INFLUENCE OF TECHNOLOGICAL AND CONSTRUCTIVE PARAMETERS ON THE INTEGRITYrnOF THE BOTTOM OF ALUMINUM REDUCTION CELLS DURING FLAME PREHEATING

摘要

The effects of preheating technology, cathode block materials andrnother factors on the integrity of the cell during flame preheating ofrnaluminum reduction cells were investigated. The temperaturernfields, gas dynamics, and stress-strained state of the reduction cellrnduring flame preheating were studied using mathematicalrnmodeling in an ANSYS finite-element package and Star-CDrnCFD-package. The best way to cover the peripheral seams duringrnpreheating has been identified.
