EU supports testing of groundbreaking iron production technology

stahl und eisen - 

The European Union has agreed to contribute 7.4 million euros towards testing a groundbreaking new iron production process being developed at Tata Steel’s IJmuiden steelworks in the Netherlands. The 6-month test campaign of the HIsarna pilot plant in 2016 will establish whether the new technology can produce molten iron in a stable way over a sustained period of time. The EU’s support represents nearly a third of the 25-million euro test costs next year. If the technology is viable and can be scaled up successfully, it would enable further resource efficiency improvements in steelmaking – using the world’s limited resources in a more sustainable way while minimising impacts on the environment. Steel companies would be able to use a wider range of raw materials, including recycling materials, and the technology would lead to 20 % lower CO2 emissions. If successful, the HIsarna technology could deliver greater environmental and economic sustainability 10 to 15 years from now.

7/1/2015 - Roughing shear revamping project

AIC gets final acceptance certificate in Siderperu, Gerdau group

stahl und eisen - 

AIC has successfully accomplished the roughing shear revamping project in Siderperu, Tren 2, located in Nuevo Chimbote, Ancash/Peru and received the final acceptance certificate. The job consisted in replacing the complete automation and power control of the start/stop roughing shear installing a Siemens Simotion technology after a previous successful project regarding the cooling bed entry shears commissioned on last October, as to confirm the good job done at that time. The roughing shear has been brought from an AC motor and drive configuration to a DC configuration using SIEMENS Sinamics DCM drive to reuse a dc motor existing in plant and to improve cuts precisions. The collaboration started last year between Siderperu and AIC has been so strengthened with this job.

AIC is a global system integrator providing advanced and tailored automation solutions for the steel industry, with the aim to continuously improve both efficiency, competitiveness and safety of the production processes. With more than 800 applications worldwide and 40 years of history, AIC can boost an unique experience in both greenfield and revamping projects in long products rolling mills and continuous casting machines.

6/29/2015 - New in-depth study – China's state capitalism said to be biggest threat to industries’ existence in Europe

China wants the EU to recognise it as a market economy

stahl und eisen - 

A few days before the EU-China Summit on 29 June, an in-depth study by economists confirms that China is far away from being a market economy. Several hundreds of national, regional and sectoral five-year plans, pervasive state control over businesses, subsidies that have doubled over the past five years, and dumped exports financed by state-owned banks - these are only some examples of how the People’s Republic of China controls its industry.

6/23/2015 - Dumping investigations against China

Towards fair competition in Latin America’s steel industry

stahl und eisen - 

Following the meeting of the Steel Committee of the OECD (Organization for Economic Cooperation and Development) and the strong insistence of the steel industry on the damage that current overcapacity and unfair trade practices of China are causing to the global and Latin American steel markets, the governments of our continent are beginning to act in favor of ensuring a level playing field in regional trade. In Latin America, there are currently 27 resolutions in force against steel imports from China, and another 4 investigations in progress.

6/17/2015 - ABB systems chosen for South African blast furnace revamp

ArcelorMittal will expand production at its flagship KwaZulu-Natal steelwork

stahl und eisen - 

ABB, the leading power and automation technology group, has helped achieve a 12-% increase in liquid iron production following the electrical, control and instrumentation systems upgrade at an ArcelorMittal blast furnace and steelworks in South Africa. During a shutdown last year, ArcelorMittal South Africa invested heavily in relining and refurbishing the sole blast furnace and renewed the control system at its plant at Newcastle in the KwaZulu-Natal province. The investment, one of ArcelorMittal’s largest in South Africa, took two years to plan and six months to carry out. It will increase production from 1.7 million to 1.9 million t/a.

The upgraded blast furnace control system has 7 000 I/O points and uses ABB’s System 800xA, with seven redundant AC800M controllers. The system controls the overall blast furnace process including stockhouse and charging, the bell-less top, the casthouse, hot blast stoves, slag treatment, gas cleaning, water cooling system and pulverized coal preparation and injection. The control system includes alarm and asset management, enabling easier operation and maintenance of the blast furnace plant. The project involved integrating more than 300 Profibus PA devices and 200 HART devices to the System 800xA.

6/16/2015 - GMTN: Competition for students at the “Bright World of Metals“

Steel is not necessarily heavy – “Steel flies”

stahl und eisen - 

They are not difficult to transport: the flying objects that are competing against each other in the student competition “Steel flies” are extremely light. The futuristic flying objects that will be trying to win the title of the best plane in Hall 6 at the “Bright World of Metals” in Düsseldorf on 17. June weigh a maximum of 400 grams, less that two packs of butter. The little indoor planes are judged by how light they are, how innovative their design is and how long they fly. In other words: the one that is lightest and flies longest wins.

“Steel flies” has already become an established tradition in the meantime: for more than 15 years now, students from the universities of Aachen, Bremen, Darmstadt, Dortmund, Kassel and Saarbrücken have been experimenting with steel and have incorporated many innovative ideas in their planes during this time. After only three months of development time, the models are required to demonstrate their flying skills at the final of the flying competition in Düsseldorf during the four metal trade fairs GIFA, METEC, THERMPROCESS and NEWCAST.

6/15/2015 - Weaker domestic outlook pushed index below 50-point threshold

Platts China Steel Sentiment Index slumped in June

stahl und eisen - 

The outlook for new steel orders in China over June deteriorated from May, while expectations for flat steel prices over the coming month was also depressed, according to the latest Platts China Steel Sentiment Index (Platts CSSI), which showed a headline reading of 42.2 out of a possible 100 points. “Market sentiment is extremely pessimistic at the moment due to continued weak demand from domestic end-user segments, such as manufacturing and property construction,” said Paul Bartholomew, Platts managing editor, steel & steel raw materials. “This is expected to put downward pressure on flat steel prices, such as hot rolled coil, over the next month despite slightly higher iron ore input costs.”
