Abstract
A method of applying a treating liquid to a porous body ( ), in particular a pre-baked carbon component of an aluminium production cell, such as an anode block, a cathode block or a sidewall. In this method first the body ( ) to be treated is inserted, with its part to be treated facing up, in the treating chamber ( ). At least one sealing member ( ) is then applied to the body so as to isolate a space ( ) in an upper part of the treating chamber ( ) around the part of the body to be treated from a lower part ( ) of the treating chamber around a bottom part of the body which is not to be treated. Next, treating liquid ( ) is supplied to the upper part ( ) of the treating chamber to cover the part of the body to be treated with the treating liquid and applying a vacuum to intake an amount of the treating liquid into pores in the part of the body to be treated. Then the body ( ) is freed from the sealing member(s) ( ), and removed from the treating chamber ( ).
