Abstract

Electromagnetic brake (EMBr) technique is adopted to reduce the turbulence of molten alloy in the slab mould in the continuous casting process, especially under high casting speed. We introduce a state-of-the-art EMBr technique by reviewing the published literature. The main objective of this paper is to give a clear view of the EMBr technique in terms of the magnet arrangement, along with their “Braking” effect to help decision-making. The EMBr system can be divided into three types, in terms of the magnet arrangement: the Local type, the Ruler type and the Multi-mode type, respectively. Both advantages and disadvantages of each type have been discussed. Further challenges are also raised.
