Unit instructions
1 main rolling mill
The main rolling mill is the important part of the continuous cold
rolling mill . It includes base, frame, reducer, motor etc. Each
frame is driven by an independent motor. All the basic rolling
process is finished on the main rolling mill, and the number of the
frames is different according to different rolling size.
2 guide system
2.1 each pass has entry and exit guide, odd frame of entry guide
glides to lead in, and even frame rolls glides to lead in.
2.2 guide material : GCr15
2.3 guide hardness: HRC55-58
3 pay off
3.1 scope of application : Φ20mm
3.2 max dia : Φ1600mm
3.3 max load capacity :3t
3.4 inside frame dia: Φ500mm
3.5 height of bobbin : 1000mm
4 Coiling take-up machine
1 This machine consists of draught gear and take-up device, meets
the characteristics of taking-up enclosure and requirements of
constant taking-up speed. As the rotate speed must be steplessly
adjusted within certain area, the AC inverter motor is adopted, and
connected with rolling motor. The traction power is from the AC
inverter motor, and goes through the drive shaft to drive the
coiling basket.
2 scope of application:Ф8.0mm
3 max dia of looping:Ф1500mm
4 max pulling speed:3m/s
5 max weight of looping:3ton
6 traction electric motor:power 3kw,can speed regulation and
linkage with rolling mill
7 coiling electric motor:power 3kw, can speed regulation and
linkage with rolling mill
5 Oil lubrication system
5.1 oil flows through pump to filter, passes roll organization and
oil tube of the main reduction
box ,then flows through branch oil tube, bearing to spray oil
lubrication. It includes:
5.2 oil pump: KCB-55 1
5.3 filter: SPL-40-B-X 1
5.4 oil box: 1m3 1
5.6 max stream flow: 2.3m3/h
5.7 working pressure: 0.33MPa
5.8 oil temperature: 35～45℃
5.9 oil tank capacity: 1m³
5.10 cooling way: use external circulating water cooling
6 Emulsion system
6.1 In order to improve the surface quality of the cold rolling
copper rod, emulsion cool and lubricate the roller , copper rod and
guide device in the rolling process. The emulsion coming out from
the emulsion station flows into main tube, and then use joint to
connect to rolling system and guide device. The return emulsion
flows back to the return groove on the rolling pedestal and then
flows into the emulsion pool through returning main tube.
6.2 centrifugal pump: 50BPZ-42 20m3/h 1 (provided by buyer)
6.3 filter: SLQ-50 1 (provided by buyer)
6.4 max stream flow:25m3/h
6.5 working pressure:2.2kgf/cm2
6.6 emulsion temperature:35-45℃
6.7 emulsion pool volume:15m³
6.8 cooling way: self cooling
6.9 emulsion component: adopt DL178 which is used in big drawing
machine,concentration 12%
7 electrical system
The electrical system includes the power system and the controlling
system.
The power system supplies the power to each inductor through
several power panels. The control system assures the normal
producing, the recording and displaying of the data.
8 feeding and straightening device
The feeding and straightening device is in front of the main
rolling mill, and it is used to straighten the rods so that it can
feed the rod easier.
6 water cooling system
The water cooling system is an independent water recycling system
which supplies the cooling water for the crystallizer, the water
jacket and the induction coil. It includes one 80M2 water pool,
water pump, pipelines and the cooling tower. It insures that the
inlet water temperature is around 20-35℃, the flow rate is about
50m3. For a good heat exchanging effect, the user need to prepare
the water soften device.
7 electric control system
The electric control system includes the power system and
controlling system. The power system supplies the power to each
inductor through several power panels. The control system assures
the normal producing, the recording and displaying of the data. The
detail recording and displaying information is inductor voltage,
current, furnace temperature, water temperature(including the
crystallizer water temperature), traction speed and traction
distance etc.
8 feeding system
The feeding system feed the whole piece of copper cathode by the
electric hoist. It assures that the copper cathodes is supplying to
the melting furnace continuously.
9 temperature testing system
The temperature testing system includes two parts: copper liquid
testing and water testing. The testing result is shown on both on
the digital temperature meter and the industrial control scream for
producing monitoring.
