When both the EM and EPR technologies can be used for an application, the recommendation for one technology versus the other depends on the possible limitation of material temperature and on the safety level requirement of the application. Moving slabs in a slab yard is not as critical, from a safety point of view, as loading or unloading slabs into or from a vessels in a port. EPR technology is particularly suitable for remote operation because force is constant and duty cycle is not an issue.
For hot applications and intensive duty cycle ones, typically at the exit of a caster , SGM disposes of a proprietary magnet called Convection Electro Lifting Magnet which, thanks to its special design for heat dissipation, drastically extends its duty cycle and life time.
