具体实施方式detailed description

提供参照附图的以下描述以帮助对由权利要求及其等同物限定的本发明的实施例的全面理解。包括各种特定细节以帮助理解,但这些细节仅被视为是示例性的。因此,本领域的普通技术人员将认识到在不脱离本发明的范围和精神的情况下,可对描述于此的实施例进行各种改变和修改。此外,为了清楚和简洁,省略对公知的功能和结构的描述。The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of embodiments of the present invention as defined by the claims and their equivalents. Various specific details are included to aid in understanding but are to be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

本发明示例性实施例的计算热连轧生产过程的停机时间的方法的本质是选取热连轧生产过程中两个关键工序加热和卷取,通过跟踪加热和卷取的生产情况监控热连轧生产过程的实际生产时间和停机时间,更好地管控热连轧生产。具体说来,本发明示例性实施例的计算热连轧生产过程的停机时间的方法可首先将热连轧的生产过程划分为多个时间段。例如,热连轧的生产过程可为一天24小时,那么可根据实际生产的需要将24小时划分为3个时间段。这里,作为示例,划分出的3个时间段可分别为:00:00-08:00为夜班,08:00-16:00为白班,16:00-24:00为中班。然后本发明示例性实施例的计算热连轧生产过程的停机时间的方法分别计算每个时间段中的停机时间。这里,停机时间可包括实际停机时间和等效停机时间。The essence of the method for calculating the downtime of the hot continuous rolling production process in the exemplary embodiment of the present invention is to select two key processes in the hot continuous rolling production process, heating and coiling, and monitor the hot continuous rolling process by tracking the production conditions of heating and coiling. The actual production time and downtime of the production process can better control the hot rolling production. Specifically, the method for calculating the downtime of the hot continuous rolling production process according to the exemplary embodiment of the present invention may firstly divide the hot continuous rolling production process into multiple time periods. For example, the production process of hot continuous rolling can be 24 hours a day, so 24 hours can be divided into 3 time periods according to the needs of actual production. Here, as an example, the divided three time periods may be: 00:00-08:00 for night shift, 08:00-16:00 for day shift, and 16:00-24:00 for middle shift. Then the method for calculating the downtime of the hot continuous rolling production process according to the exemplary embodiment of the present invention calculates the downtime in each time period respectively. Here, downtime may include actual downtime and equivalent downtime.

下面,将基于图1来描述计算任意时间段的实际停机时间和等效停机时间的方法。Hereinafter, a method of calculating actual downtime and equivalent downtime for an arbitrary period of time will be described based on FIG. 1 .

图1是示出根据本发明示例性实施例的计算热连轧生产过程的停机时间的方法的流程图。FIG. 1 is a flowchart illustrating a method of calculating downtime of a hot continuous rolling production process according to an exemplary embodiment of the present invention.

如图1所示,在步骤S10中,检测加热炉的出钢信号和卷取机的卷钢信号。As shown in FIG. 1 , in step S10 , the tapping signal of the heating furnace and the coiling signal of the coiler are detected.

在步骤S20中,计算当前检测到出钢信号或卷钢信号的时间点与上一次检测到出钢信号或卷钢信号的时间点的差值。这里,可计算当前检测到出钢信号的时间点与上一次检测到出钢信号的时间点的差值,或者计算当前检测到卷钢信号的时间点与上一次检测到卷钢信号的时间点的差值。In step S20, the difference between the time point when the steel tapping signal or the steel coil signal is detected and the time point when the steel tapping signal or the steel coil signal was detected last time is calculated. Here, the difference between the time point when the steel tapping signal is detected and the time point when the steel tapping signal was detected last time can be calculated, or the time point when the steel coil signal is currently detected and the time point when the steel coil signal was detected last time can be calculated difference.

在步骤S30中,当所述差值大于等于设定值时,将上一次检测到出钢信号或卷钢信号的时间点作为所述实际停机时间的起始时间点,将当前检测到出钢信号或卷钢信号的时间点作为实际停机时间的结束时间点。这里,设定值可由用户进行设定。In step S30, when the difference is greater than or equal to the set value, the time point when the tapping signal or the coil signal was detected last time is taken as the starting time point of the actual downtime, and the currently detected tapping signal The time point of the signal or coil signal is used as the end time point of the actual downtime. Here, the set value can be set by the user.

