Abstract: The invention discloses a self-adaptive hanging structure of a converter, including vertical connecting rod mechanisms connecting the lower edge of a backing ring body and a lower half converter body of the converter, and horizontal connecting rod mechanisms connecting the upper edge of the backing ring body and an upper half converter body of the converter; the horizontal connecting rod mechanisms are located above the vertical connecting rod mechanisms, the plane where the axis of a trunnion on the backing ring body and the axis of the backing ring body are located serves as the first reference plane, the symmetric center of each vertical connecting rod mechanisms is located in the radiation area of the first included angle, the two planes forming the first included angle coincide with the axis of the backing ring body, and the included angles being 15 degrees and 50 degrees are formed between the two planes and the first reference plane respectively.
