Abstract：

The heavy cylinder forgings are key parts in the energy industry,such as nuclear power and petrochemical.Its manufacturing technology is crucial to the domesticalization of fundamental equipment in China.The main application fields and importance of heavy cylinder forgings were introduced and the performance requirements and the characteristics of materials used were discussed.The development of its manufacturing technology was studied,which showed the large and micro to be the main trend in the field of heavy cylinder forgings.The conclusion is that the most essential factor to improve the quality of heavy cylinder forgings is casting and the form of the die,while,the implementation of controlling forging with the order of refining the inner grain structure is the key factor.
