The cold rolling process for steel strap

The cold rolling process for steel strap. The process of cold rolling production of steel strap mainly includes raw material preparation, pickling, rolling, degreasing, annealing (heat treatment), finishing and so on. Cold rolling need hot rolling products as raw materials, and the raw materials should be descaled before cold rolling to ensure the surface cleanliness of cold rolling products. Rolling is the main process of material deformation. The purpose of degreasing is to remove the lubricating grease attached to the rolling material during rolling, so as to avoid contamination of steel surface during annealing, contamination of steel surface during annealing, and to prevent carbonation of stainless steel. Annealing includes intermediate annealing and heat treatment of finished products. Intermediate annealing is the work hardening produced by recrystallization to restore the plasticity of materials and reduce the deformation resistance of metals. The purpose of heat treatment of finished products is to eliminate hardening by recrystallization. It also depends on the technical requirements of the product to obtain the required microstructure (such as various textures) and product properties (such as deep impulse, electromagnetic properties, etc). Finishing includes inspection, shearing, straightening (leveling), printing, sorting packaging and so on.
