What is Cold rolled?
Cold rolled is usually performed by longitudinal rolling. The process of cold
rolling production generally includes raw material preparation,
pickling, rolling, degreasing, annealing (heat treatment),
finishing and so on. Cold rolling uses hot rolled products as raw
materials, and the raw materials must be dephosphorized before cold
rolling to ensure the surface of the cold rolled products is clean.
Rolling is the main process of deforming the material. The purpose
of degreasing is to remove the lubricating grease attached to the
rolling material during rolling, so as not to contaminate the
surface of the steel during annealing, and to prevent carbon
addition to stainless steel. Annealing includes intermediate
annealing and heat treatment of the finished product. The
intermediate annealing is to eliminate the work hardening caused by
cold deformation through recrystallization to restore the
plasticity of the material and reduce the deformation resistance of
the metal. The purpose of the heat treatment of the finished
product is to eliminate hardening by recrystallization. It is also
based on the technical requirements of the product to obtain the
required organization (such as various textures, etc.) and product
performance (such as deep drawing, electromagnetic performance,
etc.). Finishing includes inspection, cutting, straightening
(flattening), printing, sorting and packaging. Cold rolled products
have high packaging requirements to prevent the surface of the
product from being scratched during transportation.
