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.
Continuous Annealing Furnace Features
