In October 2021, Indian steel producer JSW Steel Ltd. started up two continuous slab casters at its Dolvi plant in Maharashtra. Together, the two two-strand casters have an initial annual capacity of around 4.5 million metric tons of slabs with future capacity potential for 6 million metric tons. A number of technology packages ensure that the slabs have high internal and surface quality. Primetals Technologies supplies also a hot rolling mill to the new Dolvi expansion plant. The hot rolling mill has an annual capacity of 5 million metric tons per year. JSW Steel already operates three continuous casting plants from Primetals Technologies at its steel works in Toranagallu, Karnataka.

In early November, a KOBM converter, upgraded from a former BOF converter by Primetals Technologies, was started up in the steel plant of HBIS Group Handan Iron and Steel in Handan, China. Compared to a BOF converter, the combined blowing from top and bottom in a KOBM converter results in a better bath mixing and metallurgical reactions are closer to the equilibrium. In addition, lime injection ensures fast slag formation and excellent process and slopping control. Therefore, this process is expected to shorten the blowing process, to lower the carbon-oxygen equilibrium of the steel at tapping, improve the yield by lowering slag amount and iron oxide content in the slag, and to produce cleaner steel with minimum inclusions and impurities. The improved steel quality especially fits requirements from the automotive industry. Furthermore, the new converter has the potential to save ladle additions during tapping as well as costs for lime additions.

In November 2021, Chinese steel producer Wuzhou Yongda Iron and Steel Co., Ltd. (Wuzhou Yongda) issued the final acceptance certificate (FAC) for an EAF Quantum electric arc furnace and twin ladle furnace supplied by Primetals Technologies for a greenfield project in Wuzhou city, in Guangxi Zhuang Autonomous Region. The EAF Quantum furnace is designed to handle scrap steel of very varied composition and quality. The electrical energy requirement of the electric arc furnace is extremely low because the scrap is preheated. This reduces both the operating costs and the CO₂ emissions. The twin ladle furnace sets the desired steel grades and the correct casting temperature.

Recently, Chinese steel producer Henan Yaxin Steel Group Co., Ltd. (Henan Yaxin) has started up its eco-friendly minimill for flat products consisting of two EAF Quantum electric arc furnaces and an Arvedi ESP line at its Fujian Dingsheng plant. Tapping weight of each EAF unit is maximum 115 metric tons. This set-up allows for 85% CO₂ savings compared to integrated production route. The Arvedi ESP line has a design capacity of 2.5 million metric tons per year and a reproducible strip thicknesses down to 0.8 mm. This enables Henan Yaxin to produce high-quality, ultra-thin strip to enter new market segments with direct application products omitting cold rolling. Coils for the sales market were directly produced during first heat.

In September, Primetals Technologies received an order from Aperam Genk in Belgium to supply a new argon oxygen decarburization (AOD) production line and to upgrade the existing AOD 1 production line. The objectives of the project are to increase operational safety, to improve operating costs, and to further reduce environmental impacts via a dedusting system with provisions for heat recovery. Primetals Technologies will be responsible for mechanical equipment, electrics and automation as well as auxiliary equipment. The project will be carried out in a consortium with Austrian erection company SGS Industrial Services. Start-up is expected for mid-2023.
