Continuous decarburization and annealing unit for cold-rolled silicon steel (CNGO)

Continuous decarburization and annealing unit for cold-rolled silicon steel (CNGO)

The cold-rolled non-oriented silicon steel (CNGO) is degreased, decarburized and annealed, and recrystallized annealed under a protective atmosphere to reduce the carbon content of the strip to the specified range, to grow the grains, improve the magnetic properties, eliminate stress, and apply an insulating layer.

Stainless steel annealing and pickling unit (CAPL)

Stainless steel annealing and pickling unit (CAPL)

The stainless steel cold-rolled pickling and annealing process can be divided into intermediate annealing pickling and final annealing pickling. The main purpose is to recrystallize the cold-rolled stainless steel after annealing to eliminate work hardening, thereby softening and improving mechanical properties, and to remove impurities such as iron oxide scale generated during annealing through pickling, further improving the surface quality of the strip.

Continuous Annealing Line (CAL)

Continuous Annealing Line (CAL)

Annealing steel strip is to homogenize the chemical composition and structure of the steel, refine the grain size, adjust the hardness, eliminate internal stress and work hardening, and improve the forming processability of the steel. Continuous annealing is a process in which the steel strip is heated to an appropriate temperature under a protective atmosphere and held for a certain period of time, followed by cooling and overaging treatment. In order to improve the surface quality of the strip, an online leveling machine is generally designed.

Continuous color-coated steel production line (PPGI, PPGL)

Continuous color-coated steel production line (PPGI, PPGL)

A continuous roll coating line for steel strip applies a paint film coating to galvanized (aluminum) or aluminum substrates to further improve corrosion resistance and aesthetics, expanding the range of product applications.

Continuous cold-rolled galvanized steel production line (GI)

Continuous cold-rolled galvanized steel production line (GI)

Using cold-rolled steel as a raw material, a layer of zinc or zinc-aluminum alloy is applied to the surface of the strip steel through hot-dip galvanizing, which has strong cathodic protection performance, making it widely used in various fields such as industry, agriculture and construction, and becoming a widely used coated product today.