具体说来,当当前检测到出钢信号或卷钢信号的时间点与上一次检测到出钢信号或卷钢信号的时间点的差值小于设定值时,表明此时加热炉、卷取机都正常工作;当当前检测到出钢信号或卷钢信号的时间点与上一次检测到出钢信号或卷钢信号的时间点的差值大于等于设定值时,一般认为在生产过程中出现了问题。因此,这里可在所述差值大于等于设定值时将相应地上一次检测到出钢信号或卷钢信号的时间点作为所述实际停机时间的起始时间点,将当前检测到出钢信号或卷钢信号的时间点作为实际停机时间的结束时间点。Specifically, when the difference between the time point when the tapping signal or coiling signal is detected at present and the time point when the tapping signal or coiling signal was detected last time is less than the set value, it indicates that the heating furnace, coiling The machine is working normally; when the difference between the time point of the current detection of the steel tapping signal or the coil steel signal and the time point of the last detection of the steel tapping signal or the coil steel signal is greater than or equal to the set value, it is generally considered that in the production process something is wrong. Therefore, here, when the difference is greater than or equal to the set value, the time point when the tapping signal or the coil signal was detected last time can be used as the starting time point of the actual downtime, and the currently detected tapping signal Or the time point of the coil steel signal as the end time point of the actual downtime.

在步骤S40中,由所述时间段内包括的时间减去所述实际停机时间得到实际生产时间。例如,如果所述时间段为00:00-08:00的夜班,那么该时间段内包括的时间就为8小时,假设实际停机时间为2小时的话,那么实际生产时间就为8-2=6小时。In step S40, the actual production time is obtained by subtracting the actual downtime from the time included in the time period. For example, if the time period is the night shift from 00:00-08:00, then the time included in the time period is 8 hours, assuming that the actual downtime is 2 hours, then the actual production time is 8-2= 6 hours.

在步骤S50中,判断实际生产时间是否大于设定连续生产时间。这里,设定连续生产时间的值可由用户进行设定。In step S50, it is judged whether the actual production time is greater than the set continuous production time. Here, the value of the set continuous production time can be set by the user.

在步骤S60中,当实际生产时间大于等于设定连续生产时间时,根据轧件的轧制数据确定在实际生产时间内所述轧件的额定轧制块数。In step S60, when the actual production time is greater than or equal to the set continuous production time, the rated number of rolled blocks of the rolled piece within the actual production time is determined according to the rolling data of the rolled piece.

具体说来,当实际生产时间大于设定连续生产时间时,才需计算在实际生产时间内的等效停机时间,进而得知在实际生产时间内的轧钢生产节奏的快慢。Specifically, when the actual production time is greater than the set continuous production time, it is necessary to calculate the equivalent downtime within the actual production time, and then know the speed of the rolling production rhythm within the actual production time.

可选地,根据轧件的轧制数据确定在实际生产时间内所述轧件的额定轧制块数的步骤可包括:从生产控制级获取轧件的轧制数据;读取用户预定义的在实际生产时间内根据轧件的钢种和轧件轧制的目标厚度确定的所述轧件的额定轧制块数。这里,轧件的轧制数据可包括轧件的材料号(例如,钢卷号、板坯号)、轧件的钢种、轧件轧制的目标厚度。Optionally, the step of determining the number of rated rolling blocks of the rolled piece within the actual production time according to the rolling data of the rolled piece may include: obtaining the rolling data of the rolled piece from the production control level; reading the user-defined The number of rated rolled blocks of the rolled piece determined according to the steel type of the rolled piece and the target thickness of the rolled piece within the actual production time. Here, the rolling data of the rolled piece may include the material number of the rolled piece (eg, steel coil number, slab number), the steel type of the rolled piece, and the rolling target thickness of the rolled piece.

