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 emission 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.
The two reheating furnaces will operate on natural gas and will be equipped with wide flame burners and a combustion system with individual on-off control. The wide flame burners improve the crosswise and lengthways temperature profiles of the products, while the individual on-off control allows high thermal efficiency while reducing fuel consumption and NOx emissions.
