3. Parameters and description of technological equipment

Pay-off stands
Type	"Duck neck"
Productivity	>2.5 ton
Unwinding supports for each wire	2 sets (4 sets in total)
Wire can be replaced without stopping the machine.
Entangling wire switch
Number of emergency stop switches	2 pcs
Purpose	on loss of production line must be protected.
Entangling wire switch consists of a ring of large diameter fixed on spindle, ring and spindle are joined to the cover perpendicularly. In operation rod passes freely through the ring. However, if the rod is entangled it falls from the unwinding rod support, which makes the ring and spindle move forward, turn off the limit switch, located on the cover, and immediately stop the drawing machine setting the line in motion, in order to avoid wire breakage.
Reservoir for water washing under pressure
Length	1.4 m
Material	PP
Circulation pump	1 set with corrosion-resistant coating on 1.1 kW.
Purpose	removing loose residues on the wire surface in order to reduce residues amount, entering the electrolytic acid etching reservoir that extends the service life of the acid etching solution.
Water is fed into the upper working reservoir via circulation pump arranged to jet direction, water supplied to the upper working reservoir, pours back into the circulation reservoir. Gas purification system is installed at the outlet of the reservoir body, it prevents water drops on wires entering the reservoirs of the next processing stage. Gas resource used for gas cleaning, is a stream of medium pressure provided by the Customer (the same way).
Electrolytic acid etching reservoir
Length	8.2 m
Material	PP
Rectifier	2 sets, one set - the circulation pump with corrosion-resistant coating, a second set - plate heat exchanger, it is possible to cool the acid solution, the temperature is displayed in digital form, there is an ability of automatic adjustment.
Purpose	The reservoir is designed for complete electrolysis acid etching, providing physical and chemical reaction on the wire surface in the electrolytic solution, as well as providing power control of physical and chemical reactions by adjusting the concentration, composition, temperature, current, time and polarity to achieve the removal of oxidation layer from the wire surface.
Upper working tank is installed with a lead plate inside. The polarity of the lead plate for each group of the working tank is arranged as follows: ++ - ++ reservoir is fully equipped with 3 groups of upper working tank. Gas purification system is installed at the outlet of the tank body, preventing water drops on wires entering the reservoirs of the next processing stage. Extract hood is mounted on the tank body, behind the mating flange of the extract hood exit section the Customer will provide a connection to equipment for processing or diversion.
3- leveled reservoir for water washing
Length	2.5 m
Material	PP
Circulation pump	3 sets with corrosion-resistant coating.
Purpose	complete removal of residual electrolytic solution from the wire surface.
Pure water is added to the third block of the storage reservoir, third block rinsing is performed by means of circulating pump jet rinsing. After rinsing water is poured into the second block of the storage reservoir again, at the same time the second block rinsing takes place by means of circulating pump jet rinsing and so on. Then after rinsing water is drained. Gas purification system is installed at the outlet of the tank body, preventing water drops on wires entering the reservoirs of the next processing stage.
Water washing reservoir with preheater
Length	2.0 m
Material	stainless steel.
Temperature control	digital display, automatic adjustment accuracy ±4°C, heating temperature >60°C.
