Russia: Sibirsky Cement Holding (Sibtsem) subsidiary Topkinsky Cement has announced that it has entered commercial production of a new Mita slag Portland cement with granulated blast furnace slag (GBFS) at its 2.7Mt/yr integrated plant in Topki, for which it received a certification of conformity with ‘cement for general construction’ standards on 16 January 2020. Nina Poputnikova, Topkinsky Cement laboratory and quality department head, said that it is producing the cement in response to ‘construction companies’ increased interest in cement for use in reinforced, precast concrete in monolithic structures such as buried and hydraulic structures.’

“In the near future we plan to certify two new cements,” said Topkinsky Cement managing director Alexey Ospelnikov. One will be a low-heat general-purpose cement for large-sized concrete structures and the other a sulphate-resistant Portland cement. “Expanding the assortment will help strengthen the company’s position in the Russian cement market.”

Brazil: Itaci Cement has purchased 100ha of land in Tabuleiro do Norte in the north-eastern Brazilian state of Ceará. Diario do Nordeste has reported that the company has invested US$66m in a development, though whether this will take the form of a clinker grinding or integrated cement plant has not been disclosed.
Companhia Siderúrgica do Pecém (CSP) will reportedly supply granulated blast furnace slag to the facility when operational for use as a feedstock.

US: Shawn M Garvin, secretary of the Department of Natural Resources and Environmental Control (DNREC), has issued a Secretary’s Order granting an air quality construction permit for Walan Specialty Construction Products to build a slag grinding plant at Wilmington in Delaware. Walan, also known locally as Penn Mag, is required to use best available control technology (BACT) to control particulate emissions from the drying and grinding operations and to limit truck activity at the site to paved surfaces. The permit has approved a throughput limit of 150,000t/yr of slag, a reduction of 43% compared to the original application.

UK: Fairport Engineering has revealed details on its work on Hanson’s 1Mt/yr Purfleet ground granulated blast furnace slag (GGBS) grinding plant. The plant includes two closed circuit ball mills and a vertical roller mill. Fairport Engineering worked on a project to improve the raw material intake facilities at the unit to replace a storage bunker with a new feed hopper and ramp. In the next phase the bunker is likely to be removed and replaced with a second feeding system.

The new system includes a reinforced concrete access ramp that will allow front-end loaders to deposit raw material into a 30t capacity Hardox lined hopper before being metered, at up to 200t/hr, by a vibrating feeder, onto an exiting conveyor belt that feeds the GGBS plant. The entire installation was completed in six weeks.

Netherlands: Ecocem Benelux has inaugurated a new 5000t export silo at its Moerdijk ground granulated blastfurnace slag (GGBS) plant. The new silo has been built at the waterfront in Moerdijk and rests on 65 piles sunk to a depth of up to 50m. The system operates via a screw extractor that conveys the GGBS to the centre of the bulk silo, where screws and a bucket elevator carry it to the new 150m³ day-silo. Both trucks and ships can be directly loaded from the silo: trucks on the weighing bridge situated under the silo and ships via a pneumatic transport installation with a maximum capacity of 250t/hr.

Ecocem Benelux is a subsidiary of Ireland’s Ecocem Materials. Ecocem Benelux supplies GGBS in bulk to the Belgium, Netherlands and Luxembourg (Benelux) market for both concrete and mortars. The facility also exports to the Swedish market. Since opening in 2002 the plant has doubled its production capacity to 0.65Mt/yr.

Kazakhstan: Technogran Aktobe plans to build a cast iron plant in Mangistau region at a cost of US$200m. The plant will produce 250,000t/yr of cast iron and 250,000t/yr of granulated slag, according to Interfax. Slag from the plant will be used for cement production and road construction. These products will be exported to Turkmenistan, Kyrgyzstan and Uzbekistan.

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.

UAE: Emirates Steel has signed a deal with Finland’s Ecofer for slag management services for 10 years from 2020. Ecofer will process slag from Emirates Steel's Abu Dhabi plant and sell it to the construction industry, according to the Khaleej Times newspaper. The steel producer has been recycling its Electric Arc Furnace (EAF) slag product since 2014, producing roughly 2.8Mt of EAF slag in this period.

"As one of the largest integrated manufacturers of finished steel products in the region, we produce 0.8Mt/yr of slag and we are committed to finding ways to mitigate our impact on the environment,” said Saeed Ghumran Al Remeithi, the chief executive officer (CEO) of Emirates Steel.

Ecofer arranged an agreement with Egypt’s Ezz Steel earlier in 2019. The latest deal with Emirates Steel continues its intent to build strategic partnerships in the Middle East.

US: Councillors at the Vallejo City Council in California are preparing to make a decision on Orcem Americas’ slag cement plant project at the end of May 2019. The council has released a new draft Final Environmental Impact Report (FEIR), according to the Vallejo Times-Herald newspaper. However, staff said the document is not ready to be presented to the council for certification and possible project approval under the California Environmental Quality Act (CEQA) due to a lack of information and cooperation from the applicants for the draft status of the report. Planning permission for the slag grinding plant and marine terminal was refused in early 2017.

India: JSW Steel has signed a 10-year agreement with US-based Harsco for a range of mill services. Harsco will provide JSW Dolvi in Maharashtra with on-site slag handling services including under-furnace digging, ladle wrecking, and hot slag transport. No value for the contract has been disclosed.
