The preparation process of superalloy has been upgraded and the quality has been improved significantly
1. Innovation ability of forging metal smelting technology
Various modern chemical parts production and manufacturing technologies and production and processing equipment are constantly designed and matured, such as thermal control freezing, fine grain technology innovation, pulsed laser injection molding repair technology innovation, high wear resistance workpiece thermal spraying technology, etc. The original technology innovation capability is constantly improved and matured, so the product quality consistency inspection and safety reliability of various nickel base superalloy workpiece equipment are constantly improved. Nickel base superalloys containing little or no aluminum and titanium are generally melted in annealing furnace or induction furnace. When refining high aluminum and high titanium nickel base superalloys in the atmospheric environment, the eddy current loss of elements is not easy to inhibit, and mixed gases and impurities enter more, so vacuum system should be selected for refining.
Because it further promotes the substantial reduction of the concentration of impurities, alleviates the state of the impurity distribution area and the precipitation structure of casting and rolling, the dual technological innovation capability of combining metal smelting and secondary remelting can be selected. The primary methods of metal smelting include annealing furnace, induction heating furnace and non induction heating furnace;
2. Innovation ability of precipitation metal smelting technology
In recent years, the innovation ability of directional cultivation precipitation technology has been developed because the grain boundary vertical to the stiffness axis and porosity in forged alloy steel have been reduced or eliminated. This technological innovation capability is to make grains grow along a precipitation direction during the freezing process of alloy steel to obtain parallel columnar crystals without transverse grain boundaries.
