The invention relates to rolling mill mounting. A rotary hoisting method of a bracket of a large rolling mill stand comprises hoisting carrying pole beams of two cranes, wherein each carrying pole beam is connected with the rolling mill stand by utilization of a steel wire rope and a hanging tool; the rolling mill stand is placed on a temporary supporting structure before hoisting, rotates around the temporary supporting structure by using the bracket of the rolling mill stand till the rolling mill stand rotates and stands upright during hoisting and is placed in a mounting position of a rolling mill base; the temporary supporting structure is mainly erected by billets, a steel tube, wood beams and structural steel, a vertical billet is placed on a roll exchanging rail base, longitudinal billets are structured by laminating and paving a plurality of billets on the vertical billet and a side face base of a roll exchanging pit, the wood beams are placed on the longitudinal billets, and baffle plates are arranged around the wood beams; two ends of a transverse billet are placed on the vertical billet, the supporting steel tube is welded in the middle part, and a sleeper is placed on the transverse billet. The rotary hoisting method provided by the invention greatly reduces the requirement on the hoisting height of the cranes during hoisting and overcomes the deficiency of conventional two-crane hoisting method, so that the construction cost is lowered.
