Abstract
In a method for manufacturing a sidewall member of a continuous casting mold from a copper blank, wherein the sidewall member has an upper and a lower edge and a curved widened area beginning at the upper edge and tapering in a direction to the lower edge and to the sides of the sidewall member, the copper blank is hot-forged via several intermediate shapes to a rectangular plate with an initial wedge shape. The rectangular plate is then further formed by final hot-forging in a longitudinal direction of the rectangular plate with a straight saddle, having a width that is only a portion of a width of the rectangular plate measured relative to the longitudinal direction of the rectangular plate, and the curved widened area is pre-forged. Subsequently, the rectangular plate is quenched and work-hardened. The rectangular plate is then cold-hammered via a wedge-shaped bottom saddle for work-hardening a middle portion of the rectangular plate and for producing a final wedge shape of the rectangular plate. Finally, the entire curved widened area is work-hardened with a narrow saddle.
