Abstract

The design of the mold electroslag furnace smelting hollow billets of metal blades having a water-cooled copper mandrel. The variants of the cooling circuit of the copper mandrel. A mathematical model, an algorithm for calculating the thermal state of the mandrel at the chosen geometrical parameters, a given number of cooling channels and the parameters of the cooling water. For copper inner mold 200 mm in diameter revealed that the stationary thermal mode occurs during the time not exceeding 5 minutes. It was established that the increase in the number of channels with the same total area of their cross section, leads to a reduction of temperature gradients, and its maximum value in an internal mold. Through software ANSYS engineering simulation conducted the thermal state of the copper mandrel proposed design for the given parameters of the cooling water. Calculations confirmed the adequacy of the proposed mathematical and computer models.
