The invention discloses a slab position tracking and correcting method for a hot-rolled slab sizing machine, and belongs to the field of control. Respectively establishing corresponding tracking points in the SSP areas; a group of tracking detectors are arranged at each tracking point, and when any tracking detector detects the head or the tail of the plate blank, the position of the plate blank in the PLC is corrected into the position of the corresponding tracking sensor in real time; when the plate blank is in a rolling state and an L1 tracking system selects an integral speed, adopting a speed following logic, so that the speed of a roller way near a rolling mill is synchronous with the speed of the rolling mill, and meanwhile, the influence of forward sliding and backward sliding of the plate blank is also considered; in the SSP area, the position of the plate blank located in the SSP area is tracked and positioned by calculating the speed and the lateral pressure amount of an inlet pinch roll and an out
