The invention discloses a strip steel warped head inhibition method, and relates to the technical field of metallurgy device control. The method comprises the following steps of before receiving steelbiting signals of units, controlling anti-stripping water feeding devices below inlets of the units to be independently started; and after receiving the steel biting signals of the units, controllingthe anti-stripping water feeding devices arranged below and above the inlets of the units corresponding to the steel biting signals, to be simultaneously started. According to the method, the temperature difference can be formed between the upper surface and the lower surface of a strip steel head in the threading process, so that the downward bending tension of a certain size can be generated, and the strip steel warped head can be inhibited; and meanwhile, according to the method, the anti-stripping water feeding devices arranged below and above the inlets of the corresponding units are immediately controlled to be
