摘　　要：本文研究了不同速度调节幅值对铸嘴型腔流场和温度场的影响,通过仿真分析,结果表明:入口速度变化幅值越大,型腔出口处熔体速度、温度过渡到稳定速度、温度的时间越长.这就为找出布流调整可行域,实现铸嘴型腔流场和温度场的在线调节提供了依据.In this paper , the influences of adjusting amplitude at different velocities on the flow field and temperature field at the exit of tip cavity are investigated. The simulation results indicate the larger the adjusting amplitude is, the longer time it takes the exit temperature and velocity transit to stay steady.This knowledge provides basis to find out the feasible adjusting zone for disposing fluid to realize adjusting the flow field and temperature field in tip cavity online.
