ISO 6 High Reversible Cold Rolling Mill
1. Introduction:
6-Hi Reversing Cold Rolling Mill
Due to different numbers of rollers, the metal coil cold rolling mill is divided into 2 Hi, 4 Hi, 6 Hi, and 12 Hi AGC.
The six-high cold rolling mill is more suitable for carbon steel, stainless steel and special steel coil rolling; even the steel with large width and small finished thickness is available too.
2. Characteristics:
- The good flatness of steel strip is controlled by hydraulic roller bending device and middle roller transfer device control.
- Due to the smaller flat work rollers, the roller material can be saved, so that the roller consumption can be also reduced.
- The thickness can be reduced by each pass.
3. Work flow:
Decoiler with coil loading car → Coil end straightener → Left recoiler with coil discharging car → Work platform before rolling mill → 6-hi cold rolling mill → Work platform after rolling mill → Right recoiler with coil discharging car
Because of the different input thickness, input width and finished thickness, six-high cold rolling mill can be divided into 2 types.
4. Technical Parameters:
- Thickness tolerance: ±0.02mm
- Running speed: 4m/s
- Total installation power: about 2200KW
- Occupation: about 15mX60m
5. Characteristics:
- This kind of cold rolling mill is controlled by PLC.
- It has HIM touch screen on main control console which is equipped with malfunction alarm setting.
- This equipment adopts all digital DC power.
- The work rollers have the plus-minus roller-bending control.
- These middle rollers, middle rollers and backup rollers change fast.
- The reversible rolling on this cold rolling mill has the feature of high precison.
