  Verfahren   zur Herstellung von Stahl uder Flusseisen im Martinofen   aus Alteisen (Schrott) und gepulvertem festem Kohlenstoff. 



   Das Stammpatent betrifft ein Verfahren zur Herstellung von Stahl oder   Flusseisen.   wobei gepulverter fester Kohlenstoff, z. B. Koks, zu unterst auf die Herdsohle aufgetragen wird, der oberflächlich angefeuchtet wurde, um an der nach oben zeigenden feuchten Oberfläche der Kohlungsmittelschicht durch die Ofenwärme eine Decke bzw. eine Sicherungkruste zu erzielen, welche den darunter befindlichen Kohlenstoff schützt. Auf die Kohlungsmittelschicht wird das Altmaterial aufgetragen und dasselbe eingeschmolzen. 



   Gemäss vorliegender Erfindung wird dieses Verfahren dahin ausgebildet, dass durch wiederholtes Mahlen und Quetschen eine ungemein grosse Feinheit des Koksstaubes erzielt wird, so dass derselbe in einer Feinheit von ungefähr 3000 bis 5000 Öffnungen pro Quadratzentimeter eines Siebes und noch feiner zur Anwendung kommt, wodurch die Herstellung vorzüglichsten   Qualitätsstahles   ohne irgend welchen Roheisenzusatz erzielt wird. Je feinmaschiger das Sieb ist, welches der Koksstaub vor seiner Verwendung passiert, desto günstiger gestaltet sich die Durchführung des Verfahrens.

  Process for the production of steel or mild iron in the Martin furnace from scrap iron and powdered solid carbon.



   The parent patent relates to a process for the production of steel or mild iron. wherein powdered solid carbon, e.g. B. coke is applied to the bottom of the hearth, which was moistened on the surface in order to achieve a cover or a backup crust on the upward-facing moist surface of the carbon layer through the furnace heat, which protects the carbon below. The old material is applied to the carbon middle layer and melted down.



   According to the present invention, this method is designed in such a way that an extremely high fineness of the coke dust is achieved by repeated grinding and squeezing, so that the same is used in a fineness of approximately 3000 to 5000 openings per square centimeter of a sieve and even finer, whereby the production exquisite quality steel is achieved without any addition of cast iron. The finer-meshed the sieve through which the coke dust passes before it is used, the cheaper it is to carry out the process.
