Physical modelling of edge rolling in plate mill with plasticine

Abstract

In the plate mill edge rolling is often used to increase yields by reducing defective end shapes. In this study, the effect of process variables in edge rolling on the plane view pattern of the plate was examined by a physical modelling technique with plasticine model material. The prime consideration was given to obtain information on the shape defects of plate such as overlap, width shortage, crop length, bUlging and buckling with respect to process variables which is difficult to check in detail on the shop floor. The result provided valuable information on optimal edge rolling process in spite of some limitation in physical similarity between plasticine and hot steel. Modellversuche mit Plastilin zum Stauchwalzen in GrobblechstraBen. Das Stauchwalzen in GrobblechstraBen sorgt fOr qualitativ besseres Vorband und tragt so zur Erh5hung des Ausbringens bel, In dieser Arbeit wurde die Wirkung der ProzeBparameter beim Stauchwalzen Ober den gesamten Blechquerschnitt untersucht. Die Modellversuche mit Plastilin als Versuchswerkstoff sollten AufschluB Ober Formfehler mit Hinblick auf die ProzeBparameter geben. Es ist sehr schwer, solche Zusarnrnenhanqe in Betriebsversuchen ausfOhrlich zu OberprOfen. Das Ergebnis Iiefert wertvolle Hinweise fOr eine Optimierung des Stauchwalzprozesses, trotz einiger Grenzen, die durch die physikalische Ahnlichkeit von Plastilin und Stahl bedingt sind.

Differential Analysis and Prediction of Planar Shape at the Head and Tail Ends of Medium-Thickness Plate Rolling

“…Scholars worldwide have conducted extensive research on predicting the planar shape of rolled products during the rolling process, leading to significant achievements [8]. For example, a planar shape prediction model has been developed using regression algorithms that determine the functional relationship between rolling parameters and the planar shape of rolled products based on a large volume of experimental data [9][10][11]. Additionally, recent advances in artificial intelligence technology have enabled the use of intelligent techniques in rolling technology development.…”

Study on plastic deformation in cone-type rotary piercing process using model piercing mill for modeling clay

“…They proposed a method to decrease the magnitude of shape defects of plate such as fishtail and overlap, which are generated at the end of the plate. Moon et al (1993) performed an experiment on edge rolling of plate using modeling clay (Plasticine). They proposed a method to decrease the magnitude of shape defects of plate such as overlap and bulging, which are generated at the side of the plate.…”

Development of an Approximation Model of Selected Properties of Model Materials Used for Simulations of Bulk Metal Plastic Forming Processes Using Induction of Decision Trees

“…In turn, it is very rarely that one can come across a study which discusses the tests results of a simulation of processes involving other states of stress. Those infrequent cases include: physical modelling of tube blank rolling [8], longitudinal rolling of metal sheets [24], longitudinal rolling of sections [5] and bending thick metal sheets [21], or helical rolling of tubes [23]. The selection of the modelling material also strongly depends on the simulated phenomenon, while being less dependent on the measurement method.…”
