An annular cavity is provided inside the member, a water inlet pipe communicating with the annular cavity is provided at a lower end of the annular connector, and a water outlet pipe communicating with the annular cavity is provided at an upper end of the annular connector.

Induction heating furnace without disturbance temperature measuring device , characterized in that the air blowing pipe extends into the stone

A plurality of air outlet holes are opened on the wall of the ink temperature measuring blind tube.

The induction heating furnace without disturbance temperature measuring device is characterized in that: the graphite temperature measuring blind tube

The inner wall and the convex edge of the tube are provided with an inlay groove for placing the blowing pipe and a smoke guide groove for exhausting the smoke in the pipe.

The mosaic groove and the smoke guide groove are oppositely opened. The induction heating furnace without disturbance temperature measurement device is characterized in that the number of the fixed blocks of the temperature measurement points is 4 to 8 , the fixed block of the temperature measurement points is provided with a U -shaped slot, and a plurality of the temperature measurements The point fixing blocks are evenly mounted on the upper end of the induction coil through a U -shaped slot. The induction heating furnace without disturbance temperature measuring device is characterized in that the air blowing pipe is an 11 type air blowing pipe.

Compared with the prior art, it has the following advantages:

1. It can overcome the shortcomings of poor temperature stability of the existing dual colorimetric infrared thermometer, achieve accurate temperature measurement in the induction heating furnace , and improve the processability and consistency of high-temperature treatment of carbon products.

2. The graphite temperature measurement blind tube is inserted into the heating body of the induction heating furnace . The graphite temperature measurement blind tube forms a closed channel in the induction heating furnace to block the volatile gas generated by the heating material in the induction heating furnace from entering the temperature measurement area. In addition,

The blowing tube can choose l1 type blowing tube. In order to prevent slippage, the blowing tube is embedded in the mosaic groove of the graphite temperature measurement blind tube. The end of the graphite temperature measurement blind tube is passed into the inert gas, which can blind the graphite temperature measurement. The residual gas in the tube extends from the blowing tube into the graphite to measure

The other end of the temperature blind pipe is discharged through the opening and the air outlet hole to realize the flow and discharge of the residual gas in the gradient direction.

3. The fixed blocks of multiple temperature measurement points are evenly mounted on the upper end of the induction coil in the induction heating furnace , used to fix the heating body, so that the radial distance between the induction coil and the heating body is constant, and the accurate positioning of the measured temperature is achieved. Consistency, the flange of the water-cooled temperature measurement window has a sandwich cavity structure, which enters and exits under the cooling water, is used to support the graphite temperature measurement blind pipe and lower

Graphite measures the temperature at the upper end of the blind tube.

4. It can effectively avoid the interference of smoke and dust on the dual colorimetric infrared thermometer, and realize the accurate collection of temperature data in the induction heating furnace by the dual colorimetric infrared thermometer . In addition, the mechanical device is used to manually adjust the temperature measurement to reduce To reduce the labor intensity of testers, it is not necessary to wipe the lens at the position of the temperature measurement window during the operation, which reduces the safety risk.

5. According to the characteristics of the dual colorimetric infrared thermometer, the temperature measurement device is reasonably designed, the structure is simple and easy to implement, and it can be used repeatedly, and the consistency of temperature measurement of different induction heating furnaces is ensured . The technical solution will be further described in detail below through the drawings and embodiments.
