| description | The problem of aluminum recycling in the Ukraine is particularly important problem due to the lack of primary production of the raw material in the country. Therefore for the aluminum production the reverberatory furnaces are used. The interesting solution, allowing reduce the amount of metal burned on the surface of liquid metal during melting. For this purpose, lightweight metal is grinded and then is melted in the vortex flow of liquid metal.
The disadvantage of existing system with vortex flow of metal is application of the centrifugal mechanical pump, reducing the reliability and service life of existing designs due to the pump blades operation in an aggressive environment of liquid metal.
To overcome this problem, the six-pole arc inductor was proposed to be used in the design. This paper provides a comparative analysis of two structural designs of the reverberatory furnace with an attached chamber of metal vortex. The driving force for a metal flow is created by a six-wave arc inductor.
The design efficiency was evaluated by the temperature difference between the maximum and average temperatures in the main part of the furnace bath. The option that provided the smallest temperature difference was considered as the best one. The angular speed of a liquid metal in the vortex chamber, which ensures the suction of grinded particles into the liquid metal volume, where their melting takes place, was also taken into account.
From the results of two designs comparison, the conclusion was made for tangential connection of the pressure channel (θ = 0), the best temperature uniformity was obtained in the furnace volume while at θ = 45° the best velocity and temperature distribution in the vortex chamber was occurred.
For a more detailed assessment of two designs simulation taking into account the formation of a meniscus on free surface of the liquid metal should be taken into account |

Результати у вигляді розподілу швидкості і температури рідкого металу отримані для двох варіантів (кутів) приєднання натискного каналу до вихрової камери печі. Показано, з точки зору перемішування рідкого металу у ванні печі кращим є тангенційне приєднання натискного каналу, а з точки зору функціонування вихрової камери більш ефективне приєднання під кутом 450.
