Product Description Paper Machine Super Calender Product DescriptionThe super soft calender is the new generation most advanced calender in recent years. 12-roller super calender12-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.Product features1.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.Main Data:Trimed Sheet Width max 6000mmOperating Speedmax 1500m/minPaper Threading Speedoff-line operating:5~15 m/min online operating: the same as PM and coaterWorking Liner Pressuremax350N/mmThermal Roll Surface Temp180oCNumber of Calendering Rolls6~12Top and Bottom Roll Typemulti-zone controllable crown rollThermal Roll: shell materialalloy chilled cast ironSurface HardnessHSD72surface temp variation±1oCSoft Rollroll cover is imported, done by special manufacturersCalendering roll loading and releasing stylebottom tank loading,and releasingThe loading oil tank is controlled by PLCQuick releasing and slow releasingCalendering roll quick releasing time ≤0.5sCalendering roll weight hydraulic compensating systemhydraulic entire or sectional compensationThermal roll heating systemElectrical heating, body temp linear control The heads of soft roll is cooled by blowingPaper release type( off-line)Constant tension control motor brake to release paperUnder emergency stop, motors generate electricity to brakeMax unreel tension: 0.7~1.5N/mmReel change flying connecting speed:20~30m/minReel Typeconstant tension control, float loading shaft type( off-line)Max reel tension:0.7~1.5N/mmPaper Threadingseparate threadingDriveAC frequency conversion sectional driveExpect the main drive, the other calendering rolls and some leading rolls, spreader rolls are equipped with auxiliary driveElectrical and hydraulic control systemMain 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 tableHydraulic drive, machinery synchronization, equipped with electrical, hydraulic, machinery safety device.CraneUsed for roll changing and maintaining.Main feature: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.Antifriction bearing.Main parts in thermal oil system.Main parts in electrical control system.
