The article examines the current state and prospects of aluminum production in Ukraine and the world. It is shown that the production of secondary aluminum in Ukraine is economically feasible and its share is constantly increasing. The analysis of information sources showed that the demand for aluminum is constantly growing, but due to the increase in energy prices, the cost of production has increased significantly, which has led to a decrease in the volume of its production. Therefore, it is necessary to implement measures to improve the production process, which will allow to increase the level of energy saving in the production of metal. An analysis of the heat balance of the melting furnace for the production of secondary aluminum was carried out. The analysis of the heat balance showed that in the production process there are significant energy losses due to the insufficient use of heat in the technological process, including the heat of the combustion products, which is either not used effectively or not used at all. The main methods of increasing the energy efficiency of melting furnaces are considered and a list of measures to improve their operation is proposed, which will reduce the cost of metal production. Schemes for heat utilization of waste gases from melting furnaces are calculated and designed. The heat balance of the furnace before and after modernization was compiled. Calculations of the heating surface of the recuperator-air heater have been performed.
