Abstract (en)
[origin: US6378346B1] The invention relates to a Steckel hot rolling mill comprising at least one reversing roll stand (1) as well as coilers (6,7) which are positioned upstream and downstream and present torque-controlled drives. The aim of the invention is to improve such a hot rolling mill in such a way that it optimally counteracts variations in tension and/or mass flow caused by changes in process parameters and allows for high quality hot rolling, especially of very thin hot rolled strips. To this end the invention provides for a looper (8,9) to be positioned between both the coilers (6,7) and the reversible roll stand (1), which supplies actual values for adjusting tension and mass flow.
