    Steam of hot flue gases saves energy at steel mills

    A new solution from Siemens takes advantage of hot flue gases from arc furnaces to generate steam. This steam can then be used for other steel mill processes or for generating electricity. In the past, flue gases were usually not utilized, so the energy they carried was lost. The system consists of steam boilers, pipes, water tanks, and pumps and can be directly integrated into the existing flue gas cooling system. Theoretically, the system could entirely replace conventional cooling.

    A feasibility study carried out at a steel mill in Turkey revealed potential savings of 44.5 KWH of electricity per ton of steel produced. That corresponds to around ten percent of the electrical energy that is normally required. If the steam were used to preheat the feed water for the steel mill's power plant, for example, the mill would save 45,000 tonnes of coal per year.

    Electric arc furnaces melt steel scrap under arcs heated to a temperature of about 3,500 °C using high-voltage electricity. Depending on the specific furnace operation, up to one third of the energy used escapes in the flue gases. Normally these flue gases which can be as hot as 1,800 °C - are extracted from the furnace through water-cooled pipes. Because this cooling water circulates within a closed system, it cannot be permitted to form steam. Cooling towers dissipate the excess heat.

    This is where the solution developed by the experts at Siemens Metals Technologies comes in. The hot flue gas is diverted into a steam generator, where it flows around pipes filled with water. The heat from the gas turns the water into steam. A sophisticated system of nested heating surfaces ensures that heat is transferred from the flue gas as efficiently as possible. Special recirculation pumps ensure that the steam boiler is adequately cooled.

    The system can handle fluctuations in flue gas temperature and volume, and it is specially designed to deal with the high levels of dust, some of which is corrosive, in the flue gas. Continuous steam production, such as that required for generating electricity, can be achieved through the installation of optional storage buffers known as "steam accumulators."

    The heat from the flue gas can be recovered even more efficiently if the gas is directed through an "economizer" after it leaves the steam boiler. In the "economizer" the gas flows around a second system of pipes, where the remainder of its heat is used to preheat the feed water for the steam boiler.

    The steam generation system has a modular construction and can be easily adapted to the specific requirements of each plant. This makes it especially easy to modernize existing steel mills.

    Pangang orders continuous galvanizing line from Siemens

    The Chinese Pangang Group has given Siemens Metals Technologies an order to supply a new continuous galvanizing line for its Chongqing plant. The line will process 450,000 tonnes of high strength cold strip per annum for use in the automotive industry. For the first time in a Chinese plant, strips will be able to be optionally hotdip galvanized with GI and GA coatings or aluminized on a single line. The project is scheduled to be completed by the middle of 2015.

    Siemens will plan and supply the complete mechanical and electrical equipment as well as the automation for Pangang's continuous galvanizing line in Chongqing. The galvanizing line will coat deep drawing steels, hot formed and high strength steels, as well as dual phase steels with strip thicknesses ranging from 0.5 to 3.0 millimeters and widths from 800 to 1,600 millimeters.

    The maximum coil weight will be 34 tonnes. The total achievable coating thicknesses of both sides will lie between 50 and 350 grams per square meter.

    The scope of delivery from Siemens will start at the coil feed and the entry section with a double pay off reel, followed by a Siemens type LW21 laser welding system with strip centering. Both welding and cutting operations are carried out with laser technology. The laser beam is transmitted via fiber, no mirror is needed. Also, no mechanical shear is required, thus avoiding wear of cutting tools. This will produce a continuous strip, which will first pass into a 16-fold strip looper with a capacity of 430 meters. The strip will be cleaned in an electrolytic cleaning section, and then heated in an ART (all radiant tubes) furnace

    Hot dip galvanizing will take place two coating baths, a common one for GI and GA coatings and one dedicated to aluminizing coating. An induction furnace located above the air wiping system serves for galvannealing. The coated strip will then be tempered in a cooling section. This will be followed by an intermediate looper with a capacity of 280 meters. After that, the strip will be fed to a Siroll-4Hi temper mill with a roll force of 1,200 tonnes and a 25 tonne tension leveler. The shiftable Siroll Roll Coater will provide additional protection for the coated surfaces against corrosion and fingerprints at the last stage of post treatment.

    Finally, the strip will run through a 400 meters exit looper before it is side trimmed and its width measured. This will be followed by an inspection station, in which the strip surface quality is checked. The exit section will consist of an electrostatic oiler, a rotary shear and a single tension reel , as well as coil handling, strapping and weighing machines.

    The project will be executed by a consortium led by Siemens together with Andritz Selas and Andritz China. Siemens China will be responsible for the electrical equipment and the automation as well as the local mechanical engineering content.

    Siemens to modernize continuous slab caster for HKM

    Huttenwerke Krupp Mannesmann GmbH has awarded Siemens Metals Technologies an order to modernize slab caster no. 3 in its Duisburg Huckingen plant in Germany.

    The project is intended to enhance the quality and product tolerances of the slabs produced, to widen the range of products and to improve process stability, availability and safety at work. The casting plant will also be equipped with new basic and process automation, technology packages, such as DynaGap Soft Reduction, LevCon, DynaWidth and DynaFlex and new safety equipment.

    The air mist secondary cooling will also be renewed to optimize the temperature control in order to produce high quality slabs. Modernization is scheduled to take place at the end of 2014 during a temporary plant shutdown.

    The slab caster, which was delivered by a third party supplier, has been in operation at HKM in Duisburg since 2000. Consequently, the supply of spare parts for much of the electrical equipment can no longer be guaranteed over the medium term. It is also becoming more difficult to meet the ever more stringent requirements for process stability and safety at work regulations. HKM has therefore decided to replace much of the electrical equipment with new Siemens systems.

