Strip Casting of Al-25%Si Alloy

摘要：

　　Strip casting of Al-25%Si strip was tried using an unequal diameter twin roll caster.The diameter of the lower roll (large roll) was 1000mm and the diameter of the upper roll (small roll) was 250rmm.Roll material was mild steel.The sound strip could be cast at the speeds ranging from 8 m/min to 12 rn/min.The strip did not stick to the roll without the parting material.The primary Si,which existed at centre area of the thickness direction,was larger than that which existed at other area.The size of the primary Si was smaller than 0.2 mm.Eutectic Si was smaller 5μm.The as-cast strip was ranging from 2mm to 3mm thick and its width was 100mm.The as-cast strip could be hot rolled down to lmm.The hot rolled strip was cold rolled.The primary Si became smaller and the pore occurred around the primary Si after the rolling.
