The current situation and the future mission of the industrial standardization for the heavy casting and forging in China have been analyzed in this article,and issues existed in current standardization work of the heavy castings and forgings as well as the key emphasis in the standardization work for the future have been set forth as well.

Research in the Process of Cuboid Heavy Forging;

Study on Healing of Interior Crack-type Fault in Heavy Forging by Modeling;

In order to control the microstructure of heavy forgings,an optimization method based on composite design and numerical simulation was proposed.

The Repairing Study for the Defects Inside the Heavy Forgings;

Microstructure of heavy forgings robust parameters control methodology based on taguchi method;

In order to control the microstructure and fracture of heavy forgings,a multiobjective optimization method based on numerical simulation was proposed.

Numerical simulation and experimental validation of large forging during quenching process;

Our research invented one process of pre-heattreatment to correct the coarse original structure and the grain unhomogeneous of large forging, the process improved the mechanical properties of the forging.

According to the complexity and particularity of large forging process design, as well as the shortcoming of traditional manual method for process design, the key technologies of CAPP system are discussed, and the structure and function modules of forging CAPP are designed in this paper.

The study on the mould flux for heavy casting;

The types of burning-on defects of heavy castings and their formation reasons were introduced,and the influences of some factors on the effect of coatings to prevent burning-on defects were analyzed including:ingredients of the coating, combination of refractory granularities,high temperature stability,sintering property,peeling off property,and so on.
