Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Example one
For the convenience of understanding the present embodiment, an operating environment of the tapping apparatus for performing the tapping control method disclosed in the embodiments of the present application will be described first.
As shown in fig. 1, the tapping apparatus 100 in the present embodiment includes: a stepping device 110, a detector 120, a steel tapping furnace door (not shown), a steel tapping machine 130, and a steel tapping rollgang 140.
In this embodiment, the step device 110 may include: lifting hydraulic cylinders, lifting displacement sensors, translation hydraulic cylinders, translation displacement sensors, walking beams and the like (only walking beams are shown in the figure). Wherein the walking beam includes a movable beam 111 and a fixed beam 112. The lifting hydraulic cylinder drives the movable beam to ascend or descend, the translation hydraulic cylinder drives the movable beam to move forwards or backwards to realize the movement of the steel billet in the furnace, and the lifting displacement sensor and the translation displacement sensor detect the position of the movable beam so as to realize the detection of the position of the steel billet.
The detector 120 described above may be a laser detector. The laser detector is used for detecting whether the steel billet reaches the steel tapping position or not and detecting the number of the steel billets entering the steel tapping position.
For example, the automatic lifting of the tapping furnace door can be realized through hydraulic drive and limit detection of a cam switch.
In this embodiment, the steel tapping machine may include a steel tapping motor 131, an encoder 132, a gear box 133, a steel tapping arm 134, a steel tapping arm lifting hydraulic cylinder (not shown), a lifting limit detection switch (not shown), and the like. Illustratively, the motor drives the steel-tapping arm to realize the forward movement, the backward movement and the like of the steel-tapping arm, and the steel-tapping arm is hydraulically driven by a steel-tapping arm lifting hydraulic cylinder to realize the ascending and descending functions of the steel-tapping arm. The encoder is used for controlling the movement amount of the outer steel arm. The steel tapping conveying roller way conveys the steel billet from the heating area to the steel rolling area through the driving of a motor.
In the example shown in fig. 1, a plurality of billets were placed on the walking beam, wherein two billets were located in a steel tapping position L3, wherein the overflowing amount of the first billet was L2, and the overflowing amount of the second billet was L1.
The tapping apparatus 100 in the present embodiment can be used for performing the steps in the methods provided in the embodiments of the present application.
The current tapping process is generally based on the fact that all billet steps in the heating furnace are not changed. In some examples, the billet fed into the furnace may have various cross-sections of 210 × 210mm, 280 × 280mm, 320 × 320mm, 320 × 425mm, etc. The step pitch of the walking beam of the heating furnace can be 500mm or 400mm, and 65 steel billets can be loaded in the heating furnace when the step pitch of 500mm is selected; when the step pitch of 400mm is selected, 82 steel billets can be loaded into the heating furnace, and if all the steel billets in the heating furnace are heated and transferred according to the step pitch of 400mm or the step pitch of 500mm, the current tapping flow of the heating furnace can meet the production requirements.
However, in order to improve the heating efficiency, different pitches may be selected according to different billets entering the cross section of the furnace in actual production, and when the pitch is changed from 400mm to 500mm, two billets may be present at the steel tapping position, and thus the heating furnace may be abnormal during semi-automatic steel tapping.
For example, after the steel tapping machine finishes taking a first steel billet, a laser detector in the heating furnace still detects a steel signal at a steel tapping position, the walking beam cannot move and stops at an original position of the walking beam, when the steel tapping position has steel, no steel billet exists in a steel tapping conveying roller way, the steel tapping machine is at the original position, when a steel signal is needed in a steel rolling area, a steel tapping period needs to be manually started, a steel tapping arm still determines a steel tapping stroke according to the position of the first steel billet, a second steel billet is moved forwards to take the second steel billet, and the second steel billet at the steel tapping position cannot be taken when the steel tapping arm ascends due to insufficient steel tapping stroke, so that production is interrupted; each piece of steel needs a heating furnace operator to manually start a tapping period, and the production efficiency is influenced. Based on this, in order to solve the problem that two or more steel billets may exist at a steel tapping position when the different step distances are switched, and abnormality occurs when the heating furnace taps in a semi-automatic control mode, a steel tapping control method is provided. The tapping control method according to the embodiment of the present application is described below.
