Fives has been selected for two strategical contracts to design and supply reheating furnaces to Chinese steelmakers, both with very strict requirements on energy consumption and NOx emissions.

In China, local steelmakers are committed to choosing green technologies for non-polluting performance.

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, a subsidiary of Walsin Lihwa, a world leading manufacturer of stainless steel. The advanced technology offered by Fives – Stein Reheating walking beam furnace – will completely satisfy Walsin's requirements, claims Fives. The furnace in question will have a capacity of 85 tons/hr and will be equipped with the latest generation AdvanTek burners, designed in France with the sole intention of guaranteeing energy efficiency and ultra-low NOx emissions – less than 100 mg/m3.

The second contract was signed with HBIS SHISTEEL – Shijiazhuang Iron & Steel Company within China’s HBIS Group – for two reheating furnaces, each with a production capacity of 130 tons/hr. According to Fives, the company chose the Stein Digit@l Furnace walking beam furnace because of its green performance. The furnace operates on natural gas, is equipped with Fives' patented wide flame burners and a combustion system with individual on/off control. The wide flame burners are claimed to 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.

HBIS SHISTEEL is relocating its steelmaking facilities 80km from Shijiazhuang city to set up new standards for cleaner, more flexible and more efficient steelmaking in China.

The scope of both projects on an EPC basis includes engineering, equipment supply, erection and commissioning, which will be carried out by Fives Stein Metallurgical Technology (Shanghai), a Fives’ subsidiary in China.
