T-bar Universal Rolling and Its Deformation Properties

摘要

A new method of rolling T-bars using a common universal mill for H-beams was investigated. To study its deformation properties, model rolling experiments and finite element analyses were carried out. Before the experiment, there was concern about large side camber of the rolled T-bars due to the asymmetric section shape in universal rolling. However, it was shown that the side camber could be controlled by adjusting the balance of the web and flange thickness reductions. The spreading behavior of the flange and web were then studied in detail by experiments and numerical simulations. Linear relationships between reduction balance and spread parameters were found, enabling the spread deformation to be predicted by using model equations. Moreover, the similarity of the flange spread behavior between T-bar and H-beam universal rolling was investigated by numerical analysis. The result of this research suggested the high potential of this rolling method for flexible T-bar production.
