Celsa Group, a manufacturer of steel long products, fired an ultra-low-emission reheating furnace for new wire-rod rolling mill in the Celsa France complex. The reheating furnace, built and supplied by Fives, has a capacity of 120 metric tons per hour and is designed to charge hot billets of different sections and lengths directly from the caster at 1472°F (800°C). The final products, wire rods and bars, will serve the region’s construction market. The furnace includes complete digital on/off control and heat curve control for optimum combustion with the billet discharge surface temperature at 2138°F (1170°C).
Tenova Italimpianti received a contract for a 340-ton/hour walking-beam furnace from Jindal United Steel Limited (JUSL), a company that specializes in hot and cold rolling of stainless steels, in Jajpur, Odisha, India. The furnace is designed to charge stainless steel (grade series 200, 300 and 400) and low-carbon steel in order to comply with JUSL’s various production needs. The installed combustion system is designed to optimize performance (flame characteristics, efficiency and pollutant emissions) in function of the fuel and burner location (frontal, lateral or radiant application). The multi-level automation control system optimizes heating practices, regulating fuel consumption and scale production.
Tenova successfully started up two 400-ton/hour walking-beam furnaces at Ternium’s new hot-strip mill in Pesqueria, Mexico. The furnaces are designed to heat steel slabs (up to 39 tons) at 2282°F (1250°C) while keeping NOx emissions lower than 60 ppm. This emissions level is well below the required limit. According to Ternium, the furnaces will produce coils to be used in the North American automotive market.
Thyssenkrupp Steel Europe AG awarded Danieli Centro Combustion an order to supply two walking-beam furnaces for steel slabs for its Bruckhausen hot-rolling mill in Duisburg, Germany. The furnaces will achieve high production while reducing energy consumption and NOx emissions. They will also improve slab surface quality. They have a capacity of 380 tph with cold charging and up to 560 tph with hot charging. Start-up of the slab-reheating furnaces is scheduled for the beginning of 2024.
Tenova received a major order for the supply of a walking-beam furnace from thyssenkrupp Steel Europe AG. Designed for the heating of slabs made of alloyed an unalloyed steel, the furnace will be located at the thyssenkrupp’s Beeckerwerth plant in Duisburg, Germany. With a capacity of 380 tons/hour, it will be integrated into the existing hot-rolling mill. The furnace includes a combustion air preheating system to significantly reduce energy consumption. Thanks to the use of low-NOx-emission burners, it will help thyssenkrupp achieve its climate-related emissions targets. Start-up is scheduled for July 2022.
Thyssenkrupp will add a new walking-beam furnace in Hot Strip Mill 2 in the Beeckerwerth plant at its Duisburg, Germany, location. The furnace will ensure improved surface quality of premium sheets used for exterior car body shells. Completion is scheduled for 2022. The walking-beam furnace, which will be over 50 meters long, ensures that surface defects are prevented during the reheating and rolling of slabs. This is achieved by special lifting and lowering devices that prevent damage to the surfaces of the slabs, which weigh up to 30 metric tons. Before the new furnace is built, the old unit will be dismantled.
Fives received an order from CELSA Group, a manufacturer of steel long products based in Spain, for a walking-beam furnace. The furnace, which has a capacity of 120 tons per hour, will reheat billets of different sections and lengths to serve a new rolling mill that specializes in the production of steel billets from the recovery of scrap. The furnace includes complete digital on/off control and heat-curve control for optimum combustion. It will be installed in the CELSA France plant located in the municipalities of Boucau and Tarnos, New Aquitaine region. Commissioning is scheduled in the fall.
Fives received an order from JSW Steel, India’s leading steel producer, for an upgrade project of its reheating furnaces at JSW Steel Vijayanagar Works, which currently produces 12 million tons per year. Fives will modernize two reheating furnaces to increase their efficiency and capacity from 250 tons per hour to 295 tons per hour to meet the new requirements of the hot-strip mill N1. Both walking-beam furnaces were previously supplied by Fives. The project for both furnaces is scheduled to be completed by 2021.
Fives received two contracts to design and supply reheating furnaces to Chinese steelmakers, both with strict requirements on energy consumption and NOx emissions. The first project covers an ultra-low-NOx furnace to reheat long products, such as stainless steel bars, coils or wires, for Yantai Walsin Stainless Steel. Fives will supply a walking-beam furnace with a capacity of 85 tons per hour. The second contract was signed with Shijiazhuang Iron & Steel Company within China’s HBIS Group for two reheating furnaces, each with a production capacity of 130 tons per hour.
Nucor Steel Marion Inc. of Marion, Ohio, granted SMS group the final acceptance certificate for the supplied walking-beam furnace after successful commissioning. The furnace, which went into service in the existing bar mill, is capable of delivering 120 short tons per hour of hot billets at 2255°F (1235°C). The NOx content of this furnace is close to 25 parts per million, making it the most energy-efficient furnace with the lowest emission values within Nucor.
