Abstract

Based on researching aluminum melting technology and casting rolling process as well as controlling the key parameters of production process and analyzing the microstructure

aluminum rod with excellent properties were produced.The results show that the ultra-fine drawn aluminum rod can be produced by controlling hydrogen content in liquid aluminum alloy below 0.15mL/100 g

setting rational cooling water as well as controlling grain degree of the billet to grade 1.Through the control of the key parameters of the rolling process

such as temperature of the rolling process and concentration of the emulsion

the produced aluminum rod can been drawn to 0.12 mm

and the wire breaking rate of the drawing process is reduced to 110min/times.