Example two
Please refer to fig. 2, which is a flowchart of a tapping control method according to an embodiment of the present application. The specific process shown in fig. 2 will be described in detail below.
And 301, driving the movable beam to move according to a set track so as to drive the steel billet on the fixed beam to move towards the steel tapping position.
Illustratively, the walking beam comprises a movable beam and a fixed beam, and the movable beam can drive a steel billet to move from one end of the fixed beam to the other end of the fixed beam.
Illustratively, step 301 may include the following steps.
And 3011, when the steel tapping clearance timer reaches a set time, controlling the walking beam to move along a first direction so that the walking beam reaches a specified height.
Alternatively, the movable beam may be driven to ascend by a lifting hydraulic cylinder. For example, the lifting displacement sensor can detect the lifting position of the movable beam in real time during the lifting process of the movable beam. And controlling the movable beam to stop rising when the movable beam rises to a specified height based on the detection value of the lifting displacement sensor.
Alternatively, the specified height may be a preset value. Illustratively, the specified altitude may also be different for different use environments.
Illustratively, the first direction may be a direction perpendicular to a placement plane of the walking beam.
And 3012, controlling the movable beam to rotate along a second direction, so that the steel billet placed on the fixed beam moves from one end of the fixed beam to the other end, and the other end is the end where the steel tapping position is located.
Illustratively, the second direction may be the d2 direction shown in fig. 1.
In this embodiment, the first direction and the second direction may be perpendicular to each other.
The second direction may be a direction along the formation of the first end to the second end of the walking beam. The first end of the walking beam is the initial position of the steel billet placed on the walking beam, and the second end of the walking beam is the final position of the steel billet on the walking beam. The second end can be connected with the tapping position.
Alternatively, the movable beam can be driven to move forward according to the set step distance by the action of the translation hydraulic cylinder, so that the steel billet can move from the first end of the fixed beam to the second end of the fixed beam. For example, the set pitch may be 400mm or 500 mm.
For example, after the walking beam moves to the second direction according to the set step pitch, the lifting hydraulic cylinder can drive the movable beam to move to the opposite direction of the first direction until the movable beam moves to the set low position; then, the translation hydraulic cylinder can drive the movable beam of the walking beam to move towards the direction opposite to the second direction until the translation displacement sensor detects that the movable beam reaches the original position, and the movable beam stops retreating. The home position may refer to the position of the movable beam before step 301 is performed. The original position can also be the position of the movable beam when the movable beam is used for feeding the steel billet.
Optionally, the calculation of the steel tapping clearance time timer may be started before entering the stepping period, so that the stepping period is started after the set time. The stepping period may include a moving period of the movable beam.
Optionally, a laser detector can be further installed in the heating furnace, and the laser detector is used for detecting the number of the steel billets entering the steel tapping position.
For example, when the signal of the laser detector changes, it indicates that the first billet is detected to enter the steel tapping position, and the value of the first status register is updated to 1; when the signal of the laser detector changes again, it indicates that the second billet is detected to enter the steel tapping position, the value of the second status register is updated to 1, and so on, the values of the status registers in the same number as the number of the billets existing in the steel tapping position are updated to 1. Illustratively, when the value in the status register is 1, it indicates that a steel billet exists in the corresponding position in the steel tapping bit.
For another example, the number of the steel billets entering the steel tapping position is determined according to the signal change condition of the detector; and giving effective signal values to the state registers with the same number as the steel billets, wherein the effective signal values are used for representing that the steel tapping positions have the steel billets.
