Induction Heating System

This publication discusses the task of developing an induction heating system for billets made of aluminum alloy with a given limit on the permissible temperature deviation. The purpose of the work is to determine the parameters of the inductor sections and the settings of the control system to achieve a given distribution of the billet before being fed under the press. The complexity of the problem is associated with the presence of several heater sections that differ in length from the workpieces, which leads to an additional factor leading to an increase in the unevenness in the distribution of temperature in the load. The model of the electromagnetic process is built taking into account the change in resistivity in the workpieces. When searching for a more efficient calculation algorithm, a joint solution to the thermal and electromagnetic problems is considered, which allows to simplify the procedure for exchanging data between applications. This approach is very convenient for solving problems that are not connected with harsh conditions with the achievement of the final state. When modeling thermal processes, the formulation of the problem takes into account all the features associated with radiant heat transfer between extended surfaces having different temperatures, temperature dependences of the workpiece parameters, a varying heat release region due to displacement. As options for a heating system, software control and a multichannel system with control correction for temperature control at one point are considered. When simulating a multi-channel heating control system, built-in software functions were used that made it possible to form control actions for each channel and recommend the location of temperature sensors providing high-quality control of heating.

Induction Heating System

A integrated control strategy for medium-frequency (MF) induction heating system is presented in this paper. The output power regulation of MF-induction heating system used repetitive-Fuzzy PID integrated control, which can enhance the ability of the control system to withstand the parameter variations and nonlinear uncertain disturbances, and improve the dynamic characteristic of the control system; the digital phase-locked loop (DPLL) was applied to control the output frequency of MF-induction heating, which reduce the losses of switching components and improve the efficiency of the overall control system. The experimental results show that the proposed control scheme can endow the MF-induction heating power supply system with good steady state and dynamic performance and the power modulation control system can keep better precise control quality, output power adjustment quickly, high output power factor and verify the validity of the proposed integrated control strategy.

Induction Heating System

In this work, the dimensions of a furnace for melting of ferrous alloys were determined. The furnace has an electromagnetic induction heating system. In addition, the parameters of electrical power supply such as frequency and power were calculated. A 5kg cast steel mass with a density of 7.81 kg / dm3 was proposed. This corresponds to a crucible volume of 0.641 dm3. The frequency was obtained from tables, which take into account the diameter of the crucible, and its value was 1 KHz. The energy consumption was determined with the heat required to bring the steel to the temperature of 1740 K, the energy losses through the walls, bottom and top of the crucible. This value was divided between the heating time (30 minutes) and resulted in a power of 4.5 KW. The development of the calculations shows that the induction heating is an efficient process and allows a fast melting of ferrous alloys.

Induction Heating System

This paper presents potential approaches that increase the energy efficiency of an in-line induction heating system for forging of an automotive crankshaft. Both heat loss reduction and optimization of process parameters are proposed scientifically in order to minimize the energy consumption and the temperature deviation in the workpiece. We applied the numerical multiobjective optimization method in conjunction with the design of experiment (DOE), mathematical approximation with metamodel, nondominated sorting genetic algorithm (GA), and engineering data mining. The results show that using the insulating covers reduces heat by an amount equivalent to 9% of the energy stored in the heated workpiece, and approximately 5.8% of the energy can be saved by process parameter optimization.
