对紫铜连续铸轧过程铸嘴内高温熔体的温度场与流场进行了数值模拟。结果表明,在铸轧温度不变的情况下,随着铸轧速度的提高,铸轧坯的凝固位置逐渐前移,熔体的流动均匀性增加,但是铸轧速度过高不利于铸轧坯的成型和铸轧的立板;控制铸轧速度不变,铸轧坯凝固位置随着铸轧温度的提高逐渐前移,但铸轧温度对流场的分布影响相对较小。优化的铸轧温度为1 150～1 170℃、铸轧速度为600～1 000mm/min,在该工艺参数下成功实现了工业生产上的T2紫铜连续铸轧板坯制备。
The temperature field and flow field of high temperature melt in the nozzle of continuous casting process of copper are numerically simulated. The results show that with the increase of casting speed, the solidification position of the billets gradually increases and the flow uniformity of the melt increases. However, the casting speed is too high to favor the billets The forming and casting of the vertical plate; control the casting speed unchanged, the solidification position of the casting billets with the increase of the casting temperature gradually move forward, but the casting temperature of the distribution of the impact of the flow field is relatively small. The optimized casting temperature is 1 150 ~ 1 170 ℃ and the casting speed is 600 ~ 1 000mm / min. Successfully realized the T2 continuous casting of slab on industrial production under the process parameters.
