A device for producing hot-rolled metal strips has a casting machine that produces and transports slabs in a transport line of the casting machine. A rolling mill forms the slabs into corresponding metal strips during transport along a transport line of the rolling mill. A combination transport and temperature-influencing device is arranged between the casting machine and the rolling mill transports the slabs at least along the transport line of the rolling mill, feeds the slabs to the rolling mill and sets the temperature of the slabs to a rolling temperature. A surface device is arranged between the casting machine and the combination transport and temperature-influencing device and processes and/or treats and/or inspects at least one of the surfaces of the slabs. A temperature-influencing device is arranged between the casting machine and the combination transport and temperature-influencing device and modifies the temperature of the slabs.

A framework cooler (20) for cooling a steel strip (50), installed in a roller framework (11), in place of the work rolls (5) and their associated installation pieces (5a and 5b). The framework cooler (20) is sized to be installed into the roller framework (11) through the operator-side roller stands (1) of the roller framework (11). The cooler (20) includes a lower (21b) and an upper water tank (21a), each having a connection (22) for a coolant, and includes a plurality of cooling nozzles (23), or cooling tubes (23a) arranged in the depth direction (T) of the framework cooler (20) or at least one cooling slot (24) extending in the depth direction (T). The bottom and top sides of the steel strip (50) may be cooled.

A method and a device for producing a continuous strip-shaped composite material. The device has at least one first casting machine, using which a continuous strand is produced, in particular from steel, at least one rolling stand, which is arranged in line with the first casting machine and downstream thereof. A fully solidified slab of the strand produced using the first casting machine can be hot rolled, and at least one second casting machine, using which a further continuous strand is produced from metal. Between the casting machines, on the one hand, and the rolling stand, on the other hand, a merging unit is arranged, by means of which the slabs can be moved in the direction toward each other in the hot state. The rolling stand is designed as a roll-cladding unit, by which a composite formed from the merged slabs can be hot rolled.

A meandering control device and hot rolling equipment suppress a meandering amount of a hot-rolled steel strip. A roll opening degree difference between an operation side and a driving side in an i-th rolling machine computed in a leveling control computation step (step S3) in the meandering control method, satisfies the roll opening degree difference between the operation side and the driving side in the i-th rolling machine (Fi) by Expressions (1), (2), and (3) in a control section j, in a case where the control section j is set when a tail end portion (Sa) of a traveling hot-rolled steel strip (10) is present between a j-th (j≤i−1) rolling machine (Fj) and a (j+1)th rolling machine (Fj+1) counting from a rolling machine (F1) installed on a most upstream side.

A plate thickness control device controlling plate thickness of a hot rolling mill that includes a rolling stand. The plate thickness control device includes: a pyrometer disposed on an entry side of the rolling stand; a difference calculation part that outputs a difference temperature between a lock-on temperature of the plate-to-be-rolled measured by the pyrometer and a measurement value of a portion other than a tip portion of the plate-to-be-rolled measured by the pyrometer; a tracking part that transfers the difference temperature from the position of the pyrometer to immediately below the rolling stand based on plate speed of the plate-to-be-rolled; and a computation part that calculates a screw-down amount of the rolling stand based on the difference temperature transmitted from the tracking part.
