The invention relates to a method of flying changing of working rolls in continuous casting and rolling installations and hot strip rolling mills, in particular in continuous hot strip rolling mills, wherein for exchange of working rolls by opening a rolling stand, those are disengaged from a to be rolled hot strip. According to the invention a regulated strip tension that can substitute the tension of the open rolling stand, is applied to the to-be-rolled hot strip with at least one hold-down roller that is introduced in a rolling line.

The invention relates to a roller hearth furnace () for heating and/or temperature equilibration of continuous cast products (), comprising a first series of rollers () running in the longitudinal direction () and a second parallel series of rollers () on the outlet side (), wherein a buffer zone () with lifting elements () for the perpendicular transport of the continuous cast product () is arranged between the series of rollers (). Furthermore, alternative arrangements for a further process route () are provided.

A method and a device for producing a metal strip by continuous casting and rolling, in which a thin slab is initially cast into a casting machine, and is subsequently rolled in at least one rolling train using primary heat from the casting cycle. The cast thin slab is passed between the casting machine and the at least one rolling train and at least one holding oven as well as at least one induction oven. The holding oven and the induction oven are activated or deactivated according to a selected mode of operation, that is, a first mode of operation for the continuous production of the metal strip and a second mode of operation for the discontinuous production of the metal strip.

A device for loading the guide surfaces of bearing chocks (LS) supported in the housing windows (SF) of rolling stands with pressure plates (DP) that can be placed on the guide surfaces and that can be loaded by a hydraulic piston (K) supported in the rolling stand housings (ST), wherein devices for measuring the pressure and devices (WM) for measuring the displacement of the piston are assigned to the hydraulic piston (K), and wherein the frictional force is eliminated by adjusting well-defined clearances between the bearing chocks (LS) and the guide surfaces.

The invention concerns a method for producing metal strip () in an installation (), in which a metal strand, especially a thin slab, is brought to a desired temperature and/or is maintained at a desired temperature in a furnace () and is subjected to a rolling process in a rolling train () downstream of the furnace () in the direction of conveyance (R) of the metal strand (). In accordance with the invention, to prevent the formation of scale deposits in the downstream region of the furnace, provision is made for the metal strand () to be subjected to at least one descaling operation during its residence time in the region () of the furnace (). In addition, the invention concerns an installation for producing metal strip.
