In lining parts to be stamped of an aluminum electrolytic cell by filling a carbonaceous stamping material into the part and stamping the filled stamping material, a mixture consisting essentially of a carbon aggregate and a binder and being capable of being stamped at a temperature above 100 DEG C. is prepared; a solvent for the binder containing aromatic hydrocarbon as a main component in an amount insufficient to effect stamping of the stamping material at room temperature, but sufficient to stamped at a temperature of 50 DEG to 100 DEG C., when added to the mixture; the mixture and the solvent are mixed together, before application, to prepare a carbonaceous stamping material; and the carbonaceous stamping material is applied to the part of the cell to be stamped at a temperature of 50 DEG to 100 DEG C. to effect the lining of the cell, whereby the stamping environment can be greatly improved by eliminating generation of pitch fumes and hot vapors and at the same time deterioration in physical properties of the stamping material is substantially prevented. |
