J. Cent. South Univ. (2020) 27: 3652-3666 DOI: https://doi.org/10.1007/s11771-020-4571-z Pressure impact characteristic of vane type continuous rotary motor under different buffer structures WANG... 150080, China Central South University Press and Springer-Verlag GmbH Germany, part of Springer Nature 2020 Abstract: In order to solve the problem of pressure shock on the continuous rotary electro......
Development of pressure control system in counter gravity casting for large thin-walled A357 aluminum alloy components LI Xin-lei(李新雷), HAO Qi-tang(郝启堂), JIE Wan-qi(介万奇), ZHOU Yu-chuan(周玉川...: Counter gravity casting equipments(CGCE) were widely used to produce large thin-walled A357 aluminum alloy components. To improve the pressure control precision of CGCE to get high quality castings......
J. Cent. South Univ. (2018) 25: 2085-2092 DOI: https://doi.org/10.1007/s11771-018-3898-1 Effect of aluminum particle on properties of viscous medium during warm viscous pressure bulging GAO Tie-jun... into viscous medium was proposed to improve the thermal conductivity of the viscous medium and the efficiency of warm viscous pressure forming (WVPF) process. The influence of aluminum particles on a viscous......

of pressure leaching are determined as sulfuric 5.10 mol/L acid, leaching time 150 min, temperature 90 ℃, and the H2O2 dosage of 0.5 mL/g or 2.5% KMnO4. The leaching rate of indium is more than 90... solutions. The stability of indium sulfide, zinc ferrite and solid-melt in sulphuric acid creates problems in indium recovery by hydrometallurgical processes. Pressure leaching can increase......
