Ramming paste is produced from calcined petroleum coke, calcined anthracite and various binders. It is used for gap and seam filling between bottom and sidewall cathode carbon blocks in aluminium reduction cells.
Leakage of metal and electrolyte damages the cathode and may lead to premature pot failure. The usage and installation of high quality ramming paste ensures optimal operation and enhanced pot life. Ramming paste is also used for hearth construction in foundry furnaces, iron and steel-making furnaces and for tap hole closing in electric arc furnaces.
