1. The specification of the rolling production (mm):0.7mm stainless steel
2. The speed of the roll-in: 10-12M/min
3. The number of the roller: about 18 stations
4. The material of the roller: use the excellent hammered steel GCr15 to be quenched as a whole, then to process by numerical control.
5. The material of the principal axis: use the excellent steel No.45 to process.
6. The power of the principal electric motor: 7.5kW
7. Hydrodynamic station cut: 5.5kW

It is the practice in the steel industry that structural shapes are assigned representative designations for convenient shorthand description on drawings and documentation: Channel sections, with or without flange stiffeners, are usually referenced as C shapes; Channel sections without flange stiffeners are also referenced as U shapes; Point symmetric sections that are shaped similar to the letter Z are referenced as Z shapes. Section designations can be regional and even specific to a manufacturer. In steel building construction, secondary members such as purlins (roof) and girts (wall) are frequently cold-formed steel C, Z or U sections, (or mill rolled) C sections.
