lead as amodel material to simulate mandrel rollingof

It is demonstrated how the strain rate analysis of the tube deformation during mandrel rolling enables the total generalised strain and the mean yield stress to be determined for further theoretical analysis. This paper discusses the use of lead to simulate the longitudinal rolling of hot steel tube through grooved rolls under laboratory

An Overview of Rolling Machines. Plate or sheet bending rolls are offered in two distinct categories: single and double-pinch, but they may vary in geometry or style. General machine styles are three-roll initial-pinch, three-roll double-pinch, four-roll double pinch, three-roll variable translating, three-roll pyramid, and two-roll systems

Steel - Steel - Tubes: Tubular products are manufactured according to two basic technologies. One is the welding of tubes from strip, and the other is the production of seamless tube from rounds or blooms. The most widely used welding system, the electric-resistance welding (ERW) line, starts with a descaled hot-rolled strip that is first slit into coils of a specific width to fit a desired

This is generally used when pure countercurrent flow is required in a two tube side pass unit. This is achieved by having two shells side passes—the two passes being separated by a longitudinal baffle. The main problem with this type of unit is thermal and hydraulic leakage across this longitudinal baffle unless special precautions are taken
