“…In order to solve the problem and improve the technical and economic indicators of metal production, measures to reduce the consumption of electrodes for melting are of great importance. Consumption depends not only on their quality, but also on the furnace design, technological and operating factors the melting temperature and character of the furnace atmosphere, quality used scrap steel grades (ordinary assortment, cord steel, stainless steel), application of fuel -oxygen burners and their location, see Table 1 [4][5][6].…”

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.

One of the major problems in electric arc furnace is the high temperature which results in thermal stresses and cracks within the material of the furnace surrounding walls. An effective cooling technique is needed to avoid such problems. For this purpose, a novel roof configuration of an electric arc furnace is used to provide efficient cooling to reduce the temperature in the roof material. The roof consists of two solid materials, namely, copper and alumina brick. The roof cooling is achieved by a water circulation within the roof. A numerical model using finite element method was implemented to solve the heat conduction equation with the complicated boundary conditions to find out the effects of using brick material with geometrical size variations for different values of thermal conductivity on the temperature distribution within the roof. The results showed that the decrease in brick material thermal conductivity resulted in a significant decrease in the top surface temperature of the furnace roof. The results showed that rectangular brick material is the best option in the roof to keep it at low temperature.

“…With the integration of the thermocline storage tank, it was found that it was possible to fully detach the fluctuating energy source from the constant steam production. Other attempts to improve the overall energy efficiency of EAFs with the help of heat recovery technologies include usage of phase change materials combined with superheated steam generation [8], application of nonlinear model predictive control methods [9], employment of advanced systems for cooling and heat recovery [10], etc.…”

A process and energy analysis was performed for an Electric Arc Furnace for steel production in order to determine the energy efficiency defined as losses contribution in the total energy input. Process analysis was performed during operation for one batch, measuring the relevant process parameters. Energy balance revealed that a significant potential for improvement exists, the main directions being reducing the cooling water loss (for example, by implementing a heat recovery system), reducing the loss during loading and adjustment by implementing technology changes and automation and reducing the loss through exhaust gas. Although implementation of heat recovery systems on the cooling water circuit and exhaust gas duct will not influence the actual process energy efficiency, it is expected to improve the overall energy expenditure by integrating other heat consuming equipment.
