According to the blast furnace air supply middle section replacement equipment and method, an existing forklift is improved, a hydraulic control system and an air supply middle section branch pipe dismounting and mounting device rapidly connected with the forklift are arranged on the forklift, and a multi-way hydraulic control valve and a multi-way manual hydraulic reversing valve are connected through a plurality of hydraulic pipelines; according to the blast furnace air supply middle section branch pipe replacing equipment, the upper flange of the blast furnace air supply middle section branch pipe is connected with the hydraulic cylinders, and then the lower flange of the blast furnace air supply middle section branch pipe is pressed through the flange pressing claws connected with the hydraulic cylinders, so that the blast furnace air supply middle section branch pipe is rapidly disassembled, assembled and carried away. And the blast furnace air supply middle section branch pipe can be quickly disassembled and assembled, so that the maintenance time is greatly shortened, and the maintenance efficiency is improved. The device is a most convenient and effective tool for realizing quick replacement of the middle air supply section of the blast furnace, has good practicability and feasibility, and has a good prospect of wide application.
