Description
Vorrichtung zur Bestimmung der Innentemperatur von technischen Öfen, in deren Wandung der der hohen Temperatur auszusetzende temperaturempfindliche Teil fest angeordnet ist. Die Erfindung betrifft eine Vorrichtung zum Messen der Innentemperatur von technischen Ofen jeder Art, beispielsweise Martinöfen, Elektroöfen, Bessemerbirnen, Kokerei-, Hochöfen, Glasschmelzöfen u. dgl., die sich durch große Einfachheit und bedingte Sicherheit gegen Schädigungen jeder Art auszeichnet.Device for determining the internal temperature of technical furnaces, in the wall of the temperature-sensitive part to be exposed to the high temperature is firmly arranged. The invention relates to a device for measuring the internal temperature of all kinds of technical ovens, for example Martin ovens, electric ovens, Bessemer pears, Coking ovens, blast furnaces, glass melting furnaces and the like. Which are characterized by great simplicity and conditional security against damage of any kind.
Gemäß der Erfindung ist in einem in die Ofenwandung einzubauenden Klotz, der aus einem Material von ungefähr der gleichen Wärmeleitfähigkeit wie die Ofenwandung besteht, ein Thermoelement fest eingebaut und an dessen rückwärtigem Ende eine Kühlvorrichtung für die kalte Lötstelle angeordnet, die auch die Anschlußklemmen für die Meßgerätleitungen trägt.According to the invention, one is to be built into the furnace wall Block made from a material of approximately the same thermal conductivity as the Furnace wall consists, a thermocouple permanently installed and at its rear At the end of a cooling device for the cold solder joint, which also has the terminals for the measuring instrument cables.
Die Abbildung zeigt ein Ausführungsbeispiel einer Meßeinrichtung mit Therrnoelement in schematischer Darstellung im Schnitt. In dieser bedeutet I den Querschnitt eines Teiles -der Ofenwand, 2 einen zylindrischen in die Ofenwand fest eingesetzten Klotz aus feuerfester Masse, z. B. Porzellan- oder S:chamottemnisse, der Wärmeleitfähigkeit der Ofenwand entsprechend ausgewählt. 3 ist die heiße Lötstelle eines Thermoelementes, dessen Zuführungen zur Verringerung der Wärmeableitung und zur besseren Einhaltung des Abstandes von den Wänden in einem quer in dem Klotz 2 angeordneten Kanal q. parallel zur Wandfläche nach beiden Seiten geführt sind. Die Weiterleitung -der Drähte des, Therinoelementes geschieht durch achsparallele Nuten 5 am Rande des Klotzes und an der äußeren Stirnfläche. Auf diese Stirnfläche ist ein Hohlkörper 6 für Wasserkühlung aufgesetzt, um die Temperatur der Fläche selbst und der auf einer Abschlußplatte 7 angeordneten die kalten Lötstellen verkörpernden Klemmen 8 des Thermoelementes konstant zu halten. Die Leistung der Kühlung braucht, da nur geringe Wärmemengen abzuführen sind, nicht groß sein. Allerdings darf hei Verwendung solcher Kühlung der Querschnitt des Klotzes nicht zu gering sein, damit die Angaben nicht von dem etwas abweichenden Temperaturgefälle in den benachbarten Teilen der Wand beeinflußt werden.The figure shows an embodiment of a measuring device with Therrnoelement in a schematic representation in section. In this I means the Cross-section of a part of the furnace wall, 2 a cylindrical one fixed in the furnace wall used block made of refractory mass, z. B. porcelain or S: chamotte emblems, selected according to the thermal conductivity of the furnace wall. 3 is the hot soldering point a thermocouple, its leads to reduce heat dissipation and to better maintain the distance from the walls in a cross in the block 2 arranged channel q. are guided parallel to the wall surface on both sides. The forwarding of the wires of the Therino element happens through axially parallel Grooves 5 on the edge of the block and on the outer face. On this face a hollow body 6 for water cooling is attached to the temperature of the surface itself and that arranged on an end plate 7 embodying the cold solder joints Hold terminals 8 of the thermocouple constant. The performance of the cooling needs as only small amounts of heat need to be dissipated, it should not be large. However, it can be hot Using such cooling the cross-section of the block should not be too small so the information does not reflect the slightly different temperature gradient in the neighboring ones Parts of the wall are affected.
