Usually, we call strip when the stainless steel roll width is below 600mm, call coil when the roll width is above 600mm, but sometimes people don’t care about the different more.
The strip is further processing from coil and ready to make smaller parts by cutting, stamping, bending, welding, drilling etc.. all kinds of mechanical processing
A simple description of the normal cold rolled stainless steel slitting system:
The production line has the main functions of unwinding, leveling, slitting, tensioning and rolling. Slitting main equipment include feeding car, uncoiler, leveling machine and power, front looper, slitting machine and power, scrap collecter machine, after the looper, tension machines, recoiler, auxiliary support, unloading devices, hydraulic systems, electrical systems and other components.
The whole production slitting system adopts PLC centralized control. About the man-machine interface display, It is an electronic control system that supply by such as Mitsubishi, Yaskawa, Siemens, Baumuller, Delta, and Schneider. All the controlling data can be set according to the order quantity, Different specifications, slitting speed and other parameters freely, this kind system with the promotion of efficiency, reduce costs, long service life, and stability characteristics.
The stainless steel strip width, wave, flatness, edge smooth, can be controlled well by suitable setting from the slitting system PLC controller.
In China, several years ago, most the stainless steel strip slitting machines be imported from other countries such as Germany, Japan, Italy. Now this machine can be produced in China directly and the slitting tolerance and precision also very good, and start to export to other countries.