具体说来,从生产控制级获取轧件的轧制数据后,可读取用户预定义的在实际生产时间内将所述钢种的轧件轧制到所述目标厚度的块数,将用户预定义的块数作为在实际生产时间内轧件的额定轧制块数。这里,应该理解,由于钢种的不同以及轧制的目标厚度的不同,在实际生产时间内轧制出的块数也必然不同。Specifically, after obtaining the rolling data of the rolled piece from the production control level, the user can read the number of pieces that the rolled piece of the steel type is rolled to the target thickness predefined by the user within the actual production time, and the user The predefined block number is used as the rated rolling block number of the rolled piece in the actual production time. Here, it should be understood that due to differences in steel types and rolling target thicknesses, the number of blocks rolled within the actual production time must also be different.

在步骤S70中,记录在热连轧生产过程中从过程控制级接收到的所述轧件的跟踪数据,并根据所述跟踪数据计算在实际生产时间内出卷取机的所述轧件的块数,作为所述轧件在实际生产时间内的实际轧制块数。In step S70, record the tracking data of the rolling piece received from the process control level in the hot continuous rolling production process, and calculate the number of rolling pieces that exit the coiler within the actual production time according to the tracking data. The number of blocks is used as the actual number of rolled blocks of the rolled piece in the actual production time.

可选地,可从过程控制级接收轧件的跟踪数据。这里,轧件的跟踪数据可包括:轧件的材料号,例如,板坯号、钢卷号;轧件的跟踪信息,例如,轧件从加热炉出炉的出炉时刻、轧件进入卷取机的卷钢时刻,这里,所述出炉时刻和所述卷钢时刻成对出现。具体说来,在轧件经过加热炉加热出炉后,会生成出炉数据,出炉数据可包括轧件的钢卷号、轧件从加热炉出炉的出炉时刻,然后该钢卷号的轧件再经过卷取机进行卷钢,待卷取机完成卷钢操作后,会生成轧钢数据,轧钢数据可包括轧件的钢卷号、轧件进入卷取机的卷钢时刻。在步骤S70中记录的是在实际生产时间内在出炉数据和轧钢数据中都检测到对应钢卷号的轧件的块数。Optionally, stock tracking data may be received from a process control level. Here, the tracking data of the rolled piece may include: the material number of the rolled piece, for example, the slab number, the steel coil number; The time of steel coiling, here, the time of release from the furnace and the time of coil steel appear in pairs. Specifically, after the rolled piece is heated and released by the heating furnace, the furnace release data will be generated. The furnace release data can include the steel coil number of the rolled piece, the time when the rolled piece is released from the heating furnace, and then the rolled piece with the steel coil number is passed through The coiler performs coiling. After the coiler completes the coiling operation, the rolling data will be generated. The rolling data may include the coil number of the rolled piece and the coiling time when the rolled piece enters the coiler. What is recorded in step S70 is the number of rolled pieces corresponding to the steel coil number detected in both the furnace data and the steel rolling data within the actual production time.

在步骤S80中,根据在所述实际生产时间内所述轧件的实际轧制块数和额定轧制块数,计算等效停机时间。In step S80, the equivalent downtime is calculated according to the actual number of rolling blocks and the rated number of rolling blocks of the rolling piece within the actual production time.

可选地,根据在所述实际生产时间内所述轧件的实际轧制块数和额定轧制块数计算等效停机时间的步骤可包括:对实际生产时间内的轧件的实际轧制块数和额定轧制块数进行比较;当实际轧制块数小于额定轧制块数时,根据在实际生产时间内轧件的实际轧制块数和额定轧制块数,计算等效停机时间;当实际轧制块数大于等于额定轧制块数时,不计算等效停机时间。Optionally, the step of calculating the equivalent downtime according to the actual number of rolled blocks and the rated number of rolled blocks of the rolled piece within the actual production time may include: the actual rolling of the rolled piece within the actual production time Compare the number of rolling blocks with the rated number of rolling blocks; when the actual number of rolling blocks is less than the rated number of rolling blocks, calculate the equivalent shutdown according to the actual number of rolling blocks and the rated number of rolling blocks in the actual production time Time; when the actual number of rolled blocks is greater than or equal to the rated number of rolled blocks, the equivalent downtime is not calculated.

