A typical Aluminium pot
Aluminium pot means where liquid aluminium gets produced using electrolysis method. Basic functioning needs alumina, carbon anodes and electrical current and some flux and bath materials for electrolysis process. To complete this process it must have a series of pots under one or many buildings called Pot rooms. Aluminium Pots (bottom) lined with cathode blocks and a cell is connected with the anodes. Normally, service life of pots depend on the life of cathodes which resists up to 2000-3000 days if everything goes well. After completing the service life all pots need to be relined with new pot lining materials which we supply to our clients with total satisfaction.
Key items are Cathode and anodes for the potroom. Anodes are made calcined petroleum coke, pitch and recycled butts. Alumina is transferred from the main smelter silos to the potroom usually by conveyors.
Cathode blocks are used in aluminium pot cell for bottom lining along with pre-fabricated side regulating and corner blocks. Grades: SJ-30, SJ-50, SJ-100, SJ-H* Our high quality semi-graphitic, graphitic and graphitised cathode blocks are low in electrical resistivity, strong resistant erosion to molten salts and liquid aluminum in the aluminum electrolytic cells. We therefore suggest our customers to choose different grades depending on their pot cell technology and pot amperage. These cathodes are produced by our own raw-materials. So, top quality materials can decrease cathode voltage and then reduce the power consumption and improve the service life of the cell. * In the grades number denotes the percentage of graphite used with ECA and ‘H’ stand for graphitized which is totally different product and key raw material is high quality calcined petroleum low sulphur coke. After normal baking process graphitisation process takes place under LWG furnace at >3000 deg C. We supply cathode blocks for all kind of cell technology whether it is AP, ALCOA, EGA, GAMI, SAMI, NEUI, P69 etc. For any specific queries, please write us and will reply as soon as possible. |

Alloying materials are available in various shapes and sizes such as tablets, mini-tablets, flakes, granules and powders.
These materials are widely used for production of primary and secondary aluminum and charged directly into liquid aluminum during melting process. We supply as per customers specific requirements.
