To accomplish the object of providing a method of and an apparatus for optimally cooling the rolls of a roll stand, where energy considerations, such as the minimization of necessary cooling fluid flow and cooling fluid pressure, and incident design and manufacturing costs, must be taken into account, the invention proposes that the rolls are cooled with a combination of high- and low-pressure cooling.

Disclosed is a strip coiler for coiling a metal strip (20), comprising a coiling mandrel (21), pressing rollers (26) associated with the coiling mandrel (21), and adjustable deflection shells (28) for pressing the leading edge (24) of the metal strip (20) against the coiling mandrel (21). The disclosed strip coiler is characterized in that at least one of the deflection shells (28) has a tip (22) which is adjustable relative to the deflection shell (28).

The invention is directed to a cylindrical milling cutter whose cylindrical body is provided with grooves which extend along its length at a distance from one another and at an angle to the longitudinal axis, and indexable cutting inserts, particularly coated carbide cutting inserts, are arranged in these grooves. For substantially preventing axial forces acting on the milling cutter or on the material to be machined, it is proposed either that the grooves and therefore the knife edges of the indexable cutting inserts are portionally oriented at different angles, these angles being selected such that the axial forces occurring in one portion during the machining process are neutralized or reduced in a defined manner by the axial forces occurring in the adjacent portion, or that the indexable cutting inserts are alternately arranged or oriented in the grooves in such a way that the axial force caused by one indexable cutting insert during the machining process is neutralized by the axial force caused by the adjacent indexable cutting insert.

The invention relates to a device for producing a metal strip (1) by continuous casting, using a casting machine (2) in which a slab (3), preferably a thin slab, is cast. At least one milling machine (4) is arranged in the direction of transport (F) of the slab (3) behind the casting machine (2). At least one surface of the slab (3), preferably two surfaces which are opposite to each other, can be milled in said milling device. According to the invention, in order to keep the temperature loss to a minimum when the slab is machined and/or processed, at least one milling cutter (5, 6) of the milling machine (4), preferably the entire milling machine (4), is arranged in a displaceable machine in the direction (Q) perpendicular to the direction of transport (F) of the slab (3). The invention also relates to a method for producing a metal strip.

In a method and a device for descaling a metal strip, the metal strip is guided in a transport direction from a first roll stand to a second roll stand. A descaling device is positioned between the first and second roll stands. A descaling liquid is sprayed onto the metal strip from a working distance relative to the metal strip via the descaling device. The metal strip is moved at the location of the descaling device by a forced deflection amount in a direction transverse to the transport direction via an advancing element. A position of the descaling device is adjusted based on the forced deflection amount such that the working distance stays the same.

A planarity measuring roller is constructed as a loop lifter which is adjustable relative to a rolled strip. The loop lifter includes a plurality of measuring zones located next to one another over the width of the rolled strip. Each measuring zone includes a rotatably mounted individual measuring roller which is pivotable in a clockwise direction and interacts with a force measuring device. Each measuring roller is mounted in a pivotable housing-like lever frame. The pivot point of each lever frame, the point of rotation of the corresponding measuring roller and a force introduction point of the force measuring device arranged underneath of the pivot point of the lever frame form an approximately isosceles triangle.

The invention relates to a winder (1) for winding strips (2), in particular thin metal strips, comprising a coiler drum (3) which is arranged such that it can rotate about a rotational axis (4), and at least one pivoting arm (5) which is arranged such that it can pivot about an axis (6) and which has at least one deflection plate (7) and at least one pressure roller (8), which deflect and press the strip (2) which is to be wound. In order to improve, in particular, the winding of thin strips, the invention provides for the at least one pressure roller (8) to be assigned at least one movement means (9), by way of which the pressure roller (8) can be moved relative to the pivoting arm (5).

The invention relates to a device (1) for measuring the width (B) and/or the position of a metal strip (2) or a slab, which has at least two measuring systems (3, 4), with each located on a side (5, 6) of the metal strip (2) or the slab, wherein each measuring system (3, 4) has a sensor (7) designed to detect the lateral end (8, 9) of the metal strip (2). To make the measuring device robust and to enable dynamic measurement, according to the invention the sensor (7) is located on a moving element (10) with which it can be moved in a straight line in a direction (Q) at right angles to the longitudinal direction (L) of the metal strip (2).

The invention relates to a device for the hot-dip coating of a metal strip (1), more particularly of a steel band, in which the metal strip (1) is guided vertically through a container (3) containing the molten coating metal (2) and through an upstream guide channel (6), in the vicinity of which, on both sides of the metal strip (1), are arranged at least two inductors (8) for generating an electromagnetic field for holding the coating metal (2) in the container (3), a furnace chamber (9), which contains guide means and has a protective gas atmosphere, being located upstream of the guide channel (6). In order to ensure a good, durable seal between the guide channel (6) and the furnace chamber (9) under the established conditions, the invention proposes that a gas-tight, heat-resistant and flexible seal (13) be arranged between the furnace chamber (9) and the guide channel (6).
