Abstract (en)
[origin: EP0000454A1] 1. A method of monitoring the interstand tension exerted on thick products which are hot-rolled, engaged between two successive stands comprising working rolls, characterised in that - the speed of passage Vs of the product between the stands is measured continuously, - the linear speed Vc of the surface of the working rolls of one stand is measured continuously, - the slip value go for this stand is calculated from the previous measurements, - the speed of rotation of the working rolls of at least one of the two stands is acted upon so as to maintain the slip value close to a reference value corresponding to a state of weak traction.
