The temperature and strain distributions of the mockup composed of Cu-alloy with distinct structural material (SS316L and China Low Activation martensitic steel (CLAM)) were calculated and analyzed, based on a high heat flux (HHF) test recently reported with heat flux of 3.2MW/m2. The calculated temperature and strain results in the first wall (FW), in which SS316L is as the structural material, showed good agreement with HHF test. By substituting CLAM steel for SS316L the contrast analysis indicates that the thermo-mechanical property for CLAM steel is better than that of SS316 at the same condition. Furthermore, the temperature and strain distributions of the FW were calculated under the condition of normal ITER operation: the surface heat flux is about 0.5MW/m2 and volumetric heating due to neutron radiation is on the order of 15~20 MW/m2.
In production process of continuous casting slab in ferrous metallurgy, in order to realize soft reduction and obtain continuous casting slabs without internal defects, it is important to determine the location of final solidifying end of slabs exactly. In this paper, a set of physical simulation device which simulates detecting the final solidifying end was designed according to similarity theory. Through experimental study and mathematical statistic method, we analyzed the influence of each factor on the detected results. The research results may provide certain guidance for the on-line detection final solidifying end in situ.
The temperature and strain distributions of the mockup composed of Be, Cu-alloy with distinct structural material (SS316L and China Low Activation martensitic steel (CLAM)) were calculated and analyzed during thermal cycling, based on a high heat flux (HHF) test recently reported with heat flux of 1.5MW/m2. The calculated temperature and strain results, in which SS316L is as the structural material, showed a good agreement with HHF test. By substituting CLAM steel for SS316L the contrast analysis indicates that the thermo-mechanical property for CLAM steel is better than that of SS316 at the same condition. Furthermore, the temperature and strain distributions of the FW were calculated under the condition of normal ITER operation: the surface heat flux is about 0.5MW/m2 and volumetric heating due to neutron radiation is on the order of 15~20 MW/m2.
