1.Machine Name & Type
UL+Z-1800+255/12 Copper Rod Continuous Casting and Rolling Line
Copper Scrap Continuous Casting and Rolling Line
2.Machine Application
According to the different kinds of production material (copper cathode or copper scrap), we can equip
with different kinds of copper treatment furnace to produce ETP rod and FRHC rod of 8mm separately.
3.Machine Characteristic
Optimum capacity gas fired shaft furnace with automatic oxygen control system.
The continuous casting machine has been awarded the patent right.
Crystallizing wheel is in type of "H", on every side of which there is an adjustable nozzle spraying
water to ensure the crystal of the cast bar close and equal.It is easy for outer cooling and side
cooling ring to rotate out from the crystallizing wheel to adjust and maintain the cooling water.
Stainless steel is adopted as material for nozzles, inner or outer or side cooling rings, each of which
is equipped with pressure indicator and flowrate adjusting valve. The pneumatic system is used for
tightening steel belt, easy for adjusting. To clear off the moisture on the surface of the steel belt,
we adopt the flame sprayer(, the carbon coating device) and the wiper relatively.
The continuous rolling machine has a function of automatic feeding and rods stacking stop.
With an unique rolling method combining 2-high rolling stand with 3-high rolling stand, the copper
rod is provided with a good mechanic performance. The rolling emulsion and oil pipe form a closed
system with the cooler, filter and indicator for pressure of the main pipe.
The production line is provided with the function of continuous reverting for rod surface and fast cooling.
The cooling water makes a closed system by itself with cooler, filter and indicator for main pipe presssure.
To clean off the moisture on the surface of the copper rod, a blower is fixed at the end of the guiding pipe.
At the same time, an pinch-roller is installed to ensure a smooth delivery of the copper rod. The arc
guiding pipe is in a trolley-guiding construction to reduce the scratch upon the wirerods surface.
The rod is coiled by means of centrifugal (laying head). On the one hand, the copper rod is preformed before
entering the collection basket; on the other hand, the end of rod drops down into the basket automatically
in case rod broken. The collecting basket is slewing slowly and centrifugally to form orbital coils
convenient for decoiling.
The transmission system is in type of DC motors (fully-digital) speed adjusting. By adopting PLC and man-machine
interface, it can control the host and the assisting parts in type of complete line interaction. Also it can
check and display the running parameter of machines as well as indicate the breakdown.
