METHOD TO CONTROL THE AXIAL POSITION OF SLABS EMERGING FROM CONTINUOUS CASTING AND RELATIVE DEVICE

摘要

Method to control the axial position of slabs emerging from the continuous casting machine, the method providing to control the axial position of the slab (24) in correspondence with the inlet to the first rolling stand and to act in feedback on means to modify the correct position of the axis (32) of the slab (24) in a position located between the first rolling stand and the foot rolls (26) of the ingot mold (13) from which the slab (24) emerges and wherein, in order to intervene upstream of the furnace (15) cooling systems (28) are employed which act on the sides of the slab (24), the method also using alignment means operating inside the furnace (15) and inducing a controlled lateral displacement governed by the control of the axial position of the slab (24). Device to control the axial position of slabs emerging from the continuous casting machine comprising cooling means cooperating with the sides of the slab (24) extracted from the ingot mold (13) and alignment means operating inside the heating and temperature maintenance furnace (15) and inducing a lateral displacement of the slab (24), the means (28) and the alignment means being governed by means (31, 36) to control the position of the axis (32) of the slab (24).
