Abstract: The quality of the grain-oriented silicon steel coil is directly related to the steel's yield. According to the slippage of the coiling tail of the hot-rolled base material of the oriented silicon steel produced by a steel plant, the main reasons for the occurrence were analyzed. With measures such as the adjustment of the lag rate and the adjustment of the center line of the finishing rolling, the tail coil shape of the grain-oriented silicon steel has been greatly improved.

Key words: tail slip, pinch roll gap, side guide, lag rate
