The invention relates to a lifting method of rolling mill housings. The method comprises the steps that door-shaped lifting structures composed of towers and a beam are arranged on the two sides of a rolling mill housing installation foundation, and a lifting device is installed on the beam; the lower portions of the rolling mill housings are jacked by a jack, the heads of the rolling mill housings are connected with a lower suspension point of the lifting device through a special rolling mill housing lifting device, and a slippage trolley is placed below the tails of the rolling mill housings; the lifting device is slowly loaded, the slippage trolley is pushed while the heads of the rolling mill housings are lifted so that the tails of the rolling mill housings can be moved till the rolling mill housings are rotated to be in the vertical state; and the rolling mill housings are slowly placed down in the vertical state and are placed in place to be fixed, and the special rolling mill housing lifting device at the heads of the rolling mill housings is disassembled. The stable door-shaped lifting structure composed of the towers and the beam is adopted, the lifting device is used as a main power device, the slippage trolley is used as an auxiliary device, the method that the heads are lifted and the tails slide is adopted for lifting the rolling mill housings, the whole lifting process is stable, rapid and safe, and the lifting efficiency is greatly improved.
