Abstract
Procedure for controlling the deformation of the walls of a crystalliser for continuous casting of billets or blooms 24, said crystalliser 11 co-operating internally with the skin of the billets 24 and externally with the cooling chamber 14 in which coolant fluid circulates and compromising an intermediate wall 20 defining a channel 21 circulating coolant fluid in counter-flow, there being at least one top zone co-operating with the part below the meniscus 27 of liquid metal and a bottom zone initiating around the zone of detachment of the skin from the outer face 12a of the wall of the crystalliser 11 and extending towards the exit of the crystalliser 11, each wall of the crystalliser 11 co-operating with its own circulating channel 21, the fluid pressure at the inlet of the circulation channel 21 being a function of the desired deformation of the wall in correspondence with the bottom zone of the crystalliser 11 and of the temperature of the crystalliser 11 and/or temperature of the wall and/or of the friction between the skin being extracted and the internal face 12a of the crystalliser 11, said pressure of the coolant fluid being regulated by means interlocked with a computer 18. Crystalliser for continuous casting of billets or blooms 24 co-operating internally with the skin of the billets/blooms 24 being formed and externally with a cooling chamber 14 in which a coolant circuit circulates and comprising an intermediate wall 20 creating, in co- operation with the external face 12b of the crystalliser 11, a circulating channel 21 with longitudinally differentiated transit aperture, there being at least one top zone co-operating at least with the part below the meniscus 27 and a bottom zone initiating around the skin detachment zone being formed from the internal face 12a, the crystalliser having walls with thickness comprised between 4 and 10 mm and, for each wall, individual channels 21 for circulating coolant fluid in counter- flow, the pressure of the coolant fluid at the inlet of the circulating channel 21 associated with the bottom zone being interlocked with a computer and being between 5 and 20 bar in the case of normal water. <IMAGE>
