Description

Technical Field

[0001] The invention relates to the technical field of narrow strip steel production, and in particular to a device and method for detecting the temperature of a narrow strip steel intermediate billet. Background Art

[0002] In the production process of narrow strip steel, the reliability of intermediate billet temperature detection is very important. It is directly related to the accuracy of the pre-setting of the mill roll gap and is an important part of ensuring smooth production and stable quality. However, due to the large range of intermediate billet width variations, the guide groove must be designed to adapt to the maximum width of the billet to ensure the smooth passage of the billet, which puts higher requirements on the pyrometer measurement. The original pyrometer used for detection adopts a single-center design. When measuring narrow intermediate billets, the billet randomly slides sideways in the wide guide groove, resulting in inaccurate or unmeasured pyrometers, which affects smooth production and stable quality.

DETAILED DESCRIPTION

[0015] To make the content of the present invention easier to be clearly understood, the following further detailed description of the present invention will be made according to specific embodiments in combination with the accompanying drawings.

[0016] Figure 1 It is a schematic structural diagram of the narrow strip steel intermediate billet temperature detection device provided by the embodiment of the present application. The device includes an intermediate billet guide groove 100, a temperature detection device 102, and a control component 103. The temperature detection device 102 can detect the temperature of the intermediate billet 101 passing through the intermediate billet guide groove 100, and transmit the detected temperature signal to the control component 103, and the control component 103 identifies and stores the temperature data.

[0017] Specifically, the intermediate billet guide groove 100 includes a bottom plate and two side plates fixedly arranged on both sides of the bottom plate, that is, the cross-section of the intermediate billet guide groove 100 is in a "C" shape. Among them, the width of the intermediate billet guide groove 100, that is, the distance between the two side plates, is greater than the width of any specification of the intermediate billet 101. Setting the intermediate billet guide groove 100 wider facilitates the smooth passage of intermediate billets 101 of different sizes in the intermediate billet guide groove 100.

[0018] There are two sets of temperature detection devices 102, and each set of temperature detection devices 102 includes a temperature detector. Among them, the positions of the two temperature detectors need to meet the following conditions: the detection areas of the two temperature detectors completely cover the width direction of the intermediate billet guide groove 100, see Figure 1 . In this way, when the intermediate billet 101 passes through the intermediate billet guide groove 100, no matter which position the intermediate billet 101 slides to on both sides, the intermediate billet 101 is within the detection area of the temperature detector, so as to ensure the accuracy of temperature detection.

[0019] The control component 103 is used to receive the temperature signal detected by the temperature detection device 102, identify the temperature signal as temperature data and store it. At the same time, the control component 103 can also preset a temperature threshold range, and compare the received temperature data of the intermediate billet 101 with the preset temperature threshold range to judge whether it is within the preset temperature threshold range. According to the temperature of the intermediate billet 101 detected by the temperature detection device 102, the accuracy of the presetting of the rolling mill roll gap can be ensured.

[0020] In this embodiment, the control component 103 includes a PLC controller.

[0021] The embodiment of the present application also provides a method for detecting the temperature of a narrow strip steel intermediate billet. This detection method is based on the above-mentioned narrow strip steel intermediate billet temperature detection device. This detection method specifically includes the following steps: Step S101: Control the intermediate billet to pass through the intermediate billet guide groove.

[0022] Step S102: Detect the temperature of the intermediate billet by a temperature detection device, and transmit the detected temperature signal to the control component.

[0023] Step S103: The control component receives and identifies the temperature signal detected by the temperature detection device, obtains and stores the intermediate billet temperature data.

[0024] Step S104: Compare the received intermediate billet temperature data with a preset temperature threshold range to determine whether it is within the preset temperature threshold range.

[0025] Therefore, the technical solution of the present application completely covers the width direction area of ​​the intermediate billet guide groove through multiple temperature detectors, so that no matter which position the intermediate billet slides to on both sides, the intermediate billet is within the detection area of ​​the temperature detector, thereby ensuring the accuracy of temperature detection.

[0026] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
