Fives’ furnaces at Baosteel’s Zhanjiang steel plant

The Zhanjiang integrated steel production complex in southeastern China's Guangdong province was officially opened in August by Baosteel, China’s largest manufacturer of automotive steel. 

The Zhanjiang complex consists of a 1,550mm wide cold rolling mill with a pickling line, a pickling line-tandem mill, a continuous annealing line (CAL), a continuous hot-dip galvanising line (CGL) and two silicon steel lines.

The plant has an output capacity is 2.55Mt/yr of high quality coils, mainly for home appliance, general machinery and automotive applications and oriented for the highly demanding Asian market.

Fives, a strategic partner of Baosteel, has designed and supplied two annealing line furnaces and a galvanising line furnace for the plant.

Stein Digiflex furnaces are being employed for A 700kt/yr continuous annealing line and a 270kt/yr galvanising line for a 1,550mm wide cold rolling mill are fed by Stein Digiflex furnaces.

The continuous galvanising line was operational 165 days ahead of schedule, while the annealing line was advanced by 90 days and the cold rolling mill was also implemented ahead of schedule, says Fives.

Stein Digiflex furnaces feature a new compact design and advanced combustion and cooling technologies, including the latest generation AdvantTek WRT 2.0 combustion system. “Such combustion technology benefits from high recuperative energy efficiency, low NOx emissions and usage of site-generated fuels,” claims Fives.

Fives has been providing technology in the field of high-quality strip processing lines and furnaces for advanced automotive and other high value-added steels to Baosteel for more than 25 years. Over the last 10 years, Fives has designed and supplied Baosteel with 13 strip processing lines and furnaces.
