Study of the Main Reasons for the Consumption of Graphite Electrodes in Electric Arc Steel Furnaces

Graphite electrodes are widely used in various industries, especially metallurgy. Their key features include inertness to most process environments, and electrical conductivity. However, there are a number of problems due to the peculiarities of the operating conditions. Graphite materials have good inertness towards gases, liquids and solids, as well as high electrical conductivity. In metallurgy, graphite electrodes are used in steel-making furnaces to supply electrical energy to the working space of the furnace. The article analyzes the main reasons for the consumption of graphite electrodes, both in normal and emergency situations. In the conclusion of the article, analyzes are made based on the results of graphite electrodes breakdowns.
