Chinese steel producer Henan Yaxin Steel Group Co Ltd has recently 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 tonnes. 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 tonnes per year of 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.The given maturity level of Arvedi ESP technology allowed coil production right from the first heat. Thirteen coils have been produced in endless operation during start of hot commissioning by first heat. The plant operated in stable endless operation and hot rolled ultra-thin direct application material. These products allow Henan Yaxin to better serve the highly attractive local and export markets for high-quality, thin-gauge strip products.This is the first environmentally friendly minimill installation worldwide where EAF Quantum and Arvedi ESP are combined. The extremely low requirement of electrical energy of this minimill for flat products contributes to a reduction of CO2 emissions as well as reduction of operating costs. The new EAF Quantum expedites a transition of the existing production to a more environmentally compatible electric steelmaking process. The Arvedi ESP process uses the heat of the cast strand for the first rolling step. An induction heater supports the second rolling step with minimum electrical energy and ESP rolls with zero direct emissions.The privately-owned concern Henan Yaxin operates integrated and compact steelmaking plants in five provinces and cities in China, and can produce more than ten million metric tons of steel each year. Primetals Technologies supplied the entire mechanical and electrical process equipment for both new EAF Quantum electric arc furnaces and the Arvedi ESP line. “Balance of plant” equipment and services have been provided by a local design institute.
