Measuring temperature of the atmosphere in the steelmaking furnace
Original language description
The paper presents a measurement of temperature in a steelmaking furnace with an oxygen refining process, specifically in the tandem furnace. Knowledge of the temperature is important for optimizing the manufacturing process and extending of the life cycle of the inner furnace lining. Conditions in the furnace are very demanding; the temperature may temporarily exceed 2000oC and exhibits changes of 60oC.s-1. The atmosphere in the furnace is mainly oxidizing and its chemical composition is very variable.In the atmosphere there are also present liquid and solid compounds which act chemically and abrasively on the lining and on the sensor. These conditions make it impossible to use a suction pyrometer, contactless optical or acoustic measurement methods.It was decided to use a thermocouple in a protective tube. The sensor was inserted into the furnace through a steel bushing with water cooling. For the first measurement the type-B thermocouple in Al2O3 protective tube inside an outer sh
