Aluminium & Alloy Rod Continuous Casting and Rolling Line
1.Machine Name & Type
UL+Z-1500+255/14 Aluminium & Alloy Rod Continuous Casting and Rolling Line
Specially for producing aluminium alloys rod of diameter 9.5mm for electrical wire, such as Al-Mg-Si
electrical conductor of high intensity. And also it can produce electrical aluminium rod. The line
is competitive with the relative international products level.
Tiltable type holding furnace designed to provide easy access for final preparation
of individual alloys..
In-line filter & degassing device to provide maximum quality liquid metal to the casting machine
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 inner cooling, 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..
Induction heater meets the temperature requirement of the cast bar for rolling process.
With the function of temperature rising, it can do heating and adjusting automatically.
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 aluminium
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 quenching and fast cooling.
The water pipeline makes a closed system by themselves with cooler, filter and indicator for main pipe
presssure and temperature.
To clean off the moisture on the surface of the aluminium 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 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 Aluminium rod is preformed before
entering the collection basket; on the other hand, the end of rod drops down into the basket automaticallyy
in case rod broken.
The transmission system is in type of DC motor (fully-digital) speed adjusting. By adopting PLC and man-machine
interface for the complete line control, it can display the different kinds of temperatures, such as the cast
bar, the beginning of rolling, emulsion and water for quenching. Also it can check and display the running
parameter of machines as well as indicate the breakdown.
