The invention provides a large rolling mill housing fixed-point rotating tool and a using method, and belongs to the technical field of metallurgical equipment installation. The tool comprises a bottom plate, a rotating disc, a bearing assembly, a fixing ring and balls. The bottom plate is arranged below the rotating disc; the bearing assembly comprises a positioning rotating shaft and a positioning ring; the positioning rotating shaft is arranged on the lower surface of the rotating disc; the positioning ring is arranged on the upper surface of the bottom plate and is rotationally connected with the positioning rotating shaft; the fixing rings are arranged on the outer side of the positioning ring at intervals, and balls are movably arranged between the fixing rings. The tool is installed below the rolling mill housing to drive the rolling mill housing to rotate, so that the main rolling span transverse center line of the rotated rolling mill housing is collinear with the main rolling span transverse center line of the installed rolling mill housing in design. Precise rotation of the large rolling mill housing is achieved, overall operation is scientific, reasonable, safe, reliable, efficient and fast, the construction period is shortened, the cost is reduced, and favorable conditions are created for further transportation and installation of the large rolling mill housing.
