Definitions
- the invention relates to a working method for rolling finished profiles according to the generic term of claim 1 (see e.g. EP-A-0 653 253).
- Rolling sheet pile sections has so far been reversing working rolling mills with stand-alone stands and Free run of the roll stand carried out because of the variety of large calibers necessary for the pre-rolling of such profiles
- Reversing mill stands with the large number of form calibers large bale lengths of the rollers required (GB 2 037 205 A).
- These big scaffolds and the rollers themselves and the necessary manipulation devices for the introduction of the rolling stock into the different calibers is very complex, require a large amount of space and are proportionate low throughput.
- the large quantities of the rolling stock even lead to relatively long rolling times reversing rollers and practically do not allow such To operate systems in working cycle sequence with a continuous caster. It is therefore in a combined operation between the continuous caster and rolling mill relatively large intermediate storage necessary.
- the object of the invention is the working method after the aforementioned, not previously published patent application for rolling To improve sheet piling profiles so that the disadvantages mentioned avoided and the difficulties eliminated and thus the rolling of sheet piling profiles both with a U cross section and that of a Z cross section in all sizes and with good performances the roll stand arrangement is made possible.
- This object is achieved in a generic method in that the Horizontal stand of the roughing group and / or that Compression intermediate scaffolding of the compact tandem scaffolding group, two each Have caliber, and that the output-side universal frame the compact tandem scaffolding group one or more duo horizontal scaffolding are subordinated with caliber rollers, and that when rolling with this scaffolding arrangement the width adjustment and a shape adjustment a pre-profile with an H cross-section while reducing of the cross section in the roughing group and the further reduction of the cross section with preforming of the profile ends for the lock formation in the compact tandem scaffolding group and the final completion the lock of the profile in the calibres of the duo horizontal frames he follows.
- a heating furnace behind a heating furnace is WO, too a reheating furnace directly connected to the continuous casting device can be, the warm exit extrusion profiles at rolling temperature heated, a roller table RG1 arranged to the roughing stand group leads, the input side of a vertical duo scaffolding VDG and on the output side consists of a horizontal dual scaffold HDG.
- This group of roughing stands is in the same rolling line WL1 a roller table RG2 downstream.
- a cross transport device QT leads to a parallel roller table RG3, which in a second rolling line WL2 leads to the compact tandem stand group from an input-side universal scaffold EUG, an intermediate compression scaffold SZG and an exit-side universal scaffold AUG and there is a roller table RG4, which is located in the same rolling line WL2 to the duo horizontal stands arranged one behind the other DHG1, DHG2 and DHG3 leads with caliber rolls are equipped.
- the preliminary profile VP is in the vertical duo scaffold VDG compressed in the first stitch 1 and in a subsequent stitch 2 in the Choice caliber WKI of the horizontal duo stand HDG shaped and then in a reversing stitch R3 and then in a following stitch 4 in Election caliber WKII reduced. It then follows in a continuous sequence three stitches 5, 6 and 7 through the universal frame on the input side EUG, the compression intermediate scaffold SZG and the universal scaffold on the exit side AUG of the compact tandem scaffolding group, in the reverse Direction and sequence of the scaffolding the reversing stitches Connect R8, R9 and R10, this is followed by another run the following stitches 11, 12 and 13 through the mentioned row of scaffolds.
- the finished basic shape achieved with these tandem sequences the sheet pile profile is made in subsequent stitches 14 and 15 in the calibers of the DHGI duo horizontal frameworks and DHGII finished by final shaping of the lock ends.
- the pre-profile VP is also in one first stitch 1 in the vertical duo scaffold VDG and then in a follow-up stitch 2 through the horizontal duo stand HDG of the roughing group pre-formed in their choice caliber WKI.
- This form is in a reversing stitch R3 and another stitch 4 through the dial caliber WKII reduced and then in a sequence 5, 6 and 7 through the EUG universal scaffold on the entrance side, the compression intermediate scaffold SZG and the exit-side universal scaffold AUG of the compact tandem scaffold group and a subsequent reversing stitch sequence R8, R9 and R10 and a connection stitch 11 through the input side Universal scaffold EUG further reduced and then, finally, in a stitch 12 through the second choice caliber of the compression intermediate frame SZG preformed.
- the finished sheet piling profile is immediately afterwards in a continuous sequence 13, 14, 15 in the duo horizontal stands DHGI, DHGII and DHGIII finished rolled.
