Tandem 4 High Cold Rolling Mill Line With Spiral Accumulator ( 700
)
Spiral accumulator in tandem cold rolling mill line accumulates 2
or 3 coils in loop to ensure the tandem mill line continuously
work. The continuous rolling output large scale cold rolled coils
production. The tandem cold rmill line with accumulator specially
suit plain carbon steel coil cold rolling.
Plain carbon steel coil processing plant witness tandem cold
rolling mill who continuously reduce steel plate thickness at
hundreds of meters per minute, the tandem rolling mill can give
multiple production.
The competition of the tandem mill is continuous rolling: one way
from uncoiling to coiling and working without stop, so, automatic
shear and welding machine, strip accumulator and double recoilers
are on the rolling line.
Automatic shear & welding and spiral accumulator keep uncoiling
and strip feeding continuous, double coilers are good way to keep
continuous coiling. These characters of tandem rolling machine make
automation and production go to huge scale.
Tandem cold mill requires:
- Huge power supply and consumption, high efficiency cold mill can
save power and control rolling process cost.
- Emulsified water for rolling process cooling needs a big pool with
filtering system to keep enough clean coolant.
- Electrc control cabinets and panels are high precision programming
and reaction system to ensure high speed precision rolling.
- Tension cell synchronize the rolling speed and tension between two
mills.
- Operator must be skilled to run the mill
- Thickness gauges are necessary to control sheet gauge.
- Thin oil lubricating system for gearboxes of mill and recoiler.
For non pickled black Hot Rolled mild steel strip cold rolling, two
heads tandem mill is popular, because it reduces thickness two
passes continuously to reach the required 50 -60% gauge reduction.
The rolling process includes uncoiler, shear welder, accumulator,
two heads mill and recoiler. hydraulic system, electric control
system, lubricating system are the indispensible conditions for the
tandem cold mill smooth running.
