Abstract

Manufacturing steel complex figurine parts remains a fundamental scientific challenge. This article suggests the solution of using hybrid methods that unite processes like combined rolling/stamping, rolling/plastic bending, and asymmetric rolling to produce steel complex figurine parts with wall thickness of 40-100 mm and diameter (width) up to 4000 mm. Traditionally, machine-building factories produce large-size bodies of rotations, with the help of an inefficient and rather costly process, using stamping or sheet-bending machines. These details are designed for usage as casings for various technological aggregates (converters, mixers, scrubbers, steel teeming ladles, etc.). The aim of the work is to develop a technology for obtaining large-sized parts with a curved surface in conditions of a plate rolling mill. The man objectives of the study:1) The choice and adaptation of the visco-plastic mathematical model for describing the new combined rolling and stamping and asymmetric rolling and plastic bending processes of production large-sized parts with a curved surface; 2) Numerical and experimental studies of the new combined processes with the study of the influence of various parameters on the geometry and mechanical properties of large-sized parts with a given curvature; 3) Determination rational process schemes and operating modes of the combined processes of production. large-sized parts with a curved surface. The chief features of new hybrid processes are identified. Results of theoretic and experimental investigations are provided. A technology of manufacture of converter housing parts at the 4500 PJSC "MMK" has been developed. Two cases were manufactured and installed in PJSC MMK. The economic effect was more than 1 million dollars.
