Definitions
- the invention relates to a method for longitudinally guiding a rolling stock, in particular a hot-rolled steel strip according to the features of the preamble of claim 1 and a hot rolling mill for carrying out the method according to the features of the preamble of claim. 8
- the rolling stock in a hot rolling mill as it leaves the finishing train, passes through a laminar refrigerating section to a reel section via a roller table.
- the rolling stock In the laminar cooling area, the rolling stock is cooled to a required reel temperature by means of water, in order to achieve a structure structure which is as uniform as possible over the width of the rolling stock and uniform strength properties.
- This temperature profile can be influenced by means of shielding elements for cooling the rolling stock in the sense of equalization by preferably a device arranged along the rolling stock and over the width of the rolling stock.
- Such a device is known from DE 3230866 C2 and DE 199 25 535 A1.
- the rolling stock is transported after leaving the finishing train of a hot rolling mill via a roller table in the direction of a reel and it passes through lying between the finishing train and the reel laminar -Kühl Symposium.
- the rolling stock is guided along and on both sides of the laminar cooling area by at least one lateral guide, which consists of parallel guide bars spaced apart from one another, in such a way that it preferably comprises a cooling device with shielding elements for a liquid above the rolling stock Cooling medium, the entire surface is exposed to the cooling medium substantially.
- a lateral guide which consists of parallel guide bars spaced apart from one another, in such a way that it preferably comprises a cooling device with shielding elements for a liquid above the rolling stock Cooling medium, the entire surface is exposed to the cooling medium substantially.
- the trimming losses of the rolling stock are decisively reduced and consequently the output of rolling stock is increased.
- the rolling stock can be cut along the laminar
- Cooling area to be guided by a plurality of side guides.
- the side guides are, as mentioned, from both sides of the rolling stock, arranged parallel to each other and relatively movable guide rails.
- Setting the at least one side guide to the width of the rolling stock takes place in an embodiment of the invention automatically, by the fact that after leaving the finishing train, the width of the rolling stock is detected by measurement. This is followed by a coarse adjustment of the at least one side guide to the width of the rolling stock and after the head of the rolling stock has passed the side guide, the setting is made to the detected width of the rolling stock.
- the adjustment of the lateral guide transversely to the transport path of the rolling stock can be effected according to the invention as a function of the position of the cooling device preferably arranged above the rolling stock with the shielding elements for a liquid cooling medium.
- the mentioned cooling device can also be aligned with the position of the side guide, always with a view to achieving a temperature profile which remains approximately the width of the rolling stock.
- the hot rolling mill comprises a arranged after the finishing mill of the hot rolling mill laminar cooling section with roller conveyor for transporting the rolling stock, arranged at the end of the roller table reel for winding the rolling stock and preferably arranged above the rolling stock cooling device with shielding elements for a liquid cooling medium.
- at least one lateral guide is arranged along the laminar cooling area. In a further embodiment of the invention, along the laminar
- the width of the rolling stock detecting measuring device is arranged in a further embodiment of the invention, which communicates signal-transmitting with an electronic control of the hot rolling mill.
- the electronic control signal transmitting for example, hydraulic control means for acting on hydraulic piston-cylinder units in combination.
- the piston-cylinder units are the drive means for adjusting the guide rulers to about the width of the rolling stock.
- FIG 3 shows the schematic illustration of the cooling device arranged above the rolling stock in the laminar cooling region of a hot rolling mill with shielding elements for liquid cooling medium in combination with the side guide of a roller table in the front view.
- Hot rolling mill 1 is formed on the output side of the finishing train 2 .
- the rolling stock 5 is transported in the form of a hot-rolled steel strip in the direction 6 of the arrow to a reel 7 and wound thereon. Before winding, the rolling stock 5 is deflected from its preferably horizontal transport direction 6 by means of a driver 8.
- a known side guide 9 is arranged for the rolling stock 5, which, however, serves only the edge flush reels of the rolling stock 5.
- the laminar cooling region 4 can, as shown here, consist of several laminar cooling sections 4.3 over its longitudinal extent, wherein each laminar cooling section 4.3 comprises a cooling device 10 known per se with deflection elements 10.1, see FIG. a. 3, may have.
- FIG. 2 shows the laminar cooling region 4 known from the prior art, but with the difference that between two successive laminar cooling sections 4.3 a side guide 11, consisting of guide rulings 11.1 and 11.2, see FIG. a. 3, and that between the output 2.1 of the finishing train 2 and the input 4.1 of the laminar cooling area 4, a measuring device 12 for detecting the width of the rolling stock 4 is arranged.
- the measuring device 12 is, following the logic, signal-transmitting connected to an electronic control of the hot rolling mill, not shown here for processing the detected measurement result.
- signal transmitting connected to the electronic control are further, for example, not shown here control means for hydraulic piston-cylinder units, which are assigned as adjustment of the existing of a first and second guide ruler 11.1 and 11.2 side guide 11.
- a known cooling device 10 is positioned vertically above the guided on the roller table 3 rolling stock 5.
- the cooling device 10 has shielding elements 10. 1 for a liquid cooling medium 13.
- a guide ruler 11.1 and 11.2 is respectively positioned on both sides of the rolling stock 5. Both guide rulers form the side guide 11 which, as shown in FIG. 2, is arranged between in each case two successive laminar cooling sections 4.3.
- Each of the guide rulers is connected to the free end of the piston rod 14.1 or 15.1 of a preferably hydraulic piston-cylinder unit 14 or 15 in conjunction to be adjusted according to the width of the rolling stock 5 to about this.
