An improved mould for the continuous casting of steel slabs having thickness in the range from 50-120 mm, particularly suitable to be rolled to thin strips, presents two large faces (F), each one having in horizontal cross section a concave or rectilinear central zone symmetrical with respect to each other, connected at both sides to the narrow faces (f) through concave-convex wide bends with respect to the internal part of the mould, without other lengths being parallel to opposite portions of the other face (F), besides to a possible central rectilinear length. the radiuses of the concave portion (r1) and of the convex portion (r2) are in a mutual ratio of a range from 0.6 to 1.4, these portions being preferably the same at each horizontal cross section of the mould and increasing downwards, while the depth (a) of the concavity decreases downwards, being possibly constant from a height (ybc) to the outlet section, but being preferably continuously decreasing along the whole length of the mould, with a residual depth &lE;5 mm at the outlet zone.
