Abstract: A device and a method for producing a continuous strip-shaped composite material. For this purpose, a base material, which is produced using at least one casting machine as a continuous strand, in particular made of steel, and providing at least one cladding material, which is unwound in the form of at least one metal strip by a coil unwinding unit are provided. Subsequently, a slab which has formed by solidification from the strand produced by the casting machine and the metal strip unwound by the coil unwinding unit, in the hot state are brought together, wherein the materials, which are moved in the direction toward one another, formed from the slab and the unwound metal strip are hot rolled, so that a single continuous strip-shaped composite material is thus produced by roll cladding. The base material is continuously cast in the vertical direction in the casting direction.

Abstract: 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.

Abstract: A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.

Abstract: The invention relates to a method for producing a metallic strip or sheet (1), in which the strip or sheet (1) is rolled in a multi-stand rolling mill (11) and is discharged downstream of the last roll stand (14) of the rolling mill (11) in the conveying direction (F), wherein the strip or sheet (1) is cooled in the multi-stand rolling mill (11) and/or downstream of the rolling mill (11) as viewed in conveying direction (F), wherein a temperature of the strip or sheet (1) is measured upstream of the last roll stand (14) of the rolling mill (11) as viewed in conveying direction (F). Based on this measured temperature, a temperature for the strip or sheet (1) at the exit (A) of the last roll stand (14) of the rolling mill (11), is then determined purely by calculation with the aid of a temperature calculation model, with which temperature further processes of the manufacturing method can be controlled or regulated after a comparison with a predetermined reference value.

Abstract: The prediction system of strip chew collects and stores first data and second data as adaptive model construction data. The first data indicates the occurrence or non-occurrence of the strip chew in an object rolling path and the occurrence point of the strip chew. The second data includes information on a preceding rolling path and attribute information on an object strip. The system constructs an adaptive model using the stored adaptive model construction data, and stores the constructed adaptive model as an adapted model. The system collects prediction data similar to the second data. Then, the system inputs the prediction data to the adapted model to predict the occurrence or non-occurrence of the strip chew in the object rolling path and all or some of the occurrence points of the strip chew before the prediction object strip reaches the object rolling path.

Abstract: 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.
