摘要:
A side guide for a rolling train has a band element and a transverse force device attached to the band element. The band element is designed for the at least partial lateral delimitation of a transporting path of the rolling train along a longitudinal axis of the band element. The transverse force device has a force generating unit for generating a transverse force orthogonal to the longitudinal axis of the band element and a force transmitting unit, coupled to the force generating unit, for transmitting the transverse force to a rolled product led through the rolling train.

A Steckel mill has a reversing unit for rolling a rolled product and winding furnaces arranged on the entrance side and exit side of the reversing unit. When rolling the rolled product in a region of a head of the rolled product, a target thickness of the rolled product is ignored, while measuring a current thickness and/or a hardness of the rolled product and comparing this with a setpoint value. One the measured variable reaches or is below the setpoint value, the reversing unit is operated with a view to achieving the target thickness of the rolled product. The Steckel mill is operated to allow for rolling of a cold, non-rollable piece of the rolled product, so that malfunctions are avoided and the usable part of the rolled product is as large as possible.
摘要:
In a rolling process for reverse thermomechanically rolling an aluminum plate involving a plurality of rolling passes, identifying data are determined for thermally guiding the rolling process. Then a value of a state variable, from which a temperature of the aluminum plate can be deduced, is continuously measured and a pass schedule is determined for the rolling process on the basis of the value of the measured state variable and of the identifying data. The pass schedule provides for a rolling pause between at least two successive rolling passes, during which rolling of the aluminum plate is interrupted for cooling purposes.
摘要:
A method influences the geometry of a rolled item in a controlled manner. In the method, the rolled item is transformed from an initial condition into an intermediate or final condition by rolling with the aid of a rolling stand having at least one processing assembly. An improvement in the geometry of the rolled item, particularly during processing of asymmetric rolled items, is achieved in that the at least one processing assembly is operated in a force-controlled manner on the basis of a desired force.
