Product Details
High Precision Hydraulic AGC Cold Rolling Mill Machine Reversible
or Tandem
Hydraulic AGC rolling mill is becoming more and more popular in
metal strip rolling industry for its high precision, high speed and
high automation
Screw down of Rolling Mill has options of mechanic type and hydraulic AGC type,
- mechanic type is composed of motor,speed reducer,brake,worm screw, spherical
pad,etc. upper roll can be adjusted quickly and frequently with
large stroke and without rolling load, simpler structure and easier
maintenance, complex transmission system and lower sensitivity, not
suitable for high speed high precision rolling.
- Hydraulic screwdown is composed of hydraulic cylinder, servo
valves, hydraulic system, as well as checking meters and computing
control system, which don't have complex transmission structure.
Hydraulic press down or up system cold rolling mill Characters:
- Hydraulic AGC press-up system with automatic control, including
hydraulic press-up cylinders, AGC control system, hydraulic
station, thickness gauges, with functions of constant roller
clearance position control, constant pressure control and automatic
tilt adjusting control.
- CPU computer automatic control system
- HIM touch screen for dynamic display, rolling parameters setting,
breakdown alarms and report printing.
- Digital DC or frequency AC drive
- Drive middle rollers (separately drive upper middle roller and
lower middle roller.
- rollers cooling control divided in five zones , emusified water
flow control
- work roller positive/negative bending control
- Presetting of middle roller transfer and middle roller positive
bending control
- zero setting of rolling centerline by wedge.
- work rollers and middle rollers fast changing equipment
- automatic adjustment of rolling speed and tension
- Protection measures in case of strip break, accidents alarms and
emergency stop.
- oil gas lubrication for work rollers, middle rollers and backup
rollers.
- Roller bearings for backup rollers
- X-ray thickness gauge
- Rolling process linkage and defect alarms controlled by PLC
- The presetting of rolling process, the inspection, display and
alarm of rolling process parameters and critical machine parameters

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.
