Putting into practice innovative potential in the universal radial-shear rolling process

Various mini-mill structures of new generation for imple- mentation of multiple-purpose radial-shift rolling (RSR) are described. Deep compaction and metal structure devel- opment throughout all the levels of the metal-physical mor- phology take place during helicoidal metal outflow along the prescribed trajectories with deceleration of the outer layers of stock material and acceleration of the inner ones creates intensive shift displacements in the deformation zone. As for morphological structure, it is shown that the metal becomes a material of new quality after RSR. Prin- cipal improvement physical and mechanical metal proper- ties are noted on the permanent base. The best results are reached in plastic and viscous performance properties as well as in those, which are correlation-associated with them. A number of highly-effective innovative technics of deformation processing of miscellaneous metals and alloys, such as deep metal structuring and improvement of its prop- erties in elongated volumes by intensive plastic straining; creation of automatic complexes of thermo-mechanical processing; return to the economic circulation (recycling) of out-of-service rods and off-gage bar-profiled residual portions; production of stock materials of optimum diam- eter for piercing with improvement of the continuously-cast product structure and toughness, are presented.
