Apparatus for manufacturing metal material by rolling
View Patent ↗The invention relates to a device for producing a metallic product ( 1 ) by rolling, comprising: a first area ( 2 ) inside of which slabs are produced by primary shaping; a second area ( 3 ), which is located downstream from the first area ( 2 ) in the direction of flow (F) of the material and inside of which at least one first rolling device ( 4 ) for rolling slabs is arranged; a third area ( 5 ), which is located downstream from the second area ( 3 ) in the direction of flow (F) of the material and inside of which at least one second rolling device ( 6 ) for rolling slabs or the intermediate product produced therefrom is arranged, and; a fourth area ( 7 ), which is located downstream from the third area ( 5 ) in the direction of flow (F) of the material and inside of which at least one aftertreating device ( 8 ) for the rolled material is arranged. In order to increase the economic efficiency of the device, this device is characterized by (having a conveying device ( 9 ) with which the metallic product ( 1 ) can be removed between the second area ( 3 ) and the third area ( 5 ), conveyed and can be fed to the processing process once again between the third area ( 5 ) and the fourth area ( 7 ).
1. Installation for producing rolled metal product ( 1 ), which has:
a first zone ( 2 ), in which slabs are produced by primary forming;
a second zone ( 3 ) downstream of the first zone ( 2 ) in the direction of flow (F) of the material, in which at least a first rolling installation ( 4 ) is installed for rolling the slabs;
a third zone ( 5 ) downstream of the second zone ( 3 ) in the direction of flow (F) of the material, in which at least a second rolling installation ( 6 ) is installed for rolling the slabs or the intermediate product produced from them; and
a fourth zone ( 7 ) downstream of the third zone ( 5 ) in the direction of flow (F) of the material, in which at least one installation ( 8 ) for further processing of the rolled material is installed, comprising a conveyance system ( 9 ) with which the metal stock ( 1 ) can be removed between the second zone ( 3 ) and the third zone ( 5 ) transversely to the direction of flow, conveyed on a rolling table parallel to the direction of flow, and then returned to the treatment process between the third zone ( 5 ) and the fourth zone ( 7 ) transversely to the direction of flow.
2. Installation in accordance with claim 1 , wherein second rolling installation ( 6 ) is a Steckel mill, which has at least one rolling stand ( 10 ) with a first hot box ( 11 ) upstream and a second hot box ( 12 ) downstream of the stand in the direction of flow (F) of the metal rolling stock ( 1 ).
3. Installation in accordance with claim 2 , wherein a shear ( 21 ) is installed downstream of the second hot box ( 12 ) in the direction of flow (F) of the metal rolling stock ( 1 ).
4. Installation in accordance with claim 1 , wherein the further processing installation ( 8 ) comprises a cooling installation ( 13 ) for the rolled product ( 1 ).
5. Installation in accordance with claim 1 , wherein the conveyance system ( 9 ) has a roller table ( 14 ) that is arranged parallel to the second rolling installation ( 6 ).
6. Installation in accordance with claim 1 , wherein the conveyance system ( 9 ) has at least one and preferably two devices ( 15 , 16 ) with which metal rolling stock ( 1 ) can be conveyed transversely to the direction of flow (F) of the material.
7. Installation in accordance with claim 1 , wherein the first zone ( 2 ) has a continuous casting installation ( 17 ).
8. Installation in accordance with claim 1 , wherein a slab storage area ( 18 ) is located in the first zone ( 2 ) or in the second zone ( 3 ) of the installation.
9. Installation in accordance with claim 8 , wherein at least one heating furnace ( 19 ) is arranged between the slab storage area ( 18 ) and the first rolling installation ( 4 ).
10. Installation in accordance with claim 9 , wherein a descaling system ( 20 ) is installed between the one or more heating furnaces ( 19 ) and the first rolling installation ( 4 ).
