The present invention relates to a temperature measuring device for a moving slab in a continuous casting and rolling process, etc., and more specifically, to a temperature measuring device that is optimal for being embedded in a slab by utilizing the rotational pressing force of a roll that contacts the surface of the slab. . Conventionally, as a method for continuously measuring the temperature of a moving slab, the method described in Japanese Patent Publication No. 54-41434, for example, is known. The temperature measuring device disclosed in this invention has a minute metal piece connected to the tip of a sheathed thermocouple, and the minute metal piece is welded to the surface of the slab before embedding it in the slab. Since this device welds the minute metal pieces to the slab in advance, there is no problem of the metal pieces coming off from the slab after burying, but there is a problem with this device that a welding process is required. This invention eliminates the need for extra effort by welding the metal piece located at the tip of the temperature measurement means to the slab in advance, and allows micrometallurgical measurements to be made by simply applying the rotational pressing force of the rolls that come into contact with the surface of the slab, as in the past. The present invention provides a temperature measuring device for moving slabs that enables stable and continuous temperature measurement by burying pieces of metal and reliably preventing them from coming off after burying. , a metal piece that is pressed and buried in the slab and has a recess formed on the side surface of the outer surface in the direction of pressing, which becomes a locking part for preventing removal after embedding, and a measuring device such as a sheathed thermocouple connected to the metal piece. The present invention relates to a temperature measuring device for a moving slab, which comprises a warming means. Hereinafter, the details of the present invention will be explained based on the illustrated embodiment. FIG. 1 shows an embodiment of the present invention, in which a groove 2 is bored in the outer peripheral surface of a wedge-shaped metal piece 1, and the metal The tip of a measuring means 3 such as a sheathed thermocouple is connected to the piece 1. As shown in the figure, since the metal piece has a wedge shape, it is easily bitten by the rolls that come into contact with the surface of the slab 4, and is easily embedded within the slab by the pressing action of the rolls. As shown in FIG. 2, the metal piece 1 after embedding does not come out of the cast piece due to the retaining action of the groove 2 cut in the outer circumferential surface of the metal piece. Fig. 3 shows another embodiment of the present invention, in which Fig. 3 shows a cylindrical metal piece 1 with a groove 2 formed on its side surface, and has a certain limited direction to be bitten by a roll. Moreover, it is easy to manufacture and inexpensive. B is one in which one or more grooves 2 are provided on the side surface of a prismatic metal piece 1, and each metal piece has a temperature measuring means 3 such as a sheath type thermocouple.
is provided. As shown in FIG. 4, the moving slab temperature measuring device according to the present invention is configured to guide the metal piece 1 located at the tip of the device onto the surface of the moving slab 4 near the roll entrance 7 of the roll 6. By feeding it, it is pressed and buried in the slab 4, as shown by the imaginary line in the figure.
This device enables continuous measurement of temperature changes as the slab moves, and the device of the present invention, especially those shown in Figs.
The table shows the test results obtained in actual operation using the equipment shown in Figure A. Also, as a comparative example, the results obtained by the conventional method described above are also shown. In the experiment, after embedding a metal piece in a slab, continuous temperature measurements were conducted to determine whether the readings of the meter were stable within a certain range. In other words, if the metal piece is securely fixed in the slab, the indicated value will indicate the change in slab temperature within a certain temperature range, but if the metal piece is detached from the slab, the indicated value will change. The temperature drops rapidly and exceeds a certain temperature range. Then, when the indicated value was stable, it was considered a success, and when the indicated value suddenly dropped, it was judged as a failure, and the success rate was calculated.

It can be said that the metal piece after embedding the cast slab shows that the embedding work was carried out, and that the removal prevention effect of the groove provided in the metal piece functioned effectively. In the conventional method, since no recesses are provided to prevent the metal from slipping out, the surface of the cast piece of minute metal pieces may be damaged under adverse conditions such as high temperature and surfaces covered with oxide films. This is thought to be due to the difficulty of welding to the slab, which caused minute metal pieces to separate from the slab during temperature measurement. Although it is optional to use an appropriate method for press-embedding and feeding the temperature measuring device into the moving slab, in the present invention, as shown in FIGS. 5 and 6, A roll 10 that contacts the surface of the slab is pivoted to the end of a main body piece 9 connected to a guide 8 that comes into contact with the edge of the movable slab 4 to prepare for positioning.
A guide tube 11 that bends toward the roll inlet 7 is provided upright on the main body piece 9, and a temperature measuring means 3 is attached to this guide tube 11.
This can be done easily and reliably by using the guide device 12 that inserts the metal piece 1 through the guide tube 11 to place the metal piece 1 below the guide tube 11. In the above-mentioned guide device, it goes without saying that the roll is pivotally attached to the guide 8, and that the guide tube 11 is not limited to the one shown in the figure, but may be of a plate shape, for example. As described above, the moving slab temperature measuring device according to the present invention is press-embedded within the slab, and a recessed part that becomes a locking part to prevent slipping out after being buried is formed on the side surface of the outside surface facing the pressing direction. metal piece and
Since it consists of a temperature measuring means such as a sheathed thermocouple connected to the metal piece, it will not come off even if the temperature measuring device is subjected to an external action such as tension or vibration, and will always be in a stable state. It can measure temperature continuously.
