US: The United States Geological Survey (USGS) estimates that the US sold 17Mt of ferrous slags in 2021, a rise of 31% year-on-year from the estimate in 2020. Blast furnace slag represented about 49% of the volume sold and accounted for 87% of the total value ofslag, most of which was granulated. Steel slag produced from oxygen and electric arc furnaces accounted forthe remainder of sales. Slag was processed by 28 companies servicing active iron and steel facilities or reprocessing old slag piles at about 124 processing plants, including some iron and steel plants with more than one slag-processing facility, in 33 States, including facilities that import and grind unground slag to sell as ground granulated blast furnace slag (GGBFS).

A further 2.2Mt was imported, a slight decline from 2020. From 2017 to 2020 the USGS reports that 42% of imported slag came from Japan, 18% from Brazil, 11% from China and 10% from Italy.

The USGS noted that during 2021, domestic GGBFS remained in limited supply because granulation cooling was known to be available at only two active US blast furnaces while, elsewhere, only one domestic plant produced pelletised slag in limited supply. Grinding of granulated blast furnace slag was only performed domestically by cement companies. However, following Covid-19 related decrease in availability in 2020, supply of steel slag increased in 2021.

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.

Europe: AcelorMittal has received approval from the European Commission (EC) for the sale of selected steelmaking assets to Liberty House Group. The divestment includes ArcelorMittal Ostrava in the Czech Republic, ArcelorMittal Galati in Romania, ArcelorMittal Skopje in North Macedonia, ArcelorMittal Piombin in Italy, ArcelorMittal Dudelange in Luxembourg and several finishing lines at ArcelorMittal Liège in Belgium. The assets are part of a divestment package that AcelorMittal agreed with the EC during its merger control investigation into its acquisition of Ilva. The transaction is expected to close before the end of the first half of 2019.

Italy: Finland’s Tapojärvi has signed a contract to supply slag handling and metal recovery services at ThyssenKrupp’s Acciai Speciali Terni steel mill. Tapojärvi Italia will build a slag-handling unit and then start to produce and develop slag-based products. The contract consists of two-year period of building the unit and 10 years of operating time with additional option for another 10 years of operations.

“We have innovative and cost efficient solutions to meet the challenges steel mills have around the world. We productise industrial by-products and develop new business opportunities around these materials all the time,” said Mari Pilventö, the chief executive officer (CEO) of Tapojärvi Oy.

Italy/UK: Ametek Land in the UK has collaborated with Italy’s Danieli on its automatic tapping system to increase operation safety and improve process control for steel plants. The Danieli Automatic Electric Arc Furnace (EAF) Tapping System product allows complete furnace tapping remotely from the main pulpit of a steel plant. The system starts furnace tilting in automatic mode, controlling the furnace position during the complete tapping process.

Embedded within the system are two thermal imaging systems from Ametek Land: its Slag Detection System (SDS-E), branded as Danieli’s Q-Slag, and a near-infrared (NIR) fixed thermal imager that is part of the Ladle Level Detection (LLD) system. The thermal imaging systems are used in conjunction with Danieli software to control steel flow in real time.

Q-Slag makes use of an SDS-E imager to detect the transition between steel and slag. It also quantifies the amount of slag that may pass into the ladle. That information is useful for fine-tuning alloys and lime additions for the secondary metallurgy. In parallel with Q-Slag, the LLD system controls when steel inside the teeming ladle has reached pre-set level positions. Back tilting can be done either in automatic mode (when the pre-conditions regarding steel level and weight are met) or by remote intervention of the EAF operator from the main pulpit.

Ametek Land says that its Slag Detection System can improve operator response times and steel consistency at the end of each tap. Those improvements typically result in up to a 25% reduction in slag depths, compared with traditional methods of stream monitoring.

Danieli designs plants and manufactures and installs machines for the metals industry covering the entire production cycle from raw ore to finished steel products. Ametek Land manufactures monitors and analysers for industrial infrared non-contact temperature measurement, combustion efficiency and environmental pollutant emissions.

Italy: Cemitaly has been allowed to use slag and ash in cement production at its Taranto plant following an investigation, according to the Il Fatto Quotidiano newspaper. The former Cementir unit was investigated in 2017 as part of an illegal waste probe that examined whether the Taranto plant purchased ‘illegal’ by-products from Enel and the ILVA steel plant to produce cement.

Italy: Buzzi Unicem has announced that it purchased a 50% stake in Ecotrade in early 2017. Ecotrade supplies industrial byproducts, such as fly ash and blast furnace slags, from power plants and steel mills to the cement industry with deliveries of over 2Mt/yr at its peak. The company is a member of the Italian Register of Environmental Operators and it has a national distribution network in Italy. Buzzi Unicem intends to use Ecotrade’s expertise to expand its operations internally.
