Phenomenological approach to the description of deformation resistance behaviour of steel and its microstructure development under the service hot rolling condition is still the most common useful and powerful. Utilising different experimental equipment such as torsion plastometer [1-5], compression plastometer [6-9], or advanced laboratory mills [10, 11] as well as different deformation techni...

This research introduces an advanced forging method to produce the door frame of the wind turbine tower. The advantage of the new forging method is the increase of raw material utilization ratio and the energy saving. In the conventional method, the door frame is hot forged with a hydraulic press and machined out lots of material because of the big difference between forging shape and final mac...

This paper is concerned with investigations into the effect of tension between the stands of the finishing mill on width control in a hot rolling process. An analysis is given to predict satisfactorily the variation in width due to spreading and also due to strip tension between the stands. Wusatowski's model which is developed to give an account of spreading is specified and a similar model to...

Temperature is the main process variable needed for every operation in hot rolling process for all value addition activity and can be considered as main variable also to control pollution.. It is a tool for the steel hot rolling plant to improve profitability, environment and productivity by controlling the process energy balance by its sequences optimization. In the steel rolling plant the imp...

in this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % si non-orientedelectrical steel was investigated. for this purpose, all samples were processed through single-stage hot rolling at1100 ° c and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °cfor 35 seconds. finally, all of them were fully...

By using some finite local rings, we construct some new partial difference sets and relative difference sets on ^-groups where p is any prime. When p = 2, some of the partial difference sets constructed are reversible difference sets which include Dillon's difference sets.
