PCT No. PCT/FR79/00101 Sec. 371 Date Jul. 7, 1980 Sec. 102(e) Date Jun. 11, 1980 PCT Filed Nov. 7, 1979 PCT Pub. No. WO80/00978 PCT Pub. Date May 15, 1980. The invention relates to a process for packing, also known as lining, electrometallurgical furnaces. The packing is produced from a concrete which is poured in situ or in precast blocks, composed of a setting cement having a low water retention capacity and low porosity and of an aggregate of which at least a proportion is a carbonaceous product such as anthracite. This packing has a noteworthy resistance to the constituents of fluoride-based igneous electrolysis baths and to liquid aluminum. Application to the packing of igneous electrolysis cells for the production of aluminum.
