Definitions
- the present invention relates to a rolling method for a metal strip, in particular a steel strip, in a reversing rolling mill with a upstream and a downstream reel, in which the strip is unwound from one of the reels, passes through the reversing rolling mill with a pass reduction of at least 10% and from the other Reel is reeled.
- Such rolling mills and the associated rolling processes are generally known.
- the strip is rolled by repeated back and forth rolling (reversing).
- the strip Before rolling, the strip has a strip temperature which is often above a desired target temperature.
- the object of the present invention is to provide a method by means of which the strip can be brought to the desired rolling temperature as quickly as possible.
- the object is achieved in that the strip is unwound with a strip thickness from the upstream reel with a strip temperature above the set temperature, the reversing roll mill passes through with a throughput speed with a first pass reduction of a maximum of 5% and is wound up by the downstream reel, whereby the throughput speed is selected in such a way that the strip has reached the desired temperature during reeling.
- the stitch decrease should be as small as possible, e.g. B. be only 1%, since the strip temperature is increased again by the forming during rolling. It is optimal if the first pass acceptance is zero, i.e. the rolling mill only acts as a driver in an empty pass.
- the desired rolling temperature can be set even more precisely if the strip is heated in the reels, ie the reversing rolling mill is designed as a so-called Steckel rolling mill.
- the method according to the invention can be used particularly advantageously to carry out both hot rolling and cold rolling of steel in a single rolling mill.
- the strip temperature is particularly advantageously above the so-called GOS line and the setpoint temperature below this line if the metal to be rolled is steel.
- the strip thickness at which the strip temperature is reduced to the target temperature is preferably in the range between 5 and 15 mm.
- Figure 1 is a Steckel mill.
- a Steckel mill consists of a reversing mill 1 with one or two roll stands 2, 3, each of which has a reel 4, 5 arranged upstream and downstream.
- a strip 6 is to be rolled in the Steckel mill, for example from an initial thickness of 50 mm to a final thickness of 1.2 mm.
- the strip 6 is rolled in a reversing manner in the Steckel mill. It is therefore unwound from one of the reels 4, 5, then passes through the reversing rolling mill 1 and finally becomes the other on the other - 3 -
- Reel 4, 5 designed as reel ovens, in which the belt 6 is heated.
- the band 6 is a steel band according to the embodiment.
- the strip 6 is usually hot rolled at the beginning. It therefore has a strip temperature T above the GOS line for steel.
- the belt temperature T is, for example, 1100 ° C.
- the strip 6 is now hot rolled in several passes in the reversing rolling mill 1 until its strip thickness d is between 5 and 15 mm, e.g. B. 10 mm.
- the further rolling to the final thickness of 1.2 mm should be done by cold rolling the strip 6.
- the strip temperature T must be reduced from 1100 ° C to a target temperature T " for cold rolling.
- the target temperature " is below the GOS line for steel and is, for example, 700 ° C.
- the strip temperature T is reduced as follows:
- the strip 6 was wound up on the reel 4 - hereinafter referred to as the upstream reel 4 - during the last pass of hot rolling.
- the strip 6 is now unwound from this upstream reel 4 with its strip temperature T and passes through the reversing rolling mill 1 at a throughput speed v.
- the strip 6 is wound up by the other reel 5 - hereinafter referred to as the downstream reel 5.
- the pass reduction in the reversing mill 1 is set as low as possible for this pass.
- the stitch decrease is zero.
- the roll stands 2, 3 of the reversing rolling mill 1 only act as drivers for the strip 6.
- the throughput speed v can be chosen almost arbitrarily.
- the throughput speed v can also be selected to be very low.
- the strip 6 therefore has sufficient time to cool down to the desired temperature T " on the stretch between the two reels 4, 5.
- the desired temperature T " e.g. B. 700 ° C have reached.
- the reversing rolling mill thus again acts as a normal rolling mill, which reduces the strip thickness d of the strip 6 for each pass, generally by 20 to 50%, in some cases even by 60% per pass. Only the last stitch to the final thickness of - for example - 1.2 mm is usually carried out with a smaller stitch decrease of approx. 10%.
- the throughput speed v of the belt 6 cannot be selected so low that the belt temperature T can be reduced to the desired temperature T in a single pass, two or more such cooling stitches can possibly be carried out before with the further rolling - here cold rolling - is continued.
