Baotou Steel Group Co. Ltd. in China selected Danieli to modernize its 600,000-tpy wirerod mill. The key equipment to be supplied will be a new, four-pass TMB high-speed finishing block to produce smooth-wire from 4.5 to 26 mm diameter, and rebar-wire from 6 to 16 mm diameter at a maximum speed of 110 mps.
The first two passes of the TMB will allow high-reduction ratios in order to perform low-temperature rolling (LTR), to achieve finer grain size and better mechanical properties in the final products.
The new equipment will make it possible to achieve strict product tolerances and to increase the range of sizes produced. The shorter changing time will bring higher material yield and higher production flexibility.
The line start-up is is scheduled for the beginning of 2020.
Tokyo Steel, the largest steel scrap consumer in Japan, purchases various types of scrap to feed its electric-arc furnace melting process.
Gerdau contracted Danieli to upgrade its rolling mill #3 in Pindamonhangaba, São Paulo, in order to be able to produce spring steel flat bars. The mill, producing specialty steel round bars, has recently been supplied by Danieli.
Danieli has been awarded a contract by PAO Severstal for the upgrade of plate mill 2800 at Cherepovets (Russia), in order to improve plate surface quality and increase production volume.
Recently Danieli Breda performed the Final Acceptance Tests (FAC) on the new graphite extrusion technology supplied to Graftech Ibérica SL, Navarre, Spain, for the production of the graphite electrodes.
Acerinox, a global stainless steel manufacturing group, contracted Danieli Automation for the electrical and automation revamp of the stainless steel slab caster at Columbus Stainless (Pty) Ltd., Mpumalanga, South Africa.
Tung Ho Steel Vietnam again chose Danieli to upgrade its 600,000-tpy flexible rolling mill in Phu My. Coming four months after the FAC for the new bar and light-section rolling mill, this order consists of an in-line water quenching system for 10- to 43-mm straight rebars.