可选地,计算等效停机时间的公式如下:Optionally, the formula for calculating the equivalent downtime is as follows:

T1=(M2-M1)×t (1)T 1 =(M 2 −M 1 )×t (1)

公式(1)中,T1为等效停机时间,M2为实际生产时间内的额定轧制块数,M1为实际生产时间内的实际轧制块数,t为轧制一个轧件的标准轧制时间,其中,t0为实际生产时间。In the formula (1), T 1 is the equivalent downtime, M 2 is the rated number of rolling blocks in the actual production time, M 1 is the actual number of rolling blocks in the actual production time, t is the time to roll a rolling piece Standard rolling time, where, t 0 is the actual production time.

在步骤S90中,显示所述实际停机时间的起始时间点、所述实际停机时间的结束时间点、所述等效停机时间。In step S90, the start time point of the actual downtime, the end time point of the actual downtime, and the equivalent downtime are displayed.

当实际生产时间小于设定连续生产时间时,执行步骤S100:不计算等效停机时间。在此情况下,在步骤S90中仅显示所述实际停机时间的起始时间点、所述实际停机时间的结束时间点。When the actual production time is less than the set continuous production time, perform step S100: not calculate the equivalent downtime. In this case, only the start time point of the actual downtime and the end time point of the actual downtime are displayed in step S90.

可选地,在步骤S90中还可显示多个预定停机类型。在此情况下,根据本发明示例性实施例的计算热连轧生产过程的停机时间的方法可还包括:接收用户输入的用于从多个预定停机类型中选择一个预定停机类型的选择操作;响应于所述选择操作从显示的多个预定停机类型中选择一个预定停机类型。Optionally, in step S90, a plurality of scheduled shutdown types may also be displayed.

The operator on duty can only grant the permission to enter, modify and delete the shutdown information on duty.

可选地,根据本发明示例性实施例的计算热连轧生产过程的停机时间的方法可还包括:根据所述实际停机时间和所述等效停机时间,计算所述时间段的生产效率。Optionally, the method for calculating downtime of a hot continuous rolling production process according to an exemplary embodiment of the present invention may further include: calculating the production efficiency in the time period according to the actual downtime and the equivalent downtime.

可选地,计算所述时间段的生产效率的公式如下:Optionally, the formula for calculating the production efficiency in the time period is as follows:

公式(2)中,η为所述时间段的生产效率,t2为所述时间段内的有效作业时间,t2=T-t3,T为所述时间段内包括的时间,t3为实际停机时间,t1为所述时间段内的规定的生产作业时间。这里,规定的生产作业时间可以是在所述时间段内除了年修、检修、待料、待电、待气、待热、检查等时间之外的时间。In the formula (2), n is the production efficiency of the time period, t2 is the effective working time in the time period, t2 = Tt3 , T is the time included in the time period, and t3 is the actual time. Downtime, t 1 is the specified production operation time in the time period. Here, the specified production operation time may be time other than annual maintenance, overhaul, waiting for material, waiting for electricity, waiting for gas, waiting for heating, inspection, etc. within the time period.

可选地,根据本发明示例性实施例的计算热连轧生产过程的停机时间的方法可还包括:对从过程控制级接收到的轧件的跟踪数据进行标注。Optionally, the method for calculating downtime of a hot continuous rolling production process according to an exemplary embodiment of the present invention may further include: marking the rolling piece tracking data received from the process control level.

