Temperature Simulation

  • Tools: PHOENICS / JMAG
  • Features: Cost Reduction / Rapid Validation

By understanding heat transfer behavior, temperature distribution, and the impact of heating conditions in advance, simulation reduces the number of physical experiments and helps you reach optimal conditions faster.

Furnace Thermal Analysis

The hot zone configuration inside the furnace is designed on a computer, and the required temperature distribution is simulated. Existing hot zones can also be analyzed, enabling prediction of internal temperature environments that are difficult to measure.

Continuous Heat Treatment Furnace Analysis

Using JMAG, a wide range of electromagnetic induction heating scenarios can be simulated. In addition to power supply design parameters (power, inductance, load resistance), the temperature distribution of the workpiece can also be analyzed.

Other Case Studies (High-Frequency Coil Simulation)

By modeling the combination of high-frequency heating coils and furnaces, heating efficiency and temperature uniformity can be analyzed. This enables optimization of coil configurations.
