VERFAHREN ZUM VORWÄRMEN UND ZUM KONTINUIERLICHEN EINBRINGEN EINER CHARGE IN EINEN ELEKTROLICHTBOGENOFEN |
摘要 |
<p>The invention relates to a method and device for pre-heating a charge for an electric arc furnace (EAF) (1). The reoxidation on pre-heating HBI and DRI in the EAF (1) is avoided, whereby the pre-heating of the charge is achieved by means of the flue-gas from the EAF (1), flowing co-current with the direction of transport of the charge and by controlling the oxygen content of the flue gases. A vertical top-charging pre-heating shaft is fitted in the vicinity of the EAF (1), which comprises a heavy transporter for the charge. The upper end (3) thereof is connected to the EAF (1) and the lower end thereof (13) is flow connected to a source of reduced pressure (2) and which also comprises at least one gas burner (22), with controllable flue-gas oxygen content.</p> |
