A Steckel mill has a reversing unit for rolling a rolled product and winding furnaces arranged on the entrance side and exit side of the reversing unit. When rolling the rolled product in a region of a head of the rolled product, a target thickness of the rolled product is ignored, while measuring a current thickness and/or a hardness of the rolled product and comparing this with a setpoint value. One the measured variable reaches or is below the setpoint value, the reversing unit is operated with a view to achieving the target thickness of the rolled product. The Steckel mill is operated to allow for rolling of a cold, non-rollable piece of the rolled product, so that malfunctions are avoided and the usable part of the rolled product is as large as possible.

According to an embodiment of the invention, a rolling equipment includes two coiler furnaces; a plurality of mill stands provided between the two coiler furnaces, the plurality of mill stands being for reverse rolling; and an induction heater provided between the plurality of mill stands, the induction heater implementing a heated temperature increase in a designated reverse rolling or in each reverse rolling, the heated temperature increase being in a hot strip longitudinal direction and width direction. Thus, the hot strip temperature distribution can be improved.

A furnace for heating metal strips, and to a device and a method for producing metal strips by continuous casting and rolling. The device includes a casting machine, a furnace through which a metal strip can be transported in a conveying direction, a first external cutting apparatus and a second external cutting apparatus, the first external cutting apparatus being upstream of the furnace and the second external cutting apparatus being downstream of the furnace, in the conveying direction of the metal strip, and at least one rolling mill. A first internal cutting apparatus and a second internal cutting apparatus are provided inside the furnace. A segment of the metal strip between said internal cutting apparatuses can be separated by actuating the latter.

The invention relates to a cooling method for a rolling ingot of aluminium alloy after metallurgical homogenization heat treatment of said ingot and before hot rolling, characterized in that cooling by 30 to 150 C. is performed at a rate of 150 to 500 C./h, with a homogeneity of less than 40 C. throughout the treated portion of the ingot.

The invention also relates to the facility allowing use of said method and said implementation.

An aluminium strip for manufacturing a package of a solid, liquid or gaseous product consisting of an aluminium alloy. The aluminium strip has at least a one-sided or two-sided antibacterial coating. The object of proposing an aluminium strip consisting of an aluminium alloy with at least a one-sided or two-sided antibacterial coating, which can be more easily produced with very good antibacterial effect of the coating and can already provide very good antibacterial properties at extremely low concentrations of the antibacterial substance, is achieved by the antibacterial coating containing ZnMoO.sub.4 as the antibacterial substance.

Rolling method to produce a metal strip (P) in coil-to-coil, semi-endless or endless mode, in a rolling plant (10) comprising: a continuous casting device (11) to produce slabs; a furnace (16) configured to maintain the slabs at a certain temperature and/or to heat the slabs; at least one roughing stand (25) to reduce the thickness of the slabs and obtain an intermediate rolled product; a plurality of finishing stands (31) to reduce the thickness of the intermediate rolled product and obtain the strip (P); a rapid heating device (28) interposed between the at least one roughing stand (25) and the plurality of finishing stands (31) to heat the intermediate rolled product in each operating mode, so that the temperature of the strip (P) in correspondence with the outlet of the last finishing stand (31) is comprised between 830 C. and 860 C.

Method for rolling metal products comprising a plurality of sequential rolling passes during which a metal product (P) is rolled. The method comprises a first rolling pass of the metal product (P) to obtain a first intermediate product (P1), a second rolling pass of the first intermediate product (P1) to obtain a second intermediate product (P2), a third rolling pass of the second intermediate product (P2) to obtain a third intermediate product (P3), a fourth rolling pass of the third intermediate product (P3) to obtain a final rolled product (L).

A method for assigning surplus slabs in slab yards to orders includes loading slab pre-yards of a plurality of production lines with surplus slabs, describing the assignment of the surplus slabs to the orders with a mathematical model, grouping order data and slab data based on steel grades, obtaining an assignment scheme for the surplus slabs and the orders in each group with a mixed scatter search algorithm, and assigning the surplus slabs to the orders using the assignment scheme. If a surplus slab is in a pre-yard of a production line associated with an order the surplus slab is assigned to, the slab is moved using a crane to the production line. Otherwise, the slab is moved to the pre-yard associated with the production line, and then moved using a crane to the production line. The slab is then heated and rolled by the production line.

A method of hot forming an aluminum alloy component may include heating the aluminum alloy component in a heating furnace to a solutionizing temperature, cooling the aluminum alloy component to a desired forming temperature, deforming the aluminum alloy component into a desired shape in a forming device while the aluminum alloy component is at the desired forming temperature, maintaining a constant temperature during the deformation of the aluminum alloy component, and quenching the aluminum alloy component to a low temperature below a solvus temperature.
