Abstract

The paper presents a prototype of an open- type induction channel heater designed for maintaining the temperature of molten aluminum. The feasibility of induction heating of molten aluminum in an open horizontal channel without critical deformation of the free surface or the occurrence of a pinch effect has been experimentally confirmed. The results of experimental investigations are presented, including measurements of overheating temperature, heating rate, and heat losses through the casing. It was established that the average heating rate within the temperature range of 701–735 °C is 5.4 °C/min, making it possible to compensate for heat losses during metal transportation and to provide additional heating of the melt directly during the casting process. The combination of the proposed method with conventional control algorithms enables precise temperature regulation with an accuracy of 1–3 °C, which is critically important for the production of high- performance aluminum alloys, where maintaining a narrow temperature range determines the stability of the microstructure and the properties of the final product
