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.

Furnace for heating metal strips, and device and method for producing metal strips by continuous casting and rolling

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.

Method for producing a continuous strip-shaped composite material

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.

Method and device for producing a continuous strip-shaped composite material

A device and method for producing a continuous strip-shaped composite material including a base material of metal, which is unwound in the form of a metal strip by a first coil-unwinding apparatus, and at least one cladding material of metal, which is unwound in the form of a metal strip by a second coil-unwinding apparatus. The metal base and cladding metal strips unwound by the respective coil-unwinding apparatuses are brought together in the hot state of at least 720 degrees Celsius. The unwound base and cladding metal strips brought toward each other and are joined by hot-rolling such that a single continuous strip-shaped composite material is thereby formed by roll cladding such that the composite material includes the base material and the cladding material.

A device for changing a blade on shears, in particular for a rolled band, and to such shears in which a blade can be fixed to at least one blade support automatically by a tie bar pretensioned by a force accumulator. The device includes at least one adjusting element which can be actuated in order to release the blade from the blade support such that the tie rod is moved in an axial direction against the tie rod pretension. The adjusting element can be arranged on an outer face of the blade support or outside of the blade support.

A method for producing a metallic strip by continuous casting-rolling, wherein a slab is cast in a casting machine and then sent to a finishing mill located downstream, relative to the transport direction of the strip. In the event that the transport of the slab or strip comes to a complete or substantially complete standstill, the following steps are carried out: (a) cutting through the strip at a first point; (b) cutting through the strip at a second point that is 0.1-5.0 m upstream from the first point; (c) removing the cut-out piece of strip to create a gap in the strip; (d) conveying new strip material into the area of the gap from the area located upstream of the first point; and (e) cutting off pieces of the new strip material conveyed from upstream according to step (d) and removing the pieces from the transport line.

The present invention relates to a device () for removing a sample () from a coil (), comprising at least one bottom roll unit () for supporting the coil () during removal of the samples, at least one contact roll unit () pressable against an outer surface of the coil (), and at least one strip binding device for binding the coil () supported on the at least one bottom roll unit (). The present invention further relates to a device for removing a sample () from a coil (), comprising a deflection device () for deflecting a material beginning () of the coil () from a beneath located layer (), wherein the deflection device is so formed that the strip beginning only elastically deflected from the beneath layer (). The invention also relates to corresponding methods.

Method and device for removing a sample from a coil

The invention relates to a method for expanding the use of a coiling and uncoiling station (coilbox) located between the roughing train and the finishing train for rolled strip material in hot-rolling mills. The use of said coilbox is expanded by impinging the coil that is to be uncoiled with a pressing force (F) which acts in the direction of the roller table () and/or placing the coil in a depression of the roller table in order to process smaller coil weights in a spikeless coilbox, and/or by combining, in a chronological and weight-related manner, the active transfer and passive transfer of a coil from a first coiling station to a second coiling station in order to increase the throughput especially at average coil weights in a spikeless coilbox, and/or by supplying heat to the strip upstream or downstream of the spikeless coilbox and/or thermally insulating the strip or the coilbox in order to variably increase and homogenize the strip temperature. The invention further relates to a correspondingly equipped device for carrying out said method.
