Abstract

This paper comes up with a new baking approach, high temperature gas baking technology, based upon aluminium cells characteristics and raw material properties. Research achievements have been widely used in actual practice after numerous laboratory and industry tests. It turns out that, high temperature gas, as heating media, is able to ensure uniform surface temperature distribution of cathode lining. What’s more, it reduces the possibility of paste and carbon blocks oxidation damage during baking process. Its good baking results create favorable condition to prolong cells’ s service life. This approach is also proved to be energy-saving, safe and environment friendly.
