| | Injection machine
JSC "ChMP" is the key partner of Russian producers of steel and cast
iron, engaged in melt treatment by introduction of cored wire and/or aluminium
rod. At present Chepetsky Mechanical Plant supplies 14 Russian metallurgical
enterprises with equipment for this purpose. Cored wire and injection machines,
designed for cored wire injection into melt, according to predetermined
programme, and produced at JSC "ChMP", can be used in metallurgical production
process for any type of extra-furnace metal treatment (desulfuration, alloying,
modification and other processes). When necessary, ChMP specialists render
competent assistance in equipment erection and commissioning. Further information
of injection-machines specific models is enclosed in accompanying technical
documents.
According to the manner of wire feeding two-channel injection-machines
have two drives (each channel can have its own feeding speed).
There are two variants of one-channel injection-machine:
|
 |
control and maintenance from the right |
|
|
|
control and maintenance from the left |
|
|
|
|
According to the manner of wire pressing down there are two variants of
injection machines:
|
|
manual pressing down |
|
Pneumatic pressing down |
|
|
According to control system there are three variants of injection machines:
|
|
control system basis - control counter-indicator(CCI) |
|
ontrol system basis - IBM compatible controller with serial interface
RS-232C |
|
control system basis - controller SIEMENS PROFIBUS-DP |
|
|
When making injection-machine delivery agreement, please specify the model.
Connecting cables are not included in delivery package, but can be
fabricated and supplied to a customer when specified in agreement.
Under agreement between producer and customer injection-machines base
models can be updated under customer specific request.

Auxiliary devices and machines.
Auxiliary devices and machines are not included in delivery package.
Fabricated under agreement. Performance specifications are available upon
request.
Lifting-pivoting machine serves as a guiding from injection-machine
to ladle, if there is no possibility to install fixed guiding, and according
to operation regulations it is necessary to remove it upside or aside.
Horizontal coil receiving rack serves for installation of wire coil,
when there is only slight height difference between mount place of injection
machine and a coil.
Vertical coil receiving rack serves for installation of wire coil,
when there is significant height difference between mount place of injection
machine and a coil.
Injection-machine installation diagram (advisable).
Injection-machines were designed as devices for cored wire injection,
but it is also possible to inject Al rod, provided that Al rod in coil
is arranged turn to turn and layerwise, the coil has the framing and installed
into device protecting from turn loosing, and unreeling is carried out
from inside. Wire coil should be placed at a distance no less than 3 -
5 meters, wire guiding from injection-machine to the ladle should be carried
out in tubes with inner diameter 45 - 50 mm and bending radius no less
than 1 meter. In two channel injection-machines guiding should be carried
out in different tubes.
Availability of coil receiving rack (horizontal or vertical) is not
the obligatory operation condition, it is possible to install wire coil
in framing (with a pallet or without a pallet) on a floor, retaining dimensions
shown in diagram. |