    In the course of the project, the plant structure will also be adapted, redundancies installed, and the plant functionality extended. This will increase availability and improve product tolerances. Siemens will also fundamentally overhaul the existing air mist secondary cooling and equip it with a DynaJet air mist system.

    Siemens puts three continuous slab casters into operation for TISCO

    In the last quarter of 2013, three continuous slab casters from Siemens Metals Technologies were put into operation at Chinese steel producer Taiyuan Iron and Steel Group Corp.

    Two of the casters were installed in Tisco's carbon and special-steel works in Taiyuan and the third in the company's stainless steel works at the same location.

    Each of the continuous casters is designed to produce one million metric tons of slabs per year. The new casters increase Tisco's capacity for manufacturing high-quality carbon, silicon and stainless steels. Siemens' technology packages ensure that they produce slabs with a high interior and surface quality.

    Tisco is China's leading producer of stainless steel. Two single-strand continuous slab casters, CCM 1 and CCM 2, from Siemens have been in operation in Steel Making Plant 2 North since 2007. Now that the third caster, CCM 0, has gone on stream, Tisco can produce an additional one million metric tons of stainless-steel slabs every year. The casting plant has a machine radius of nine meters and a metallurgical length of 27.4 meters. The thickness of the slabs can be varied between 180 and 250 millimeters and their width from 1,000 to 2,150 millimeters.

    The other two continuous casters, CCM 01 and CCM 04, were erected in Steel Making Plant 2 South, which is Tisco's carbon and special-steel works. CCM 01 replaces one of the two Siemens continuous casters which have been in operation there for many years. The two new casting plants are almost identical in order to optimize maintenance, operation and spare parts stocks.

    They have a machine radius of eight meters and a metallurgical length of 27.6 meters. The thickness of the slabs ranges from 200 to 230 millimeters and the width from 830 to 1,630 millimeters. The two plants cast a wide range of carbon steels and special steels with high silicon content, and each has an annual production capacity of one million metric tons of slabs.

    All three Siemens casters feature a cassette-type Smart Mold with a hydraulic DynaFlex mold oscillator. The plants are equipped with DynaWidth for automatic setting of the slab width, and Smart Segments are installed in the strand-guiding system. DynaGap Soft Reduction enables the position of the final solidification of the strand to be determined with high precision, which means the roll gap can be controlled precisely to ensure high internal slab quality. Dynacs dynamic secondary cooling and DynaJet nozzles, combined with internally cooled I-Star Rollers, produce a slab surface of consistently high quality.

    Siemens also supplied the complete basic (level 1) and process automation ) level 2) for the three casters and assisted Tisco with construction and commissioning.

    Hyundai orders continuous bloom caster and long product rolling mills from Siemens

    For a new special steel mill in Dangjin, the Korean steel maker Hyundai Steel has placed an order with Siemens Metals Technologies for a continuous bloom casting machine, a large bar rolling mill and a small bar and wire rod mill. Commissioning of the plants is scheduled for the end of 2015.

    Hyundai Steel, situated in Incheon and Seoul, South Korea, belongs to the Hyundai Kia Automotive Group and runs three 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 tonnes of wire rod and 600,000 metric tons of straight bar and bar in coil is planned. The four strand continuous bloom caster from Siemens has an annual capacity of 1.1 million.

    The caster is equipped with mold-level control and breakout protection. 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.

    Scunthorpe well positioned to benefit from Hull Siemens deal - TATA Steel

    Scunthorpe Telegraph reported that bosses at TATA Steel in Scunthorpe said they are delighted at today's news that Siemens will invest GBP 310 million in wind energy in the Humber region.

    And they said that the town site is well positioned to benefit from the work the development will bring. The German energy giant has committed to two new sites in Hull and Paull, building and assembling wind turbines for offshore farms.

    The move is expected to create 1,000 direct jobs and thousands more in the supply line and will cement the Humber region's position as the UK's green energy leader.

    A TATA Steel spokesman said that "We are delighted to see confirmation of this investment in the UK's renewables energy industry. The infrastructure necessary to develop new sources of renewable energy requires large volumes of steel and in recent years we have invested in facilities at Scunthorpe and Hartlepool to meet this need. We will continue to work with our customers and others in this new industry to ensure that we're well positioned to benefit from its growth and that where possible the economic benefits of that growth are retained within the UK."

    The leader of the main Scunthorpe steel trade union Community was the first to welcome the GBP 310 million investment by Siemens in Hull.

    Mr Roy Rickhuss general secretary of Community said that "This should be good news for Tata Steel in Scunthorpe as well as the region. However, it's important that the right supply chains are put in place. When there's a first-class steelworks nearby that should be able to deliver the steel that Siemens requires, it's important that there are early discussions to capitalise on this opportunity. This is welcome news, which, with the right approach, should help to secure steel jobs in Scunthorpe.”

    Mr Paul Reuter national steel officer for the Unite trade union said that "This is potentially very good news for our members at TATA Steel, Siemens and the UK economy.

    Mr Sean Scorer chairman of the Scunthorpe TATA Steel works multi union committee said that “This is an extremely positive development for manufacturing in the Humber region. I'm assured Tata Steel product development experts are working hard with the developers of this scheme to ensure a positive spin off for TATA Steel and our associated manufacturing supply chain partners. We will be utilising our resources and influence to help secure a brighter future for Scunthorpe."
