Abstract
The invention relates to a method for manufacturing a metal ingot by continuous casting, comprising the following steps: S1: melting the metal, S2: transferring the liquid metal (2) by pouring it into a crucible (12), S3: moving the base plate (14) of the crucible (12), S4: progressive solidification of the liquid metal (2) from the base plate (14) of the crucible (12), and S5: during the step S3 of moving the base plate (14), applying a compression force to the metal (3) which is present between the base plate (14) and the side wall (13), the compression force being applied along a second axis (X2) parallel to the first axis (X1) so as to deform the metal and to obtain an ingot (3) which has a smaller width (L2).
