description The invention discloses a method for detecting composition segregation on a steel billet corresponding to a steel rail, which comprises the following steps: when transverse composition segregation on the steel billet corresponding to the head of the steel rail is detected, taking a block at the position of the steel billet corresponding to the head of the steel rail, polishing the surface along the narrow surface direction from outside to inside, taking six points, and carrying out composition analysis by adopting a spectrum analyzer; then grinding off the surface by a certain thickness, continuously taking six points, carrying out component analysis by adopting a spectrum analyzer, and sequentially making a plurality of layers according to the method; and then component segregation analysis is carried out on each layer. After the method is implemented, a sample on a steel billet corresponding to the steel rail head is subjected to component analysis by a spectrum analyzer, and then each layer is subjected to
