Practice of Computer-Assisted Design of induction installations


Company FREAL-Ltd, St. Petersburg, produces a wide range of induction installations and power supplies and uses in it’s practice ELTA 6.0 and 2DELTA for design installations for forging, heat treating hard-facing and other technologies. To prove the efficiency and accuracy of the above mentioned software a lot of calculations and analysis of electromagnetic and thermal processes was carried out. One of them is the specially designed coils with non-uniform distribution of turns. Simulation allows improving the design of inductors, and obtaining optimal power value, heating time and frequency of HF power supplies. It is worth to mention that the programs are very useful for matching coils and generators with different layout of the power supplying circuits. Presentation is illustrated by description of some induction installations designed and produced by FREAL-Ltd using ELTA and 2DELTA. (Full text)
