Abstract
Two main methods of contact measurement of steel temperature are applied in industry: with help of disposable and multiple used thermotransducers. Reusable ones are fixed to the bottom of the graphite tip fixed directly on the reinforcement. Then they are able to measure the temperature of the graphite surface. Since it needs to even the graphite temperature and the temperature of the melt metal, the measuring takes some extra time. Therefore the thermotransducer is mounted in the metal for a long time. Disposable thermotransducers are placed in a quartz cylinder, which prevents the premature destruction of it. They are equipped with a thin protective metal tip that melts when the thermotransducer is penetrating the slag layer. So further the thermotransducer contacts directly with the melt metal as far as the completion of temperature measurement or destruction of the used measurement unit. The author suggests considering both these methods and tries to apply them within proposed pyrometric method. The first method is based on measuring of the surface temperature of the graphite tip in a closed space. The second one consists in measuring the temperature of melt metal that can contact with measuring unit (sensitive part of construction) after the destruction of the protective cap. The advantages of the first method are that the same probe can be used multiple times, in fact until complete destruction. The advantages of the second method consist in the direct optical contact between the metal surface and the pyrometer. The considered method is promising since it gives the possibility of contactless measurements of the temperature of melt metal within blast furnaces as well as lowering the cost of the measurement process at the metallurgy. In addition, the research envisages that the implementation of this method anticipates the subsystem for the removal of vapors from the closed protective cover that significantly affect the measurement results.
