Fives received an order from China’s Shougang Jingtang United Iron & Steel to design and supply a new galvanizing furnace and inductors dedicated to the production of ultrahigh-strength steels. The Stein Digiflex furnace will be equipped with a FlashCooling system operating at 75% of hydrogen in order to reach optimal cooling performance. In addition, the system offers operational flexibility in terms of cooling rate and temperature cycle control. Fives has also engineered a selective oxidation system to accurately control the oxidation process.

Shougang Jingtang United Iron & Steel will operate six Fives’ furnaces at its Caofeidian facility. The plant’s continuous galvanizing line offers 360,000 tons of annual production. Ultrahigh-strength steels are complex materials, with carefully selected chemical compositions and multiphase microstructures resulting from precisely controlled heating and cooling processes.
