预焙铝电解槽三维槽帮形状的模拟计算
Simulation calculation of 3D freeze profile in prebaked aluminum reduction cells
摘要
Abstract
The APDL was used to loop through the PREP7, SOLUTION and POST1 modules, so as to relocate the nodes on the surface of the freeze. Then, the 3D calculation for the side-ledge profile was fulfilled. Taking a 180 kA aluminum electrolysis cell as the numerical example, based on ANSYS, the quarter thermal-electric model was developed, and the thermal conductance contact from the melt to the frozen electrolyte, the anodes and bottom cathodes was introduced in order to express the corresponding thermal convection. More dimensional information was included in the 3D-1/4 cell model, and influences of electric were considered because it was thermal-electric coupled field calculation, both of which made this calculation method closer to the real situation. The results show that the 3D frozen profile obtained agrees very well with practical situation, and the frozen electrolyte of the endwall is thicker than that of the sidewall, and the corner has the thickest side ledge. This computation method can be used to guide the design of developing cell structure.关键词
