“…However, the current forming speed is 2 m/min, which is much lower than the production speed of the traditional roll forming process. Due to the high efficiency and speed of induction heating, its high energy utilization rate, and its independence from the material and thickness of the plate, it is suitable for large-scale industrial production [33]. This study is important for the development and improvement of steel curtain walls.…”

This paper describes the use of cold and hot composite forming technology to produce pointed curtain wall profiles. An electromagnetic–temperature coupling model was constructed using ANSYS to study the temperature and electromagnetic field distribution during the forming process. Numerical simulation was used to optimize the process parameters to obtain the optimum heating parameters with a current of 4000 A, a frequency of 35 kHz, and a duration of 2 s. The accuracy of the model was also verified through experiments. The simulation results show that the use of a conductive magnet can improve the induction heating efficiency, increasing the heating frequency and the temperature peak; however, it also increases the temperature difference. Sharp-corner curtain wall profiles were successfully produced using the optimized process parameters. The temperature of the heating zone was measured using an infrared thermal imager, and the relative errors between the maximum heating temperature obtained from the simulation and the actual measured values were 5.37% and 5.02%, respectively, indicating that the finite element model performs well in terms of prediction.

“…At the same time, it is being constantly optimized with respect to the first implementations of such a heating method (in reference to the alternative, resistance heating) through reducing the energy consumption, increasing the efficiency and the quality of the heated material [14,15]. The main problem existing in the construction of devices at the beginning of their implementation was the heating technique itself [16][17][18] as well as the temperature stabilization with a linear course, which unfortunately caused significant decarburization and scaling of the external surface of the material, especially in the case of a steel charge with a high carbon content [19]. Additionally, we can differentiate between sections of constant and varying frequency inductors.…”

This study performs a complex analysis and review of the currently applied methods of inductively heating the charge material in hot die forging processes, as well as elaborates and verifies a more effective heating method. On this basis, a device for inductive heating using variable frequency inductors was designed and constructed, which made it possible to reduce the scale and decarburization with respect to the heater used so far. In the first place, the temperature distributions in the heater in the function of time were modeled with the use of the CEDRAT FLUX software. The aim of the research was to analyze the temperature gradient and value diversification on the surface and in the material core, as well as to determine the process stability. The following stage was designing and constructing a heater with an automatic system of loading and positioning of the charge on the exit, as well as with a possibility of working in a fully automated system adjusted to the work center. The last stage of investigations was the verification of the elaborated effective heating method on the basis of a short production series and a continuous work for the period of 8 h, both in the quantitative and qualitative aspect (reduced oxidation and decarburization as well as a gradient between the core and the surface). The obtained results confirm the effectiveness of the proposed solution referring to heating the charge material, especially in the aspect of stability and repeatability of the process, as well as a significant reduction in oxidation and decarburization of the material surface.
