The signing of a contract in May 2005 for a second annealing and pickling line for hot-rolled stainless steel coils took the collaboration between TISCO and DMS to new heights.
“After the successful installation of a 800,000 t/year annealing and pickling line – then considered to be the largest in the world – which was started up in early 2005, 2 months ahead of the initial schedule, TISCO renewed its confidence in DMS in 2005 with a massive challenge: the installation and commissioning of a stainless steel treatment line with a capacity of 1,150,000 t/year within 21 months. For this unprecedented contract, DMS is leading an international consortium that includes CHUGAI-RO for the furnace, SUNDWIG for the rolling mill at the entry of the production line, SIEMENS for the electrical engineering and UVK for the pickling and degreasing.
Dubbed the "Jumbo Line", this line can boast a number of world-beating superlatives: in addition to providing the largest capacity in the world, it will also offer the largest strip cross section with a thickness of 14 mm and a width of 2,100 mm, and it will be able to process products between 1.4 and 14 mm thick.
The unusually large engineering and equipment studies (involving 3,800 tonnes of DMS equipment) took more than 50,000 hours to complete and mobilised more than 50 personnel during the busiest period.
This line will be the only one in the world with a process section on 6 superimposed levels, 4 of which will be framed and supported by an enormous framework weighing 3,500 tonnes, with the annealing furnace located 20 m above ground, 2 accumulators and the pickling unit. 2 other accumulators will be located below ground, up to 10 metres deep.
In terms of lead times, Fives DMS faces a real challenge. It must design all the equipment for this line within lead times normally associated with a routine contract while integrating the equipment supplied by partners and subcontractors. It will also have a vital part to play in supervising the local manufacture and, then, in conjunction with its partners, in supervising and coordinating the facility’s installation and commissioning in compliance with the customer’s objectives.
Many customers trusted Fives DMS as industrial partner such as :
