TWO ITALIAN COMPANIES– ARLENICO AND FERALPI RELY ON SMS GROUP MEERDRIVE®PLUS TECHNOLOGY FOR THE PRODUCTION OF REBAR AND WIRE ROD

Arlenico SpA and Feralpi Siderurgica SpA, two key Italian wire rod producers, have each ordered a four-stand MEERdrive®PLUS finishing block from SMS group within one week. Both wire-rod finishing blocks will be integrated in the companies’ existing plants.

Arlenico, part of the Duferco Italia Holding, a special quality wire rod producer located beside the Lecco Lake, chose the four-stand MEERdrive®PLUS block to be installed in the existing wire rod line at its Caleotto plant. This will allow the company to serve the market with products of the tightest tolerances ever produced, as thanks to the heavy-duty machine supplied by SMS group and a sophisticated water cooling line included in the project, it will for the first time be able to apply the thermomechanical rolling process.

Feralpi, producer of rebar and wire rod for construction in Italy, located beside the Garda Lake, is investing in the four-stand MEERdrive®PLUS block in order to increase production and the rolling speed and be able to extend the size range produced and achieve enhanced final mechanical properties. Also in this case a sophisticated water cooling line will serve the four-passes wire rod sizing block.

MEERdrive®PLUS is a variant of the MEERdrive® technology, a revolutionary drive concept for modern wire rod production. It uses individual drives with small low-voltage motors for each stand. Since all finished sizes are rolled in the MEERdrive®PLUS block, it is possible to realize “one-family rolling” in the rolling mill reducing the otherwise required mill downtimes for size and ring changing.

The MEERdrive®PLUS blocks, which will both be installed after an existing ten-passes block, will be four-stand “oval-round-round-round” sizing blocks, capable of rolling wire rod diameters from 4.5 milli­meters up to 27 millimeters at speeds up to 120 meters per second – also at a temperature as low as 750 degrees centigrade. Excellent tolerances down to 0.05 millimeters and 50 percent ovality can be achieved.

These two new finishing blocks to be supplied to Arlenico and Feralpi are references number eleven and twelve, documenting the long success story of the MEERdrive® technology which started with block number one supplied to Sinobras in 2007. Arlenico and Feralpi will benefit from a wide range of outstanding economical and operational advantages. For example, it will be possible to reduce the required roll inventory to a minimum.

NORDIC STEEL MARKET ROUNDUP FROM MEPS

According to MEPS, hot rolled coil transaction figures are largely unchanged across the Nordic region. Demand from the construction sector is strong in some areas. In Finland, producers continue to seek substantial price hikes but customers are resisting. They may have to concede a rise next month.

Consumption of hot rolled plate is satisfactory. We have reports of increased selling figures bring proposed for May/June deliveries in Finland. However, we have no confirmation of deals being agreed at these new levels.

Supply of cold rolled material is tight. Major EU mills are fully booked until June. Many buyers are sourcing material from outside Europe. Delivery lead times are extending. Buyers expect increased values for second quarter contracts.

Delivery lead times for coated coil are long. Supply problems were amplified by the threat of antidumping action, with purchasers wary of buying from China and Russia. Further price hikes are foreseen.

Demand for wire rod is reported to be steady. Steelmakers’ scrap costs have risen. Consequently, buyers believe that an uptick in selling values is likely, in the near term.

Sales tonnages for rebar are healthy. Construction activity is at a high level, especially in Sweden. Tight scrap supply led to price increases in some countries. Buyers foresee selling values climbing in the near future.

Primetals Technologies to modernize flat rolling block for Böhler Edelstahl in Austria

  • Plant to be fitted with new automation and drives technology
  • Further improvements to availability and product quality
  • New technology will increase energy efficiency and cut maintenance costs
  • “RollMaster” to handle generation and management of pass schedules

Primetals Technologies has won an order from Böhler Edelstahl GmbH & Co KG (Böhler Edelstahl), a company of the Special Steel Division of voestalpine, to modernize the flat rolling block at its Kapfenberg plant in Austria. The plant will be equipped with a new drives- and automationsystem. The “RollMaster”, specially developed for long product rolling mills, will handle the generation and management of the pass schedules. The project is designed to increase plant availability, improve product quality, boost energy efficiency and cut maintenance costs. Modernization work is scheduled to take place during a one-month plant shutdown mid-2017.

