Hot start-up of Danieli mould electro-magnetic braking for Tangshan thin-slab casters

After seven years of operation Danieli carried out upgrades to the two thin-slab casters supplied in 2012 at TISCO in Tangshan, China.

TISCO ordered Danieli Rotelec mould electromagnetic brake technology (MM-EMB®) to produce defect-free thin slabs at high speeds and throughput. This technology not only produces a global braking function but also can flexibly address the specific flow problems of thin-slab casters. It uses five electromagnets to produce a static permanent magnetic field across the mould, to generate stabilizing and damping functions, in addition to standard braking.

In the first quarter of this year 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.
