The invention belongs to the technical field of correction of the ovality of a large-diameter steel elbow, and discloses a correction method for the ovality of the large-diameter steel elbow, which comprises the following steps of: 1, positioning before ovality deformation detection of the large-diameter steel elbow; step 2, detecting the ovality deformation of the large-diameter steel bent pipe; step 3, verifying the ellipticity deformation detection data of the large-diameter steel elbow; step 4, establishing a rounding algorithm expert database algorithm model; and 5, roundness correction of the ovality of the large-diameter steel bent pipe is carried out. The method has the beneficial effects that 1, the special electronic ruler can be conveniently carried, and the complexity of ovality deformation detection of the large-diameter steel elbow pipe is simplified; and 2, online matching with automatic roundness correction equipment is realized. And 3, by utilizing a rounding algorithm expert database, accord
