View of October' 2009 Issue ========================= China’s largest slab casting complex (7-Mtpy) successfully commissioned at Shougang Jingtang I&S United Co. By our news Bureau ABSTRACT In October 2006 Danieli Davy Distington (DDD), signed a major contract with Shougang Jingtang Iron & Steel United Co. (SGJT) for a new slab casting complex, to be installed in the industrial area of Caofeidian, near Tangshan (Hebei Province). The contract covered two new, 2-strand slab casters (Casters No. 1 and No. 2) to produce about 7 Mtpy of slabs. A few months later, SGJT ordered a third two-strand caster to be installed at the same site (Caster No. 3) in order to increase the slab production to over 9 Mtpy, making this site one of the most prominent plants in China and in the world. The “driving force” of this ambitious project is to move the old Shougang (Capital Steel) plant from the Beijing metropolitan area to this completely new industrial site, mainly for environmental reasons. It will become one of the biggest in China and the one with the lowest impact on the environment, even with its massive size. While the upstream blast furnaces and steelmaking shop are under final cold testing, the customer decided to commission the slab casters first, in order to ensure that when the BF starts production all the steel can be successfully transformed into slabs, from the start. On March 14, 2009, the first heat was cast on Caster No. 1, and on April 10, 2009, the first heat was produced on Caster No. 2, both in a fully automated mode. Commissioning of both slab casters progressed smoothly. Danieli personnel actively worked together with SGJT to make the successful run-through, from the converter, ladle furnace and slab caster. Actually, the 300-t heat cast on March 14 was the very first heat of the complete plant, and it used the first steel produced by the converters starting from the pig iron transferred by trucks from the nearby Tangshan steel plant in 60-t ladles. The new SGJT casters feature the renowned DDD INMO mould and Dynamic Soft Reduction and will allow casting speeds up to 2.3 mpm, with a metallurgical length of about 44 m. The roll diagram for all the three casters was developed from high-quality concepts of vertical curved caster (main radius of 9.5 m) and continuous bending and unbending design. Danieli Group achieves a net profit of 135.1 million euro By our news bureao ABSTRACT In the financial year to June 30,2009, the Danieli Group achieved a net profit of 135.1 million euro compared with that of 145.6 million euro in the same period of last year. For the year to June 30, 2009, the principal income and financial numbers were:
The 3% increase in sales and other income compared with the previous financial year essentially reflected processing of the large volume of orders taken during the previous period by the plant making segment, in spite of lower production in the steel making segment, with no significant changes in the consolidation and without any significant impact from euro-USD exchange rate movements. The substantial amount of research costs and the accruals made to cover potential charges on completion of some orders and for outstanding disputes, limited growth in the operating profit, but produced a satisfactory profit in spite of this, due also to shrewd financial management by the Group. Enhancement of BOF Productivity Through Modification of Hot Metal Transfer Ladle Lining at Durgapur Steel Plant By S. Sarkar, T.K. Pal, N.K. Ghosh, S.K. Garai, P. Chintaiah & M.K. Kujur, Research & Development Centre for Iron & Steel, Ranchi and A.N. Mishra & P.K. Datta, Durgapur Steel Plant, Durgapur ABSTRACT Durgapur Steel Plant (DSP), a unit of Steel Authority of India Limited (SAIL), along with Research & Development Centre for Iron and Steel (RDCIS) of SAIL took up a joint project to enhance the heat size of Basic Oxygen Furnace (BOF) that would enable the shop to increase production. The paper describes the technical approach with details of modifications carried out in hot metal transfer ladle (HMT) lining and its benefits towards achieving higher heat size in converters. Ladle lining pattern was optimised through study of metal jamming and its removal practices. Two experimental HMT ladles were modified with the introduction of Al2O3-SiC-C refractories along with provision of insulation keeping in mind the existing EOT crane capacity. Frequency of ladle repair was reduced from every 110 heats to every 153 heats on an average due to less mouth jam and skull formation allowing lower cost, reducing man hour, improving the availability of ladle and ensuring safe operation. The experiment resulted in increase in BOF heat size with a record HMT ladle lining life of 2443 heats. Shop has introduced the modified lining design in all ladles with an aim to enhance BOF productivity. Abstract of the Speech of Mr. L.N. Mittal, Chairman, World Steel Association, at the Annual Conference in Beijing By our correspondent ABSTRACT On behalf of all our members, I would like to start by thanking our Chinese colleagues for graciously hosting us here in Beijing. Not only do we have a very interesting and thought-provoking conference to look forward to, but we also have some fascinating cultural venues for the evening dinners. So thank you to everyone who has put so much effort and thought into ensuring this is an enjoyable as well as productive three days. It was only five years ago at this same conference in Istanbul that the leading Chinese steel companies and the Chinese Iron and Steel Association joined this Association. To our Chinese colleagues, we hope that you feel the benefits of your membership. Certainly we are a more complete Association thanks to your involvement. Our vision for this organisation is very much that it represents the interests of all steel companies, whether from Europe, The Middle East, Africa, Asia or the Americas. Of course we are competitiors, but we also share a love for the product we produce – a product that is crucial in building the infrastructure of our world. As such it is important that we have a platform at which to share and exchange our views on a truly global basis. It has been my privilege and honour to be the Chairman of this Association during the last twelve months, despite the very turbulent time the world has faced. I must admit when I accepted the Chairmanship I thought it would be a much more straightforward task. At that time we were all basking in the warmth of a period of sustained high demand for steel, where the biggest worry was whether there was the capacity to cope with this demand growth. Instead it has coincided with the biggest economic crisis the world has experienced since the Second World War. STAHL 2009 By our correspondent ABSTRACT Dusseldorf is coming alive once again with the international annual event STAHL 2009 at CCD Congress Center in Dusseldorf on the 12th of November 2009. STAHL 2009 brings innovative presentation, interesting discussions and good conversation for all its visitors. The STAHL event this year will last only one day but the deliberations will undoubtedly remain as interesting as ever. After the talks on steel, the delegates will have an opportunity to informally end the day through mutual interaction with the colleagues and business associates in the restaurant area of CCD. 2009 has been one of the steel industry‘s weakest years in the postwar period. As in other parts of the world, steel demand in Germany has decreased dramatically. Production has fallen as never before. During such economically difficult times, in particular, it is important to remove obstacles and look ahead. Against this background, the STAHL 2009 annual event will take place under the motto “Opportunities and Prospects”. In six Talks about Steel, respected speakers report on current political, economic and technical issues, also against the background of the changed situation: Which strategies are now necessary for coke, hot metal and steel production? Will the crisis bring about a renaissance of old challenges? What do these developments mean for human resources work in steel companies? These and other interesting matters will be discussed. STAHL 2009 will examine central social issues and discuss the performance and prospects of the Stahl-Zentrum at the Members‘ Meetings.

