DIAGNOSTIC PROPERTIES OF THE DYNAMICS OF THE INTERACTION OF ADJACENT ROLLING STANDS THROUGH A STRIP
Abstract. Dynamic processes are considered – the moment of elastic forces in the roll drive lines and the vibration of the equipment in the mode of interaction of two stands during strip capture and joint rolling. The features of parameter fluctuations are determined when a thick strip is being rolled in the previous stand and at this time it is being captured in the next stand. Due to the presence of wear and gaps, the reaction of the drive line sections is delayed: the larger they are, the longer the delay time. Experiments on operating mills have proven that this time is a fairly important diagnostic indicator. It is proposed to use this feature in six-stand groups of continuous rolling. It is proven that a similar indicator is the speed of shock wave propagation along the drive line from the stand to the engine. A comparison of the delay time and speed during strip capture and stand interaction through the strip is carried out. The methods are implemented by placing vibration sensors on the corresponding sections of the drive line.
Keywords: rolling stand, diagnostics, vibration, technical condition, gaps, delay time, drive line, work rolls, equipment, continuous rolling.
