Two thin-slab casters supplied to Chinese steelmaker TISCO in 2012 have been upgraded by Italian plant builder Danieli.
Tangshan-based TISCO ordered Danieli Rotelec mould electromagnetic brake technology (MM-EMB®) to produce defect-free thin slabs at high speeds and throughput, said Danieli.
Danieli claims that its Rotelec technology not only produces a global braking function, but also addresses the specific flow problems of thin-slab casters. It uses five electromagnets to produce a static permanent magnetic field across the mould, to generate stabilising and damping functions, in addition to standard braking.
In Q1 2019 the first heat with the MM-EMB® was carried out and only five days later a casting speed of 6.0 m/min on a MC steel grade was achieved, with excellent hot-rolled coil quality results, according to Danieli.
