Exempt from raft raw material in the accumulation of melting cold bed；When raw material adds melting cold bed, 1#, 2# electron gun power and drawing ingot speed degree are instant
Matching；Sprue channel open among the refined cold bed of titanium liquid stream and crystallizer, and when beginning to flow into crystallizer, open 3# electron gun
Overflow figure and adjust to optimum position；When titanium liquid stream is into crystallizer, the heat preservation figure of 4# electron gun is opened, it is ensured that ingot casting
Head quality opens the rifle overflow figure of 4# electron gun and close to sprue channel open side when titanium liquid is paved with crystalliser feet completely；When
At the end of founding, 1#, 2#, 3# electron gun are successively closed, retains 4# electron gun and carries out feeding, supplement metal liquid institute in flowing
The heat of stream, makes metal remain liquid condition；
(5) opening flow of inlet water control valve makes full of cooling water in cooling chamber, and metal liquid is poured by crystallizer top middle portion
Road junction at the uniform velocity flows into the crystallization cavity of crystallizer, and the cooling water in cooling chamber uniformly cools down metal liquid, passes through water
The water temperature of warm detector test cooling chamber water outlet, it is cold to guarantee by adjusting flow of inlet water control valve and water flow control valve
But the water temperature difference of chamber inlet and outlet is not higher than 20 DEG C；When crystallizer fills up metal liquid, and liquid level is begun to ramp up, start
Drawing ingot is carried out, liquid level is maintained on same interface, drawing ingot speed degree is (2 ~ 4), after reaching estimated length, adopt
Metal liquid feeding is carried out with 4# electron gun, is entered under working chamber under the traction of ingot pulling mechanism by the cooling ingot casting of crystallizer
Portion simultaneously carries out 90 ~ 100min of vacuum cooled in working chamber lower part, is then again put into ingot casting and draws ingot room, closes working chamber's isolation
Valve is opened and ingot room is drawn to rush the cooling valve of argon, carries out rushing the cooling 90 ~ 100min of argon to ingot casting, makes ingot casting true to drawing ingot room to vacuumize
20 ~ 25min is handled under empty condition, then rushes the cooling 100 ~ 140min of argon to ingot casting progress is secondary, and ingot casting is pulled to and draws ingot room bottom
Up to titan alloy casting ingot.
