Radiant panel thermometer comes the check-out console temperature by detecting the heat radiation of band steel, at first will determine the radiation coefficient with steel before the check-out console temperature, and detected heat radiation is converted to belt steel temperature by radiation coefficient.Its conversion formula is:
T＝ε/λ，
Wherein: T is the plate temperature, and ε is heat radiation, and λ is a radiation coefficient.
For the band steel of the different steel grades and the trade mark, and the band steel of different production line production, radiation coefficient all can be different, and therefore the verification of plate temperature meter will be carried out in every kind of band steel capital, determines radiation coefficient.Because Horizontal Continuous Furnace is in heating process, the band steel is operation continuously in airtight body of heater, is the blanket gas of high temperature, Gao Qing in the stove, can't open the actual temperature that body of heater detects the band steel.Therefore the actual temperature that how to detect the band steel exactly is to determine the key of radiation coefficient.
At present the method that adopts be allow the band steel in stove with after minimum speed stable operation a period of time, come verification plate temperature in the furnace temperature detected value as the plate temperature of band steel.This method of calibration error is big, check-verifying period is long, can't guarantee the accuracy of detection of plate temperature meter and the control accuracy of plate temperature.
The utility model content
The purpose of this utility model is to provide a kind of radiant panel thermometer calibration equipment of Horizontal Continuous Furnace, this device can be measured the actual temperature of band steel immediately in the process of the normal operation of band steel, determine the radiation coefficient of band steel, it is simple in structure, and is easy for operation.
The utility model is achieved in that
A kind of radiant panel thermometer calibration equipment of Horizontal Continuous Furnace, it is characterized in that: described calibration equipment comprises: temperature-detecting device, packoff and sleeve pipe, in the layer of anti-material of horizontal annealing furnace furnace bottom and furnace bottom, have the duct that communicates, casing pipe sleeve is loaded on the duct inwall, the sleeve pipe upper end communicates with the annealing furnace inner chamber, and packoff is equipped with in the sleeve pipe lower end; Temperature-detecting device comprises: thermopair, display device, and thermopair is set in the sleeve pipe by packoff, and the thermopair lower end links to each other with display device by lead.
Scale is equipped with on described thermopair surface.
Described packoff comprises ball valve and handle, and the ball valve upper end is connected with the sleeve pipe lower end, and handle places the ball valve side.
The utility model has the duct in bottom of furnace body and the furnace bottom layer of anti-the material, the temperature thermocouple passing hole channel enters body of heater, owing to scale is housed on the temperature thermocouple surface, just can on scale, carry out mark according to different model band steel, prevent that temperature thermocouple will be with steel jack-up to band steel thermometric the time, cause temperature thermocouple and band steel impaired, influence measurement result.Simultaneously, temperature thermocouple shows instant detected belt steel temperature information by coupled display device, change by formula T=ε/λ again, accurately calculate the value of radiation coefficient λ, thus quick, accurate verification radiant panel thermometer, it is simple in structure, and is easy for operation.

Among the figure: 1 temperature thermocouple, 2 sleeve pipes, 3 ball valves, 4 handles, 5 scales, 6 leads, 7 display device, 8 bodies of heater, 9 layers of anti-material the, 10 furnace rollers, 11 band steel, 12 radiant panel thermometers.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of radiant panel thermometer calibration equipment of Horizontal Continuous Furnace comprises temperature-detecting device, packoff and sleeve pipe 2, and wherein temperature-detecting device comprises: temperature thermocouple 1, lead 6 and display device 7; Packoff comprises: ball valve 3 and handle 4.
In the layer of anti-material the 9 of horizontal annealing furnace body of heater 8 bottoms and furnace bottom, have the duct that communicates, sleeve pipe 2 is set in the duct inwall.Sleeve pipe 2 upper ends communicate with the annealing furnace inner chamber, and the upper end open place is corresponding with radiant panel thermometer 12; Sleeve pipe 2 lower ends are connected with ball valve 3 upper ends, in ball valve 3 sides one handle 4 are installed, by the switching of rotary handle 4 may command ball valves 3.Temperature thermocouple 1 is set in the sleeve pipe 2 by ball valve 3, and temperature thermocouple 1 can move by easy on and off in sleeve pipe 2.On temperature thermocouple 1 surface scale 5 is housed, the lower end of temperature thermocouple 1 links to each other with display device 7 by lead 6.
The utility model is work like this:
Under the situation of cold conditions, detect the distance of band steel 11 earlier, and on the scale 5 of temperature thermocouple 1, carry out mark to body of heater 8 bottoms.Because under certain furnace roller 10 spacings and tension force situation, band steel 11 in the horizontal annealing furnace is relatively-stationary to the distance of body of heater 8 bottoms, do like this and can avoid temperature thermocouple 1 band steel 11 jack-up when detection band steel 11 real-time temperatures, cause thermopair 1 and band steel 11 impaired, influence measurement result.
