摘要
针对等离子弧冷床精炼钛合金过程,运用COMSOL有限元仿真软件,基于电场、磁场、流场和温度场多物理场耦合,建立简单的等离子弧-熔池耦合冷床精炼钛合金模型,在等离子弧热作用下钛合金开始熔化,随着熔炼时间的推进,水冷坩埚中钛合金快速形成液态熔池,形似椭圆,并在35秒后进入准稳态,最后进行实际精炼测试,为制备钛合金粉末质量优化提供理论指导.
Abstract
It focuses on the process of plasma arc cold bed refining titanium alloy.Using COMSOL finite element simulation software,a simple plasma arc melt pool coupled cold bed refining titanium alloy model is established based on the coupling of electric field,magnetic field,flow field,and temperature field.Under the action of plasma arc heating,the titanium alloy begins to melt.With the advancement of melting time,the titanium alloy rapidly forms a liquid melt pool in the water-cooled crucible,resembling an ellipse,and enters quasi steady state after 35 seconds.Finally,actual refining tests are carried out to provide theoretical guidance for optimizing the quality of titanium alloy powder preparation.