具体说来,从过程控制级接收到的轧件的跟踪数据中同一钢卷号的轧件的从加热炉出炉的出炉时刻(ta)和进入卷取机的卷钢时刻(tb)之差必需大于最小轧制时间(tmin),也就是说tb-ta>tmin,同时出炉时刻ta和卷钢时刻tb必需成对出现。如果在当前时间段的轧钢生产过程中只检测到出炉时刻ta,没有检测到卷钢时刻tb,则该段时间轧线必然出现了生产异常(例如,轧废、卡钢、回炉等);如果当前时间段的轧钢生产过程中只检测到卷钢时刻tb,没有检测到出炉时刻ta,则轧件的跟踪信号必然出错。在此情况下,可将仅检测到的出炉时刻ta或卷钢时刻tb标注为“疑问”。但是,对于在当前时间段的轧钢起始阶段出现的只检测到卷钢时刻tb,没有检测到出炉时刻ta则是正常的(出炉时刻ta在上一时间段),本发明示例性实施例的计算热连轧生产过程的停机时间的方法可自动修正添加一个最小轧制时间tmin的出炉时刻ta,在此情况下,ta=tb-tmin;对于在当前时间段的轧钢结束阶段出现的只检测到出炉时刻ta,没有检测到卷钢时刻tb(卷钢时刻tb在下一时间段),本发明示例性实施例的计算热连轧生产过程的停机时间的方法可自动修正添加一个最小轧制时间tmin的卷钢时刻tb,在此情况下,tb=ta+tminSpecifically, in the tracking data of the rolled piece received from the process control level, the time between the time when the rolled piece of the same coil number is released from the heating furnace (t a ) and the time when the coil enters the coiler (t b ) The difference must be greater than the minimum rolling time (t min ), that is to say t b -t a > t min , and at the same time the time t a of tapping and the time t b of coiling steel must appear in pairs. If in the steel rolling production process of the current period, only the time t a of the furnace is detected, and the time t b of the steel coil is not detected, then there must be production abnormalities in the rolling line during this period (for example, scrap rolling, steel jamming, furnace return, etc.) ; If only the coiling time t b is detected in the steel rolling production process in the current time period, but the firing time t a is not detected, the tracking signal of the rolled piece must be wrong. In this case, only detected tapping time t a or coiling time t b can be marked as "questionable". However, it is normal for the steel coiling moment t b to be detected at the initial stage of steel rolling in the current time period, and the time t a to be released is not detected (the time t a to be released from the furnace is in the previous time period). The method for calculating the shutdown time of the hot continuous rolling production process in the embodiment can automatically correct and add a minimum rolling time t min to the release time t a , in this case, t a =t b -t min ; for the current time period In the end stage of steel rolling, only the time t a of the furnace is detected, and the time t b of the steel coil is not detected (the time t b of the steel coil is in the next time period), the calculation of the downtime of the hot continuous rolling production process in the exemplary embodiment of the present invention The method can automatically correct and add a coil steel time t b with a minimum rolling time t min , in this case, t b =t a +t min .

此外,对于正常的热连轧的轧钢生产过程,轧件的生产开始时间和生产结束时间是成对出现的,并且生产开始时间和生产结束时间不能超过最大限定时间,因此,当轧件的生产开始时间和生产结束时间的差大于最大限定时间时,本发明示例性实施例的计算热连轧生产过程的停机时间的方法可对轧件的生产开始时间和生产结束时间标注为“修正”。In addition, for the normal hot rolling steel rolling production process, the production start time and production end time of the rolled piece appear in pairs, and the production start time and production end time cannot exceed the maximum limit time. Therefore, when the production of the rolled piece When the difference between the start time and the production end time is greater than the maximum limit time, the method for calculating the downtime of the hot rolling production process according to the exemplary embodiment of the present invention can mark the production start time and the production end time of the rolled piece as "correction".

采用本发明示例性实施例的计算热连轧生产过程的停机时间的方法,根据来自生产控制级和过程控制级的数据自动计算出停机时间,使对停机时间的获取更准确,有效提高了生产效率,保证热连轧调度信息的真实性。Using the method for calculating the downtime of the hot rolling production process in the exemplary embodiment of the present invention, the downtime is automatically calculated according to the data from the production control level and the process control level, so that the acquisition of the downtime is more accurate, and the production efficiency is effectively improved. Efficiency, to ensure the authenticity of hot rolling scheduling information.

尽管已经参照其示例性实施例具体显示和描述了本发明,但是本领域的技术人员应该理解,在不脱离权利要求所限定的本发明的精神和范围的情况下,可以对其进行形式和细节上的各种改变。While the invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that changes may be made in form and detail without departing from the spirit and scope of the invention as defined by the claims. various changes.
