Abstract：A new titanium alloy casting process was developed, in which the graphite mold of the titanium alloy casting was tilted at the design stage, and the pouring system was set up at the thickness of the casting, so as to achieve tilting centrifugal casting. At the same time, the surface quality and internal quality of two castings were compared by vertical gravity casting and centrifugal casting respectively. The results show that the inclined centrifugal casting casting process can reduce the flow mark defects on the surface of the casting, improve the quality of titanium alloy casting, reduce the subsequent repair welding dressing, shorten the production cycle and reduce the production cost.
