During the last decade, China rare earth (RE) industry has made significant progress and become one of the most important producers in the world. In this paper,
Solvent extraction is now finding applications in a broader range of fields than the past. Many of these applications require process equipment with shorter con
For on-line monitoring of welding quality, the characteristics of the arc sound signals in short circuit CO2 GMAW were analyzed in the time and frequency domain
The chamber device was designed and set up to simulate the in-service welding. The results show: the ts/5, t8/3 and inner wall peak temperature Tp decrease with
A new method of collision-free path plan integrated in virtual processing is developed to improve the efficiency of laser surface hardening on dies. The path pl
