1. The AC transmission system uses a fully digital variable frequency speed control device; commonly used are the Siemens S120 series, MM440 series, Huichuan MD380 series, etc.;
2. Equipped with HMI human-machine interface (touch screen), commonly used are Siemens TP270 and MP370 series;
3. Equipped with a host monitoring computer (industrial computer), commonly used are Advantech series, Siemens PC847, etc.;
The rolling force is relatively small. Due to the relatively low hardness of aluminum, the rolling force required in the Cold Rolling process is smaller than that of metals with higher hardness such as rolled steel. This makes the Aluminium Rolling Cold Mill Machinery load of the Aluminum Cold Rolling Mill relatively small, the strength and rigidity requirements of the Aluminum Cold Foil Rolling Mill are relatively low, and the operating cost and maintenance costs of the Cold Rolling Aluminium are also relatively low. It is also conducive to extending the service life of the equipment.
