Audited Supplier | Rongxing cathode ramming paste with different binder system. Include: Cold ramming paste, hot ramming paste, ramming paste of steel bar Rongxing 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. |

Notes of Cold Ramming Paste
1. Do not squeeze during loading and transportation to avoid tamping in advance.
2. Storage conditions require normal temperature, avoid light and avoid wind. 3. The storage time of cold paste should not be too long, and the shelf life is generally within one year, to avoid the paste from drying out due to the evaporation of the binder.
The use of expired or dry cold ramming paste may cause delamination and uneven quality
during construction, increasing the risk of leaking during roasting and operation.
