Definitions
- the invention relates to a rolling mill with staggered stands, in particular one Tandem rolling mill, with stand walls spaced on both sides of the rolling line,
- the rollers are stored and removable in their stand windows using chocks are designed.
- Such a tandem rolling mill is known from EP 0 857 521 A1.
- the single ones Rolling stands of this tandem group or similarly staggered stands for reversing or continuous operation are constructed as independent scaffolding units.
- each Roll stand has its own stand construction with two stand walls and these connecting crossbars. From the space required for this individual stand dimensions result inevitably defined scaffold distances, which are kept to a minimum, but which are due to the unfavorably long rolling fittings must be bridged for intermediate guidance of the rolling stock. Farther result inevitably from the relatively large scaffold spacing Reversing times that reduce the production throughput of the rolling mill.
- the width dimension of the roll changing device such as e.g. a transverse transfer platform, also due to the center distance from the roll stand is determined for the rolling stand and determines the length of the entire system.
- the invention has for its object the length of such a staggered Optimize the rolling mill for technological as well as cost-related reasons, i.e. to reduce the spacing between the scaffolding.
- the object is achieved according to the invention in that several stand windows for several chocks in a single stud wall, both on the operating side are also provided on the drive side and that for neighboring Roller pairs each have common crossbeams, the opposite ones Connect and lock the stand walls, are provided.
- This design enables the smallest roller distances between the individual stand stages with several Technological advantages: The rolling and reversing times are reduced. The Intermediate guides of the rolling fittings for the rolling stock are shorter and are in one piece perform. This results in higher operational reliability and better rolling quality due to the shorter bridging lengths. For example With H-profiles, better values for the centerpiece centerline are achieved.
- the uniform stud wall leads to the further advantages that when extended Stand wall of the operating side in the extended end position the roller pairs are exchangeable perpendicular to the direction of extension. This creates space for the waiting room of fresh roller pairs and for worn roller pairs in opposite directions parallel to the rolling line.
- the stand wall and also the roll changing carriage is over rails, optionally arranged in the extension of the base plates or in a different way, transported.
- roller pairs are interchangeable with the rolling fittings.
- roller pairs on a single roller change carriage are transportable.
- the rotary drive for all roller pairs consists of a comb roller gear, which for all roller pairs in one common housing is arranged.
- the regulation for the individual pair of rollers remains unaffected.
- the rolling mill consists of three staggered pairs of rolls 1, 2 and 3, so that one Tandem rolling mill is formed.
- Column walls are on both sides of the rolling line 4 (FIGS. 1 and 2) 5 and 6 with stand windows 7, in which the rollers 8th and 9 of a pair of rollers 1, 2, 3 stored and adjustable by means of chocks 10 are.
- stand windows 7 for the analog number of chocks 10, each with a uniform stud wall 5 on the drive side 11 and a uniform stand wall 6 on the operating side 12 is arranged.
- the stand walls 5 and 6 are each by means of intermediate cross members 13 connected and locked.
- the media feed 19 consists of a media chain 20, which runs between the drive side 11 and the operating side 12.
- Roll armature 21 Between two adjacent pairs of rollers 1, 2 or 2, 3 is a common one Roll armature 21 at an approximately midway between adjacent on the rolling line 4 Roller pairs 1, 2 or 2, 3 lying beam 22 attached.
- roller pairs When the stand wall 6 of the operating side 12 is extended, the roller pairs become 1, 2, 3 in the extended end position 23 shown in FIG. 2 perpendicular to the extending direction 24, i.e. extended in alternating direction 25, worn roller sets 26 extended to the left and new roller sets 27 as shown on the left in the alternating direction 25.
- roller pairs 1, 2, 3 are extended together with the roller fittings 21 or retracted. All pairs of rollers 1, 2, 3 are located on one single roller changing carriage 28.
- the rotary drive for all roller pairs 1, 2 and 3 consists of a comb roller gear, for all roller pairs 1, 2 and 3 in a common housing are arranged (not shown).
- Extension cylinder 29 For the stand wall 6 to be extended on the operating side 12 is a very long one Extension cylinder 29 provided.
