Definitions
- the invention relates to a method and a plant for producing metallic hot strip from cast thin strip, which is rolled in its heat in its cast width, in particular to a thickness of 1-10 mm.
- Such hot strip is cast in continuous casting plants or in two-roll casting machines and then rolled to a winding thickness in individual roll stands or in roll stand groups or in rolling trains.
- JP8224639 A After casting strip material in a two-roll casting machine, to roll the cast strip and, after rolling, to cut it to its predetermined width and then to wind it up.
- this method has the disadvantage that the metal strip, in particular the steel strip, which is trimmed after rolling, determines the structural width of the first roll stand and all subsequent roll stands. This procedure leads to extra wide cast and rolled strips, which inappropriately increase the required rolling work and the size of each stand.
- the object of the invention is to achieve savings in the width of the installation and thus also savings in the design of roll stands and subsequent parts of the installation, as well as energy savings in the rolling process.
- the object is achieved according to the invention in that the hot strip is trimmed before entering one or more roll stands. This reduces the strip width in advance, which is then fed to the rolling process. With a reduced bandwidth, less deformation work is also required and the energy to be supplied to the drive organs NEN is decreasing. Furthermore, the construction of the roll stand is reduced in advance to a smaller width and load, so that the costs for the manufacture of the roll stand or a plurality of roll stands can be reduced.
- the hot strip is trimmed symmetrically to the longitudinal axis of the strip on both long sides.
- the hot strip is trimmed immediately before the first roll stand.
- the cast width of the strip is approximated to the width of the strip which will subsequently result from roll spreading.
- the plant for the production of hot strip which can be produced in a casting plant and can be rolled out of the casting heat in one or more roll stands to a thickness that can be wound in a reel, achieves the object according to the invention in that one before the entry into a first roll stand Trimming line aligned trimming device is arranged for double-sided trimming of the hot strip. As a result, the aforementioned energy savings and a saving in the width of the roll stand or stands are achieved.
- the edging device is arranged between driver devices.
- the driver devices in front of and behind the trimming device stretch the tape for cutting the edges and exert a necessary tensile force in addition to the transport force.
- the trimming device is equipped with rotating knives. As a result, longitudinal cuts are carried out continuously at the speed of the belt transport.
- the trimming width can be adjusted in the trimming device. This makes it possible to readjust the trimming width depending on the cast tape or in the event of format changes.
- a profile measuring device is arranged in front of the first roll stand. Depending on the measured values received, feedback to the edging device can therefore be made.
- the profile measuring device can also be arranged in front of the trimming device.
- the edging device can be set or adjusted immediately.
- the trimming width can be adjusted depending on the measurement result of the profile measuring device.
- the drawing shows a block diagram of the overall system, which is explained in more detail below.
- the only figure shows a side view of the system.
- the liquid metal in particular steel
- a distributor 2 in a two-roll casting machine 3
- the solidified hot strip 4 is drawn off.
- the steel strip 4a passes through a first driver apparatus 5 and through a profile measuring device 6, which in the
- Embodiment is used before the trimming device 7.
- the steel strip 4a emerging from the trimming device 7 and trimmed on both sides is driven by a second driver apparatus 8 and into a first rolling stand
