Product Details
Model Name: High Precision 4high 6high Reversible Stainless Steel Cold Rolling Mill Machine
Stainless steel coil strips thickness reducing mill has some unique features:
Stronger Rolling Mill stands, bigger rollers
Much bigger motors to supply bigger rolling force,
Dismantable solid coiling mandrel for convenient intermediate annealing treatment
Automatic hydraulic AGC control system
Usually reversible cold mill
more frequently see reversible SS strip cold rolling mill for the reasons that: stainless steel strip reducing degree can not be as much as normal carbon steel, tandem stainless steel mills will be very costly.
Intermediate annealing for SS strip is solution treatment in continuous annealing furnace at speed of around 40m per minute, after cold rolling and annealing, the tension leveling is also considered in the process.

Work process:
15T Uncoiler, pinch feeder and 5 roller straightener, 1st Recoiler, 4 Hi Hydraulic AGC Reversible Mill, 2nd Recoiler.
Stainless steel strip continuous solution annealing furnace line.
Uncoiler with 22KW motor for threading, in normal production, is passive uncoiling with brake
Heat temperature about 1070°C under protection air atmosphere.
Heating furnace is composed of pre heating zone and hot heating zone, total about 25m length
S roll briddle unit at exit of furnace to pull stainless steel strip continuously out from furnace
Two recoilers, one is working and the other is discharging annealed SS coil and ready for next coil recoiling, to ensure non stop continuous working of the whole annealing line.
