Реферат | The multiple-purpose way of radial-shift rolling (RSR) and various mini-mill structures of new generation are described. Helicoidal metal outfl ow 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. Here, deep compaction and metal structure development throughout all the levels of the metal-physical morphology take place. Concerning the morphological structure, the metal after RSR becomes a material of new quality. Complex improvement and stabilization of physicalmechanical and service metal properties are reached at the level essentially exceeding the traditional one. The greatest increase is occurred 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 is presented. Among them: deep metal structuring and improvement of its pro perties 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 diameter for piercing with improvement of the continuously-cast product structure and toughness. |
