Effect of Si Content of Al-Si Matrix on Roll Cast Wire Inserted Strip
Effect of Si content of Al-Si matrix on roll cast wire inserted strip was investigated in this paper. 99.5％A1, Al-4％Si, Al-12％Si and Al-18％Si were used as matrix. Slit depth of the nozzle, superheat of melt, wire-diameter and roll speed was chosen as the casting parameters, too. Addition of the Si was useful to prevent the reaction between the matrix and the wire. A downward melt drag twin roll caster could cast the wire inserted strip of the Al-Si matrix of which Si content was ranging up to 18％. Composite strip, which matrix was hyper eutectic Al-18％Si, could be cast at the speeds up to 20m/min. The gap between the wire and matrix became thin when the superheat was high. When the slit depth of the nozzle was too shallow, the wire could not be inserted in the strip. The thickness of the wire inserted strip became thinner as the roll speed became higher.
