Definitions

the invention relates to a rolling mill for wire or bar steel with a continuous fine steel or wire mill, comprising a single-core or multi-core roughing mill with pilot stand, at least one single-core downstream of it, a cooling section with subsequent compensation section and an intermediate stand group, and a finishing train downstream of this with single-core Finishing stand group.
the invention has for its object to improve a rolling mill for wire or bar steel of the type mentioned in such a way that the aforementioned difficulties and technical limits, caused by uneven temperature distribution over the bar length and bar cross-section and the resulting consequences of changing finishing speeds and overcome simple Kind of be balanced.
the object is achieved with the invention in a rolling mill of the type mentioned in the preamble of claim 1 in that between the pilot stand and the intermediate stand group, a first compensation section with a 180 o loop of the rolling stock guided by a first horizontal loop former and between the intermediate stand group and the finishing stand group is arranged with a second compensation section with a 180 o loop of the rolling stock guided through a second horizontal loop former.
the running length of the rolling stock is more than doubled and tripled in some cases with the spatial distance between the roughing train and finishing train unchanged.
the run length between the roughing train and the finishing train, and thus this route can be chosen to be so large that a satisfactory temperature compensation between core and surface is achieved even with the use of a water box in the compensation section with the resulting longer running time of the rolling stock.
the lengthening of the barrel length by forming a horizontal 180 o loop also applies to the section between the intermediate stand group and the finishing train, which ensures that the possible temperature control of the rolling stock by means of the water box ensures that it is at a uniform temperature both over the bar length and also enters the finishing stand group via the cross-section of the bar.
Multi-core roads can be operated according to the invention like single-core, and the top speed can be increased without increasing the disturbance rate.
the rolling stock (30, 30a) leaves the pilot stand (2) of the roughing train (1). Its cross-section fluctuates in a range of approx. 5% due to the inevitable longitudinal tension between the scaffolding in front of it (1) and the pilot scaffold (2). Because these cross-sectional differences in the downstream single-core intermediate line (5) are compensated for by the intermediate frame group (3), this leads to speed differences. These are now compensated in the first 180 o loop (25), which according to the invention is connected upstream of the intermediate scaffold group (3), within the first compensation section (10) which is lengthened as a result.
the first loop former (20) is arranged to be displaceable on rails in the direction of the arrow (22) and is equipped with drive means for displacement. That not shown in detail Drive means is designed, for example, with a pneumatic piston-cylinder unit, the stroke length (22) of which can be approximately one meter.
the run length of the rolling stock (30) between the pilot stand (2) and the finishing train (6) is almost tripled by the rolling stock (30) once in the direction of the arrows (31) as shown in the drawing by right to left and after redirection in the first loop former (20) by 180 o according to arrow (32) again from left to right and then for the third time, again after redirection in second loop former (21) by 180 o , according to arrow ( 33) for the third time.
An embodiment of the invention provides that the pilot stand (2) is arranged downstream of at least one water box (12) in the o of the first 180 -Schlinge (25) compensating section (10) formed, can be carried out with the temperature control of the rolling stock.
a further embodiment of the invention provides that the intermediate stand group (3) is arranged downstream of at least one water box (13) within the o from the second 180 -Schlinge (26) compensating section (11) formed.
This water box (13) has a sufficiently long running distance up to the inlet into the finishing stand (4) of the finishing train (6), so that the required temperature compensation between the core and the surface of the rolling stock is ensured.
a particularly expedient arrangement results from the fact that the intermediate stand group (3), the loop formers (20, 21) and the 180 o loops (25, 26) extending between them are offset laterally next to the roughing train (1) and the finishing train ( 4) connecting production line (xx) are arranged.
the last roughing mill stand can also be designed as a pilot stand and at the same time the two finishing lines (6, 6a) can work as fixed stands at constant speed, with all speed differences, in particular as a result of cross-sectional fluctuations in the pilot stand and the resulting length differences in the 180 o - Loop tables (25, 26, 25a, 26a) can be caught.
