Effect of Grain Size on Cross Wedge Rolling of Micro ...

+

This study investigated the effect of grain size on the cross wedge rolling of micro copper rod. Annealing techniques and equal channel angular extrusion were employed to refine the grains of copper, after which the treated copper was machined to prepare the cylindrical billets with 1 mm diameter for conducting experiments. The billets were rolled between a pair of the dies fixed in a ...

The paper presents the results of numerical modeling of a crosswedge rolling process for producing a stepped shaft. The modeling was performed with commercial software Forge NxT using the finite element method. The numerical analysis enabled the determination of changes in the shape of the workpiece, effective strain, damage function and temperature distributions, as well as variations in ...

The influence of the rolling temperature regimes on formation of hotrolled strips crosssection was investigated. The hotrolled strips were rolled on longitudinal wedge mill. It is proved that the workpiece is deformed in the conditions of "soft" SSS in a mill of new construction, in other words the amount of the elastic deformation and ...

The objective of the control is to maintain a parallelloaded roll gap so that no wedge is formed even under asymmetric rolling conditions. The traditional solution is to level the work rolls of the mill stand according to the measured differential roll force multiplied by a constant differential stand modulus.

At today's demanding condition, maintaining stable operation of rolling mill is becoming difficult. MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the opposite side with constant force. MSD eliminates gap between roll chocks and mill housing, keep rolls in proper position and stabilize rolls.
