Definitions

  • Rolling mill for hot rolling of metal, in particular aluminum and hot rolling
  • the invention relates to a rolling mill for hot rolling of metal, in particular of aluminum, with a hot strip mill with a roughing mill and a finishing train and a corresponding hot rolling process.
  • the classic or conventional layout 100 for such a hot rolling mill which is illustrated by way of example with FIG. 3, is composed of the essential processing stations furnace area 102, rolling train 103 and possibly finishing (finishing).
  • An aluminum ingot 117 is brought to rolling temperature in ovens 120, 121-for example hearth or pusher furnaces-and pre-rolled in the stand-alone roughing stand 108 of the roughing train 104 after passing through an upsetting stand 107.
  • the rough rolling product is scooped up with a first scissors 122.
  • the board 119 is scooped up at the end and beginning of the board, between these two Schopfscheren 122, 125 a certain Distance is available.
  • the finish rolled strip 105 in the finishing train 105 runs along edging shears 126 and is reeled up by means of driver rollers 127 by a reel device 114.
  • Such a plant with furnace area 102 and rolling mills 103 can have enormous lengths.
  • the length x of a furnace area 102 may be 130 m
  • the distance between the roughing stand 108 and the first stand 111 of the finishing train may be 240 m, for example, the distances influencing the achievable coil sizes.
  • the run takes place of the rolling stock through the rolling mill plant with the help of extensive transport and leadership facilities, such as roller tables.
  • Such rolling mills tend to work more economically with larger coil dimensions.
  • the present invention seeks to provide a more compact in its design mill for hot rolling of metal, especially aluminum, with the transport spaces between the individual processing stations (furnace area, roughing, finish rolling) are reduced.
  • a hot rolling process is to be created which allows rolling from strip to final roll thickness with a compact design of the rolling mill with high efficiency.
  • the basic idea of the invention is that the compact design of the rolling mill or of the hot strip mill is created jointly by the consistent use of tandem rolling in the rough rolling mill, in the finishing train or in the rough rolling mill and finishing train.
  • the roughing train alone and / or the finishing train alone or the roughing and finishing train together are tandem mills, ie plant sections in which the mills stand in tandem (tandem arrangement). Due to the resulting compact construction significant parts of the otherwise necessary roller tables can be omitted, thereby reducing the investment costs.
  • the rough rolling mill is designed as a tandem mill, wherein it may comprise two rough rolling mills arranged one behind the other. This roughing mill is preferably reversing.
  • the roughing mill can be one-armed. She then works with the finishing train in tandem operation. The distance between the pre-rolling and finish-rolling lines is selected so that all stands can roll at the same time.
  • finishing train has two reels and the finishing train is operated in tandem.
  • the proposed layout is not only suitable for new buildings, but also for modernization of existing plants.
  • it is achieved by the tandem rolling in the roughing and / or finishing mill that smaller plants, on which previously only smaller tonnages and smaller coils were produced, their further processing is partially uneconomic, can be converted so that the length of the roller table is the same Bund weights (tape lengths) can be increased, which increases productivity.
  • two roughing stands are provided in the rough rolling mill and two finishing rolling stands in the finishing mill, each operating in tandem operation.
  • a roll stand can be saved in this layout with four stands compared to the classic layout with five stands.
  • the two roughing mills can be designed as cost-saving duo-scaffolding according to the new layout, while the finishing mills are four-high (quarto) scaffolding.
  • Fig. 1 shows the compact plant layout of the rolling mill for rolling aluminum according to the invention
  • Fig. 2 shows the implementation of the rolling process in a rolling mill according to the invention
  • Fig. 3 for comparison, the plant layout of a conventional hot strip mill for aluminum.
  • Fig. 1 shows the new compact hot rolling mill layout 1 for aluminum.
  • the comparison with the layout 100 according to the prior art shown in FIG. 3 illustrates the compactness of the system according to the invention.
  • the plant also consists of a furnace area 2 and the rolling mill 3 with a roughing and a finishing train (4, 5).
  • the roughing train 4 is composed of two rough rolling mills 8, 9 arranged one behind the other, which work reversibly in tandem operation. This is followed by flying shears 10 to prepare for finish rolling.
  • the finish rolling is carried out in the finishing train 5, which consists of two closely arranged quarto stands 11, 12, wherein the belt 13 can be reversibly rolled.
  • a first reeling device 15 is arranged in front of the finishing train 5. 16 denotes a trimming scissors.
  • the overall length of the system according to the invention according to FIG. 1 is significantly shortened, which in particular relates to the distance between the end of the roughing train 4 and the first stand 11 of the finishing train 5.
  • the proposed system is very compact, while at the same time the production of high bundle weights is possible.
  • only one flying scissors 10 is arranged between the roughing and finish rolling lines 4, 5.
  • the method itself is illustrated by means of FIG.
  • For hot rolling a hot aluminum ingot 17 is placed on a roller table 18 and transported in the roughing Trandem Avenue 4 and there reversing in the two roughing stands 8, 9 rolled out in tandem, for example, three times back and forth, as shown by the arrows a and designated rolling step I.
  • the rough rolling product is rolled reversibly by tandem rolling in finish rolling stands 11, 12 between the two reeling devices 14, 15.
  • the strip 13 is wound after the first rolling operation with simultaneous participation of the two finishing stands 11, 12 with the second coiler 14.
  • the end of the tape is scooped with a flying scissors 10.
  • the direction of rotation of the respective upper and lower rollers of the stands 11, 12 is changed (arrow b) and the belt 13 again retracted into the finishing mills 11, 12.
  • the tape 13 is unwound from the first coiler 15 and simultaneously unwound from the second coiler 14 and then reversed again (arrow c).
  • the reversing process can be repeated according to the desired final thickness of the strip 13.

Abstract

L'invention concerne un laminoir (1) destiné au laminage de métal, notamment d'aluminium. Ce laminoir comprend un train à feuillards à chaud (3) équipé d'un train d'ébauchage (4) et d'un train finisseur (5). L'invention vise à améliorer ce laminoir de telle façon qu'il soit plus compact ou que les installations actuelles déjà compactes soient plus productives. A cet effet, le train d'ébauchage (4) est réalisé sous la forme d'un train tandem dans lequel la matière à laminer est laminée en mode tandem pour une utilisation commune d'au moins deux cages de laminoirs (8, 9). En variante ou simultanément, le train d'ébauchage (4) et le train finisseur (5) fonctionnent comme un train tandem et, dans le cas d'une utilisation commune des cages des trains d'ébauchage et finisseur, le produit est laminé en mode tandem. Dans le train finisseur, on peut également procéder à un laminage en mode tandem à marche renversée.