In this embodiment, when the movable beam moves forward in the second direction at the designated height, if two steel billets appear at the steel tapping position, the signal detected by the laser detector changes, where the change process of the signal of the laser detector is as follows: from no signal to signal, from signal to no signal, from no signal to signal. Alternatively, a counter may count the rising edges of the signal detected by the laser detector in the furnace, the count value is 1, which indicates that there is one passing billet in the steel tapping position, and the count value is 2, which indicates that there are two billets in the steel tapping position. When the count values are different values, the state registers are set, respectively, so that the signals stored in the state registers are 1. For example, when the count value is 1, the first status register is set; when the count value is 2, setting the first status register and the second status register respectively; when the count value is 3, the first status register, the second status register and the third register are set respectively.
In this embodiment, the moving process of the movable beam realized in step 301 may be regarded as a step period.
And 302, detecting the steel billets in the steel tapping position to determine the overflow amount of all the steel billets in the steel tapping position.
In one embodiment, step 302 may comprise: and determining the overflow amount of all steel billets in the steel tapping position according to the displacement of the movable beam detected by the displacement sensor.
Illustratively, the overflow amount of all steel billets in the tapping position can be determined according to the displacement of the movable beam detected by the translational displacement sensor.
Illustratively, the translational displacement sensor is coupled to the translational hydraulic cylinder for detecting movement data of the translational hydraulic cylinder. In this embodiment, the overflow amount of all steel billets in the steel tapping position can be determined according to the moving distance of the movable beam in the second direction.
In another embodiment, the start position of the tapping position is provided with a detector, and step 302 may include the following steps.
And step 3021, determining a start position of each steel billet entering the steel tapping position according to the change of the signal of the detector.
For example, when the value of the first status register is updated to 1, the current detection value of the translational displacement sensor may be recorded as the start bit of the first billet overflow amount.
For example, when the value of the second status register is updated to 1, the current detection value of the translational displacement sensor may be recorded as the start bit of the second billet overflow amount.
In this embodiment, as shown in fig. 1, the start position of the steel billet overflowing amount in the steel tapping position may be a mounting position of the detector.
And step 3022, when the movable beam stops, determining the end position of each steel billet at the steel tapping position according to the displacement of the walking beam detected by the displacement sensor.
Alternatively, when the movable beam moves in the direction opposite to the first direction and the current value of the first status register is 1, the current detection value of the translational displacement sensor may be recorded as the end bit of each billet overflow amount.
And step 3023, calculating the overflow amount of the target steel billet according to the start bit of the target steel billet and the end bit of the target steel billet for each target steel billet in the steel tapping position.
For example, the position difference between the start bit and the end bit of any one billet can be used as the overflow amount of the billet.
And 303, sequentially determining a steel taking stroke of the steel arm for taking each steel billet in the steel tapping position according to the overflow amount of each steel billet in the steel tapping position.
For example, the current position of the steel tapping arm can be used as the starting point of the steel tapping arm, and the position of the steel billet determined by the overflow amount of each steel billet can be used as the end point of the steel tapping arm, and the steel tapping stroke required for taking each steel billet can be determined according to the starting point and the end point of the steel tapping arm.
And 304, controlling the steel discharging arm to sequentially take out all steel billets in the steel discharging position according to the steel taking stroke of each steel billet.
Optionally, before performing step 304, it may be determined whether the walking beam returns to the original position, and if the walking beam returns to the original position, step 304 may be performed; if the movable beam does not return to the original position, the step 304 is executed after the movable beam returns to the original position.
Optionally, step 304 may include: before the steel billet in the steel tapping position is taken each time, acquiring a signal value of a current state register; and if the signal value indicates that the steel tapping position currently has steel billets, controlling the steel tapping arm to tap the steel billets arranged at the first position in the steel tapping position according to the steel tapping stroke corresponding to the current state register.
