Description
Schutzrohr für TemperaturmeßeinrichtungProtection tube for temperature measuring device
Zur Messung von Temperaturen in Schmelzen verwendet man unter anderem Thermoelemente und ähnliche Einrichtungen die mittels Schutzrohren in die Schmelze eingebracht werden.To measure temperatures in melts, one uses, among other things Thermocouples and similar devices that are introduced into the melt by means of protective tubes.
Dabei treten allerdings besondere Schwierigkeiten auf. Die bis dato verwendeten Graphitrohre halten den durch die Temperaturunterschiede zwischen Schmelze und Atmosphäre bedingten Spannungen nicht stand, und sind nach sehr kurzer Zeit unbrauchbar. Weiterhin sind sie für den rauhen Gießereibetrieb wegen ihrer Zerbrechlichkeit schlecht geeignet» Aus diesem Grunde hat man ein Eisenrohr mit einer Keramikschicht versehen. Dieses Verfahren wurde in Amerika angewandt, brachte aber nicht den gewünschten Erfolg, da Stahl und Keramik einen anderen Ausdehnungskoeffizienten haben und durch die gerissene Keramikschicht das Eisen in die Schmelze wandertee However, particular difficulties arise here. The graphite tubes used to date do not withstand the stresses caused by the temperature differences between the melt and the atmosphere and are unusable after a very short time. Furthermore, because of their fragility, they are unsuitable for rough foundry operations. For this reason, an iron pipe was provided with a ceramic layer. This method was used in America, but did not bring the desired success, since steel and ceramic have a different coefficient of expansion and the iron migrated into the melt through the cracked ceramic layer e
Der Erfinder hat es sich nun zur Aufgabe gemacht, diese oben erwähnten Nachteile durch eine sinnfällige Konstruktion auszuschalten. Aus diesem Grunde wird in an sich bekannter Weise eine feuerfeste chemische Umhüllung auf ein Metallrohr aufgebracht und durch Wärmeeinwirkung eine gute Haftverbindung hergestellt. Diese Umhüllung wird zur Ausgleichung der Temperaturdehnungen mit einer weiteren aus Glassträngen oder -geweben bestehenden Schicht umgeben. Die Außenhaut besteht wieder aus dem Material der mit dem Metallrohr direkt in Berührung stehenden Schicht. Die Lage der Schicht kann entsprechend varriert werden. Die Kombination Eisenrohr, feuerfeste chemische Umhüllung, Glasgewebe, bzw. Glasstrangbeschichtung bringt eine wesentlich längere Haltbarkeit und Verwendungsfähigkeit des SchutzrohreseThe inventor has now set himself the task of these above-mentioned Eliminate disadvantages through a logical construction. For this reason, a fire-resistant chemical coating is applied to a metal pipe in a manner known per se and, by the action of heat, a good adhesive bond established. This envelope is used to compensate for the temperature expansions with another one made of glass strands or fabrics Surrounding layer. The outer skin again consists of the material of the layer that is in direct contact with the metal pipe. The location of the Layer can be varied accordingly. The combination iron pipe, refractory chemical coating, glass fabric, or glass strand coating brings a significantly longer shelf life and usability of the protective tube
