Furnace carbon electrode is a carbon conductive material made of electric calcined anthracite, petroleum coke, graphite crumbs, coal tar pitch, etc. as the main raw materials, through batching, molding, roasting, and mechanical processing. It is mainly used in submerged arc furnaces and is widely used in the smelting of metals or non-metals such as industrial silicon, ferroalloys, calcium carbide, and yellow phosphorus.
Composition and manufacturing process
The main raw materials of furnace carbon electrodes include electric calcined anthracite, petroleum coke, graphite crumbs, and coal tar pitch. The manufacturing process includes batching, molding, roasting, and mechanical processing.
Application field
Furnace carbon electrodes are widely used in submerged arc furnaces, mainly for smelting industrial silicon, ferroalloys, calcium carbide, and yellow phosphorus. Its application advantages include:
Cost-effectiveness: Carbon electrode production does not require a graphitization process, and the cost is relatively low.
Performance advantages: Carbon electrodes have low resistivity, low self-consumption, high volume density, low ash content, good antioxidant properties, and significant power saving.
Environmental advantages: Carbon electrodes are not easy to break during use, reducing unnatural losses, and are more environmentally friendly than electrode paste.
Comparison of alternatives
Compared with graphite electrodes and electrode paste, carbon electrodes have the following advantages:
Lower cost: Carbon electrodes do not require graphitization, and construction and operating costs are low.
Better performance: Carbon electrodes have low resistivity, high thermal efficiency, short smelting time, and high output.
Better environmental protection: Carbon electrodes cause less pollution during use, while electrode pastes will generate a lot of pollution during use
