Turbulent snow transport and accumulation: New reduced‐order models and diagnostics
Quarterly Journal of the Royal Meteorological Society, EarlyView.Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

Virtual rolling quality system for cold rolling
Steel Research International, 2010A prototype of virtual rolling quality system for a 4 stands cold rolling process is created. In this system virtual sensors and models are used to calculate quality features based on process information and analyzed history data. The virtual-sensor technology is developed for estimating of hard-to-measure variables and further on to define methods to ...

Roll Camber Design for Cold Rolling Mills
IFAC Proceedings Volumes, 1976Abstract The advent of automated, high-speed tandem coldrolling mills for wide strip has reduced the available manpower for observing and controlling strip shape (or flatness) after each stand. Consequently there has been an increased emphasis on selecting ground roll cambers which minimise manual adjustments of coolant flowrate and roll bending ...

A theory of cold rolling of thin gauge strip is presented which, within the idealizations of homogeneous deformation and a constant coefficient of Coulomb friction, rigorously models the elastic deformation of the rolls and the frictional traction at the interface.

The morphology of unidirectional cold rolled polyethylene was investigated. The techniques of scanning electronmicroscopy, wide angle X-ray diffraction, DTA, and XYZ photographic light scattering were employed. Most of the study was undertaken using low density polyethylene which had been initially cold rolled to an elongation of 100% and then annealed

Simulation of a Cold Roll-mill
IFAC Proceedings Volumes, 1987Abstract The paper describes the complete digital simulation of a four-stands continuous cold strip mill with its sheet supply and coiler. The whole program contains 150 integrators and twenty circular tables for variable delays. All models are non-linear and the programmation is implemented in ACSL language.

The invention relates to a cold rolling method for metal stock (4). The metal stock that is to be rolled (4) passes through a roll gap (3) between rollers (2) which are driven in an opposite direction at room temperature for plastic deformation. In order to avoid problems caused by the use of liquid cooling lubricants and to create an improved surface ...

AbstractAn interactive graphic simulator of the cold rolling process has been developed. The rolling pressure model is based upon the Bland–Ford theory and includes the elastic deformations of strip and work rolls. The transverse elastic deformation of the four-high roll system is modelled by a polynomial parametrization of the results from a finite ...
