Description

Den Gegenstand der Hauptpatentanmeldung bildet ein Verfahren zur Überwachung und Steuerung des Reaktionsablaufes beim Frischen von Roheisen durch Aufblasen von Sauerstoff auf die Schmelze, wobei die vom Reaktionsablauf abhängige elektrische Leitfähigkeit der Gasatmosphäre zwischen der elektrisch isolierten Blaslanze oder einer elektrisch isolierten Sonde und der Schmelze bestimmt und zur Steuerung des Reaktionsablaufes benutzt wird.The subject of the main patent application is a method for monitoring and controlling the course of the reaction when refining pig iron by blowing oxygen onto the melt, whereby the electrical Conductivity of the gas atmosphere between the electrically insulated blowing lance or an electrically insulated one Probe and the melt is determined and used to control the course of the reaction.

Die Hauptpatentanmeldung gibt an, daß der elekirische Widerstand der Sauerstofflanze gegen Erde möglichst hoch sein und vorzugsweise 10 000 Ω oder mehr betragen soll. Es hat sich nun gezeigt, daß auch bei weniger guter Isolation der Blaslanze das Verfahren nach der Hauptpatentanmeldung durchführbar ist. Bei einem Widerstand der Blaslanze von 10 Ω gegen Erde sind noch brauchbare Ergebnisse erzieltThe main patent application states that the electrical Resistance of the oxygen lance to earth should be as high as possible and preferably 10,000 Ω or should be more. It has now been shown that the method can also be used if the insulation of the blower lance is poor is feasible after the main patent application. With a resistance of the blowing lance of 10 Ω useful results have still been achieved against earth
