Based on industrial research of continuous wide-stand hot rolling mills, several methods have been developed to determine the technical condition, primarily the value of the angular gaps in the drive line of the rolls of the rolling stands. The methods use measurement data during the transitional period of the rolling stands operation, during the capture of the stand by the rolling rolls. The first method is based on measuring the propagation velocity of the elastic deformation wave along the elements of the drive line, the second uses the technological features of simultaneous rolling in two stands, the third - the relative reduction of the period of oscillations of the transient process of the electromagnetic torque of the engine.
