Germany took the lead in the development of ductile iron nuclear spent fuel container, and the application field of ductile iron has been greatly expanded. According to their own actual situation, various countries have formulated relevant standards for ductile iron, such as din1693 ductile iron standard (Germany), jisg5502-2007 ductile...
1.For the first time in China, the research and production of 100 ton ductile iron nuclear spent fuel container was carried out, and the metal mold casting process was proposed; 2.The temperature field and mold temperature curve of the 45 ° sector specimen were successfully measured by the self-developed...
Compared with the development of ductile iron nuclear spent fuel container at home and abroad, in the development of 100 ton ductile iron nuclear spent fuel container in Germany, the impact property of – 40 ° C has not been designed and measured, and sand casting process is adopted....
In 1991, Gong Jinying of Qiqihar Institute of light industry studied the relationship between the micro fracture morphology and mechanical properties of large section ductile iron container with different wall thickness. Fourteen tensile fracture specimens were selected from five different isothermal surfaces on the fan-shaped block for SEM observation....
The purpose of jsri and Nippon Steel is to develop and produce the ductile iron nuclear spent fuel container with the size of 4850 mm ＞＜ 2450 mm and inner diameter of 1490 mm. The test of small proportion specimen is used to master the key technology of producing...
Siempelkamp company of Germany began to develop 100 ton ductile iron nuclear spent fuel container in 1987. During the development of the container, the company found that the hardness of sand sample greater than 3Mpa is helpful to realize the riser free casting of 100 ton ductile iron nuclear...
The metal container for dry storage is the key equipment for the transportation and storage of spent fuel, and it is a non-standard equipment. It needs to be designed and manufactured according to different types of components. The inherent safety of the container is the fundamental guarantee to ensure...
Germany has realized the mass production of 100 ton nodular iron nuclear spent fuel containers, and has produced more than 1100 100 ton nodular iron nuclear spent fuel containers; Japan has also done a lot of research work on 100 ton nodular iron nuclear spent fuel containers, and has...
Based on the simulation analysis of the casting process of 100 ton ductile iron nuclear spent fuel container, the 45 ° sector test block was designed and the solidification temperature field of the 45 ° sector test block was measured. The microstructure and properties of the 45 ° sector...
In order to eliminate the adverse effect of hot spot, reduce the defects of ductile iron spent fuel container and ensure that the structure and properties meet the requirements, Germany adopts sand mold cold iron casting process in hot spot. Through simulation and experimental research, metal mold is used...
