Cold Ramming Paste

What Is Cold Ramming Paste

Cold ramming paste is a carbon material used for masonry, widely used in aluminum electrolysis cell, blast furnace, smelting furnace, calcium carbide furnace, and other industrial furnaces, filling the gap between charcoal and cooling equipment, charcoal and charcoal, charcoal, and firebrick.

Cold ramming paste is made from high-temperature electrical calcite anthracite coal, artificial graphite, and natural graphite. Coal tar pitch, coal tar, and anthracite oil mixed oil additives as a binder, through the broken, ingredients, stirring and kneading for construction at ambient temperature.

Main Applications

Cold ramming paste is widely used in industrial kilns such as aluminum reduction cells, iron-making blast furnaces, smelting furnaces, calcium carbide furnaces.

Using Guide

Do not squeeze during loading and transportation to avoid tamping in advance.

Storage conditions require normal temperature, avoid light & wind.

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.
