Paper Machine Super Calender
The super soft calender is the new generation most advanced calender in recent years.
12-roller super calender
12-roller super calender is mainly used for paper industry finishing,one kind of soft calenders.By the effect of high pressure and heat,paper become smooth,plat,lucidus,tight and get transparency.In addition,it can provent form linting and dusting,improving the surface quality.
1.unique roller heating construction and advanced temperature controlling technology,can get unform heat effect.
2.the main rollers use middle-high pressure controlable technology,the linear pressure is adjustable.
3.easily seperate the rolers from the calender and fall to the ground safely.
4.paper tension controlling equipment,paper surface roughness,glossiness and thickness detector.
5.the running speed is steady and adjustable.
Trimed Sheet Width

multi-zone controllable crown roll
Thermal Roll: shell material
alloy chilled cast iron
surface temp variation±1ºC
roll cover is imported, done by special manufacturers
Calendering roll loading and releasing style
bottom tank loading,and releasing
The loading oil tank is controlled by PLC
Quick releasing and slow releasing
Calendering roll quick releasing time ≤0.5s
Calendering roll weight hydraulic compensating system
hydraulic entire or sectional compensation
Thermal roll heating system
Electrical heating, body temp linear control
The heads of soft roll is cooled by blowing
Paper release type( off-line)
Constant tension control motor brake to release paper
Under emergency stop, motors generate electricity to brake
Max unreel tension: 0.7~1.5N/mm
Reel change flying connecting speed:20~30m/min
constant tension control, float loading shaft type( off-line)
Max reel tension:0.7~1.5N/mm
AC frequency conversion sectional drive
Expect the main drive, the other calendering rolls and some leading rolls, spreader
rolls are equipped with auxiliary drive
Electrical and hydraulic control system
Main drive, reeling and unreeling drive are AC frequency conversion variable-speed
The reeling and unreeling drive are equipped with special operation card and tension
detecting feedback system. Reel and unreel emergency braking tome: 5~10s.
Auxiliary drive s speed and load distribution control.
The oil pressure of bottom roll and controllable crown roll is controlled by PLC.
The oil pressure can be tracked automatically according to the setting linear pressure.
The reel loading linear pressure can be adjusted separately.
Through PLC and field bus, control the machine operation and hydraulic system logic
operation. All the operation can be done through the touching screen.
The operation plant is equipped with buttons, knobs and indicator lights.
Inside and outside lifting table
Hydraulic drive, machinery synchronization, equipped with electrical, hydraulic,
Used for roll changing and maintaining.
Large frame and base plate are high-quality steel plate welding, machining after annealing.
The frame has high-strength, good rigidity and quality, good-looking appearance.
The frame is installed with base plate, which can insure the installing accuracy and reduce installing period.
Paper releasing stand, upright, rail upright of the lifting table, auxiliary drive support and spare roll support are steel plate cold bend section
bar welding, with good-looking appearance and symmetry structure.
Calendering roll quick and slow separating control technology, to insure the safety and reduce the shock.
The multi-zone controllable crown roll can control the sheet caliper smoothness variation, to enhance the product quality.
The calendering roll weight hydraulic compensation technique changes the drive arrangement form, control the two sides difference precisely,
improve the calendering result greatly, enhance the production capacity and extend the service life.
Separate paper threading is the fundamental change for the super calender operation.
Thermal roll consists of chilled cast iron body and two flange shaft heads.
The body is drilled surround to form the thermal oil channel.
The special design can insure the uniform surface temp.
Soft roll consists of intermediate body and two flange shaft heads.
The cover material is imported, done in domestic.
The body is equipped with stainless steel liner interlayer, forming the fluid flow passage with flange shaft heads and double-pass rotary joint, keep the soft roll working.
The spreader roll use composite bidirection multipoint spiral groove structure. When sheet width is large, it is better to use three-section
variable spreader roll.
Thermal roll oil heating use conduction oil electrical heating system.
The roll body temp use linear control system. Main parts and electrical control elements are imported.
Electrical control system is word famous brand.
In order to keep advancement and reliability, the following parts are imported:
Soft roll cover.
High-pressure oil pump, proportional valve, sensor, pipe joint,
hydraulic steel pipe, high-pressure tube in the hydraulic control system.
Controllable crown roll and hydraulic sealing elements.
Thermal oil rotary joint.
Main parts in thermal oil system.
Main parts in electrical control system.
