Vorrichtung und Verfahren zur dynamischen Steuerung eines Brenners in einem Lichtbogenofen

摘要

Apparatus for dynamic monitoring of the combustion of a burner (8) emitting a flame (9) through an aperture (8') at one end located above a bath of molten metal (3) covered by a charge of metal scrap (5) uses a contact-less arrangement situated outside the arc furnace to estimate the distance between the end of the burner and a target formed by the adjacent layer of scrap metal. It includes a source that emits a signal, preferably in the form of a pulsed laser beam, passing through the inside the burner in the direction of the target, and a detector (11) that captures the signal reflected by the target and also passing through the burner.
