PRECISION FORMING METHOD FOR LARGE-SIZED COMPLEX CAVITY TITANIUM ALLOY CASTING

WIPO Patent Application WO/2021/174375

A1

A precision forming method for a large-sized complex cavity titanium alloy casting. The method employs a precision casting composite coated shell-mold die and a graphite casting mold to manufacture the large-sized complex cavity titanium alloy casting. The composite coated shell-mold die and the graphite casting mold are degassed and then assembled into a casting mold, a consumable electrode is placed into a vacuum consumable electrode arc furnace for smelting, and a titanium alloy solution is casted into the casting mold by employing a titanium alloy centrifugal casting process, and the large-sized complex cavity titanium alloy casting is produced after centrifugation. The utilization of the present process to manufacture the titanium alloy casting increases the size precision, interior quality, and surface quality of the casting, greatly reduces the rejection rate of the casting, reduces the casting costs for the casting, and shortens the production cycle of the casting.
