Step (3): infrared radiation thermometer is installed in continous way superhigh temperature graphitizing furnace fire door side, it is ensured that infrared radiation thermometer
Test height and the height of graphite block body are maintained on a horizontal line；
Step (4): continous way superhigh temperature graphitizing furnace is warming up to 2400~2800 DEG C, infrared radiation thermometer passes through measurement furnace
The temperature of graphite block body demarcates the true temperature of workspace in burner hearth in thorax；
Step (5): different location in burner hearth is demarcated by pulling Carbon fibe rope to change the relative position of graphite block body again
Temperature.
The Carbon fibe rope is the T300 crossed with 2600 DEG C of graphitization processings or the PAN base of T700 or T800 or T1000
Carbon fibe is woven into the form of three strands staggeredly class twisted shape.
The binding mode of the Carbon fibe rope and graphite block body are as follows: Carbon fibe rope is hung down for 90 ° again using positive one circle of winding
Straight one circle of winding.
The material of the graphite block body and graphite heater is equal static pressure fine grained high purity graphite.
Temperature control infrared radiation thermometer and calibration temperature are all made of double colorimetric characteristic far infrared opticals with infrared radiation thermometer and survey
Wen Yi.
The invention has the following advantages that
1, tooling and detecting instrument used in the scaling method are simple and easy to get, easy to operate；
2, workspace can be demarcated in burner hearth not only by the relative position for pulling Carbon fibe rope to change graphite block body
