India: Gebr. Pfeiffer has announced that it has received an order for one MVR 6000 C-6 roller mill for Chettinand Cement Corp. Pvt. Ltd.’s upcoming 2.0Mt/yr Vishakapatnam granulated blast-furnace slag (GBFS) and slag cement
Grinding plant in Andhra Pradesh. Gebr. Pfeiffer said the mill will grind slag and cement to a fineness of between 3000 and 3800 blaine at a rate of between 235t/hr and 340t/hr. It says the mill improves plant availability by the active redundancy of the grinding rollers, enabling mill operation with reduced rollers in the event of maintenance work or a malfunction.

Sweden: Construction and engineering conglomerate Peab’s subsidiary Swecem has engaged German-based Gebr. Pfeiffer for the supply of one MVR 2500 C-4 grinding mill at its granulated blast furnace slag (GBFS) grinding plant in Oxelösund in Södermanland. The mill has four grinding rollers and a table diameter of 2.5m, giving it a 25t/hr slag grinding capacity.

Swecem operates a concrete plant in Kungsängen. It currently uses ground granulated blast furnace slag (GGBFS) supplied by Irish-based Ecocem’s 0.7Mt/yr Dunkirk grinding plant in France.

Luxembourg: ArcelorMittal plans to reduce its European steel production levels due to weak market demand and high import levels. It will reduce primary steelmaking production at its facilities in Dunkirk, France and Eisenhüttenstadt, Germany. Reduce primary steelmaking production at its facility in Bremen, Germany in the fourth quarter of 2019, where a planned blast furnace stoppage for repair works will be extended. It will extend the stoppage planned in the fourth quarter of 2019 to repair a blast furnace at its plant in Asturias, Spain.

“This is again a hard decision for us to have taken but given the level of weakness in the market, we feel it is the prudent course of action. This will be a temporary measure that will be reversed when market conditions improve. In the meantime, our employees remain our utmost priority and we are doing everything we can to ensure that the right social measures are in place to support them and their families during this difficult time,” said Geert van Poelvoorde, the chief executive officer (CEO) of ArcelorMittal Europe – Flat Products.

In early May 2019 ArcelorMittal announced its intention to temporarily idle production at its steelmaking facilities in Kraków, Poland and reduce production in Asturias, Spain. The announcement also impacted the planned increase of shipments at ArcelorMittal Italia to a 6Mt/yr run-rate. The planned increase will be slowed down following a decision to optimise cost and quality over volume in the current market environment.

Germany: The 10th European Slag Conference will take place in Thessaloniki, Greece on 9 – 11 October 2019. The conference is jointly organised by the Laboratory of Building Materials of the Aristotle University of Thessaloniki, Euroslag and Aeiforos. The title of the Conference is: Slag based products – best practices for Circular Economy. Key topics at the conference will include: legal framework; utilisation and best practices; research and innovation.

Euroslag is the European association of all main organisations and companies concerned with all aspects of manufacturing and utilisation of ferrous slag products. Thessaloniki's main university, Aristotle University (AUTH), is the largest in Greece and in the Balkans. The Laboratory of Building Materials (AUTH) is devoted to research on utilisation of industrial by-products. Aeiforos, part of the Sidenor Group, offers a large range of services in the field of by-product management and valorisation since 2001.

Germany: Loesche says it is continuing its research and development of a process to create a steel slag suitable for cement production following a legal dispute.

The engineering company has worked with the FA Finger-Institut für Baustoffkunde (FIB) at Bauhaus-Universität Weimar on the thermally reductive modification of steel slags for recycling iron and manufacturing ‘steelworks clinker.’ It has developed two procedures for thermally reductive conditioning of BOF (Basic Oxygen Furnace) slag that have been registered for a patent, which largely differ in the respective cooling process for the remaining molten metal. The individual stages of the procedure have already been tried and tested on an industrial scale. Loesche’s partner for the entire procedure is Primetals Technologies based in Linz, Austria, which has industrial-scale plants for reduction and fast cooling based on patented procedures in its product range. The remaining iron (approximately 8 - 10%) that is still in the ‘steelwork clinker’ can then be separated in a Loesche mill. The separation procedure for this, which has also been patented by Loesche, has been in operation for approximately six years to recycle stainless steel from stainless steel slags in a recycling plant in Belgium.

However, following smelting trials conducted with the Bundesanstalt für Materialforschung und -prüfung (BAM) in 2011, Loesche faced a lawsuit regarding the patents for its procedures. The legal uncertainty that this created led to the suspension of further development and implementation of the two procedures for more than three years. The legal dispute was resolved in December 2017. The second conditioning procedure – the fast cooling – was assigned as the sole property of Loesche. A third of the ownership of the first conditioning procedure - slow cooling – was conceded to the BAM, represented by the German government.

Loesche now plans to implement the second procedure into industrial practice.

Germany: Hargreaves Raw Material Services has ordered a coal grinding plant from Claudius Peters. The plant will be installed at DK Recycling und Roheisen’s plant in Duisburg. DK, a recycler of ferrous waste including slag, will also operate the unit. Hargreaves, a raw material trader, plans to use the coal mill to supply clients in Germany and Western Europe.

The scope of supply comprises the raw coal handling, a EM 95 – 6118 type mill with a capacity of 52t/hr, the pneumatic conveying to the (already existing) coal dust silos at a distance of about 500m and four coal dust silos with truck loading. Claudius Peters will be responsible for engineering, delivery, erection and commissioning including staff training. Commissioning is planned for the fourth quarter 2018.

Europe: Tata Steel and ThyssenKrupp have signed a Memorandum of Understanding to create a European steel company by merging their flat steel businesses in Europe and including ThyssenKrupp’s steel mill. The proposed 50:50 joint venture will have its headquarters in Amsterdam and will be able to supply around 21Mt/yr of flat steel products.

“The Tata Group and ThyssenKrupp have a strong heritage in the global steel industry and share similar culture and values. This partnership is a momentous occasion for both partners, who will focus on building a strong European steel enterprise. The strategic logic of the proposed joint venture in Europe is based on very strong fundamentals and I am confident that ThyssenKrupp Tata Steel will have a great future,” said N Chandrasekaran, the chairman of Tata Steel.

The merger will create the region’s second largest steel producer after ArcelorMittal. Cost synergies of up to Euro600m/yr are expected through the integration of commercial functions, research and development and other supporting activities. In addition to this, ThyssenKrupp Tata Steel would seek to improve capacity utilisation of the network across the three hubs of Ijmuiden in the Netherlands, Duisburg in Germany and Port Talbot in the UK and their related downstream facilities.