Successful startup of the new slab caster for stainless steels at ThyssenKrupp Acciai Speciali Terni, Italy By our correspondent ABSTRACT The new slab caster is designed for a productivity of 900,000 tpy of slabs covering the complete range of stainless steel grades, including AISI 200, 300, and 400 families (austenitic, ferritic, and martensitic grades). Slab sizes range from 800 to 1600 mm in width, and 5 to 11 m in length; 215 mm thickness is being considered (cold slab). The startup of the new caster has been flawless and, quality-wise, has earned the full satisfaction of the customer. In fact, the quality reports issued on the coils produced from the slabs coming from the new caster and processed in the downstream hot rolling and cold rolling facilities, state that the material perfectly matches TKAST’s superior quality standards, since the first heats. Already within the first week of production the caster had been able to operate in sequences of up to five heats, limited only by the present order backlog. The caster features a vertical-curved design, with a vertical portion exceeding 2.8 m in length, a main radius of 8.5 m, and a metallurgical length exceeding 27m, allowing casting speeds of 1.45 mpm for austenitic grades and 1.35 mpm for ferritic and martensitic grades. This new Danieli reference plant is the application of the order placed on June 6, 2007, and covering the dismantling of an existing SMS CSP caster and the supply, installation, and commissioning of a new single-strand conventional slab caster on the existing foundations. Top performances in thin slab casting at POSCO Gwangyang Works, Korea By our correspondent ABSTRACT In less than 3 months from startup, the new generation of Danieli TSC has already reached production peaks of 290 tph. In May 22, 2009, Posco held a ceremony to celebrate the successful completion and start up of the new, eco-friendly steel manufacturing plant, called High Mill, conceived for HRC production, marking a new milestone in casting and hot rolling technologies. The event was attended by Posco CEO Mr. Joon Yang Chung, Posco COO Mr. Nam-Seok Heo, Posco General Superintendent of Gwangyang Works Mr. Noe-Ha Cho and Danieli COO Mr. Franco Alzetta. This plant, which significantly advances the performances of thin slab casting and rolling technology, was developed successfully by a joint effort of Posco and Danieli teams, in only about 18 months from the contract’s effectiveness, and with its innovative technological, maintenance and layout solutions represents the most productive minimill for flat products ever conceived: it is equipped with the fastest thin slab caster ever installed and was conceived to reach a productivity of 1.8 Mtpy, with just one casting strand and maximum strip width of only about 1300 mm. Posco installed a minimill at its Gwangyang plant in 1996. to produce HRC. The plant design was based on the ISP layout and supplied by the consortium of DEMAG and Mitsubishi. Posco accumulated more than 10 years of operating experience with this plant, as well as powerful research capabilities. In 2007, after many trials and developments, Posco finally decided to revamp the existing casting and rolling facilities completely, in order to overcome the limitations of the original plant. In order to reach this ambitious goal, Posco selected Danieli as technological partner, thanks to its recognized experience in the design of high-speed thin slab casters and HSM facilities, as well as in process automation. The original plant was comprised of two single-strand thin slab casters connected to two roughing stands for each line, originally supplied by Demag. After the roughing stands, the transfer bars from the two strands were coiled and then conveyed to a single finishing mill line, originally supplied by Mitsubishi. Due to technological limitations of original plant, Posco was not satisfied of the results and decided to completely change the plant layout, awarding Danieli the contract for this exciting challenge. In place of the original two thin slab casters, a single, new-generation Ultra High-Speed Danieli Thin Slab Caster has been installed and commissioned. Developed in co-operation with Posco operating and research teams, the new caster, designed to cast 80 mm thick slabs at 8 mpm -unprecedented in industrial plants- represents the evolution of the already record-breaking Danieli fTSC (flexible Thin Slab Caster) enhancing to a new technological level the outstanding quality and productivity performances already proven in Danieli plants. The new caster design features solutions that were developed specifically to ensure productivity that will be nearly double the existing consolidated standard for thin slab casting technologies.
