Abstract

The “airtight” technology allows energy savings but hinders directprocess observation inside the vessel and information on the unmeltedscrap volume and on possible skull formation at the furnacewalls. To overcome this difficulty, a new concept is proposed, basedon mounting a camera and an endoscope inside an existing burner.This technique has been first implemented on the 155 tons DC furnacein the PROFILARBED Esch-Belval plant. Typical images of themelting phase are presented. Scrap movement mechanisms in theburner produced cavity have been displayed in real time.Operational benefits combine the appraisal of scrap basket chargingtime and anticipation of abnormal melting behaviour.
