The invention discloses a method for improving the wedge shape of hot continuous rolling strip steel. The method for improving the wedge shape of the hot continuous rolling strip steel involves a horizontal rolling mill, a vertical roll, a vertical roll gap adjusting device and a multifunctional thickness gauge, wherein the multifunctional thickness gauge is used for detecting an actual wedge-shaped value of a rolled piece at an outlet of the horizontal rolling mill, and then converting the obtained actual wedge-shaped value into vertical roll center line offset, the vertical roll gap adjusting device is used for receiving a given vertical roll center line offset, converting the given vertical roll center line offset into a corresponding AWC hydraulic cylinder extension amount, and increasing the corresponding AWC hydraulic cylinder extension amount to an original AWC hydraulic cylinder extension amount; and the vertical roller is used for enabling the next rolled piece to enter the horizontal rolling mill to
