Abstract:
1. A casting apparatus for the continuous casting of a thick slab with a quadrangular section having a longitudinal side of a length far greater with respect to a transverse side, comprising an ingot mold comprising a quadrangular mold cavity having a longitudinal axis X defining a casting direction, and an oscillating table comprising said elastic bars comprising the plurality of first pairs of elastic bars arranged alternately substantially on two first planes parallel to one another and to the longitudinal axis X, equidistant from said longitudinal axis X, and on opposite sides of the longitudinal axis X, wherein the plurality of second pairs of elastic bars is arranged alternatively on two second planes parallel to one another and to the longitudinal axis X, equidistant from said longitudinal axis X, and on opposite sides of the longitudinal axis X, wherein, on each of said first and second planes, each elastic bar of each first and second pairs of elastic bars has a first end fixed to the ingot mold and a second end fixed to the load bearing structure, and wherein said second planes are substantially perpendicular to said first planes in order to give the table a predetermined torsional stiffness around the longitudinal axis and a predetermined lateral stiffness in directions orthogonal to the longitudinal axis and to allow the oscillation of the ingot mold in the casting direction only wherein inner ends of the first elastic bars of each pair are spaced by a distance equal to approximately the length of the longitudinal sides of the mold cavity section.
