Abstract
Oscillating table for blooms or billets production plants, comprising pairs of bars, lying on at least one horizontal plane, which constitute the elastic support elements of the mold, thus permitting an optimal guidance of the oscillation thereof exclusively in the casting direction, said pairs of bars constituting a tie rod-strut system working in bending that confers to the table very high torsional and lateral stiffness. It allows a high precision in guiding mold thus consenting it wide oscillations in the axial casting direction only.
Claims12
Oscillating table comprising
- a mobile structure, inserted into a support structure fastened to the ground, the mobile structure comprising a continuous casting mold having a longitudinal axis X defining a casting direction and suited to being guided in an oscillation by first elastic means, arranged transverse to the longitudinal axis X,
- actuation means, suited to transmitting alternating impulses in a direction substantially vertical to the mold, in order to cause the oscillation motion thereof,
- characterised by the fact that said first elastic means comprise an even number of pairs of first elastic bars and an even number of pairs of second elastic bars, said pairs of first bars being arranged alternatively on two first planes parallel to one another and equidistant from said longitudinal axis X, and said pairs of second bars being arranged alternatively on two second planes parallel to one another and equidistant from the longitudinal axis X, said second planes being substantially perpendicular to said first planes in order to give the table a predetermined torsional and lateral stiffness around the longitudinal axis X and to allow the oscillation of the mold in the longitudinal axis X only.
Oscillating table according to 1 wherein said elastic bars have a round cross section.
