Earlier this week, the vessel shell for the new hot-blast stove #47 for blast furnace #4 at SSAB Oxelösund, Sweden, was erected. The entire vessel shell was fully prefabricated in an off-site workshop and erected in its operating position in a single lift.
This was the first time that such a manufacturing solution was applied to a blast stove.
The erection was smooth thanks careful planning and consideration with SSAB about ground and underground infrastructure in the blast furnace area.
This effort pays off substantially: the execution of all the welding, coating and inspections in the off-site workshop minimizes on-site work and under more difficult circumstances and plant regulations, saving a considerable number of work hours.
This strategy applied by Danieli Corus brings about major efficiencies in terms of supervision, scaffolding and logistics.
The installation of hot blast stove #47 now will be completed at maximum efficiency.
As part of the a large scale technical overhaul project for the Blast Furnace No. 2 and 3 at their Ural Steel plant in Novotroitsk, Russian steel producer Metalloinvest has selected Danieli technology for an upgrade to the top charging system of Blast Furnace No. 3.
The results of the Danieli Automation Q-One power system installed at ABS Sisak meltshop for special steel (Croatia), confirmed an impressive increase of active power availability and EAF efficiency.
Ternium chose Danieli to supply an inventory management system and fully automatic handling equipment that will feed 4.1 Mtpy of slabs to a greenfield hot-strip mill at Pesqueria, Mexico.
Wälzholz relied on Danieli to expand production of high-performance steel strip.
The brand new, 14-m five-strand bloom caster was started successfully after less than 13 months from the contract signature. A joint effort of Valin and Danieli site teams made possible machine erection in just 38 days, limiting the cold tests to just 11 days.
Danieli Olivotto Ferrè successfully started up a Tube Roller Hearth Annealing furnace at Tenaris Tamsa, in Veracruz, part of one of the world’s largest manufacturers of steel pipe for the energy and automotive industries.
