To investigate the characteristics of the middle-section production equipment for 200 L steel drums and the importance of the pre-rolling technology. According to the constitution and function of the middle-section production equipment, two main production modes including dispersed procedures and centralized procedures were studied, and the 3 typical technological processes for middle-section production were comparatively analyzed. Modern middle-section technological process should be chosen for the middle-section production of professional or bulk production of steel drums, which was barrel body flanging + beading + corrugation→top and bottom pre-rolling→curling. Whereas traditional middle-section technological process should be chosen for the middle-section production of supporting production or small-scale production of steel drums, which was barrel body flanging→beading→corrugation→top and bottom pre-rolling→curling. Middle-section production played an important role in ensuring the processing quality and elevating production efficiency, and the centralization or dispersion extent of the procedures should be determined by the factors such as energy production or supporting and production site.
