Abstract
The present invention relates to for producing the milling train of band, equipment includes the heater and the second cutter of a casting machine for being used for continuous casting steel billet, crystallizer, two rolling-mill housing, the first cutter, induction type or roller bottom stove form, it is the mm finishing mill unit with each and every one more finishing stands after the second cutter, it is a cooling section after mm finishing mill unit, cutter is installed with after before the cooling section, the coiling machine of form known is installed in equipment end.There is a kind of milling train for being used for producing band of final thickness it is an object of the invention to provide band after last rolling-mill housing.
Description
Technical Field
The invention relates to a rolling mill for producing strip.
Background
The continuous rolling of steel strip with casting residual heat has long been known. This method is increasingly applicable at higher casting speeds. The slab is first produced in a continuous casting machine, flows vertically downwards out of the mold, is then turned into the horizontal direction, and the still hot strip is then fed to the rolling train. The thickness of the slab is reduced in the rolling stands of the rolling train until a strip having the desired thickness is produced.
Disclosure of Invention
The object of the invention is to provide a rolling mill for producing strip, in which the strip has a final thickness after the last rolling stand.
Rolling mill for the production of strip, characterized in that the plant comprises a casting machine for the continuous casting of slabs, a crystallizer, two rolling stands, a first shear, heating means in the form of induction or roller hearth furnaces, and a second shear, that the second shear is followed by a finishing mill group with a plurality of finishing stands, that the finishing mill group is followed by a cooling section, in front of and behind which the shears are mounted, and that at the end of the plant a coiler of known form is mounted.
A rolling mill for producing strip as described above, characterized in that an inter-stand cooling device is installed between the stands.

Detailed Description
Fig. 1 shows a schematic view of a rolling mill for producing a strip 1. The plant comprises a casting machine 2 for continuous casting of slabs 3. The slab 3 flows vertically downwards from the crystallizer 9 and is then deflected in a known manner to the horizontal. Arranged here is a first rolling mill train 4 with two rolling stands 6. This is followed by a first shear 10, a heating device 11 in the form of an induction or roller hearth furnace, and a second shear 12. The second shear 12 is followed by a finishing train 5 with a plurality of finishing stands 7, and the finishing train 5 is followed by a cooling section 13, to which shears 14 and 15 are attached before and after. At the end of the apparatus is mounted a coiler 16 of known form. In order to optimize the cooling effect of the finished strip in the case of open stands and to ensure early cooling of the finished strip, an inter-stand cooling device 18 is installed between the last stands. This may improve product characteristics. The required final rolling temperature of the finished strip is monitored with a pyrometer after the last active roll stand.
Claims (2)
