Description
Die Erfindung liegt auf dem Gebiet des Niederdruck-Gießverfahrens. Sie betrifft die Herstellung von Stahlhalbzeugen aus Stahlschmelze. Sie löst die Aufgabe, Vorblöcke, Vorbrammen und Knüppel mit einwandfreier Oberfläche, die keiner Nachbearbeitung bedarf und unmittelbar walzfähig ist, in einem Gießvorgang herzustellen. Die Gußstücke können unmittelbar, also ohne Zwischenbehandlung zu flachen Platinen, Blechen und Hohlblöcken gewalzt oder gepreßt werden, so daß sich die bisher übliche Gieß- ίο blockherstellung und Tiefofenlagerung ebenso erübrigen wie ein Vorwalzen von Ausgangsblöcken sowie deren Abdrehen bzw. Abhobeln.The invention is in the field of low pressure casting. It concerns the production of steel semi-finished products from molten steel. She solves the task Blooms, pre-slabs and billets with a perfect surface that do not require post-processing needs and is immediately rollable to produce in one casting process. The castings can be thus rolled or pressed to flat blanks, sheets and hollow blocks without intermediate treatment so that the previously customary casting ίο block production and deep furnace storage are also unnecessary such as pre-rolling starting blocks as well as turning or planing them off.
Das Niederdruck-Gießverfahren zur Herstellung von Stahlformguß ist bekannt. Hierzu hat sich eine Stahlschmelze unter Luftabschluß führende Gießpfanne bzw. ein Schmelzgefäß bewährt, das für den Durchtritt der Stahlschmelze luftdicht mit dem Einguß einer gestreckten geschlossenen und bis auf einen oben angeordneten Steiger luftdichten Form verbunden ist. Diese Form wird durch Beaufschlagung der Gießpfanne unter Druck gefüllt. Der Einguß ist ebenfalls luftdicht verschlossen. Im Bereich des Eingusses werden die Gußstücke mit hoher Geschwindigkeit abgekühlt. Nach dem Erstarren werden die Gußstücke aus der Form gelöst unter Abschneiden der im Bereich des Steigers und des Eingusses !unterlassenen, mit groben Lunkereinschlüssen behafteten Gußenden. Als Verschlußstücke aus kühlendem bzw. abschreckendem Stoff hat sich besonders Graphit bewährt. The low-pressure casting process for producing cast steel is known. For this purpose a Steel melt under the exclusion of air leading pouring ladle or a melting vessel proven, which for the Passage of the steel melt airtight with the pouring of a stretched closed and except for one above arranged riser is connected to airtight form. This form is created by applying the Ladle filled under pressure. The sprue is also hermetically sealed. In the area of the sprue the castings are cooled at high speed. After solidification, the castings are detached from the mold by cutting off those in the area of the riser and the sprue! Cast ends afflicted with coarse voids. As sealing pieces made of cooling resp. Graphite in particular has proven itself as a deterrent.
Die Erfindung bezieht sich auf die Anwendung dieses Niederdruck-Gießverfahrens auf das Gießen von Vorblöcken, Vorbrammen, Knüppeln oder Platinen. Hierzu wird bei einem Behälter für die Stahlschmelze mit einer gestreckten Verbindung zwischen dem Behälter und dem Einguß an einem Ende einer geschlossenen langgestreckten Gießform aus kühlendem Stoff und einem Steiger zur Sicherung der Dichtspeisung des Gußstückes in seinem inneren Bereich die Längsachse der gestreckten geschlossenen Form zur Waagerechten mit einer geringeren Neigung als 90° ausgebildet. The invention relates to the application of this low pressure casting process to the casting of Blooms, pre-slabs, billets or blanks. This is done with a container for the molten steel with an elongated connection between the container and the sprue at one end of a closed one elongated casting mold made of cooling material and a riser to secure the sealing feed of the casting in its inner area the longitudinal axis of the stretched closed form to the horizontal formed with a lower inclination than 90 °.
Durch die Anwendung des Niederdruck-Gießverfahrens und die Vorrichtung zur Herstellung von Blockgußstücken werden Gußstücke mit einer glatten Oberfläche erzeugt, die innerlich frei von Hohl- und Lunkerstellen sowie Rissen sind. Diese günstige Ausbildung wird auch auf den Endoberflächen der Gußstücke erreicht. Bei langgestreckten Gußstücken sind deren Stirnseiten ebenfalls frei von Hohlstellen. Daher können die nach der Erfindung erzeugten Blockgußstücke unmittelbar zu handelsfähigen Erzeugnissen fertig gewalzt werden.By using the low pressure casting process and the device for the production of Block castings are castings with a smooth surface that is internally free of hollow and There are cavities and cracks. This favorable design is also applied to the end surfaces of the castings achieved. In the case of elongated castings, their end faces are also free of voids. Therefore the block castings produced according to the invention can be converted directly into marketable products be finish-rolled.
In der Praxis wurden schon Knüppel und Eisenblechbrammen gegossen bei einem Metallzufluß von etwa 29,45 kg/Sek. Diese Knüppel waren ungefähr 7,50 m lang und hatten einen quadratischen Querschnitt von höchstens 8,1 cm Seitenlänge. Die obere und untere Kastenhälfte, die die Gießform bilden, in der derartige Knüppel gegossen wurden, waren wie üblich aus Graphitblöcken gebildet, die an ihren aufeinanderliegenden Oberflächen maschinell bearbeitet waren.In practice billets and sheet iron slabs have already been cast with a metal inflow of about 29.45 kg / sec. These billets were approximately 7.50 m long and had a square cross-section with a maximum side length of 8.1 cm. The upper and lower box halves that form the mold, in which such billets were cast were, as usual, made of graphite blocks attached to their superimposed surfaces were machined.
