A continuous casting and rolling process of ZL114 Aaluminum alloy wire rod was established.Microstructure analysis of wire shows that the grain size of the edge of the wire is the smaller than the size of the core.With the rolling process

the core grain size of the cross-section of the wire is refined gradually

and the grain of longitudinal section is elongated along the deformation direction

meanwhile

distribution of the second phase is also changed from distribution along grain boundaries to distribution along the deformation direction.Welding test reveals that continuous casting-rolling technology can be used in the production of welding wire blank.
