Preliminary Design and Assessment of a Novel Electromagnetic Edge Dam for Aluminium Twin Roll Casting

Abstract:

Past work has shown non-contact, electromagnetic (EM) edge dams to be feasible alternatives to conventional refractory mechanical edge dams for containing liquid metal in twin roll casting, particularly in aluminium. However, these EM edge dams have had limited application. A novel EM edge dam geometry is proposed, applicable to a range of horizontal twin roll caster designs without significant modifications to the main caster structure. The design is analysed using finite element modelling. Static experiments using Wood’s metal are used to verify the performance of the proposed novel EM edge dam. The novel edge dam is compared with others in the literature, with particular attention to strength and stiffness constraints that determine the operating window.
