Oil-free aluminum alloy rod continuous casting and rolling line is used to produce aluminum alloy rod with finished rod diameters of 9.5mm,12mm. The productivity ranges from 4T-4.5T per hour, and the cross-sectional area of the casting bar ranges from 1500 to 2400 mm2. The weight of coiled rod is about 1.5T-2.5T.
During production of AL-alloy rod, induction heater ensures the process temperature requirement of the casting blank for rolling, with the function of heating and adjusting cast ingot.
The continuous rolling machine has function of automatically feeding and rods stacking stop. Continuous quenching device can have quenching online, the outlet of the guiding pipe is quipped with a water blowing device to clean off the moisture on the surface of the aluminum alloy rod.
Meanwhile, it is also equipped with an active traction gear to ensure a smooth delivery of the aluminum alloy rod. The arc guiding pipe is a trolley-guiding construction to reduce the scratch upon the aluminum alloy rod surface. The rod is coiled by means of centrifugal laying head.
On the one hand, the aluminum alloy has pre-deformation before entering the rod collection frame; on the other hand, the end of rod drops down into the frame automatically in case of broken rod. Given that the device of frame changes for wire rod accumulation, the rod coils are kept in order in collection frame to realize continuous coiling.
2.1 Level casting and automatic casting system ensures no turbulent current, the molten aluminum feeding to casting system is oxide-free.
2.2 Online degassing unit removes the contents of hydrogen and impurity in the molten aluminum with the small dispersed bubble by the inert gas.
2.3 Induction heater heats the casting bar before entering the rolling mill, and adjusts temperature automatically, thus achieving good electrical and mechanical properties.
2.4 Oil-free coiling system with rollers makes it possible to produce oil-free aluminum rod without the use of grease, which can save production cost and make workshop clean.
