1235铝合金铸轧过程中分流块对型腔中液流的影响

Effect of Split Blocks on Aluminum Liquid Flow Behavior in Casting-rolling Process of 1235 Al-alloy

应用ProCAST软件对型腔中铝液流动过程进行了模拟。模拟结果表明,型腔熔体流动行为受分流块相对位置、分流块结构尺寸、分流块数目的影响很大。使用小尺寸分流块、合理的分流块数量可以使型腔中铝液分布更为均衡,能够获得更均匀的流速分布。

The aluminum liquid flow process in cavity was simulated using ProCAST software. The results show that the relative position, ＇structure size and the number of split blocks have great influence on flow behavior of melt in cavity. Using the smaller split blocks and the reasonable split block number can make the distribution of aluminum liquid in the cavity more balance and obtain more evenly velocity distribution.
