Considering the characteristics of roll-forming, springback and microstructure changes during the welding process, the longitudinal residual stresses (LRS) of cold-formed square hollow sections (CFSHS) in the roll-forming and high-energy welding processes was simulated with finite element method. It is concluded that LRS of CFSHS at the outer and inner surfaces are basically equal in value and opposite...
Selective catalytic reduction (SCR) de-NOx reaction in flue gas is the main de-NOx technology used in power plants. In this technology, de-NOx catalyst is the key content of SCR technology. And the industrial experiment is the necessary link of de-NOx catalyst research process. In this paper, according to the power plant conditions, the industrial test platform was designed and carried out. The catalyst...
