Abstract: Castex (continuous
cast and extrusion) is a latest metallurgical technology. Making
of AS wire (aluminum-clad steel wire) by Castex is an advanced
bonding technology of bimetal. In order to study the deformation
character of AS wire the numerical simulation is performed with
FE method. From the simulation result the following conclusions
are obtained:① The simulation is carried out sequentially in
three zones: initial extrusion, extrusion, cavity-filling and
bonding.②In the first zone the shearing deformation governs the
whole zone, while in that of cavity-filling, the deformation
mainly concentrates on transition arc of the concave mould. In
addition, in the last zone, the dominant deformation lies at the
boundary of concave mould, surface of steel wire and entry of
sizing band. Due to the movement of steel wire, the direction of
shear stress on its surface is opposite to that on the boundary
of concave die.
