Abstract Scope |
A new glue that does not contain any carcinogenic compound has been developed to be used at the sides of the aluminum electrolysis pots either against the shell or between silicon carbide sidewalls and preformed blocks. Such glue has been built to replace SiC mortars which usually exhibit poor sticking properties during ramming operation or even during pot life, and insure thermal efficiency. The different requirements and characteristics that are needed will be presented, and the final properties obtained on the new AD20+ glue will be given. AD20+ glue has been used at pilot scale with EQUIBRAS equipment, in comparison with some silicon carbide mortars. The trials performed with the EQUIBRAS machine relate to glue or mortar installation and to unsticking tests with pressure measurements. This AD20+ glue has already been installed in pots and some performance data will be given. |
