Abrégé

The invention concerns a mould for continuous casting of long or flat products, said mould extending along an axis (z) and comprising an internal and an external surface delimiting a mould thicknesses (e, e', e3, e4), the internal surface defining a mould cavity, characterized in that a thickness (e3, e4) of at least a longitudinal element (16A, 16C) of the mould contained in a longitudinal cross-section of the mould (10) increases, at least on a portion of the mould (10), from a point P of minimum thickness in both directions defined by the longitudinal axis (z), the increase depending on a measured or simulated temperature gradients of a test mould in use. The invention also concerns a method of making such a mould, a cooling jacket design to cooperate with such a mould and an assembly comprising such a mould and such a cooling jacket.
