The crystallographic texture of Ti–29Nb–9Ta–10Zr alloy is studied after cold-rolling with different amounts of thickness reduction, up to 60%. The major texture components developed during cold-rolling were: γ-fibre components: {111}〈 〉, {111}〈 〉, {111}〈 〉 and {111}〈 〉; texture component: {112}〈 〉 and texture components: {001}〈 〉 and {010}〈001〉. Besides crystallographic texture the resulted mec...

the objectives in the cold rolling process include improved sheet surface quality, enhanced steel mechanical strength, and better solidification operations. given the increasing demand for higher steel surface quality, more rapid production, and thinner steel plates, more attention has been directed toward the parameter of temperature in cold rolling as a means of achieving the above objectives...

Strip profile control in cold rolling of thin strip is a difficult and challenge problem found in industry. Currently using the novel type of strip rolling mill, such as the work roll crossing and shifting is the one of the main methods to control the strip profile quality in cold rolling. In this paper, 3-D finite element simulation models of the thin strip profile in cold rolling for the work...

The tandem cold rolling process is continuous production, and it desired to achieve a stable operation process, the incoming materials need be welded in length direction before rolling. Usually head tail of material have thickness dimension positive deviation, there are two alignments front rear strip, so that different weld zone profiles can formed. In this research, we built an FEA (finite el...

It has recently been shown that Severe Plastic Deformation (SPD) techniques could be used to obtain nanostructured metal hydrides with enhanced hydrogen sorption properties. In this paper we review the different SPD techniques used on metal hydrides and present some specific cases of the effect of cold rolling on the hydrogen storage properties and crystal structure of various types of metal hy...

In cold rolling of silicon steel strip, edge drop directly affects the side cutting and yield steel. To improve in process, a multi-stand coordinated control strategy model based on multi-objective optimization are proposed. The first step is to analyze influence each stand work roll shifting (WRS) through finite element (FEM), then determine effectiveness actuator. Meanwhile, fitting proposed ...
