【 摘 要 】

Heat treatment of aluminum ingots is a fairly energy-intensive production. Therefore, increasing energy efficiency in such processes plays an important role in reducing economic costs. The mathematical model of heat exchange occurring in the cooling chamber of aluminum ingots after homogenization annealing is considered. The model obtained made it possible to study the heat transfer in the cooling chamber. To improve energy efficiency and reduce economic costs, options for recycling hot air from the cooling chamber are offered. The estimation of economic efficiency from use of each of variants carried out.
