Definitions
- the invention relates to a system for hot rolling strip or sheet-shaped rolling stock with two reversing stands arranged directly behind one another between a front and a rear reversing reel.
- a roughing stand and a finishing stand separately are usually used.
- the roller roughness and the roller diameter can thus be adapted to the particular requirements of the shaping process.
- the disadvantage must be accepted that the capacity of the roughing stand is poorly utilized and that on the one hand a large temperature loss is unavoidable due to the conveyance of the rolling stock from the roughing stand to the finishing stand and on the other hand because of the high number of individual passes required in the finishing stand, even if before and Holding furnaces are provided behind the finishing stand.
- the consequence of this is that, particularly in the case of thin hot strips, the required final rolling temperatures can hardly be maintained, especially with higher coil weights.
- the strips to be rolled can only be descaled in one or very few passes in order to avoid higher temperature losses. Impairment of the quality of the belt surface can therefore hardly be prevented.
- a reduction in the strip thickness that can be achieved is accepted because, due to the high temperature losses, the strip temperature that is still permissible is already reached with strip thicknesses of up to approximately 2 mm. It does not need to be explained in more detail that there is also a limited capacity of up to a maximum of 450,000 t / year.
- FR-PS 1 132 772 To avoid high temperature losses, it is already known (FR-PS 1 132 772) to arrange two or three stands immediately one behind the other, so that the rolling stock is rolled in the stands at the same time, which means that fewer passes are necessary.
- a disadvantage of these reversing stands, which are arranged directly one behind the other, is that, due to the similarity of the stands, no adjustment of the roll diameter and the roughness of the rolls to the respective requirements is possible.
- the invention is therefore based on the object to avoid these deficiencies and to improve a system for hot rolling strip or sheet-shaped rolling stock of the type described in such a way that an economical production of thin hot strip with a good surface quality is guaranteed even for medium and high coil weights and the capacity can be increased significantly.
- the invention solves this problem in that a roughing stand is provided directly in front of the front reversing reel and in that the stands can be converted from an optional individual operation to a joint operation.
- the rolling stock is brought to the desired rolling temperature in an oven 1.
- the heated rolling stock is then descaled in a scale washer 2 before it is fed to the roll stands, a roughing stand 3 and two reversing stands 4 serving as finishing stands.
- Two reversing reels 5 and 6 are arranged upstream and downstream of these reversing stands 4, the reversing reels 5 and 6 being able to be equipped either with a heatable mandrel or with a heating hood in order to avoid higher temperature losses.
- the rolled hot strip is then wound on a reel 7.
- a cropping shear 8 is provided between the rear reversing stand 4 and the rear reversing reel 6 for trimming the beginning and ends of the tape.
- the selected arrangement of the cropping shears 8 offers the considerable advantage that both the beginning and the end of the band can be additionally trimmed after the finished stitches.
- the rolling stock is transported in the usual way on roller tables 9, the driven reels 10 of a driver 11 being arranged upstream of the reels 5, 6 and 7.
- the system shown for hot rolling strip or sheet-shaped rolling stock differs from conventional hot rolling systems of a comparable type primarily in that the roughing stand 3 is positioned in front of the two reversing stands 4 serving as finishing stands with the smallest possible distance, so that between the roughing stand 3 and the front reversing stand 4 the reversing reel 5 just finds space.
- This not only makes the usual roller table for receiving the tape for the preliminary stitches unnecessary, but also gives the advantage that all scaffolding can be switched from an individual operation to a common one Operation or a tandem operation can be changed.
