Ramming Paste

Ramming paste mainly include the following categories.

Cold ramming paste

You can tamp it at room temperature, construction convenience, no additional heating equipment. It can effectively reduce construction costs and energy consumption. It has certain plasticity before roasting, can better fill the gap between the cathode carbon block. And form a firm bond with the carbon block in the subsequent roasting process. To ensure the integrity of the cathode structure and electrical conductivity. It is suitable for electrolytic aluminum plants with special requirements for construction conditions or limited energy supply. Especially the construction and maintenance of small electrolytic cells.

Hot stamping paste

You need to carry out the tamping construction at a higher temperature, usually heated to about 100°C. Under this condition, its fluidity and adhesion are enhanced. And it can fill the gaps and pores of the cathode carbon block more closely, forming a more dense cathode structure. So as to have better conductivity and erosion resistance. This is suitable for large-scale and efficient modern aluminum electrolytic cell construction. It is helpful to improve the overall performance and production efficiency of the electrolytic cell. But it has high requirements for the construction environment and heating equipment, and the construction cost is relatively high.

Advantages

Good electrical conductivity

It can effectively conduct current to ensure the smooth electrochemical reaction in the electrolytic cell.

High temperature resistance

It can work stably in the high temperature environment of aluminum electrolysis (about 950-970 °C) for a long time. This maintains the integrity of the cathode structure.

Good adhesion with the cathode carbon block

It can be closely combined to prevent electrolyte penetration, thus extending the service life of the cathode.

In addition, we can customize the ramming paste according to different electrolytic cell design and process requirements during the production process. To meet diverse production needs and ensure the stability and efficiency of aluminum electrolytic production.

Uses of ramming paste

Ramming paste is widely used in aluminum electrolysis industry.

In the assembly process of aluminum electrolytic cell, cold ramming paste or hot ramming paste will be accurately filled in the gap of the cathode carbon block according to the actual situation. And after roasting and curing, a complete conductive cathode base with excellent performance will be constructed to build an electron transport path for the reduction reaction of aluminum ions. And it ensures the stable and efficient electrolytic reaction.

At the same time, you can use the ramming paste in the side to effectively protect the side structure of the electrolytic cell. And resist the erosion of high temperature electrolyte and aluminum liquid. Maintain the heat balance of the electrolytic cell and the stable state of the lining, reduce the heat loss. And improve the economic benefits and safety of electrolytic production.

In addition, different types of ramming paste with their own characteristics, not only used in the initial construction of new electrolytic cells, but also used in the maintenance and renovation of old electrolytic cells. For the sustainable and steady development of the aluminum industry to lay a solid foundation. This is the core basic material in the production of aluminum electrolysis.
