Cathode Paste Cold Ramming Paste Used in Joints Between Cathode Graphite Blocks Peripheral Seam
Ramming pastes is widely used in aluminum reduction cell, blast furnace, smelting
furnace, industrial silicon smelting,ferroalloy
furnace and other industrial furnaces. The main purpose, both in the joints between the cathode blocks and
in the peripheral seam, is to fill the voids between the prebaked
blocks and prevent metal and bath from penetrating the cathode.
Leakage of metal and electrolyte damages the cathode and may lead
to premature pot failure.
Ramming paste is a critical part of the cathode. Consistent and
high-quality ramming paste products installed according to
optimised procedures are required to provide a basis for improved
operation and longer pot life.
