Description

Verfahren zur Herstellung von Schweißeisen bzw. -stahl Die Erfindung betrifft die Herstellung von Schweißeisen bzw. -stahl nach dem Astonverfahren, nach welchem bekanntlich flüssiger Stahl in ein Schlackenbad eingeführt wird.Process for the production of welding iron or steel. The invention relates to the production of welding iron or steel according to the Aston process which, as is known, liquid steel is introduced into a slag bath.

Bei Durchführung des Astonverfahrens kann ein bedeutend größerer Ball (Luppe) als bei dem alten Handpuddelverfahren hergestellt werden. Die Erfindung besteht nun darin, daß beim Eingießen des geschmolzenen Stahles in das Schlackenbad der schmelzflüssige Stahl bzw. das Eisen über die Oberfläche des Schlackenbades verteilt in dieses eingegossen wird, anstatt den Strahl, wie früher üblich, auf eine einzige Stelle zu richten. Verfährt man nämlich in der üblichen Weise, so entsteht in der flüssigen Schlacke eine örtlich heiße Zone, welche die gute Granulierung des Stahles und die erforderliche Reaktion zwischen Stahl und Schlacke stört. Auch erfolgt beim üblichen Verfahren die Berührung zwischen Metall und Schlacke nicht unter Einhaltung der erforderlichen Temperaturunterschiede zwischen Stahl- und Schlackenbad. Verfährt man aber erfindungsgemäß, indem man den heißen Stahl- bzw. Eisenstrahl hin und her und rundherum über das Bad verteilt, so erhält man ein Erzeugnis, das im wesentlichen durch und durch gleichmäßig granuliertes Gefüge aufweist.When performing the Aston Procedure, a significantly larger ball (Luppe) than with the old hand puddling process. The invention is now that when pouring the molten steel into the slag bath the molten steel or iron over the surface of the slag bath is poured into this instead of the jet, as was customary in the past to judge a single body. If one proceeds in the usual way, it arises a local hot zone in the liquid slag, which is good for granulation of the steel and interferes with the required reaction between steel and slag. Even In the usual process, there is no contact between metal and slag in compliance with the required temperature differences between steel and slag bath. However, if you proceed according to the invention by using the hot steel or iron beam Distributed back and forth and all around over the bathroom, you get a product that essentially has a uniformly granulated structure through and through.

Besonders vorteilhaft ist es, dieses Verfahren zur Herstellung eines ebenfalls von der Erfinderin vorgeschlagenen länglichen Metallballes anzuwenden, indem man das Eingießen vorzugsweise unter Hinundherbewegung des Strahles längs der längeren Achse eines rechteckigen Behälters vornimmt.It is particularly advantageous to use this method for producing a also to use elongated metal ball proposed by the inventor, by making the pouring preferably with reciprocation of the jet lengthways the longer axis of a rectangular container.
