Product Details
High Precision 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.
We supply different models stainless steel cold rolling mills of
high level configuration to stainless steel coil plants, thus
accumulate rich experiences in stainless steel rolling technology,
can ensure high efficiency stable rolling process, customers will
profit from investing cold mill made by our company.
Take 850 four roller (4 high) reversible cold rolling mill for stainless
steel strip up to 750mm with hydraulic AGC configuration as example.

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.
Company Profile
We are metal coil sheet processing machine manufacturer and
supplier, we dedicate to supply of good quality machines and
provision of complete services.
We work in the coil processing machine field for over 20years, we
design and make each machine customized. From machine parts
materials selection, each part machining and treatment, whole
machine assembly and surface painting, we carefully note each
detail of whole production process to achieve good quality machine
result.
Rich Experiences:
Our people witness the developing process of sheet processing
machines and develop ourselves with market, thus able to supply
customers good machines at competitive prices.

Efficient Responses:
Investment of metallurgical equipment is a system engineering,
which requires comprehensive plan and successive execution. The
efficient responses of the equipment suppliers are very important.
We did well in this and cooperate with customers for long time.

Senses of Mission:
Nothing proceeds smoothly without any problem, the important is to
face and solve the problem. We put problem solution in priority,
never escape responsibilities. Supply of good machines creating
profit for customers is our mission, the most profitable equipment
is the best. Customer is the King, we must provide him the most
suitable machine to return his trust.

After-sale Services:
We can send engineers to customer plant to do machine installation
and commissioning; we provide hydraulic schematic drawing, electric
principle diagrams, mechanic spare parts drawings, civil works
drawing; We always listen and give consultation.
