Description

1308182 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for burying a temperature measuring line, in particular to a method for measuring the temperature distribution change when the hollow tube force σ heat is closed Temperature line burying method. [Prior Art]

The method of manufacturing alloy tubes in the industry is to fill a quantitative alloy material source (for example, alloy powder, alloy block) into a hollow tube ι (shown in the industry as carbon steel back pipe) as shown in Figure i. The chamber 102 is heated, and the hollow tube 100 is heated and the hollow tube 100 is rotated in the same direction around its own axis 1〇1 so that the alloy material source is uniformly melted, and then the temperature is lowered, and the alloy material source is formed accordingly. The chamber 102 is in the form of a predetermined tube state alloy tube. The heating temperature between π and the π can make the alloy material source melt sufficiently to form a uniform and dense alloy tube. However, when the heating temperature is excessive, the element of the medium 100 is diffused, and the material is deteriorated. Therefore, in order to manufacture a better quality alloy tube, it is necessary to fully control the heating process of the Zhonggongguan 100. In order to properly control these heating processes, the heating process must be selected as much as possible, and γ & In the 雒Β 测 知 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空 中空How to read the sneak peek of the hollow squad 100 rotation, heating, etc. and know the condition of the hollow tube 1 皿 is one of the first problems to be overcome in the manufacture of alloy tubes. s Since no reference to Figure 2, the current method for measuring the temperature of the hollow tube 100 in the heating process at a temperature of 1308182 degrees is to use a thin sensing head 2 (the crucible is fixed to the hollow tube) The outer peripheral surface 1G7' of 1〇0 measures the temperature of the outer surface iG7 of the middle cymbal (10), and then estimates the outer peripheral surface ι〇6 of the hollow #(10) by the heat conduction theory, and the heat conduction is not equal. The temperature of the hollow outer peripheral surface 1G7 obtained by the measurement is affected by the surrounding environment, and the method of obtaining the temperature of the inner peripheral surface 1〇6 of the hollow f 100 inevitably causes a great error, which makes the manufacturer unable to trust. Within the obtained ^^ι〇〇

The circumferential surface 107 @temperature·'further' is also because the hollow tube 100 is continuously rotated in the same direction around a self-axis 1〇1 in the process of the alloy tube. Therefore, such a temperature measuring line 200 is disposed. In this way, the temperature measuring line _ is caused by the rotation of the hollow tube (10) depending on the hollow f(10), resulting in loss of equipment. Referring to FIG. 3', another method for measuring the temperature of the hollow tube i (8) during heating is to pierce the temperature measuring line 2 from the outer peripheral surface of the hollow tube 1 沿 in the radial direction. In the hollow tube i (8), and the sensing head 2 〇 1 of the temperature measuring line is fixed; the tube body (8) of the hollow tube (10) is wiped, and the connector 202 of the temperature measuring line is fixed to one The recorder 203 measures the temperature adjacent to the inner circumferential surface 106 of the hollow tube WO. In this way, although the temperature of the inner circumferential surface 106 adjacent to the hollow tube 1 可以 can be reliably measured, however, since the hollow tube 1 绕 is around the own axis 101 in the process of the alloy tube Rotating to the ground, therefore, the manner in which the cloth does not have the temperature measuring line 200 still causes the temperature measuring line 2 to wrap around the hollow tube 1 as the hollow tube 100 rotates. Causes the loss of equipment. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a temperature measuring line embedding method that accurately measures the temperature distribution change of a closed tube during heating. Another object of the present invention is to provide a temperature measuring line embedding method which does not occur in the process of manufacturing the rotation of the alloy tube, and does not occur in the process, and is suitable for the method of embedding the temperature measuring line of the present invention.

The eighth line 'the third inner measuring eight groove bottom is fixed to the third inner point to be measured, and the third inner temperature measuring line is along the eighth groove to the seventh slot and passes through the sixth, fourth, 3. The slot is opposite to the connector of the sensing head to expose the first surface, and the outer temperature measuring group further includes a third outer temperature measuring line stacked in the second outer temperature measuring line. The sensing head of the third outer temperature measuring line is fixed to the third outer measuring point, and the connecting head opposite to the sensing head is exposed to the first through the seventh, sixth, fourth, second and one slots surface. 5. The method of embedding a temperature measuring line according to claim 1 or 4, further comprising stacking a protective wire between the outer temperature measuring wire group and the outer circumferential surface. 6. The method of embedding a temperature measuring line according to claim 1 or 4, wherein the inner and outer temperature measuring lines are thermocouple wires, respectively. twenty two
