[0038] Other advantages and embodiments of the application will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that any such
[0039] It is also to be understood that the following description is only illustrative of the present application and is not intended to limit the present application thereto.
[0040] In the following description, numerous specific details are discussed in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to one of ordinary skill in the art that the embodiments of the present application can be practiced without these specific details. In other instances, well-known structures and devices are not described in detail in order to avoid obscuring the embodiments of the present application.
[0041] Reference will now be made to the drawings, in which Figure 1 Figure 1 is a flowchart of a bar rolling temperature determination method according to an exemplary embodiment of the present application. Referring to Figure 1 It can be seen that the bar rolling temperature determination method can include:
[0042] In step S110, rolling information in a bar rolling process is acquired.
[0043] The rolling information includes a plurality of rolling temperatures, and a temperature acquisition time corresponding to each rolling temperature.
[0044] In an embodiment of the present application, the rolling information in the bar rolling process can be acquired first. In actual application, a temperature detection device can be set at a detection position, and the temperature detection device can continuously collect the temperature of the bar at a preset interval.
[0045] Exemplarily, the detection position can include a rough rolling inlet, a rough rolling outlet, a pre-precision rolling inlet, a pre-precision rolling outlet, a precision rolling inlet, and a precision rolling outlet.
[0046] In step S120, a temperature control time is determined according to the position of the bar.
[0047] In an embodiment of the present application, the temperature control time can be any one of a rough rolling start time, a rough rolling end time, a pre-precision rolling start time, a pre-precision rolling end time, a precision rolling start time, and a precision rolling end time according to the position of the bar. The temperature control time can also be other time related to temperature control. That is, in actual use, the temperature control time can be determined according to the actual temperature control related control requirements.
[0048] It should be noted that the temperature control time can be determined according to the position of the bar. That is, when the bar is located at the rough rolling inlet position, the temperature control time can be determined as the rough rolling start time. When the bar is located at the rough rolling outlet position, the temperature control time can be determined as the rough rolling end time.
[0049] Step S130, determining a target time range corresponding to the temperature control time in a plurality of preset time ranges.
[0050] In an embodiment of the present application, the target time range corresponding to the temperature control time can be determined in a plurality of preset time ranges.
[0051] It should be noted that the rough rolling start time, the rough rolling end time, the pre-precision rolling start time, the pre-precision rolling end time, the precision rolling start time, and the precision rolling end time can each correspond to a different preset time range. After the temperature control time is determined, the target time range can be determined in the preset time range.
[0052] For example, the preset time range corresponding to the rough rolling start time can be [rough rolling start time-5, rough rolling start time+30], and the time unit can be seconds. The preset time range corresponding to the pre-precision rolling end time can be [pre-precision rolling end time-30, pre-precision rolling end time+5]. The specific preset time range can be set by the operator according to the actual situation.
[0053] Step S140, determining the rolling temperature at the temperature acquisition time in the target time range as the target temperature.
[0054] In an embodiment of the present application, the rolling temperature at the temperature acquisition time in the target time range can be determined as the target temperature. Since each rolling temperature corresponds to a temperature acquisition time, the target temperature can be determined according to the temperature acquisition time and the target time range.
[0055] In an exemplary embodiment, step S140 of determining the rolling temperature at the temperature acquisition time in the target time range as the target temperature can include steps S141 to S143.
[0056] Step S141, determining the rolling temperature at the temperature acquisition time in the target time range as a to-be-processed temperature.
[0057] In one embodiment of the present application, the rolling temperature of the temperature acquisition time within the target time range can be determined as the to-be-processed temperature.
[0058] In step S142, the target temperature range corresponding to the temperature control time is determined from the plurality of preset temperature ranges.
[0059] In one embodiment of the present application, the target temperature range corresponding to the temperature control time can be determined from the plurality of preset temperature ranges.
[0060] It should be noted that the rough rolling start time, the rough rolling end time, the pre-precision rolling start time, the pre-precision rolling end time, the precision rolling start time and the precision rolling end time can correspond to different preset temperature ranges one by one, and after the temperature control time is determined, the target temperature range can be determined from the preset temperature range.
[0061] For example, the temperature range corresponding to the rough rolling start time can be a range greater than 700℃, and the temperature range corresponding to the pre-precision rolling start time can be a range greater than 600℃. The specific preset temperature range can be set by the operator according to the actual situation.
[0062] In step S143, if the to-be-processed temperature is within the target temperature range, the to-be-processed temperature is determined as the target temperature.
[0063] In one embodiment of the present application, if the to-be-processed temperature is within the target temperature range, the to-be-processed temperature can be determined as the target temperature. If the to-be-processed temperature is not within the target temperature range, the to-be-processed temperature can be determined as abnormal data, and after the abnormal data is removed, a plurality of target temperatures are determined to improve the accuracy of the temperature value determined in the subsequent step.
[0064] In step S150, the control temperature corresponding to the temperature control time is determined according to the plurality of target temperatures.
[0065] In one embodiment of the present application, the control temperature corresponding to the temperature control time can be determined according to the plurality of target temperatures.
[0066] It should be noted that the average of the plurality of target temperatures can be determined as the control temperature, and the median of the plurality of target temperatures can also be determined as the control temperature, which is not limited in the embodiments of the present application.
[0067] It should be noted that the control temperature can be acquired by the operation control system, which is convenient for the production process to analyze the control temperature for production temperature control optimization.
[0068] The rod rolling temperature determination method provided in the embodiment of the application solves the problem of inaccurate and unstable temperature in the temperature calculation process, and has better benefits for monitoring and controlling the production process of the production line. The method is also applicable to temperature calculation of similar other continuous rolling.
[0069] In summary, the scheme of the embodiment of the application determines the control temperature corresponding to the temperature control time by acquiring the rolling information in the rod rolling process, the rolling information including a plurality of rolling temperatures and a temperature acquisition time corresponding to each rolling temperature, determining the temperature control time according to the position of the rod, determining the target time range corresponding to the temperature control time in a plurality of preset time ranges, and determining the rolling temperature in the target time range as the target temperature, and finally determining the control temperature corresponding to the temperature control time according to a plurality of target temperatures. The control temperature corresponding to the temperature control time can be accurately determined when the rod is rolled, so as to improve the accuracy of temperature control when the rod is rolled.
