Summary of color coating aluminum plat:
After coating treatment, the aluminum belt material is beautiful
out surface and generous, wildly use for juice container, coating
shaping plate, metallic furniture, household electrical appliances,
food package, communications and transport and building industrial,
more and more intimate in daily life, and quality requirements of
coating is become more higher, so the aluminum belt material
factories in abroad are established the coating production line in
progression with higher quality. The highest speed of the
production line can reach 365m/min, width of belt material is
300~1880mm, and own some proprietary technology: single slipway
roller coat, powder coating technology, coating machine and control
system, welding and drying system, suspended welding oven,etc.the
main equipments are include entrance and exit
equipment,purifier,inaction equipment with traditional method(dry
and action on site),primary coating machine, precise coating
machine, decorating machine, welding oven, incineration system, gas
cooling and water cooling tank, cool/hot film, embossing machine,
automation process system, and so on.

Use fork truck or factory’s crane or other transportation tools
to move the coil which has a sleeve to the support stand at the
entrance of the decoiler(generally there is two or three support
stands), then lift the coil to the decoiler by an entrance coil
car, decoiling the coil by the decoiler, feed in the pinch roller
and cut off the head of the coil, enter the stitcher and stitch
with the end of the last coil, cure the stitched place with press
machine, then enter the entrance loop with the tension(the line
which has edge trimmer and withdrawal straightening stands should
trim edge and straighten first). When changing coil, the entry
section stops, and feed by entrance loop(normal line speed is
kept),The entrance speed will rise up to the specified running
speed after the stitch of the head of fresh coil and end of last
coil has been completed. The entrance speed will reach the normal
running speed after the entrance loop has reached its normal
storing length. The strip leaving the loop will enter the coating
room and coat after water cleaning and rinsing and passivation and
then dried by air knife. The strip is solidified in the solidifying
furnace after coating. The solidifying temperature is about
260℃.After leaving the solidifying furnace, the strip is cooled
down to the room temperature after the cooling in the air-cooling,
water sprays forced cooling and air knife cooling. Then wax and
static oil coating on the surface of the strip. It passes through
the exit loop and enters into the exit section. The exit section
includes an inspection platform, which is used to inspect the
surface quality of the strip. The exit zone will stop meanwhile the
operating section is running in its normal speed by the storing
function of the exit loop after the coil reaches its specified
length, weight or diameter.
The final coil is transferred to the support stand by the exit coil
car meanwhile the coiler has finished the pulling through coil and
established a stable tension. The draper-type wrapper retracts and
the speed of the exit section reaches its specified running speed.
The speed of the exit section will reach its normal running speed
after the exit loop has reached its normal storing length.
Compostition of equipment:
composition unit
of equipment | function declaration |
Elevating hydraulic car | Moving the coil to the decoiler or coiler by adjusting the position
of the car to load and unload the raw material AL coil. |
Decoiler | By adjusting the car, send the raw material AL coil to the
collapsible drum and tension the coil hydraulically. Feed the coil
by rotating the drum. |
