<p>GOK 103-071 A rolling mill section for rolling or roughing slab, plate, billet or structural section is provided with a load sensing arrangement for determining if the extent of non-synchronization between the respective drive motors of the rougher stand and the edger stand is sufficient to cause significant tensile or comprehensive loading in the member being rolled, at it passes between the two stands. The existence of such loading is determined by providing a coupling or utilizing existing mechanical connection of the one or both structures of the stands, and measuring reactive forces generated thereat by the passage of the member being rolled, tending to displace one stand relative to the other. A readout from the force measuring means is used to control the relative torques of the respective stand motors so as to promote synchronicity of the two drives, in order to reduce damaging overloads in the edger or in the rougher which otherwise result when significant lack of synchronicity is present.</p> |
