Oscillating Table

Oscillating table for plants 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

• a support structure, solidarity fixed to the ground, supporting an ingot mould comprising a crystalliser having a quadrangular section defining a casting direction X of said thick slab, wherein said ingot mould can be guided in an oscillation by first and second pairs of elastic bars arranged transverse to the casting direction,
• actuation means suited to transmit alternating impulses, in a substantially vertical direction, to the ingot mould, in order to cause the oscillation motion thereof,
• said elastic bars comprising a plurality of first pairs of elastic bars arranged alternately substantially on two first planes parallel to one another and to the casting direction X and equidistant from said casting direction X characterised by the fact that
• the plurality of second pairs of elastic bars is arranged alternatively on two second planes parallel to one another and to the casting direction X, and equidistant from said casting direction X, each elastic bar of each first and second pairs of elastic bars has a first end fixed to the ingot mould and a second end fixed to the support structure, in the opposite way to the corresponding ends of the immediately adjacent other bar of the same pair,
• said second planes being substantially perpendicular to said first planes in order to give the table a predetermined torsional stiffness around the casting direction and a predetermined lateral stiffness in directions orthogonal to the casting axis and to allow the oscillation of the ingot mould in the casting direction X only.
