Description
Verfahren zum stetigen Gießen metallischer Werkstoffe Die Erfindung betrifft ein Verfahren zum stetigen Gießen metallischer Werkstoffe, bei welchem ,der gebildete Strang nach idem 4ustritt aus der Gießform durch unmittelbare Berührung mit einem flüssigen Kühlmittel gekühlt wird. Bei Iden -bekannten Stranggneßverfahren dieser Art wendet man vorzugsweise Wasser als Kühlmittel an. Dies geschieht z. B. so, daß ;der gebildete Strang in ein Wasserbad abgesenkt wird, oder er durchwandert eine Wassertasse, oder er wird mit Wasser bespritzt. Bei der Anwendung von Spritzwasser hat sich gezeigt, daß erhebliche Wassermengen verbraucht werden, was. aus wirtschaftlichen Gründen unerwünscht ist. Dies ist vor allem darauf zurückzuführen, daß das auf den heißen Strang auftreffende Spritzwassier von :diesem weggeschlewdert wird, was wiederum Abdichtungen in der einen eder anderen Form erforderlich macht.Method for continuous casting of metallic materials The invention relates to a method for continuous casting of metallic materials, in which , the strand that is formed emerges from the casting mold through direct contact is cooled with a liquid coolant. In the case of Iden-known strand casting processes of this type, water is preferably used as the coolant. This happens e.g. B. so that; the strand formed is lowered into a water bath, or it wanders through a cup of water, or it gets splashed with water. When using spray water it has been shown that considerable amounts of water are consumed, what. from economic Reasons is undesirable. This is mainly due to the fact that the splash water hitting the hot strand: this is thrown away, which in turn Seals in one of the other forms required.
Eingeiende Untersuchungen haben ergeiben, daß das Wegschleudern des Spritzwassers von dem heißen Strang vor allem,darauf zurückzuführen ist, daß das Spritzwasser sofort beim Auftreffen idurch eine Dampfschicht vom Strang getrennt wind (Leyidenfrostsohes Phänomen) und somit in seiner Hauptmenge bar nicht zur beabsichtigten Kühlwirkung kommt.Some studies have shown that the hurling of the Splashed water from the hot strand is mainly due to the fact that the Splash water as soon as it hits it, separated from the strand by a layer of vapor wind (Leyidenfrostsohes phenomenon) and thus in its bulk bar not to the intended Cooling effect comes.
Die, Erfindung schafft hiergegen Abhilfe und ermöglicht "dieVerwendung von flüssigenKühl-mittel#n in !der Weise, ,d@aß das flüssige Kühlmittel restlos verdampft, und jede Abdichtung unnötig wird. Erfiindnzngsgemäß wird dies (dadurch erreicht, idaß das flüssige Kühlmittel als Nebel angewandt wird, was diadurch möglich ist, idaß rdas Kühlmittel durch an: sich bekannte Nebeldüsen austritt. Der Kühlmittelnebel, der auf den rot- oder weißglühenden Strang trifft, dessen Kern gegebenenfalls auch noch flüssig sein, kann, ,bringt den Strang rasch über seinen ganzen Querschnitt zur Erstarrung und kühlt ihn auf rdnegewünschte Temperatur ab, wobei ider Nebel restlos verdampft.The invention provides a remedy for this and enables "the use of liquid coolant in such a way that the liquid coolant ate completely evaporates and any sealing becomes unnecessary. According to the invention, this is achieved that the liquid coolant is used as a mist, What This makes it possible for the coolant to exit through mist nozzles known per se. The coolant mist that hits the red or white glowing strand, its core possibly also still be liquid, can, brings the strand quickly over his whole cross-section to solidify and cools it down to the desired temperature, whereby the fog evaporates completely.
Zur Herstellung des Nebels kann sowohl Wasser von Raumtemperatur als auch solches lhöherer Temperatur verwandt werden. Die Anwendung der Nebelrdüsen bietet auch die Möglichkeit, die Abkühlung rdes.gegossenen Stranges in jeder gewünschten Form abzustufen, was @insbesondere bei span.nungsrißempfindkchen, Werkstoffen von Bedeutung ist, weiil sich @dadurdh auch die Ausbildung unerwünschter Spannungszuständle leichter vermeiden läßt.Both room temperature and water can be used to produce the mist oil at a higher temperature can also be used. The application of the fog nozzles also offers the possibility of cooling the cast strand in any desired Graduating shape, which is especially true in the case of chip.nungsrißsenskchen, materials from The meaning is, because @dadurdh also develops undesirable states of tension easier to avoid.
