Temperature measuring device for continuous coating process of steel strip

The present invention relates to a temperature measuring device, and more particularly to a temperature measuring device for a continuous coating process of a steel strip.

The temperature control of the continuous coating process of the steel strip is good for the quality of the coating film.

Due to the continuous coating process speed of steel strips up to 100 meters / min (m / min), it is difficult to directly measure the temperature of the steel strip. One of the current methods used by the industry to measure the temperature of the strip is to use temperature stickers. The surface of the steel strip is used to detect the highest temperature in the process, but this method cannot respond to the temperature of a certain fixed position, and the temperature sticker is highly disturbed by the furnace temperature, and cannot reliably react to a reasonable temperature.

Another method used by the industry to measure the temperature of the steel strip is to use the infrared thermometer to output infrared rays to the steel strip for temperature measurement. However, because the infrared thermometer is greatly affected by environmental factors, other direct tests are required. Wen thought it was corrected.

Therefore, the object of the present invention is to provide a temperature measuring device for a continuous coating process of a steel strip, which can stably contact a fast moving steel strip for direct temperature measurement, and is corrected as a production line indirect thermometer. Use.

Therefore, the novel temperature measuring device for the continuous coating process of steel strips The utility model comprises a supporting piece, an adjusting unit, a thermocouple unit, a holding unit and a display unit. The support piece is made of a high temperature resistant flexible material and has a contact portion for contacting the steel strip, a connecting portion with respect to the contact portion, and a notch formed at the contact portion. The adjusting unit is connected to the connecting portion of the supporting piece, and can adjust an angle such that the contact portion of the supporting piece is in flat contact with the steel strip. The thermocouple unit is disposed on the support piece and has a measuring end. The measuring end of the thermocouple unit protrudes from the notch of the supporting piece and gently contacts the steel strip for measuring the steel strip temperature. The grip unit is coupled to the adjustment unit and extends away from the support sheet. The display unit is electrically connected to the thermocouple unit and used to display the measured temperature value of the steel strip.

The effect of the novel is that it can be stably contacted in fast moving The steel strip is used for direct temperature measurement to overcome the problem of rapid movement and sloshing of the steel strip, and the measuring end of the thermocouple unit is extended in the notch of the supporting piece to stably contact the fast moving steel strip. Direct temperature measurement can slow down the high-speed friction heat generation and heat storage interference at the measurement point.

Other features and effects of the present invention will be apparent from the following description of the drawings. FIG. 1 is a schematic view showing an embodiment of the present invention for a temperature measuring device for a continuous coating process of a steel strip; Figure 2 is a schematic view showing the use of the embodiment; Fig. 3 is a schematic view showing the use of another angle, and Fig. 2 is explained.

Referring to FIG. 1 , an embodiment of a temperature measuring device for a continuous coating process of a steel strip comprises a supporting piece 1 , an adjusting unit 2 , a thermocouple unit 3 , a holding unit 4 , and a display unit 5.

The support sheet 1 is made of a high temperature resistant flexible material and has a contact portion 11, a connecting portion 12 with respect to the contact portion 11, and a notch 13 formed in the contact portion 11.

The adjusting unit 2 is a bent metal sheet body, and one end thereof is connected to the connecting portion 12 of the supporting piece 1.

The thermocouple unit 3 includes a thermocouple wire 31, a thermocouple connector assembly 32, and a compensation wire 33 coupled to the thermocouple connector assembly 32. The thermocouple wire 31 is attached to a surface of the support sheet 1 and extends to a surface of the adjustment unit 2. The thermocouple wire 31 has an engagement end 311 connected to the thermocouple joint assembly 32, and a reverse The measuring end 312 of the engaging end 311 protrudes from the notch 13 of the supporting piece 1 . The thermocouple connector assembly 32 includes a male connector 321 connected to the engagement end 311 of the thermocouple wire 31, and a female connector 322 that can be coupled to the male connector 321 and connected to the compensation wire 33. The positions of 321 and female connector 322 can also be reversed.

The holding unit 4 is connected to the adjusting unit 2 and extends away from the supporting piece 1 and is used for holding by a person.

Specifically, in the embodiment, the adjusting unit 2 and the connecting portion 12 of the supporting piece 1 and the adjusting unit 2 and the holding portion The connection between the units 4 is screwed and bolted by a plurality of screws 6, but it is not limited thereto. For example, it may be riveted by rivets or the like.

In addition, the display unit 5 is a temperature display, and the compensation guide The line 33 is inserted into the display unit 5 such that the measurement signal of the thermocouple wire 31 of the thermocouple unit 3 can be transmitted to the display unit 5 via the compensation wire 33 for display by the display unit 5.

Referring to Figures 1, 2, and 3, in use, the person only needs to use the hand 8 Holding the holding unit 4 of the temperature measuring device, and contacting the supporting piece 1 with the surface of a moving steel strip 7, by the design of the curved metal piece by the adjusting unit 2, the personnel only need to be slightly more The adjusting unit 2 can be elastically deformed by applying a force, so that the contact portion 11 of the supporting piece 1 can be completely flat and gently contacted with the steel strip 7 while the measuring end 312 of the thermocouple wire 31 is only partially extended. The gap 13 of the support piece 1 enables the temperature measuring device to stably contact the fast moving steel strip 7 for direct temperature measurement, and the measurement signal of the thermocouple wire 31 can be transmitted to the display via the compensation wire 33. The unit 5 displays the measured temperature value of the steel strip 7 by the display unit 5, so that the problem of rapid movement and sloshing of the steel strip 7 can be overcome, and the high-speed friction heat generation of the measuring point can be slowed down and the heat storage can be eliminated. In addition, since the support sheet 1 is made of a high temperature resistant flexible material, the surface of the steel strip 7 can be gently touched during the temperature measurement without damaging the coating on the surface of the steel strip 7.

In summary, the present invention is applied to the continuous coating process of steel strip 7 With the above-mentioned structural design, the temperature measuring device can stably contact the steel strip 7 for direct temperature measurement, and can overcome the problem of rapid movement and shaking of the steel strip 7, so that the measured temperature is more accurate. And the support piece 1 made of high temperature resistant soft coffin During the temperature measurement process, only the surface of the steel strip 7 is gently touched, so that the coating on the surface of the steel strip 7 is not damaged during the temperature measurement.
