Metallurgy and heavy engineering construction, which are considered the most energy-intensive industries, place great focus on complex shaped thick-gage plate metal items of equipment with the wall thickness exceeding 40 mm and the diameter/width of up to 5000 mm. Such items of equipment include large machine parts manufactured by means of hot plate stamping, like bodies of rotation (for example, the segment of the radial surface of converter shell, the bottom part of degassing unit, etc.) utilized as pressure-operated devices, vessels, tanks and other facilities by metallurgical, petrochemical, oil and gas, and nuclear industries. Presently known manufacturing methods of such items of equipment, for example hot stamping methods, have a number of technological problems. The proposed work is aimed at the development of innovative power-efficient, high performance methods of obtaining complex shaped large size items. The scientific novelty of the task lies within the creation and development of the theory and technology of the new methods of deformation based on the combination of the plate rolling and stamping processes as well as the combination of asymmetric rolling and plastic bending processes. Casings on two converters were produced and installed in the oxygen-converter plant. Economic effect from the installation of the developed technology based only on the combination of asymmetric rolling and plastic bending processes was more than 1 million dollars.
