Ebenso wie die Dauer einer Hochofenreise hauptsächlich von der Lebensdauer des Hochofenpanzers bestimmt wird, bestimmen die Verschleißeigenschaften der Auskleidung einer Abstichrinne deren Lebensdauer.As well as the duration of a blast furnace trip mainly from the lifetime of the blast furnace shell determines the wear characteristics of the Lining a tapping channel their life.

Zur Erhöhung der Lebensdauer einer Abstichrinne ist es bekannt, bei einer Abstichrinne für einen Schachtofen, die aus einem Trog mit einer feuerfesten, das flüssige Metall führenden Auskleidung besteht, innerhalb der feuerfesten Auskleidung hohle Kühlelemente mit Anschlußrohrleitungen für den Zu- und Abfluß von Kühlwasser vorzusehen. Diese Kühlelemente sind ihrerseits von Platten begrenzt. Parallel zu diesen Platten verlaufen weitere Kupferplatten, die aber nicht in Verbindung mit dem Kühlelement stehen. Bei diesen Kühlelementen handelt es sich um Rohrschlangen aus warmfesten Stahl, die in an sich bekannter Weise mit Ankern im Verschleißfutter der Abstichrinne fixiert sind. Es ist weiterhin bekannt, geschweißte Kupferprofile als Kühlelemente für Abstichrinnen vorzusehen.To increase the life of a tapping gutter, it is known at a tapping for a shaft furnace, which consists of a trough with a refractory, the Liquid metal leading liner exists within the refractory lining hollow cooling elements with connecting pipes for the inflow and outflow of Provide cooling water. These cooling elements are in turn limited by plates. Parallel to these plates are more copper plates, but not in connection stand with the cooling element. These cooling elements are To coils of heat-resistant steel, in a conventional manner with anchors are fixed in the wear chuck of the tapping chute. It is still known welded To provide copper profiles as cooling elements for taps.

Bei der Wandkühlung im Hochofen kommen bekanntermaßen zwei Systeme zum Einsatz. Dies sind zum einen Kühlkästen, zum anderen plattenförmige Kühlelemente, sogenannte Staves. Es gibt Kühlplattensysteme aus Kupferplatten sowie Plattenkühler aus Shäroguß. Staves kühlen flächenhaft den gesamten Hochofenpanzer und erfordern wenig Durchtritte. Grauguß-Staves sind üblicherweise Kühlelemente, in die Kühlrohre eingegossen werden.When cooling the wall in the blast furnace, it is well known that two systems are used Commitment. These are on the one hand cooling boxes, on the other plate-shaped cooling elements, so-called staves. There are cooling plate systems made of copper plates as well Plate cooler made of nodular cast iron. Staves cool areal the entire blast furnace tank and require little passage. Gray cast staves are usually cooling elements, be poured into the cooling pipes.

Kupfer-Staves sind seit mehr als 15 Jahren für die Kühlung von Hochöfen bekannt. Als Ausgangsmaterial wurden gewalzte Kupferbrammen gewählt. Das Kühlelement stellte man durch Bohren der Kühlkanäle, Anschweißen von dickwandigen Kupferrohren für die Wasserzuführung durch den Hochofenpanzer und eine geeignete mechanische Bearbeitung der Stave-Oberfläche her. Kupfer-Staves sind üblicherweise 150mm dick und gestatten bei gegebener Dicke des Mauerwerks eine Volumenvergrößerung des Hochofens von 3 bis 5%. Üblicherweise werden Kupfer-Staves bei ihrem Einbau mit Feuerfeststeinen kombiniert. Ein bekanntes Beispiel von Kupfer-Staves zeigt die DE 29 07 511 C2Copper staves have been known for more than 15 years for the cooling of blast furnaces. As starting material, rolled copper slabs were selected. The Cooling element was set by drilling the cooling channels, welding thick-walled Copper pipes for the supply of water through the blast furnace tank and a suitable mechanical machining of the stave surface ago. Copper staves are usually 150mm thick and allow for given thickness of the Masonry an increase in volume of the blast furnace from 3 to 5%. Usually Copper staves are combined with refractory bricks when installed. A well-known example of copper staves is shown in DE 29 07 511 C2

Es wird eine Haltbarkeitssteigerung des Feuerfestmaterials erreicht und somit eine Einsparung von Feuerfestmaterialkosten. Auch kann aufgrund der Kühlwirkung die Menge an kostenintensivem Feuerfestmaterial verkleinert werden. Durch die Kühlung werden verschleißbestimmende Entkohlungs- und Oxidationserscheinungen im Feuerfestmaterial unterbunden.Due to the optimal cooling effect due to the copper staves, the service life is reduced of the refractory material of a tapping channel (or pool trough) increases and the signs of wear reduced. It will increase the durability of the refractory material achieved and thus a saving of refractory material costs.
