Primetals Technologies to engineer continuous caster and secondary metallurgy facilities for MMKI

  • Annual production capacity to increase to four million metric tons of slabs
  • Project includes ladle furnace, alloying station and dedusting system
  • Expanded product portfolio
  • Cross-section heat-pacing solution to coordinate steel production with casting operation
  • Reduction of dust content in cleaned gas

Primetals Technologies has received an order from Ukrainian steel producer “Iljitsch” Metallurgical Combinate in Mariupol (MMKI) to engineer a continuous slab caster, a twin ladle furnace with an alloying station, and the associated dedusting system. The two-strand caster CC4 will be designed to produce 2.5 million metric tons of slabs per annum. This will increase MMKI’s annual production capacity to around four million metric tons, as well as enhancing and expanding its product portfolio to include, for example, HC, UHC and ULC steels. A level 3 heat-pacing solution will coordinate the steel production with the casting operation.

MMKI produces steel with three LD (BOF) converters. A new 150 metric ton twin ladle furnace from Primetals Technologies and the associated alloying station will be used to help set the desired steel grades and the correct casting temperature. A transformer with a rated power of 28 MVA will provide the electrical energy for the ladle furnace, enabling a heating rate of 4.5 °C per minute. Primetals Technologies will design a dedusting system to clean the offgases from the ladle metallurgy facility. This will process around 206,000 standard cubic meters per hour, and reduce the dust content of the cleaned gas to less than twelve milligrams per standard cubic meter.

The engineering order for the continuous slab caster covers all the installations from the ladle turret and the ladle car through to the exit zone with its weighing, torch cutting, marking and deburring machines. The caster from Primetals Technologies will have a machine radius of nine meters and a metallurgical length of 29.8 meters. It will cast slabs with thicknesses of 170 and 250 millimeters in widths ranging from 900 to 1,550 millimeters. The maximum casting speed will be 2.2 meters per minute. It will process peritectic and peritectic alloyed steels, low, medium, high and ultra-high carbon grades, as well as medium-carbon alloyed steel. The caster will be equipped with automatic LevCon mold level control, a straight, cassette-type Smart Mold with the DynaWidth technology package to automatically adjust the width of the slab online, and the DynaFlex mold oscillator. The strand guide will be equipped with smart segments and I-Star rollers. DynaGap Soft Reduction, the Dynacs 3D secondary cooling model, and DynaJet nozzles will also be installed, making it possible for MMKI to produce a wide variety of high-quality grades. The interior quality of the slabs will also be improved.

MMKI is one of the largest iron and steel works in Ukraine, The company produces a wide range of flat products made of carbon, low-alloyed and alloyed steel grades for various applications. These include heavy plates for pipelines, shipbuilding, pressure vessels and the construction industry, as well as hot and cold rolled plates and coils. Primetals Technologies previously supplied continuous slab caster CC3 to Mariupol, where it has been in operation since 2005.

US FLAT PRODUCT STEEL PRICES ESCALATE IN JANUARY

US flat product transaction values advanced, in January, to halt the negative pressure on steel prices for much of last year.

In December, North American steel mills announced price hikes of up to US$40 per short ton. Local producers escalated list prices for a second time, this month, following higher scrap prices.

In January’s edition of the International Steel Review, MEPS reports that higher transaction values have been noted as customers restock following the seasonal holidays. Buyers may not accept further increases as delivery lead times remain short.

In China, flat products selling values strengthened in early January as major producers announced increases. However, domestic transaction values softened recently as the Lunar New Year approaches.

High import penetration of Chinese exports have put further negative pressure on domestic South Korean transaction prices.

In Poland, selling figures stabilised, this month, despite market activity remaining muted following the Christmas holidays. In contrast, Czech/Slovak transaction values fell further as local producers offered discounted prices to secure orders.

BRIC STEEL PRICES TUMBLE FURTHER, IN JANUARY

BRIC steel prices continue to slide because of weak demand and global oversupply.

In the recent edition of the Developing Markets’ Steel Review, MEPS report that the BRIC average transaction price, softened, in January, across flat and long products.

Russian steelmakers offered discounted prices to secure mill output, in January, although we expect transaction values to rise next month. The Brazilian steel industry is being negatively affected by the poor economic climate domestically.

Turkish selling values mainly fell because of rising imports and muted demand.

However, domestic transaction prices for Chinese flat products advanced as local producers announced price hikes early, in January. As the Lunar New Year approaches, values have weakened as domestic consumption slows down.

NORDIC STEEL MARKET ROUNDUP FROM MEPS

Nordic steel prices continue to be under pressure because of weak demand, overcapacity in Europe and a continuing high level of import penetration of non-EU material.

In January’s edition of the European Steel Review Supplement, MEPS reports that domestic transaction values throughout the region are either stable or slightly falling across flat and long products.

