What is the roll roll forming machine? (Serial) 3

    Cold-formed steel sections corner portion of the material to plastic deformation occurs due to the bending cold work hardening, which increase strength, ductility decreased, a phenomenon known as cold bending effects. If the effect of the use of cold-formed after improving strength component design, it can save 10% to 15% of the steel, but also as a means to improve the strength of cold-formed steel safety reserves.


    At present, China for the term "Cold Roll Forming" this process is called a variety of names: one is a translation from Russian over, called the roll forming, cold-formed steel (metallurgical industry, multi-use this argument); one is from the English and other foreign language translation over, called "cold roll forming", roll forming, roll forming, roll forming, roll forming, etc; there is a name for China Taiwan, called wheel molding, cold forming and the like; English name of comparison to determine, there is Rollforming, Roll-forming, Roll Forming ;; literal translation from English to Japanese use the way, the cold room's molding sand.

    Since the "roll cold forming" process, the strip is fed by the initiative of forming rolls, and therefore can roll forming and welding, perforation, print, cut to length, wire and cardboard and other involved in a variety of technology combined and become joint continuous production line.
