Theoretical and Experimental Study of the Tandem Skew Rolling Process

steel research international, 2018
The deformation characteristics and the roll force are of significant importance in the rolling of seamless steel tubes with a tandem skew rolling (TSR) process. In this paper, finite element methods and dual stream functions are utilized to analyze tube rolling with the TSR process.

Automatic video deshearing for skew sequences capturedby rolling shutter cameras

2011 18th IEEE International Conference on Image Processing, 2011
A novel automatic video deshearing is proposed to reduce the skew artifacts (jelly artifacts) in sequences captured by CMOS censor cameras. The paper first considers the principles of skew artifacts in rolling shutter cameras. Then a deshearing algorithm with high accuracy is discussed with automatic skew artifact detection.

The Use of Skewed Rolls in Calendering Operations

Journal of Applied Mechanics, 1950
Abstract In many commercial operations it is desirable to produce a uniform sheet of material by passing the viscous raw ingredients through rotating cylindrical rolls. With rolls supported at the ends only there is danger of wide variations in thickness of the finished product.

Influence of Surface Roughness Skewness on Rolling Contact Fatigue Life

Tribology Transactions, 1992
Rolling element bearings operating under mixed or boundary lubrication conditions experience a higher metallic contact ratio (MCR) between the surfaces, and a corresponding decrease in rolling contact fatigue life. This paper evaluates the effects of randomly distributed small indentations, or pits, on the lubricating properties when operating under ...

The Analysis of the Stress and Strain in Skew Rolling

Advanced Materials Research, 2012
In this paper, three-dimensional finite-element model for the skew rolling (helical-groove rolling) process has been used to characterize the workpiece material stress,strain and deformation behavior. Particular attention has been paid to representative cross section and the center, edge and mid-radius points of the ...

Processing Non-oriented Electrical Steels Using Inclined/Skew Rolling Schemes

2017
Obtaining the ideal {001}⊥ND texture in non-oriented electrical steel sheets was the goal of many past investigations. However, it was difficult to achieve the desired texture using conventional rolling techniques since the metallurgical mechanisms governing the thermomechanical processing usually promote the formation of the undesired {111}⊥ND texture.
