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.
