摘要

采用SolidWorks软件建模与Fluent流体模拟软件相结合

模拟了不同铸造速度下水平连铸硬脆合金Co-Cr-W丝材在结晶器内的温度分布、速度分布状况

并分析了铸造速度对凝固壁厚度和内部质元速度的影响。试制了合金圆坯丝材

并对模拟结果进行了验证分析。结果表明

当铸造速度为1.5m/min时

合金液既能形成有效的壁厚

又不存在蓄能现象

较为适宜。模拟分析结果与实际结果相符合。

Abstract

Based on SolidWorks software combining with the Fluent software

the temperature and velocity distribution in process of horizontally continuously casting brittle Co-Cr-W alloy wire were simulated with different casting speeds

and effects of casting speed on wall-thickness of solidified shell and internal solute diffusion were analyzed.Meanwhile

Co-Cr-W wire was trial-produced to verify the simulated feasibility.The results show that with casting speed of 1.5m/min

the effective thickness of solidification shell can be formed and the energy can be consumed completely.The simulation results are well in agreement with practical ones.
