Soderberg Electrode Paste is also called Anode Paste, Self-baking Electrodes Paste or Electrode Carbon Paste. It is produced from calcined petroleum coke (or calcined pitch coke, Electrically Calcined Anthracite Coal), calcined anthracite, coal tar pitch and other additional materials. It is used as conductor in submerged arc furnace under self-baking process while manufacturing different types of Ferro Alloys and Calcium Carbides.
Used in the formation of electrodes, in electric reduction furnaces, for the production of iron alloy, calcium carbide, thermophosphate and other types of furnaces.

Soderberg Electrode Paste is fed into smelting furnaces column in different forms: cylinders, eggs, briquettes and polygonal blocks. Blocks and cylinders are moulded into pieces in medium to large dimensions related with different electrode sizes.
Soderberg electrode paste in briquettes and blocks, used for the formation of electrodes of electric furnaces for reduction of alloys of silicon, manganese, nickel and for the production of calcium carbide, thermophosphate, among others.
Soderberg Electrode Paste in briquettes and blocks, for the formation of FER’S electrodes (reduction electric furnaces) for the production of Iron-Silicon with low titanium content. Maximum titanium content of 20 ppm in Raw Paste.
Hot and cold coating pastes. Used for coatings in electric reduction furnaces, iron alloy casting pots and aluminum reduction tanks.
Electrode Paste Briquettes:
60x80x100 mm
Electrode Paste eggs:
Electrode Paste Cylinders:
Ø500, Ø600, Ø700, Ø800, Ø900, Ø1000


1). briquettes are loaded in bulk or packed in big-bags
2). cylinders are steel strapped on wooden pallets and can be covered with plastic foil


1). Low Electrical Resistivity
2). High Mechanical Strength
3). Low Porosity

The waterproof graphite for process equipment is manufactured in two main steps at Ao Hui Carbon company, First, synthetic graphite is made. Then this material is impregnated with phenolic resin to make it waterproof and improve the mechanical characteristics.
Ao Hui Carbon company uses exclusively graphite of higher quality. Our process uses a fine grain, homogeneous graphite, with a compact grain structure, an optimal distribution of grain and pore sizes and free of structural irregularities such as cracks, large pores or impurities.
Ao Hui Carbon company has developed in close collaboration with a renowned European resin manufacturer, a phenolic resin that is optimized for the type of graphite it uses in its manufacturing processes.
Manufacturing Process of Synthetic Graphite

The manufacturing process of synthetic graphite includes numerous steps: powder preparation, shape moulding, baking, impregnation or densification of the coating, re-baking and finally, graphitization.

Market Advantages Product

As we have the technique and production process above, our products have excellent quality.

As the production is close to the place of production of the raw materials, we can efficiently reduce the cost of production, for that reason, we have an evident cost advantage
As in the application of the product of the electrode paste there is a comparatively high technical requirement, that’s why the service is an important aspect that presents the competitive corporate strategy, for that, our company installed the special and professional after-sales service group, always is prepared to provide efficient support for customers.
