Abstract: Segregation of carbon or alloying elements in a solidifying liquid core during casting of a continuous metal strand of high carbon steel or alloy steel, are disbursed by vibrating hammers engaged with a solidified shell enclosing a liquid steel core. The hammers are located before the end of the liquid core. A vibrator operating at a frequency of between 1000 and 5000 cycles per minute is coupled to the hammers by a support structure forming a dead weight mass for maintaining a metal-to-metal contact with the solidified shell while vibrated by the vibrator. The support structure is guided for stabilizing the hammers and for displacement of the hammers between an operative position and inoperative position.

Abstract: An apparatus for the continuous casting of slabs has a mold and a slab support zone immediately following the mold. The mold is made up of four separate plates which are held together to define a mold cavity. A dividing wall can be removably mounted in the mold cavity in order to divide the same into a pair of parallel casting passages. Insertion of the dividing wall in the mold cavity makes it possible to simultaneously cast two relatively narrow slabs rather than a single wide slab. A partition designed to constitute an extension of the dividing wall is provided for the support zone and can be removably mounted in the same. Both the dividing wall and the partition are carried by a clamping mechanism which serves to clamp the dividing wall in the mold cavity.

Abstract: A vertical slab mold has a pair of spaced wide walls, and a pair of spaced narrow walls which are located between the wide walls. The narrow walls are movable towards and away from one another for the purpose of performing width changes during casting. Drives for remote adjustment of the narrow walls during casting are connected with the narrow walls. A support for the narrow face of a slab is mounted immediately below each of the narrow walls and constitutes a downward extension of the respective narrow wall. The upper end of each support is articulated to the bottom of the associated narrow wall so that the support pivots relative to the narrow wall towards and away from the other support. A biasing element acts on the lower end of each support to urge the latter towards the other support and, hence against an adjacent narrow face of a slab. The biasing elements are designed to permit the supports to follow changes in the contours and/or positions of the narrow faces of the slab.
