Successful Modernization of AOD Converter at SěAH CSS

Reduced maintenance costs thanks to SMS group torque retainer on AOD converter tilt drive

The 100-ton AOD converter at the SěAH CSS stainless steel mill in Changwon, South Korea, was successfully re-commissioned in March 2018, after installation of an electro-hydraulic torque retainer from SMS group.

The purpose of the modernization was to minimize the destructive forces acting on the gears, bearings and converter car during gas injection.

The scope of supply of SMS group comprised an electro-hydraulic torque retainer including electrical equipment and automation systems as well as the supervision of erection and commissioning.

The installation of the torque retainer was performed during a scheduled maintenance standstill and completed within ten days, including cold and hot commissioning. Hot commissioning even took place two days ahead of schedule under regular production conditions. The guaranteed values were fully reached. Thanks to the new electro-hydraulic torque retainer from SMS group, the dynamic loads on the entire converter equipment have been significantly reduced. This is the result of the successful cooperation between the teams from SěAH and SMS group.

Seungheon Lee, General Manager Steelmaking Facility Team: “The new torque retainer from SMS group has significantly reduced the vibrations of the AOD converter. We experience the benefits of this modernization every day. Maintenance costs will be reduced significantly. We are very satisfied.”

SěAH Changwon Integrated Special Steel produces stainless steel, tool steel and carbon steel at a production volume of 1.2 million tons per year. The produced high-tech steel grades are used in a wide range of applications, for example in vehicles, machinery, aircrafts, nuclear power plants, shipbuilding and electronics.

Primetals Technologies received PAC from ArcelorMittal Poland for second LD converter

  • Converter entered service on schedule in February 2018 in the Dąbrowa Górnicza plant
  • A first converter had entered service on schedule at the end of November 2016
  • Vaicon Link 2.0 maintenance-free converter suspension offers a long service life

 

Primetals Technologies has received the Provisional Acceptance Certificate (PAC) from ArcelorMittal Poland S.A. for the replacement of the second LD(BOF) converter at its Dąbrowa Górnicza steel works. Like its counterpart, Converter #1 – already replaced by Primetals Technologies and commissioned in November 2016 – Converter #3 was a turnkey construction. Its replacement had already been agreed as an option in the third quarter of 2015. The second converter will also be suspended by the maintenance-free Vaicon Link 2.0 which not only has a long service life but also minimizes the stresses caused by thermal deformations.

The converters previously used in the Dąbrowa Górnicza steel works had reached the end of their life cycles. As in the case of Converter #1, Primetals Technologies supplied the vessel and the trunnion ring, including the maintenance-free Vaicon Link 2.0 suspension, for Converter #3. The converter bearings and the enclosure have also been renewed. The order included also removal of the existing vessel and assembly and installation of the new equipment. This had been handled by ZKS Ferrum S.A., the Polish partner in the consortium.

ArcelorMittal Poland is the leading steel producer in Poland, operating six production plants in the south of Poland. Its range of products includes profiles, rails, fittings for the construction, transport and mining industries, as well as flat products for the automotive industry and domestic appliances. The Dąbrowa Górnicza plant specializes in producing heavy profiles. It is also one of a few plants worldwide able to produce 120 meter long rails.

Flat Product Steel Prices Stable in the Nordic Region

Hot rolled coil consumption is steady, in Denmark. Regional mills sought price increases, this month, but buyers resisted, according to the latest edition of MEPS European Steel Review Supplement. In Sweden, while demand from the building sector declined, a little, the overall economy is strong. This is reflected in healthy steel sales volumes. Purchase tonnages are stable, at a high level, in Finland. In Norway, purchasing activity is brisk but is not predicted to increase significantly.

The plate market, in Denmark, is a little subdued but a pickup is predicted, in the near term. European mills continue to push for price increases. However, end-users believe that transaction values are too high and, consequently, stockists are reluctant to agree to the producers’ proposals. Third country import offers are rising. In Sweden, contract prices are up, for quarter two, but the trend in spot values has levelled out. Industrial consumption is healthy. Plate demand is good, in Finland. Selling values are at a high level but did not increase, this month. Producers’ delivery lead times are extending, in Norway. Demand, from machinery manufacturers and the offshore energy sector, is growing.

Buyers, in Denmark, are finding the availability of cold rolled coils, from EU mills, limited. They are, therefore, purchasing more from third country suppliers. The requirement from the manufacturing sector is strong, in Sweden. Sales volumes and transaction values are high. The Swedish currency continues to weaken. Cold rolled coil consumption is steady, at a satisfactory level, in Finland. Prices, are unchanged, in April. Demand is fair, in Norway. However, customers are buying only for their immediate needs, as they expect prices to decline, soon.

In Denmark, the coated coil market remains strong and supply is still restricted. This will begin to ease when ArcelorMittal restarts its galvanising line, in Belgium. For now, prices for thin gauge material are rising but those for MEPS’ benchmark products are unchanged. In Sweden, carmaking activity is very strong and demand from the industrial sectors, generally, is more than satisfactory. Finnish suppliers continue to report good sales to the auto supply chains in neighbouring Sweden and Germany.

The MEPS Global Steel Price Reaches Three-Year High

According to the September edition of MEPS International Steel Review, steel prices around the world have been on an upward trend since July. The company’s global all products steel price is at its highest level since September 2014.

Steelmakers announced a series of price increases, during the third quarter. Asian and European steel buyers appeared to offer little resistance to the mills’ pricing initiatives, due to a shortage of competitively priced third country imports, notably those from China.

In the absence of low-cost alternatives, Far East and European steel manufacturers took the opportunity to raise prices, in an attempt to recoup their escalating raw material outlay. In contrast, North American producers had limited success, in lifting selling figures, despite the uptrend in international prices. In recent years, a rise in North American selling figures prompted subsequent price increases in other parts of the world.

The MEPS world average steel selling figure is forecast to decrease, marginally, in the final quarter of 2017. An improved pricing environment in Europe is expected to be more than offset by weaker conditions in North America and China.

End-user demand, traditionally, declines during the fourth trimester. Distributors tend to draw down their stock levels for the year-end. These factors are likely to exert negative pressure on transaction values.

Steelmaking raw material costs have declined, in recent weeks. However, mill outlay on consumables, such as electrodes and refractories, has surged recently. This is likely to minimise the downward movement in steel selling figures, in the coming months.

MEPS EU Average Flat Product Prices Slip But Long Product Values Recover

Flat product prices continued to fall in the latter part of June, in both the north and south of Europe. Basis numbers were driven down by the impact of inventory build-up and price pressure from third country imports. Market sentiment began to change in early July, as competition from overseas material reduced. Foreign offer prices increased and the expectation of the introduction of antidumping duties, on hot rolled and hot dipped galvanised coil, during the summer, also led to fewer import transactions. An extended period of destocking is coming to an end. End-user consumption is at a high level and service centres are beginning to re-order for the autumn.

Reacting to this change in market direction, a number of Western European steelmakers are now pushing for price increases of around €20/30 per tonne on all strip mill products, for September deliveries.

European long product producers began to target price hikes of €15/30 per tonne, at the start of July, citing higher input costs. So far, the response from buyers is fair. At least a part of the increase is likely to be achieved. The mills are bullish and, in some instances, they are already pushing for further increases.
