2. the turborotor listrium supports foundry goods profile antidote, it is characterized in that, the step that profile is corrected is as follows:
2.1, foundry goods heating: the turborotor listrium is supported foundry goods (10) puts into heating furnace, be warming up to 880 ℃～900 ℃, insulation 1h～2h;
2.2, foundry goods installs the location: the turborotor listrium that will heat supports the profile part that foundry goods is put into straightening die lower mold body (1) upper surface, its first gulde edge (10a) and first alignment pin (8) and second alignment pin (7) are reclined, second gulde edge (10b) reclines with alignment pin (9), tightens the band handle bolt (3b) in the compactor assembly (3) then;
2.3, profile corrects: install upper die body (2) additional, will correct mould behind the matched moulds and put into hydraulic press, apply 100T pressure, the dwell time is 20s～25s; Then, unloading pressure takes out and corrects mould, lays down upper die body (2), unscrews band handle bolt (3b), takes out the turborotor listrium and supports foundry goods;
2.4, foundry goods cooling: the turborotor listrium that takes out is supported foundry goods naturally cools to room temperature.
