Induksion isitish pechi ignabargni qizdirganda, joriy chastotani qanday tanlash mumkin?

Induksion isitish pechi ignabargni qizdirganda joriy chastotani tanlash jadvalda ko’rsatilgan

Po’lat ignabargli diatermiya bo’lganda oqim chastotasini tanlash

Bo’sh diametri /mm	Joriy chastota/Gts
Bo’sh diametri /mm	Kuri nuqtasi ostida	Kuri nuqtasidan yuqori
6 -12	3000	450000
12-25	960	10000
25-38	960	3000 -10000
38-50	60	3000
50 -150	60	960
> 150	60	60

Jadvaldan ko’rinib turibdiki, bo’sh joy Kyuri nuqtasidan pastroq haroratda qizdirilganda, oqimning sayoz kirib borishi tufayli chastota Kury nuqtasining o’ndan biriga to’g’ri kelishi mumkin. Agar ikkita chastotali isitish ishlatilsa, masalan, kompyuter po’lat panjaralari, Kyuri nuqtasidan oldin va keyin Har xil tok chastotalaridan foydalanish isitish samaradorligini oshirishi mumkin. Yaqinda katta diametrli ignabargli materiallarni isitish uchun 30 Gts chastotali konversion quvvat manbai ishlab chiqildi.
