KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die Rückkühlung von schmelzflüssigem Flußeisen zur Stahlerzeugung durch Eingießen des Eisens in ein Kohlungsmittel ist bereits versucht worden.The recooling of molten iron for steelmaking by pouring of iron into a carbonic agent has already been tried. Wichtig für das Gelingen dieses Verfahrens ist eine innige Mischung des Eisens mit dem Kohlungsmittel. In dieser Beziehung" ist das früher angewendete Verfahren nach Angabe des Erfinders mangelhaft.An intimate mixture of the iron and the iron is important for the success of this process Carbonic agent. In this regard, "is the previously used method according to the statement of the inventor inadequate. ίο Das vorliegende Verfahren soll diese Mängel beseitigen und die Gewinnung eines gleichmäßigen Erzeugnisses sichern. Dies wird dadurch erzielt, daß man das flüssige Eisen in sehr dünnem Strahl in ein hohes Gefäß gießt, in welchem sich eine Kohlungsflüssigkeit, wie Teer, Öl usw., oder auch kohlend wirkende feste Stoffe befinden, welche in der Hitze flüssig werden, wie Wachs, Paraffin, Pech usw.ίο The present procedure addresses these shortcomings eliminate and ensure the production of a uniform product. This is because of this achieves that the liquid iron is poured in a very thin stream into a tall vessel, in which there is a carbonic liquid, such as tar, oil, etc., or also a carbonic liquid there are solid substances that become liquid in the heat, such as wax, paraffin, pitch etc. Jeder Tropfen flüssigen Eisens muß hierbei durch die kohlend wirkende Flüssigkeit sowie durch deren Dämpfe hindurchtreten und kommt so in die denkbar innigste Berührung mit den Kohlungsmitteln.Every drop of liquid iron has to go through the carbonic liquid as well pass through their vapors and thus come into the closest conceivable contact with the Carburizing agents. Nach dem Guß bleibt der Stahl von der überschüssigen Kohlungsflüssigkeit bedeckt, so daß die Einwirkung der atmosphärischen Luft, solange der Stahl noch flüssig ist, verhindert wird.After casting, the steel remains covered by the excess carbon dioxide, so that the action of the atmospheric air while the steel is still liquid is prevented will. Die durch die Hitze des flüssigen Metalles sich rasch entwickelnden Dämpfe umschließen und durchdringen den dünnen Metallstrahl und bewirken augenblicklich eine hochgradige Kohlung.Enclose the vapors that develop rapidly due to the heat of the liquid metal and penetrate the thin metal beam and instantly produce a high level Carbonation. Je dünner dabei der Strahl ist, mit welcn em- das Eisen vergossen wird, je höher das Gefäß ist und je mehr Kohlungsflüssigkeit zur Anwendung kommt, um so vollkommener ist die Kohlung, um so höher der Kohlenstoffgehalt des entstehenden Stahles. Durch Unterbrechung des Strahles beim Gießen lassen sich kleine, unregelmäßige, hochgekohlte Stahlgebilde erzeugen, welche sich nach Angabe des Erfinders vorzüglich zur Herstellung von Tiegelgußstahl eignen.The thinner the beam, with which em- the iron is shed, the higher the vessel is and the more carbonic liquid is used, the more perfect the carbonization, the higher the carbon content of the resulting steel. By interrupting the jet during casting, small, irregular, highly carbonized Produce steel structures which, according to the inventor, are excellent for production of crucible cast steel. Pa τ ε ν τ - A ν s ρ r u c η :Pa τ ε ν τ - A ν s ρ r uc η: Verfahren zur Kohlung von Flußeisen oder Stahl von geringem. Kohlenstoffgehalt durch Eingießen des flüssigen Metalles in eine Kohlungsmittel enthaltende Form, dadurch gekennzeichnet, daß das Metall in ein hohes Gefäß, Reiches stets die Kohlungsflüssigkeit im Überfluß enthält, in einem so dünnen Strahl gegossen wird, daß jeder Tropfen flüssigen Eisens mit den Kohlungsmitteln in innige Berührung' kommt.Method of carbonization of mild iron or steel of minor. Carbon content by pouring the liquid metal into a mold containing carbonizing agents, characterized in that the Metal in a tall vessel, rich always contains the carbonic liquid in abundance, is poured in a stream so thin that every drop of molten iron comes into intimate contact with the carbonic agents.
