The writer gives a systematical analysis on the cause of serious deformation of 186kA aluminum electrolytic pot shell and provides a specific reparation plan,which has made a satisfactory result.

The analysis of pot shell changing laws and cradle frame swelling laws is given by discussing the changing laws of caloric expanding pressure on the appearance of liner.

Report the measuring of aluminium pot shell swelling right after the pot start-up.

Study on the 3D heat transfer model of the aluminum reduction cell shells based on the method of simulation;

Analyzing the blushing of the pot shell and its countermeasures;

The paper presents the technical modification of 160kA smelting cell in Baiyin Honglu Aluminum Corporation,which has settled once and for all the problem of cell shell aging and optimized the technical and economic indicators of the cell.

Galerkin method is adopted to set up a equilibrium equation for global side-torsion stability analysis of a U-shaped and rectangle thin-shell aqueduct,and a calculation formula for critical load is deduced.
