Explosive clad plates of 917 low magnetic steel and aluminum alloy of LF5, LF21, LF11 etc are designed by explosive welding of different metal, and experimental research on the mechanics of steel and aluminum clad plate and metallographical study on interface of clad plate are carried out.
In this paper, by performance analysis and test of Monel400 and 16MnR, the welding method and procedure were determined, good welded joint was gotten, the problem of welding of different metal Monel400 and 16MnR was resolved, and it was used successfully in manufacture of chemical industry equipment.
This paper gives the application of explosive welding technology in the field of different metal welding and complex metal material production. In addition,other new explosive working technologies adopted in nuclear engineering are also introduced.
2) The rates of absorption of different metal ions were different at the same developmental stage. In 10 day culture, the rates of uptake of most metal ions were 5%/g, but that of Se_75, Ab_83, Sr_85 and Zr_89 were 10%-30%/g.
At the same conditions, when adding different metal oxides with different proportions, the removal rate of COD is improved to 38.3～48.6% from 32.5%. The removal rate of color is improved to 47～60% from 42%.
The results show that different metal oxides have different effects on the structural stability and catalytic activity of the catalysts, among which CeO2 and Bi2O3 can enhance the stability and activity of the catalysts.
The calculation basis and simplified calculation methods were provided all the fixed parameters of different metal item in formula were changed to a constant after calculation and only the frequency was retained as variable.
3. In order to obtain good ohm contact, the experimental project is designed by adopting Kelvin photochart. The sheetary contact resistances of the samples are measured under ali kinds of condition, such as different substrate growing temperature, different alloy temperature, different alloy time and different metal contact.
Aromatization of ethylene was carried out over different metal supported HZSM-5 catalysts, in particular over Ga(Zn)/HZSM-5 catalysts. The zeolite acidity, the amount of supported metal and the reaction temperature strongly influence ethylene aromatization.
Based on the conductivity and density of the particles being two important factors to influence the separation results,the separation of different metals is studied with a principle that the deflection of different metal particles has great difference under the same operation conditions.
