摘要

Method to obtain transverse vibrations in the walls (111) of the crystalliser (11) in an ingot mould (10), by means of a pulsation in the cooling liquid, the ingot mould (10) possibly having one or more peripheral areas (13a, 13b), disposed lengthwise, wherein the cooling liquid circulates around the sidewalls (111) of the crystalliser (11), the cooling circuit comprising a transit channel (16) directly in contact with one or more sidewalls (111) and at least feeding means consisting of a pump, a delivery pipe and a discharge pipe connected with a discharge side (21), the cooling fluid being made to circulate by means of the pump means around the sidewalls (111) of the crystalliser (11), in cooperation with at least one portion of the sidewall (111), the pressure of the cooling liquid in transit being of the pulsation type, the pulsation in the pressure being functional to the desired elastic transverse vibration induced on the portion of the sidewall (111).
