Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung und ein Verfahren zur kontinuierlichen Stahlerzeugung und metallurgischen Bearbeitung sowie gegebenenfalls zur kontinuierlichen Weiterverarbeitung.The present invention relates to an apparatus and a method for continuous steelmaking and metallurgical processing and optionally for continuous further processing.
Im Stand der Technik sind Stahlwerke mit elektrischen Lichtbogenöfen bekannt. Diese Lichtbogenöfen sind als Drehstromlichtbogenöfen (mit drei Schmelzelektroden) oder Gleichstromlichtbogenöfen (mit Schmelzelektroden und Bodenelektrode) ausgebildet.In the prior art, steel mills are known with electric arc furnaces. These arc furnaces are designed as three-phase arc furnaces (with three melting electrodes) or direct current arc furnaces (with melting electrodes and bottom electrode).
Das einzuschmelzende Material (Einsatzmaterial) ist üblicherweise Stahlschrott. Es gibt verschiedene Vorgehensweise, das Einsatzmaterial in den Lichtbogenofen zum Einschmelzen zu chargieren. Es ist möglich den Deckel anzuheben und den Stahl in das Ofengefäß abzuwerfen. Weiterhin sind Lösungen mit Chargiergutvorwärmern, die als Schacht ausgebildet sind, zur chargenweisen oder zur kontinuierlichen Beladung bekannt. Die Beladeöffnungen für das Ofengefäß sind dabei, sofern nicht der Deckel angehoben wird, entweder oben im Deckel oder seitlich am Ofengefäß ausgebildet.The material to be melted (feedstock) is usually steel scrap. There are several ways to charge the feed to the arc furnace for melting. It is possible to lift the lid and throw the steel into the oven jar. Furthermore, solutions with Chargiergutvorwärmern that are designed as a shaft, known for batch or continuous loading. The loading openings for the furnace vessel are, unless the lid is raised, formed either in the top of the lid or laterally on the furnace vessel.
Solche Lichtbogenöfen werden zur diskontinuierlichen oder zur kontinuierlichen Stahlerzeugung verwendet. Bei der diskontinuierlichen Stahlerzeugung wird üblicherweise eine bestimmte geschmolzenen Stahls in ein Gefäß (Pfanne) abgegossen (abgestochen). Dazu wird das Ofengefäß häufig gekippt. Es gibt auch Lösungen, bei denen ohne Kippen des Ofengefäßes der Stahl abgestochen wird. Wichtig ist es, darauf zu achten, dass keine Schlacke oder möglich wenig Schlacke beim Abstechen in die Pfanne gelangt. Ein Beispiel für eine solche herkömmliche Technologie ist in der
Im Stand der Technik wurden auch Öfen für ein kontinuierliches Einschmelzen angedacht (siehe zum Beispiel die
Aufgabe der Erfindung ist es, eine verbesserte Vorrichtung und ein verbessertes Verfahren zum kontinuierlichen Einschmelzen und metallurgischen Behandeln sowie gegebenenfalls zum Weiterverarbeiten von Stahl anzugeben.The object of the invention is to provide an improved apparatus and an improved method for continuous melting and metallurgical treatment and optionally for further processing of steel.
Diese Aufgabe wird gelöst durch eine Vorrichtung nach Anspruch 1 bzw. ein Verfahren nach Anspruch 5.This object is achieved by a device according to claim 1 or a method according to claim 5.
Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Further developments of the invention are specified in the subclaims.
Es werden zahlreiche, unabhängig voneinander und in Kombination miteinander wirkende Merkmale und Vorgehensweisen gelehrt. Das Zuführen des Einsatzmaterials durch eine seitliche Öffnung in das Ofengefäß, vorteilhafterweise mittels eines Schiebers, führt zu der Möglichkeit des kontinuierlichen Einschmelzens von unsortiertem Stahlschrott ohne die Gefahr einer Beschädigung der Elektroden. Das Überleiten der Schmelze durch einen kontinuierlichen, schlackefreien Abstich wie einen Syphon ermöglicht das kontinuierliche Einschmelzen ohne die Notwendigkeit des Abstichs und/oder eines Kippens des Ofengefäßes. Das Vorsehen einer länglichen Wanne mit Elektroden ermöglicht die kontinuierliche metallurgische Behandlung und Temperatureinstellung des aus dem Einschmelzgefäß übergeleiteten Stahlbades. Der direkte Anschluss einer Weiterbearbeitungsvorrichtung wie einer Stranggussanlage an den Ablauf dieser länglichen Wanne ermöglicht ein kontinuierliches Weiterverarbeiten.It teaches numerous features and procedures that work independently and in combination with each other. The feeding of the feedstock through a lateral opening in the furnace vessel, advantageously by means of a slide, leads to the possibility of continuous melting of unsorted steel scrap without the risk of damaging the electrodes. Passing the melt through a continuous, slag-free tapping such as a siphon allows for continuous melting without the need for tapping and / or tilting of the furnace vessel. The provision of an elongated trough with electrodes enables the continuous metallurgical treatment and temperature adjustment of the steel bath passed from the fusing vessel. The direct connection of a further processing device such as a continuous casting plant to the outlet of this elongated trough allows a continuous further processing.
