Abstract

POSTUPAK ULTRABRZE TERMIČKE OBRADE ELEKTRO ČELIKA SA ORIJENISANOM STRUKTUROM, u kome se čelik, koji sadrži manje od 6,5% silicijuma, podvrgava visokim temperaturama, a dobijena traka elektro čelika ima sekundarna zrna redukovane veličine i poboljšane gubitke u jezgru, tako da izdržava otpuštanje unutrašnjih napona bez znatnije promene magnetskih svojstava, naznačen time, što se hladno valjana traka podvrgava ultrabrzom odgrevanju brzinom zagrevanja od preko 100В°C/sek do temperature više od 675В°C, dekarburizaciji i finalnom visokotemperaturnom odgrevanju za sekundarni rast zrna. Prijava sadrži 6 zavisnih zahteva.
