The invention discloses a hot rolled strip steel coiler side guide deviation correction control method. The method includes the steps of opening two side guide plates to a preset width Wo before strip steel is out of a rolling mill and setting the two side guide plates to be under the pressure of zero when the head of the strip steel is detected to be out of a finishing mill; performing a first short stroke closing on the side guide plates to enable the spacing of the two side guide plates to be Wo1 when the head of the strip steel enters a position between the two side guide plates and performing a second short stroke closing on the side guide plates to enable the spacing of the two side guide plates to be Wo2 when the head of the strip steel is out of the position between the two side guide plates; accumulating pressure values of the two side guide plates respectively from the start of loading of a pinch roll of a coiler to the end of the loading of the pinch roll of the coiler, selecting a position control side A and a pressure control side B, performing pressure control, and repeatedly performing edge seeking transition until the end of the edge seeking. The hot rolled strip steel coiler side guide deviation correction control method enables the position control side A to be constant in pressure value by adjusting the pressure of the pressure control side B, greatly reduces the abrasion of strip steel edges and the side guide plates to prevent the strip steel edges from folding and scratching under the condition of ensuring the alignment of the strip steel edges and has practical and popularization values.
