Application and advantages of electrode paste

In the process of producing carbide, ferrosilicon, ferromanganese and other ferroalloys, the smelting temperature needs to be increased, which can meet the production requirements only by inputting a strong current into the furnace through special electrodes.

In order to make the electrode work normally at high temperature in the electric arc furnace, the electrode itself needs to have good conductivity, oxidation resistance and thermal shock resistance. Only the electrode paste produced with carbon raw materials can meet the harsh smelting requirements under continuous arc high temperature above 3000 degrees. Therefore, electrode paste plays an important role in the above-mentioned thermoelectric furnaces, so it is called the “heart” of this kind of electric furnace.

Application and advantages of electrode paste

The electrode paste is a kind of “continuous self baking electrode” in terms of its use method and properties. In the process of use, the outer layer of the continuous self baking electrode is a cylinder made of 1-2 mm thick steel plate. The electrode paste is regularly added to the cylinder. With the trend of production, the electrode paste gradually softens – melts – roasts, and releases a large amount of volatile during roasting. When it enters the conductive clip of the electrode, Because of the high temperature, it changes from semi coking to complete coking, * becomes a conductive carbon electrode, and the cylinder formed by steel plate melts into the furnace charge. The electrode paste is baked into a conductive electrode by various heat of the electric furnace itself, so it is called a self baking electrode.
