Description
Technical field
The present invention relates to a kind of temperature measuring equipment, specifically for the contact temperature-measuring device of moving steel strip.
Background technology
Color coated steel sheet is widely used in building, household electrical appliances, automobile and other industries, and the mode that color coated band steel is being jetted by hot blast after coating in oven is toasted.Baking process to band steel heating target temperature and plate surface temperature uniformity requirement higher.Therefore the temperature recording band steel accurately produces the important guarantee of specification product.
Current baking furnace zone steel thermometric mainly adopts following several mode:
(1) after oven, radiation pyrometer is installed
The method radiation pyrometer is arranged on stove band steel exports.First radiation pyrometer temperature-measurement principle is based on Planck law, and it is comparatively large that its temperature measurement accuracy is subject to belt steel surface characteristic (chromogenic rate), and especially during band steel painting different materials, surface chromogenic rate changes again.Secondly Radiation Temperature Measurement Instrument is severe in fire door measurement environment, also result in certain influence to temperature measurement accuracy.
(2) demarcate with temperature paper
The method is affixed on moving steel strip at burner by temperature paper, takes out the warm paper of examination carry out reading at stove tail.When test point temperature is greater than a certain temperature value, heat label variable color.The maximum temperature of band steel experience is judged according to heat label color.Practical application effect shows to try warm paper and is easily subject to the impact of high-temperature furnace gas and to try warm hard copy body temperature measurement accuracy also lower, and band steel thermometric accuracy cannot be guaranteed.
(3) reed-type or roller type thermopair is adopted to measure at fire door
The method measures belt steel temperature at fire door.According to a reaction time that the mode measured is certain because thermopair has, measured value is often on the low side, and causes measured value higher owing to being with the relative velocity frictional heat of steel and measured when adopting veneer to measure.
(4) holder prescription with ingredients even in number formula is adopted to measure belt steel temperature
The method be at stove gate by thermocouple welding in band steel (be with in welding process steel static) surface, thermopair is followed band steel and is moved to the other end from body of heater one end and complete thermometric process.Because band steel time inside furnace is shorter, adopt this kind of mode measuring tape steel time inside furnace and normal process demand difference comparatively large, measurement data cannot meet the needs of process diagnosis; Thermopair and connecting line longer, in stove in operational process easily and furnace equipment collide and affect unit safety.
Therefore existing method is more difficult measures belt steel temperature accurately, is especially with the whole temperature changing process of steel in stove.
Summary of the invention
The present invention is intended to the defect overcoming prior art, and provide a kind of contact temperature-measuring device for moving steel strip, this device is placed on the band steel of motion in burner position, at stove tail, the taking-up of this device can be obtained the temperature variation data of band steel in whole stove.
In order to solve the problems of the technologies described above, the present invention is achieved in that
