MEASURMENT FACILITY OF OBJECT HEATING TEMPERATURE IN IRON-AND-STEEL FURNACES AND FACILITY OPERATION MODE Russian patent published in 2009 - IPC G01K1/08 G01K7/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, to control devices of temperature conditions in chamber and pusher-type furnace of metals hot-rolling mill, and also for control of the temperature in other well-known hot mediums, allowing temperature up to 1600°C. Facility contains a body, where it is located temperature recorder, herewith body is implemented with double-layer walls, between which it is formed vacuum. Thermometeres with recorder are connected, located out of the body. The last ones are located in holes of object at different levels. Facility has a thermos - instrument container with cover, where a recorder body is located, the first bottom evaporator with tank, where an instrument container is located, and the second evaporator, closing bottom evaporator. It is provided facility operation mode, including implementation in the object of holes of different depth, location and fixation in holes of object of thermometers with measuring junction, evaporators charge by liquid coolant, for instance, water, facility assemblage, for what recorder is located in instrument container, which is installed in tank of one evaporator and tank is closed by second evaporator, then evaporators are heat-insulated, after what facility is fixed on object in run position, facility is displaced with the object in hot furnace and it is registered temperature of moving in furnace object.

EFFECT: reliability improvement of facility running and measurement accuracy of temperature, and also simplification of facility assemblage, increasing of its heat stability and expansion of workability in furnaces with increased temperature.
