Abstract

TECHNOLOGICAL COMPETITIVENESS AND OPEX REDUCTION COMBINED WITH THE SHORTEST POSSIBLE DOWNTIME ARE THE DRIVING FORCES FOR A REVAMPING PROJECT. IN THIS PAPER A REAL CASE OF A TURN-KEY PROJECT PERFORMED BY DANIELI CENTRO COMBUSTION ON A HDGL ANNEALING FURNACE IS PRESENTED. COOLING AND SOAKING SECTIONS OF THE FURNACE HAVE BEEN MODIFIED FROM HORIZONTAL TO VERTICAL CONFIGURATION AND MOST OF THE ERECTION HAS BEEN SAFELY PERFORMED DURING NORMAL PRODUCTION WITH THE AIM OF DOWNTOWN MINIMIZATION. THE OUTCOMES OF THE PROJECT ARE PRODUCTIVITY INCREASE, NATURAL GAS CONSUMPTION REDUCTION AND PRODUCT MIX EXTENSION, PERMITTING THE CUSTOMER TO PRODUCE AHSS GRADES THANKS TO THE INCREASED SOAKING TIME IN THE RADIANT TUBE SECTION AND THE RAPID COOLING SECTION.
