The casting fluidity,ratio of line contraction,casting stress and heat crack tendency were tested.

A datermination and analysis have ho aide on the llowability,contraedon cavity ratio andcasting stress of the medium-chromium wear-resistant cast steel.

To eliminate the destructive effect of the casting stress of BF cooling stave on the functioning of the stave body,this paper presents a novel approach to remove the water protecting the brick and to eliminate the casting stress through BF drying process.

The amplitude of casting residual stress without aging can be in a very low level when vibrating solidification is processed at the low order natural frequency of metal mould system.

VC reinforced Fe matrix composites were produced by reactive casting process.

Research Progress of Optimization of Die-casting Technology Parameters;

The results show that the wear resistance of the composites are better than the matrix alloy, while the die-casting technic makes the SiCp/ZL102 parts much better than the ingots.

Present status of China s die-casting industry is introduced, the new technology and new process of die-casting are generalized and analyzed from die-casting design, process, equipment and die-casting testing areas, as well as, the development direction of die-casting industry is discussed.
