ROLLING STAND FOR TUBES OR ROUNDS

摘要

A rolling stand for tubes or rounds comprising two or more rolls (10 20 30) defining a rolling section of the rolling stand that is coaxial to a rolling axis Y of the same stand each roll having a respective rolling surface (S1 ) defining a respective straight line of symmetry (B) passing through the rolling axis and through the center of symmetry of the respective surface thus determining a first half and a second half of the respective surface two gap zones having a radial distance of value H2 from the rolling axis and a groove bottom zone (1 ) having a radial distance of value H1 from the rolling axis at the intersecting point of the respective surface with the respective straight line of symmetry characterized in that it provides for each roll on said respective rolling surface at least one first pushing zone (2) and at least one second pushing zone (3).
