  • Patent number: 6293133
    Abstract: A method of rolling finished sections from preliminary sections by means of roll stand arrangements which operate in reversing operation and include a compact rolling group composed of a first universal stand at the entry side and a second universal stand at the exit side and an intermediate edging stand arranged between the universal stands, and a roughing group arranged in front of the compact rolling group and composed of vertical roll stands and horizontal roll stands and/or universal stands. A rectangular preliminary section or a preliminary section having the approximate final dimensions is preshaped in the roll stands of the roughing rolling group in a number of shape changing passes and/or shape reduction passes, possibly reversing with or without the use of selectable grooves. Subsequently, the section is further shaped in the compact rolling group in several shape changing passes or shape reduction passes in the universal stand on the entry side.

  • Patent number: 6035683
    Abstract: A method of casting and rolling and a roll stand arrangement for rolling finished sections (sheet piling sections) from a preliminary section which arrives from a continuous casting machine and has approximate final dimensions. The method utilizes roll stand arrangements which operate in a rolling line in a reversing operation. A roughing rolling group has in a first rolling line a runout roller table and a transverse transport device following the runout roller table and in a second rolling line a parallel run-in roller table for a compact tandem stand group. A horizontal stand of the roughing rolling group and/or an intermediate edging stand of the compact tandem stand group each have two selectable grooves, wherein a universal stand on the exit side of the compact tandem group has one or more two-high horizontal stands with grooved rolls.
