Brief Information on the Lining of Reduction Cells

The reduction cell is lined with carbon cathode blocks and a side lining. The voltage to the cathode is supplied by steel collector bars and collector bars. Below the carbon blocks are the layer of refractories and the heat insulation layers (Fig. 2.7). 

The carbon cathode blocks may be full-length or split. They may be up to 3,500-3,900 mm in length, 750 mm in width, and 550 mm in height. 

Carbon cathode blocks are installed (Fig. 2.8) on the refractory barrier layer. 

The gaps between the blocks are 30-40 mm, while the peripheral seams between the end of the cathode blocks and the peripheral side lining are up to 150 mm. They are filled with carbon ramming paste. Today there are alternatives to the manual ramming of gaps with hand rammers and the machined ramming with special devices they are more convenient because of the elimination of the human factor. 

The side lining is made from silicon carbide blocks or from carbon side-wall blocks.
