4, main composition of the production line equipment
4.1 Two conjoined frequency cored induction furnace
The electric furnace is mainly composed of a furnace
cover, a furnace shell, an induction body, a support, an electric
control system, a temperature measuring system and a cooling system
of the equipment.
The furnace shell and the bottom bracket of the upper
furnace body are welded with the Q235 steel plate and the steel
plate, and the lower part of the smelting induction body and the
heat insulation induction body are connected with the upper furnace
body through a flange. Melting groove is made of red copper
casting; core with Japan Z10 silicon steel laminations loaded into;
coil with double glass ribbon wrapped rectangular copper winding
and, good insulation, strong cooling effect; water cooling jacket
is made of stainless steel plate 1Cr18ni9Ti thickness 3mm, it has
high strength, vibration magnetic effect good. The furnace chamber
is divided into three cavities, the melting chamber, the
intermediate excessive cavity, the thermal insulation cavity.
Melting chamber of material function; excessive cavity is mainly
static copper water, reducing smelting furnace material temperature
fluctuation effect of furnace temperature on the thermal
insulation, heat preservation cavity is mainly to give traction bar
provide stable molten copper and stable temperature.
Two conjoined frequency cored induction
furnace control system, melting and insulation department are
used step self coupling voltage regulating transformer to adjust
the pressure, adjustable pressure profile of 380V, 340v, 300V,
270V, 240V, 210v, 180V, 150V, 120V, 90V voltage (line). Melting,
thermal insulation furnace temperature control are equipped with
manual and automatic conversion switch, when the switch is in the
manual, artificial regulation of voltage knob for regulating the
output voltage of a transformer, so as to control the power output
of the electric furnace; when the switch is arranged in the
automatic control system by artificial intelligent temperature
controller to adjust the output voltage of the transformer
pressure. An automatic temperature control system is arranged in
the heat insulating part of the smelting part. The thermocouple is
a horizontal inserting type, and the heat insulating part is an
inserting type.
4.2 copper alloy lead mould
The mold is made of one cooling and two cooling. The
cooling jacket is made of heat resistant steel, and the other parts
are made of cold rolled steel sheet. With water grooves in the mold
on the cooling water in the mold directional flow, so as to ensure
the uniformity of cooling.
Cooling water distribution system is specially
designed for the cooling of the mould. The system is provided with
a water inlet flow meter and a water outlet thermometer, which is
convenient for the user to monitor and adjust the water system. In
order to ensure the stability of the water supply of the
crystallizer, the addition of a crystallizer water temperature
control system is composed of plate condenser intelligent electric
control valve, a temperature controller, when there is a change in
water temperature of mould, temperature change signal transfer to
the intelligent electric control valve, the system sends signal to
the intelligent electric control valve, intelligent electric
control valve according to the given signal, automatic control the
size of the water flow, of plate condenser cooling intensity of
automatic adjustment, so as to ensure the stability of the water
temperature of mould.
4.3 four column servo drive up lead machine
The upper guide machine is composed of four upright
posts, an upper and a lower moving screw rod, a servo power part, a
power transmission part, a pressing traction roller part and a
process operation system.
Four post bracket is composed of a hollow square pipe
welding, the up and down moving wire rod part is by motor, worm
gear and worm gear reducer, chain and wire rod is composed of a
power transmission system.
When the holding furnace copper water level change,
through the copper water level tracking detection system, transmits
the signal to the automatic control system of convey instructions
to the motor, motor according to the instructions on the mobile,
and copper water level changes also passes through the liquid level
tracking system will transmit the signal to feeding alarm system,
alarm alarms, suggesting that operator feeding.
The traction of the traction machine is composed of a
servo motor, a speed reducer, a gear system, a transmission shaft,
a traction roller and a pressing roller.
Process operation system mainly consists of anti interference of
operating platform, servo system, 10.5 inches color man-machine
interface, contactor and a button, controlled by PLC and
man-machine interface, the interface can display speed,
4.4 Coiler with a core reel
Composed of a frame, a power transmission system and
a wire collecting plate. Frame is welded by steel I-beam and drive
consists of a motor, a speed reducer, a transmission shaft
composition; speed by frequency modulator for motor frequency
change to control motor speed.
The take-up disk comprises a disk body and swelling
mechanism. When the strip a roll, by the expansion mechanism of the
contraction will strip out.
