Problems solved by technology

[0002] The investment casting of titanium alloy is produced by centrifugal casting in a vacuum shell congealing furnace during smelting and pouring. The molten metal must be smoothly carried out in the mold cavity when the crucible is turned over, so that qualified castings can be poured out. Its structure is as in the present Existing technology "Technology Research on Direct Melting and Casting of Titanium Alloy Parts in Vacuum Consumable Condensation Furnace" (2006, Foundry, Zhang Jinlin) attached figure 1 As shown in , the structure of the centrifugal disc is only a single-column central support structure, which is prone to deformation caused by uneven force during the rotation process after weighing. In actual production, the deformation of the centrifugal disc will lead to the need to use Pads to adjust the stability of the formwork
The pads are not flexible enough

Abstract

The invention relates to a method for adjusting titanium alloy mold shell charging balance. The method comprises the steps of jack fixing, mold shell placement and centrifugal disk adjustment. The height and the position of the centrifugal disk are adjusted by a jack mounted on a bottom plate in a furnace hearth, and it is ensured that a mold shell can be filled with metal liquid steadily in the pouring process.
