The Continuous Annealing Line is a unique solution that enables
large-scale production of the highest strip quality in respect of
the most difficult steel grades to be annealed. We offer the best
technologies for furnace, line equipment, and automation, and our
extensive process expertise allows us to meet the expectations of
our clients. These solutions are reliable and optimized in terms of
operation and maintenance costs.
Main benefits Numerous references and many years of experience
Internal solutions for Mechanical, Furnace, Automation, and
In-house mechatronic machines
Flexibility to produce the most advanced steel grades in the
industry
High efficiency, radiant tube furnace utilizing accurate
temperature control with advanced thermal models
The system enables higher temperature thermal cycles, reduces
radiant tube furnace load, and eases transition control
Patented high hydrogen, rapid cooling achieves utilizing
patent-pending to ensuring uniform temperature profile across the
strip width
Annealing treatment is one of the important procedures during steel
strip cold rolling production procedure. The annealing is purposed
to remove the inner rolling stress of steel strips, improve
mechanical property and clean the surface of steel strips.
Annealing equipments can be categorized into bell type annealing
furnace and continuous annealing furnace. Our company usually
undertakes continuous annealing furnace projects.
