Owing to the installation of vertical pentagonal rollers in curved track sections and installation of steel rope clampers to the mining cars,the traction steel ropes are brought into restriction and the mining cars can travel along the curved tracks.

The rolling effects of horizontal and edger rolls were both taken into account during load distribution,and iterative computations were done alternately along the width and thickness of work piece by virtue of the equal load function to optimize the rolling schedule step by step.

A series of flexible U sections,changed in its sections,was separately simulated and analyzed by edger roll forming and flat roll forming.

Research and experiment with changeable universal roll method for the axes of vertical rollers of H beam mill;

The peeling on vertical rollers of second stand quenched by high frequency equipment was observed during service due to stress concentration.

The vertical rolling process with groove in various temperature difference were simulated and the mathematical model of "dog bone" shape were obtained.

The influences of vertical roll installation place to product's size and the infeuences of vertical roll adjustment angle to product's surface have been discussed in this paper.

This article analyzed the source and formation of the resistance of forming vertical roll in welded pipe mills.

This paper states the significance of the application of CAD technology to roll flower in cold roll forming.
