Abstract

A method of changing the cross-sectional format of a strand when continuously casting strands by using a mould, involves at least one mould side wall which is displaced relative to an opposite mould side wall and has its inclination changed. According to the method the displacement of the mould side wall during casting is effected by step-wise changing of the inclination in a manner that, in a first step, the upper or lower rim region of the mould side wall is displaced in one direction, and, in a second step, the opposite rim region of this mould side wall is displaced in the same direction.
