Abstract
The utility model relates to a protector for a sensor, in particular to a steel plate hot-rolled water mist-proof and anti-pollution temperature measuring device, comprising a temperature measuring probe. The utility model is characterized in that the temperature measuring probe is arranged inside a slant stainless steel bushing which is fixed on a base, the upper end opening of the stainless steel bushing has a vertical plane. The utility model has the advantages of simple structure and convenient installation, and guarantees the accuracy of the temperature measurement as well as increases the output of the hot-rolled sheet steel and improves the quality of the hot-rolled steel plate.
Description
Technical field
The utility model relates to a kind of protective device of sensor, specifically a kind of anti-pollution temperature measuring equipment of anti-water smoke of hot-rolled steel plate.
Background technology
Often need the temperature of steel plate is controlled in the hot rolling production run of steel plate, especially temp measuring system (RT2) is that the quality control of crucial measurement point and hot-rolled product is closely bound up behind the roughing mill RT2.Because the dephosphorization water under high pressure that uses in the operation of rolling, when the band steel that runs into about 1000 ℃, above the band steel, form dense water smoke immediately, surface at the band steel forms water membrane, directly disturbed temperature probe, make the detected emittance of temperature probe depart from actual value, therefore caused the skew of measurement data, to cause the RT2 temperature value measured to record temperature value than FTO before the finish rolling flying shear low regularly, reach 30 when serious---about 50 ℃, obviously be not inconsistent with reality, the observed temperature of RT2 should be higher about 30 ℃ than FTO observed temperature in theory, and the error that two-phase compares and measures reaches about 70 ℃.The error of this measurement directly has influence on the setting of finishing mill, the self study of model, and the control of thickness or the like, again because the RT2 measured temperature also is adjusting and the forecast that heating furnace burns the steel temperature, therefore whole roll line product quality and output, energy-saving and cost-reducing etc. all there is in various degree influence, cause finishing mill to set mistake when serious, cause steel scrap.All the time, infrared temperature-test sensor all is mounted in the top of the other hot-strip of roughing mill, in order to eliminate the influence of fog and band molten steel film, the installation site of temperature probe changed into by the top of milling train be installed in the milling train below (because fog is upwards to fly away, band steel lower surface can't produce moisture film), installation can effectively solve the influence to temperature probe of moisture film that the dephosphorization water under high pressure forms at surface of steel plate and the water smoke above the steel plate like this, but fall dephosphorization water after rise and fall down iron scale and still can pollute probe from the steel plate lower surface, therefore, the anti-pollution temperature measuring equipment of anti-water smoke of inventing a kind of new hot-rolled steel plate is highly profitable.This device both can guarantee that probe can effectively survey the steel plate emittance, can prevent that again water smoke and steel plate lower surface from falling dephosphorization water down and iron scale after rise to the pollution of temperature probe, reaches following technique effect: 1) RT2 point for measuring temperature maintenance steady state (SS).2) the RT2 temperature measurement error should be less than 1%.3) stop the steel scrap and the quality accident that cause because of the RT2 temperature measurement error.
The utility model content
Technical problem to be solved in the utility model is the defective that exists at existing product, and a kind of anti-pollution temperature measuring equipment of anti-water smoke of hot-rolled steel plate is provided, and it can guarantee the accuracy of thermometric.
The technical solution of the utility model is achieved in that it comprises temperature probe, is characterized in that: temperature probe is contained in the stainless steel sleeve pipe of an inclination, and the stainless steel sleeve pipe is fixed on the base, and the upper port of stainless steel sleeve pipe is a vertical plane.Angle between described stainless steel sleeve pipe and the base is 60 °≤a＜90 °, has so both guaranteed that temperature probe surveyed the emittance of steel plate, and the dephosphorization water of falling can flow down along stainless steel sleeve pipe skewed surface again, can not enter stainless steel sleeve pipe internal contamination temperature probe.
The utlity model has advantage simple in structure, easy for installation, it can guarantee the accuracy of thermometric, has improved the output and the quality of hot-rolled steel plate.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
As shown in Figure 1, the utility model comprises temperature probe 1, and temperature probe 1 is contained in the stainless steel sleeve pipe 2 of an inclination, and stainless steel sleeve pipe 2 is fixed on the base 3, and the upper port 5 of stainless steel sleeve pipe 2 is a vertical plane.Angle between described stainless steel sleeve pipe 2 and the base 3 is 60 °≤a＜90 °.
Because the water under high pressure that uses dephosphorization in the operation of rolling is when the hot-strip that runs into about 1000 ℃; above hot-strip, form dense water smoke; surface at the band steel forms water membrane; the water smoke and the moisture film on the steel plate of steel plate top have directly influenced measuring accuracy; when therefore using temperature measuring equipment is installed in the below of steel plate 4; temperature probe and stainless steel pipe box with the horizontal line angle greater than 60 ° and less than 90 ° of installations; can survey the emittance of steel plate; the dephosphorization water that falls after rise flows down along the protective cover surface ramp; can not enter in the stainless steel pipe box; stainless steel pipe box bottom purges by pressure-air and has solved water smoke and the influence of iron scale to popping one's head in again, has effectively protected probe not contaminated.
