Advanced technology for demanding electrical steel

Heating and cooling innovations
Shougang built a new annealing and pickling line (APL) to produce high-grade, non-grain oriented (NGO) electrical steel for the booming e-vehicle market. The new line required thermal technology that could keep up with its high capacity of 650,000 tonnes per year, which is much greater than a traditional APL.
Fives designed and supplied an annealing furnace that featured advanced heating technology and a flexible cooling system to meet the challenging thermal requirements for high quality electrical steel:
- Dedicated models specifically designed for electrical steel to achieve metallurgical control.
- Enhanced oxygen control for high product quality.
- High temperature thermal technology and heat recovery system to lower operational costs.
- Efficient thermal equipment combined with an emission reduction system.
The engineering and manufacturing of the main equipment were provided from China, while the burners, automation, and process instrumentation were delivered from France.
