to a horizontal width direction (H) relative to the narrow sides. A spring band assembly which guides the subframes is positioned on each subframe on sides which are opposite one another in the width direction (H).

Abstract: First, an auxiliary cut-out (11, 16) is formed in a side wall (1) of a continuous casting mold. That cut-out extends, in the longitudinal direction, at least over the cut-out length (L) of the useful cut-out (10) and has an auxiliary cross-section orthogonal to the longitudinal direction. Then, an additional element (13, 14, 17) is inserted into the auxiliary cut-out (11, 16), and extends, in the longitudinal direction, at least over a cut-out length (L) of a later useful cut-out (10) and bounds the useful cut-out (10) orthogonally to the longitudinal direction at least over part of the periphery of the useful cut-out. The useful cut-out (10) is formed by inserting the additional element (13, 14, 17) into the auxiliary cut-out (11, 16). The useful cut-out (10) is closed all around orthogonally to the longitudinal direction. Orthogonally to the longitudinal direction, the useful cut-out has a (correspondingly small) useful cross-section and a maximum useful extent (d3).
