The temperature field and flow field of high temperature melt in the nozzle in the casting-rolling copper process were simulated by the ANSYS software.The results reveal that at a fixed castingrolling temperature

with the increase of casting speed

the solidification position of roll-casting billets is gradually shift to right

and the flow uniformity is increased.However

the over-high rolling speed is harmful for forming of roll-casting billet and roll of the plate.At a given roll-casting speed

with the increase of pouring temperature

roll-casting billet solidification position is shifted to right gradually

however effects on the flow field distribution can be ignored.The optimized processing parameters were presented as follows:roll casting temperature of 1 150 ℃～1 170 ℃and roll casting speed of 600 mm/min～1 000 mm/min.Based on the optimized parameters

the T2 copper continuous roll casting slab was formed successfully.
