Effects of skin pass rolling parameters on mechanical ...
Skin pass rolling was performed on a laboratory mill equipped with a device designed to reproduce the effects of sheet tension and with load cells aimed at measuring the main working parameters. Analysis on tensile properties of skin pass rolled samples showed for an ultralow C grade and a low C grade a decreasing trend of the yield strength down to a minimum, followed by progressive rising ...

How important is sheet and plate steel flatness?
The idea to use temperpass rolling mills in conjunction with leveler, cuttolength lines was not addressed until the late 1980s when Robinson Steel successfully installed its first line. This integration allowed the steel processor not only to remove inherent rolling stresses but also to remove coil set more easily. Today North American fabricators routinely request temperpassed steel. At ...

Taper Tension for Rewind Control: Definitions Processes ...
Taper tension is the process of gradually decreasing web tension as the material is wound at the recoiler so that the larger the diameter of the coil, the lower the tension. How to Use Taper Tension for Rewind Control. The best method of achieving taper tension is to measure the diameter of the roll, either using an ultrasonic sensor or two pulse tachometers (one on measuring revolutions of ...
