A hot-rolling stand () for a hot-rolling mill comprises an adjusting device (), which is intended for receiving a pair of work rolls () and for positioning work rolls () of the pair of work rolls () in relation to one another to define a roll gap. In order to create a hot-rolling stand () that can be adapted as flexibly as possible, the adjusting device () is designed to interchangeably accommodate, in the pair of work rolls (), different roll diameter ranges by means of mutually complementary work rolls ().

Hot-rolling stand for a hot-rolling mill and for producing a flat metal product, hot-rolling mill and method for operating a hot-rolling mill

A modular rolling train, particularly a hot rolling train, preferably in conjunction with an upstream casting facility, and a method for operating a modular rolling train are described. The rolling train is standardized and modularized by dividing the rolling train into discrete units n and by modularization of the discrete units. The rolling train can be flexibly adapted to new requirements by exchanging a module.

A device and a method are described by which the process control, in particular temperature control, of a metal product passed through along a single running-through line is flexibly influenced by means of at least two adjacent segments. By exchanging segments, the process control can be adapted quickly and flexibly to a wide variety of metal products.

In the case of a drive arrangement for a rolling mill, comprising at least one drive motor (M), a main gear mechanism (HG), a pinion gear mechanism (KWG), a rolling stand (G) with working rolls (AW), and the spindles, couplings and the like which connect these components, the main gear mechanism (HG) is a single-stage one and the drive axis (AN) is spaced apart from the output axis (AB) by an upwardly directed, vertical spacing (vA).

Drive arrangement for rolling mill

The invention relates to a production method for producing, on a production installation (), flat products, also of a large width, from continuously cast slabs having a large or medium thickness or from thin slabs. Said production installation is comprised of a single or multiple stand blooming train (), of a roller table (), which is provided for conveying the rolling stock and, optionally for oscillating, of a roller table section () with hinged heat-insulating covering hoods. The production installation is also comprised of a straightening unit () for straightening the pre-strips, of an, in particular, inductive heating installation () for effecting the controlled heating of the pre-strips to a defined temperature over the length and width of the pre-strips, of a multiple-stand finishing train (), of a delivery roller table with devices () for cooling the hot rolled strip, and of subsequently arranged coiling machines () for coiling the finished strip. In the single or two-stand blooming train (), one or more slabs comprised of carbon steels having an average carbon content of approximately 0.2 to 0.8% or of alloyed case hardening steels or heat-treatable steels are rolled on the roller table () to form one or more pre-strips. Said rolling is carried out in two stages with a pause between the same for effecting an intermediate cooling by oscillation. The pre-strips are heated over the length and width thereof to a defined temperature by the combined action of the covering hoods and heating installation, and are rolled in a multiple-stand finishing train () in the two-phase region in order to form thin high-strength finished strips.

Production method and installation for producing thin flat products

A hot rolling installation should be constructed and able to be operated so that strips of materials, which can be shaped with different levels of difficulty and have a thickness of less than 1 mm, can be rolled. According to the invention, strip speeds of 15 m/sec should not be exceeded at the outlet of the last roll stand regardless of the material being used, and the hot-rolled strip should have austenitic structures. To this end, the invention provides that thin slab thicknesses of approximately 50 mm are used for easily shapeable material, that the first of seven stands is driven or executes only a smoothing pass, the slab is de-scaled in front of and behind the first stand, and that the second to seventh stand effects the reduction in thickness to less than 1 mm.

Hot rolling installation

The invention relates to a method for producing metal strips and sheets involving the following method steps: pouring a strand, which is provided in the form () of thin slabs and which is comprised of carbon steel or special steel, into a casting machine () and rolling the cast product away from the casting heat. The aim of the invention is to utilize free capacities of existing installations, that is, installations not operating at full capacity, with which primary carbon steels are produced, in order to supplement other types of steel or to supplement cast products produced in another manner. To this end, the invention provides that, together with these first cast products (), at least second cast products (), which are produced in a second process route (II) from special steel if the first thin slabs are cast from carbon steel or are produced from carbon steel if the first thin slabs are cast from special steel, are rolled within a joint rolling program.
