AbstractThis article describes the operation of four-roll passes for rolling of nonsymmetrical flange channel sections. Transformation reasonability of existing two-high mill stands into universal ones is exemplified by channel section rolling at linear rolling mill. Technology and equipment are developed for fabrication of channel sections using f...

The results of experimental and theoretical studies on the technology of rolling tramrails in continuous reversing tandem train of stands of a universal rail and structural steel rolling mill are presented. Best-performance speed charts for the main drives of the rolling stands are drawn. A new approach to high-speed rolling schedules for rolling g...

This article concerns the development of an energy-efficient technology for rolling one of the most complex (from the standpoint of plastic strain) rail profiles – the grooved tramrail. A new technology which makes efficient use of the roll forces in the horizon plane is proposed. This technology makes it possible to obtain a balanced four-roll pas...
