In order to solve the problem of wide magnesium strip uneven deformation in electroplastic rolling, an field measurement device was designed. The simulates actual electro-thermal characteristics and provides as even constant conditions possible for high-efficiency Mg rolling. Firstly, effect electrode position distance on electric unevenness is observed by setting rolling condition, provide opt...

Flatness measurement using shape-rolls has been used in cold rolling mills for a long time. The benefit is obvious since the measured flatness profile can be used directly to control roll bending, tilt and cooling profile. It was therefore integrated in the mill control system at an early stage to control the strip shape against a target I-unit profile. However, since the flatness is also affec...

During last two decades great attention was paid to materials with grains of diameter smaller than 1 μm. These materials were classified as Ultra Fine Grain (UFG) materials with diameter of grains of the order of 100 to 1000 nm and nano-materials with mean diameters of grains smaller than 50 nm. This research concerned the whole production of UFG materials, using Severe Plastic Deformation (SPD...
