Description

MOVING TYPE APPARATUS FOR MEASURING TEMPERATURE AND MOVING TYPE APPARATUS FOR MEASURING TEMPERATURE FOR STRIP MILL}

The present invention relates to a temperature measuring device, and more particularly, to measure a temperature using a mobile temperature measuring device for measuring the temperature of a material rolled in a finishing rolling device, a mobile temperature measuring device for a finishing rolling device, and a mobile temperature measuring device. It is about how to.

In the hot-phase rolling process, a series of continuous rolling of a material having a temperature of about 1050 ° C. and a thickness of several tens of millimeters after rough rolling is performed, thereby achieving a target thickness of about 2 to 20 mm and a target finishing rolling temperature of about 900 ° C. It is an important control item.

In the hot rolling process, the operation is performed at a very high temperature. Thus, the temperature of the material is a factor that greatly influences the setting of the appropriate rolling load to match the product thickness in addition to the aspects of securing the material. Therefore, in order to improve the quality of hot rolled products, it is essential to prepare a method capable of measuring and controlling the temperature change during the rolling process very accurately.

In general, the finishing rolling apparatus of the hot-thin rolling process includes a transfer table for transferring a material during finishing rolling, and about 6 to 7 stands continuously disposed at intervals of about 5 m. Each stand is provided with a water cooling facility such as a rolling mill for rolling the raw material and a spray for controlling the temperature of the raw material.

In addition, a temperature measuring device is provided at the exit side of the final stand. The temperature measuring device measures the temperature of the material discharged to the exit side of the final stand after rolling is completed. In the hot rolling process, an optimum rolling condition is set by adjusting the amount of cooling water and the rolling load according to the temperature measured by the temperature measuring device.

As a temperature measuring device for measuring the temperature of the material in the hot rolling process, a pyrometer (Pyrometer) that is disposed away from the material to measure the radiant heat of the material is mainly used.

Will be adjusted.

However, in the hot sand rolling process, since the raw material is variously distributed in temperature distribution according to each point, the temperature of the material at a point other than the measured point is different from the measured point temperature. Therefore, there is a limit in setting the optimum rolling conditions for each stand only by the temperature information obtained by the temperature measurement at any one point.

In addition, the temperature measuring device as described above, when water is generated between the temperature measuring device and the thick plate due to the cooling water is injected into the thick plate of the high temperature state, or part of the sprayed coolant stays on the upper plate, that is, stays on the upper plate If there is a number, this causes an error that the temperature measurement is not made accurately.

Hereinafter, a method of measuring temperature using the mobile temperature measuring apparatus according to the present embodiment will be described with reference to FIGS. 2 and 6 to 8.

2, 6 and 8, in order to measure the temperature using the mobile temperature measuring device 100, first, the position of the material 1 to be transferred is sensed (S10). That is, the mobile temperature measuring device 200 provided between the stand 110 and the stand 110 of the finishing rolling device 100 is formed of a material 1 on the corresponding stand 110, that is, the stand 110 adjacent to the front. ), The sensor starts to measure the temperature.

In this embodiment, the entry of the workpiece 1 is illustrated as being sensed by the looper 130. The material 1 entered into the stand 110 and entered between the rolling rolls of the rolling mill 112 is in contact with the looper 130, and the entrance detection of the material 1 is in contact with the material 1 and the looper 130. It can be made by.

2, 7 and 8, when the detected material 1 enters the set position, the mobile temperature measuring device 200 located on the upper part of the material 1 may move the material 1 and the mobile temperature. The measuring device 200 is moved to the material 1 side to maintain the set interval (S20).

In this embodiment, the set position is exemplified as the position of the work piece 1 in which the mobile temperature measuring device 200 of the present embodiment can effectively measure the temperature of the work piece 1, and the set interval is the movable type of the present embodiment. The temperature measuring device 200 is illustrated as being a distance between the material 1 and the mobile temperature measuring device 200 capable of effectively measuring the temperature of the material 1.

Since the set position and the set interval may be appropriately adjusted in consideration of the feed speed of the raw material 1 and the like, the description of specific values for the set position and the set interval is omitted herein.

According to this embodiment, the movement of the movable temperature measuring device 200 is made by the operation of the driving member 212. That is, when the looper 130 detects the entry of the material 1 and transmits a signal to the driving controller 258, the driving controller 258 receiving the signal from the looper 130 stops the operation of the driving member 212. The main body 210 is controlled to move in the lower direction, which is the material 1 side, and the temperature measuring part 250 is moved to the material 1 by the main body 210 which is thus moved.

When the temperature measuring unit 250 is moved to the material 1 side as described above, the driving control unit 258 operates the temperature measuring unit 250. Accordingly, the pyrometer 252 starts to measure the temperature of the material 1, and together with the fluid spraying device 256 injects a high-pressure fluid to the surface of the material 1, the water on the surface of the material 1 Removes foreign matter and water vapor such as scale or the like between the material (1) and the temperature measuring unit (250).