However, European mills have talked over price increases for first quarter business. Buyers have resisted these moves, at the time of writing, as sales activity is slow following the seasonal holidays.

Continuous bloom caster and long-product rolling mills from Primetals Technologies started up at Hyundai

  • Installations are part of Hyundai’s new special steel mill in Dangjin
  • Continuous caster produces 1.1 million metric tons of blooms per year
  • 200th application of monitoring system Mold Expert
  • Large bar mill produces annual total of one million metric tons of end products and billets for the small bar and wire rod mill

In October 2015, a continuous bloom casting machine, a large bar rolling mill and a small bar and wire rod mill supplied by Primetals Technologies were started up at the new special steel mill of Korean steel maker Hyundai Steel in Dangjin. The caster is designed to produce 1.1 million metric tons of blooms per year. It features the 200th application of the monitoring system Mold Expert. The large bar rolling mill produces one million metric tons of end round products as well as billets for the small bar and wire rod mill. The order had been awarded to Primetals Technologies in early 2014. Both caster and large bar rolling mill were started up almost a month ahead of the scheduled date.

Hyundai Steel, situated in Incheon and Seoul, South Korea, belongs to the Hyundai-Kia Automotive Group and runs six production facilities in South Korea and a further one in China. At present, the company is constructing a new plant at the Dangjin site to produce special steels for the automotive industry. In future, bar and wire are to be produced here as primary material for engine and gearbox parts. Annual production of 400,000 metric tons of wire rod and 600,000 metric tons of straight bar and bar-in-coil is planned.

The four-strand continuous bloom caster from Primetals Technologies has an annual capacity of 1.1 million metric tons. The caster is equipped with mold-monitoring system Mold Expert. In combination with air mist spray cooling and interior-cooled rollers in the strand guidance system, further technology packages ensure uniformly high quality of the blooms cast. Still hot, these are then fed for direct use in the bar line. This saves energy during reheating and improves operating safety because there is no need for transport of blooms, for example by crane.

The large bar mill encompasses a duo reversing breakdown stand and a finishing train with rolling/sizing stands. The large bar mill also provides billets to be further processed in the small bar and wire rod mill, which Primetals Technologies also supplied. This combination mill has a capacity of 800,000 tons and is designed to roll 160 tons per hour. It includes a continuous roughing and intermediate mill feeding a sizing block supplied by Germany-based Friedrich Kocks GmbH & Co KG for production of bars, a rod outlet with a rod Reducing Sizing Mill (RSM) and also a bar-in-coil (BIC) outlet. Both the rod and BIC outlets have slow and fast cooling capability. The small bar and wire rod mill has the highest production rate for a combination mill, and is particularly designed for low-temperature rolling. This improves the metallurgical structure and mechanical properties of end products and enhances flexibility during the rolling operation.

Special mechatronics packages and an integrated automation solution ensure the necessary high product quality throughout the plant.

Tata Steel UK Limited announces cost reductions at its UK businesses to improve competitiveness

Tata Steel UK Limited, an indirect subsidiary of Tata Steel Limited, has today announced cost-saving proposals to improve the competitiveness of its UK business.

The plans would lead to the loss of 1,050 jobs – 750 jobs at its Port Talbot-based Strip Products UK business, 200 jobs in support functions and a further 100 jobs at steel mills in Trostre, Corby and Hartlepool.

The proposed changes follow continued falls in the European steel price caused by a flood of cheap imports, particularly from China.

A full consultation process with employee representatives will begin immediately.

Karl Koehler, Chief Executive of Tata Steel’s European operations, said: “I know this news will be unsettling for all those affected, but these tough actions are critical in the face of extremely difficult market conditions which are expected to continue for the foreseeable future.

“We need the European Commission to accelerate its response to unfairly traded imports and increase the robustness of its actions. Not doing so threatens the future of the entire European steel industry. And while we welcome progress on UK energy costs, the Government must take urgent action to increase the competitiveness of the UK for its vital steel sector. This includes lowering business rates and supporting energy efficiency and anti-dumping cases so we can compete fairly.

“Tata Steel has been a hugely supportive investor, and has invested £1.5 billion in its UK operations. We now need all stakeholders to do their utmost to meet the unprecedented challenges the steel sector is facing.”

Stuart Wilkie, Director of Strip Products UK, said: “We have to accelerate the changes we announced last August, by lowering our costs at the same time as focusing on manufacturing higher-value products. These are urgent steps needed to give this business a chance of survival.

“We will work closely with affected employees and their trade union representatives. Retaining the right skills for the future will be critical, but we will look to minimise employee hardship and redeploy employees where possible.”

Tata Steel’s regeneration arm UK Steel Enterprise will look at how it can provide more support to the local communities affected by today’s announcement and help stimulate new job creation in those areas. Over the last four decades the company has helped to regenerate local economies, including South Wales, with £88 million of support and created more than 75,000 new jobs across the UK.
