  • Method for hot rolling Z-sections sheet piles
    Patent number: 9636724
    Abstract: A method for rolling a Z-section sheet pile comprises rolling a curved preform of a web (16) in successive roll gaps defined by at least one roll pair comprising a grooved upper roll (26) and a grooved lower roll (28), wherein: a first corner (18) and an adjoining first part of the curved preform of the web (16) are formed in a first groove (42) of an upper roll (26); and a second corner (20) and an adjoining second part of the curved preform of the web (16) are formed in a first groove (46) of a lower roll (28). In the last roll gaps forming the curved preform of the web (16), the diameter of the lower roll (28) decreases in a discontinuous manner in the interval between the first groove (42) in the upper roll (26) and the first groove (46) in the lower roll (26), and the diameter of the upper roll (26) increases in this interval in a complementary manner.
