SY610-4Γ1830 type four roller calender and auxiliary equipment
A. Calender (host machine)
1. Calender: feed material from top and make final production from
bottom, roller diameter Ф610 mm, roller surface width 1830mm, the
surrounding drilling and oil heating, line speed of the calender
5-50m/min. The piece coming out from the roller of the calender has
display apparatus gap of rollers distance. Right driving.
2. 1# and 2# rolls are cold-cast alloy roller and surrounding
drilling, surface hardness HS68-74 ° C, the rollers’ surface hard
chromium plating fine grinding, coating thickness 0.1mm, the
rollers surface roughness Ra = 0.05μ, surface comprehensive
Material of 3# and 4# rollers is alloy forging flaw detection
processing, the rolls’ surface hard chrome plating, coating
thickness 0.18mm, hardness> HRC60 ° roll, surface roughness Ra =
0.01μ, surface comprehensive precision 0.05mm, roll surface
temperature no less than 230 ° C, the roll surface temperature
error ± 1 ° C;
1-4# rollers surface had no middle height, 1-4 # rollers all
surrounding drilling, roller surface chromium plating without
pinhole, the roller polished and process degassing after fine
3# and 4# rollers hard chrome plating after hot mill processing.
3. Bearing use the Wafangdian production taper bearing, bearing
pedestal use ductile iron.
Transmission and power
4. Drive power of 1# roller and 4# roller of Calender: 55KW (in
this calender main and auxiliary equipment use AC motor), and the
remaining 2# and 3# roll: 75KW power. Main and auxiliary can tune
speed by linkage and also division. (Calender is equipped with
blackout emergency opening device, UPS devices purchased by buyer).
The motor of calender adopts AC motor speed regulation, Siemens
Beide motor, Japan Yaskawa governor, other electricals adopt
Controllable pitch device: setted at 1, 2, and 4# roller. The 3 #
roller is fixed roller.
5. calender 3# roller mounted shaft cross-device, cross regulation
20mm, adjust the speed 3mm/min, driving drive: at each end with a
three-phase brake motor of planetary reducer of, worm gear, use
adjusting spindle to control crossover amount, universal ball joint
head between the spindle and the bearing pedestal, on the other
side use the universal ball joint head and hydraulic cylinder to
connect, the hydraulic cylinder is used to locate and eliminate
transmission parts clearance.
6. 4# roller has pre-load device, installed in the outside of the
main bearing of 4# roller, positive bending, embody bending by
hydraulic cylinder, the bending amount is adjustable, embodied by
adjusting a hydraulic pressure, the maximum bending amount is
equivalent to the roll height 0.05mm.
7. The calender rack uses 40mm steel plate welded after heat
treatment and then finishing, the roller face and rack wall open
file 15 cm according to bearing, stainless steel rack. Distance
between the stripping roller and 4# rollers is 5mm.
8. roller bearings lubricated with thin oil forced circulation
lubrication device for roller bearings and bending bearing
lubrication, automatic cycle, dual-pump system (one pump for work
and one pump for spare), pressure-protection, every road flow
shows, lubricants automatic temperature control (automatic heating
and cooling), oil temperature overheating protection ,work and
spare pump can switch when working. Bearing lubrication is as same
as Ф660 × 2300.
9. hydraulic pressure: a separate set of hydraulic station for roll
bending, axis cross and embossing devices, adopts variable oil pump
two sets(one for work and one for spare, can be switched each other
while working). Roller bending and embossed by hydraulic pressure,
which can manually adjustable, and with pressure display, hydraulic
station standard configuration.
10. calender heating system four sets, each roller needs one set,
oil heating oil pump motor power 5.5KW; when oil heating, each
roller is equipped with two sets of proportional valve smart to
control oil temperature, the maximum heating temperature 230 ° C,
accuracy ± 1 ℃. With water cooling apparatus.
11. device: 1# and 2# roller set striker plate device, a motor
reducer drive screw nut and then drive striker plate, both ends can
single-action or linkage, contact with the roller and striker plate
is made of copper. One root screw two root polished rod.
12. emergency brake: rack mounts 4 sets and operation table mounts
an emergency stop switch, when happening emergency stop, roller
rotation less than 90 ° (no load and maximum speed) and roller open
nip by high speed.