The flat rolling block consists of three horizontal and two vertical stands, and produces flat bars in widths ranging from 43 to 205 millimeters and in thicknesses from 4.5 to 86 millimeters. A hydraulic drive system and a now obsolete, proprietary automation system have been in use since commissioning in 1988. Spare parts supply and adequate servicing can no longer be ensured. Böhler Edelstahl therefore decided to ask Primetals Technologies to completely modernize the automation and drives system. In previous years, Primetals Technologies has equipped the continuous rolling mill in the multiline rolling mill and the roughing stand of the blooming mill with new automation and drives technology, and supplied new drives for the six-stand HV-combination mill.

Primetals Technologies will be supplying new main and auxiliary drives with Sinamics S120 frequency converters, a new operator control and monitoring system based on Simatic PCS7, and new main gearboxes. The elimination of the hydraulic systems will reduce maintenance costs and increase plant availability which, in turn, will boost the productivity of the rolling line. Energy requirements as well as the consumption of hydraulic oil and cooling water will fall substantially. In future the “RollMaster”, specially designed for long product rolling mills, will handle the generation and management of the pass schedules. This software is the link between the production planning system and the plant automation. Primetals Technologies will also handle engineering, manufacturing, commissioning and customer training.

Böhler Edelstahl employs more than 2,000 people, and produced some 162,000 metric tons of steel in fiscal 2016. The company specializes in the production of long products and open-die forgings made of tool steel, high-speed steel, special materials and nickel-based alloys. Böhler Edelstahl GmbH & Co KG was founded in 1991 and is a wholly owned subsidiary company of voestalpine Edelstahl GmbH.

Energy-efficient electric melt shop and continuous caster for high-quality slabs at PT. Gunung, Indonesia successfully commissioned by SMS group

SMS group  has successfully commissioned an electric steel plant with efficient environmental technology and a single-strand continuous slab caster at PT. Gunung in Bekasi (West Java province), Indonesia.

The melt shop with the ARCCESS® electric arc furnace and a ladle furnace is designed for an annual production of 1.2 million tons of steel to be cast into slabs on the new continuous caster.

SMS group supplied the complete basic and detail engineering, the mechanical and electrical core components and the supervision of erection and commissioning. The SMS group scope of supply furthermore includes the complete X-Pact® electrical and automation system including Level 2 automation and commissioning according to the tried and tested “Plug&Work” concept.

B.K. Dutta, General Director: “The new works is of high strategic importance to us. Until now, we had to purchase slabs. By producing slabs ourselves, we do not only achieve a higher creation of value, but also ensure high quality thanks to the plants supplied by SMS group. Of course, all our plants are energy-efficient and easy on the environment. That is why we purchased them from SMS group.”  SMS group supplied an 120-ton ARCCESS® electric arc furnace and a 120-ton ladle furnace for the new steelworks complex. The range of charge materials for the electric arc furnace includes scrap, HBI (Hot Briquetted Iron) and hot metal.

Electric arc furnaces of the ARCCESS® series are optimized for highly efficient use of electrical and chemical energy. The electric arc furnace at PT. Gunung is equipped with the latest generation of the patented SIS (SMS Injection System) oxygen injection system, which combines innovative injection and burner technologies. This concept proves its worth through high productivity while keeping production costs low.

SMS group has equipped the electric arc furnace with a gas cleaning system. The dust-laden gases arising at the furnace and ancillary plants during the steelmaking process are efficiently captured and reduced to a residual dust content of less than 10 mg/Nm³. The system is operated by speed-controlled fans which consume a minimum of electrical power as the suction capacity is optimized depending on the specific process.

The continuous caster is designed for the production of slabs with thicknesses of 220 and 250 millimeters and widths from 800 to 2,100 millimeters. The range of grades produced will comprise structural steels as well as pipe and heavy-plate grades.

The segments are equipped with STEC-Roll® technology. Rolls of this technology optimize the casting process and set new standards for cost-effective maintenance and servicing, thanks to their long service life and the possibility of re-using them.

The continuous caster is equipped with modules from the ISC® (Intelligent Slab Casting) package, which ensure optimal plant productivity and slab quality. These modules include the hydraulically actuated resonance oscillation system, the mold with remote-adjustable narrow faces for changing the slab width during casting, as well as the Mold Monitoring System.

The horizontal part of the strand guide system uses position-controlled CyberLink segments. Dynamic Soft Reduction® in combination with the metallurgical process model DSC® (Dynamic Solidification Control) to control secondary cooling allows the production of slabs with perfect internal quality.

On the new plant, PT. Gunung produces high-quality slabs for further processing in its own Steckel and heavy plate mills.

At the Bekasi location, PT. Gunung operates a long-product line for the production of sections and wire rods, as well as a flat-product line for the production of heavy plates and pipes. All major production lines were supplied by the SMS group.
