Germany: Building materials research institute FEhS-Institute says that cement producers used 7.9Mt of German ground granulated blast furnace slag (GGBFS) in cement production in 2022. This corresponds to 71% of the 11.1Mt of slag produced by the domestic iron and steel industries during the year. Other applications for the slag included aggregates production (3.1Mt - 28%) and internal recycling at the refinery (500,000t - 4.5%).

Managing director Thomas Reiche said "Unlike recycled materials, iron mill slags are already high-quality and climate-friendly secondary raw materials in their 'first life.' For decades they have made an important contribution to a sustainable recycling economy in Germany. To ensure that this can continue in the future after the transformation of the steel industry, we have been researching new slags together with our partners since 2013 - for example, with the Direct Reduction Of Iron Ore Electric Furnace Slag and Save CO2 projects to develop Blast Furnace Slag 2.0."

Australia: Australian Steel Mill Services (ASMS) and the University of Wollongong have launched an investigation into the possible industrial uses of steel furnace slag (SFS) at the Steel Research Hub in Wollongong, New South Wales. ASMS says that SFS has historically had a lower recyclability than ground granulated blast furnace slag (GGBFS) because of its behaviour when hydrated, which potentially includes expanding. The research team believes that SFS might be a possible ingredient for construction materials, including paving slabs. Tests will involve mixtures of SFS with cement, lime, lignosulphonate, coal wash and plastics.

US: Harsco’s Environmental division has driven its parent group’s revenue in 2021 as services and product demand increased. Its revenue rose by 17% year-on-year to US$1.07bn in 2021 from US$914m in 2020. Its operating income grew by 75% to US$103m from US$59m. Overall group revenue and operating income increased by 20% to US$1.85bn and from a loss of US$3.3m in 2020 to a profit of US$88.4m respectively.

“For the fourth quarter, our businesses continued to benefit from increased environmental solutions demand, and I'm pleased to have met our expectations for the quarter. However, steel volumes slowed through the fourth quarter in some markets, inflation pressures persisted, and labour-market tightness and Omicron impacted productivity. We were able to offset these pressures by controlling our overall spending in the fourth quarter,” said chairman and chief executive officer Nick Grasberger. He added that the group expects to see further improved operating results from its Environmental division in 2022.

World: World Steel Association data shows that crude steel production grew by 14.4% to 1Bt in the first half of 2021. Production in Africa and South America rebounded the fastest although these areas are amongst the smallest production regions. China produced 563Mt of crude steel in the reporting period, a rise of 11.8%, much more than Africa and South America combined. India, the next biggest manufacturer, produced 57.9Mt, a rise of 31.3%.

Belgium: The World Steel Association says that global steel production in the first half of 2020 was 873Mt, down by 6% year-on-year from 929Mt. Global June 2020 steel production also fell, by 7% year-on-year to 148Mt from 159Mt in June 2019 and by 0.7% month-on-month from 149Mt in May 2020. China produced 91.6Mt in June 2020, up by 4.5% from 87.7Mt, corresponding to 62% of global steel production for the month. The sharpest falls occurred in the US, by 35% to 4.7Mt from 7.2Mt, and in France, by 35% to 800,000t from 1.23Mt.

Belgium: The World Steel Association (WSA) forecasts that total global steel consumption in 2020 will be 1.65Bnt, down by 6.4% year-on-year from 1.77Bnt in 2019, due to the impacts of the coronavirus outbreak on steel-intensive industries. The WSA estimated that demand will decline by 17% in developed countries, with the steepest falls in Japan, South Korea and the US, and by 18% in India. China’s steel consumption is expected to rise by 1% due to increased infrastructure spending and a swift post-coronavirus recovery. Construction, a mostly seasonal sector, had already reached full productivity in April 2020.

The WSA expects steel demand to increase by 3.8% year-on-year in 2021 to 1.72Bnt globally. The sharpest recovery is expected to be in developing countries, where the WSA says that total demand will increase by 9.2%, following a fall of 11.6% in 2020.

World: Data from the World Steel Association shows that global crude steel production fell by 1.4% year-on-year to 443Mt in the first three months of 2020. Asia produced 316Mt of crude steel in the first quarter of 2020, a year-on-year decrease of 0.3%. The European Union (EU) produced 38.3Mt of crude steel in the first quarter of 2020, down by 10%. North America’s crude steel production fell by 4% to 29.5Mt.

India: JSW Cement has revised its planned expansion to its 14Mt/yr total installed capacity to 39Mt/yr before 1 January 2023, an increase of 5Mt/yr compared to its initial target of 34Mt/yr by 2020. The figure includes JSW’s 54% subsidiary Shiva Cement’s new 1Mt/yr integrated and 1Mt/yr grinding plant, valued at a total of US$112m. Parth Jindal, JSW Cement managing director, said that the figure had been revised upward because Shiva Cement had become self-sufficient in clinker production, freeing the group’s east Indian cement production from ‘volatile import costs.’

Economic Times has reported that Shiva Cement is set to bring its limestone reserves to 100Mt with the acquisition of the Khatkurbahal mine. The company sources its granulated blast furnace slag from the Odisha steel industry. Production of JSW Cement’s flagship product, JSW Portland Slag Cement (PSC), releases CO2 at a rate of 325kg/Mt compared to between 760kg/Mt and 800kg/Mt for typical Ordinary Portland Cement (OPC).

Turkey: Erdemir Group has ordered new INBA slag granulations systems as part of an order for two new blast furnaces (BF) from Luxembourg’s Paul Wurth for its Ereğli and Iskenderun integrated steel plants. At both sites a new furnace will replace an older production unit. The new blast furnaces are scheduled for blow-in in March 2021 and May 2021 respectively. No value for the order has been disclosed.

At Ereğli Erdemir’s new BF2 will have a hearth diameter of 10m, 24 tuyeres and two tapholes. It will produce 5000t/day of hot metal from an inner volume of 2188m³. At Isdemir the new BF1 will be sized at 12.5m in the hearth and 3587m³ of inner volume; it will be fitted with 32 tuyeres and four tapholes and will produce 7900t/day, which further increases the hot metal capacity at this site.

Paul Wurth will execute both projects on an EP basis including the supply of technological key items and related supervision of erection and commissioning. The orders include basic engineering of the blast furnaces with profile, cooling and lining concepts as well as the design of the stockhouses, top gas cleaning plants, slag granulation plants and BF cooling units.

For both furnaces, Paul Wurth will supply Bell Less Top charging systems and bleeder valves, refractories for the hot blast mains and bustle pipes, tuyere stocks with tuyere phenomena detection system (TPDS), technological and critical items for the top gas cleaning plants (consisting of axial cyclones, annular gap scrubbers) as well as for in total three INBA slag granulations systems. Extensive sets of TMT probes and process recorders include, inter alia, 3D TopScanburden surface profile meters and SOMA acoustic top gas temperature measurement. Under the same contracts, TMT will also supply fully hydraulic taphole machinery for equipping all the six tapholes in total.

World: Global steel production rose by 4.6% year-on-year to 1.81Bnt in 2018 from 1.73Bnt in 2017. Data from the World Steel Association shows that production rose fastest in the Middle East, Africa and Australasia. Asian production rose by 5.6% to 1.27Bnt and North American production grew by 4.1% to 121Mt. European production remained static at 312Mt, with a slight dip in the European Union (EU) balanced by slight growth in the Commonwealth of Independent States (CIS). China remained the largest steel producing country, with 9.28Mt in 2018. It was followed by India, Japan, the US and South Korea.
