The invention provides a method for eliminating peeling of IF steel edge in a hot continuous rolling process, belonging to the technical field of steel rolling. The technical process comprises the following steps: detecting the phase change temperature of IF steel in the hot rolling process by adopting a physical simulation method; properly increasing the temperature of a tapping side of the furnace by a heating furnace by adopting micro positive pressure control to ensure that the transverse temperature difference of a plate blank is controlled to be not higher than 20 DEG C; regulating time sequence of rolling and descaling to avoid temperature of the strip edge from falling into a coexistence region; using an upstream spray pattern to replace side jet for cleaning descaling water of rough rolling and fine rolling to prevent the strip edge from water washing; and taking the temperature of the fine rolling inlet as a control target, which is controlled to be between 1,030 and 1,060 DEG C. The invention has the advantages of simple method and high efficiency. By using the method, the defect of edge peeling of the IF steel can be easily solved under a condition of not influencing the production situation and the performance of the IF steel.