Optionally, step 304 may include: controlling the steel tapping arm to move to a first position according to the steel taking stroke; controlling the steel tapping furnace door to rise to a target position where the steel tapping position is located; controlling the steel tapping arm to move to the target position according to the steel taking stroke, and controlling the steel tapping furnace door to be opened; controlling the steel tapping arm to take the steel billet at the steel tapping position; and controlling the steel discharging arm to retreat to the specified position of the steel discharging conveying roller way.
Illustratively, the designated position of the steel delivery roller way can be the position of the central line of the steel delivery roller way.
In this embodiment, the time required to take one of the steel billets in step 304 may be used as a steel taking period.
In the embodiment of the application, in order to enable the heating time of each billet to meet the requirement, the time from the placing to the taking out of each billet needs to reach the set time length. For example, after one stepping cycle, when a plurality of steel billets reach the steel tapping position, steel taking can be delayed, so that the time required for taking out each steel billet is the same.
Illustratively, step 304 includes: when the first steel blank in the steel tapping position is taken, and when the positions of all components in the steel tapping equipment meet the conditions, the steel discharging arm can be started to take the first steel blank; when the Nth steel billet is taken, when the positions of all components in the steel tapping equipment meet the conditions and the current time and the time length when the previous steel taking is finished reach the time length of the stepping period, the steel taking arm can be started to take the Nth steel billet, wherein N is a positive integer greater than one.
Optionally, the tapping control method in this embodiment may further include: when the steel discharging arm starts to take the steel billet in the steel discharging position, the steel discharging clearance timer stops timing; and when the steel discharging arm finishes taking the steel billet in the steel discharging position at any time, the steel discharging clearance timer is cleared and times again.
Illustratively, the satisfying of the positions of the respective components in the tapping apparatus may include: the movable beam is arranged at the original position of the movable beam, no steel billet exists on the steel tapping conveying roller way, and the steel tapping machine is arranged at the original position of the steel tapping machine.
Optionally, whether the current time and the time length when the previous steel taking is finished reach the stepping period time length or not can be judged through the timing of the steel tapping clearance timer.
For example, if it is determined that the signal value of the first status register is 1, the movable beam is at the home position of the movable beam, no steel billet exists on the steel tapping roller conveyor, and the steel tapping arm is at the home position of the steel tapping arm, the first steel tapping in step 304 may be performed. The steel tapping furnace door begins to rise under the hydraulic drive; when the cam switch detects that the furnace door reaches a half-open position and stops rising, the steel-tapping motor drives the steel-tapping arm to move forwards according to the forward stroke of the steel-tapping arm determined by the overflow amount of the first steel billet at the steel-tapping position, the steel-tapping clearance timer resets, and the timing is stopped. When an encoder of the steel tapping motor detects that the steel tapping arm reaches a forward moving node in the first steel taking stroke, the steel tapping arm stops moving forward. The steel tapping furnace door is driven by hydraulic pressure to rise from a half-open position, the cam switch detects that the furnace door rises to a specified height, the steel tapping furnace door stops rising, and the steel tapping arm begins to rise under the drive of the lifting hydraulic cylinder; when the steel-tapping high-position approach switch detects that the steel-tapping arm rises to a specified height, the steel-tapping arm stops rising, and after the steel-tapping arm takes the first billet at the steel-tapping position, the steel-tapping arm starts to retreat. When an encoder of the steel tapping motor detects that the steel tapping arm retreats to the center line of the steel tapping conveying roller way, the first steel billet can be released, after the first steel billet is released by the steel tapping arm, the steel tapping arm starts to descend under the driving of the lifting hydraulic cylinder to return to the forward moving node of the steel tapping arm, in the process that the steel tapping arm returns to the forward moving node, the signal value of the first state register is updated to 0 from 1, the steel tapping clearance timer is set, and the timer is reset and starts to count again. The steel-tapping arm low-level approach switch detects that the steel-tapping arm descends to a forward moving node of the first steel-taking stroke, the steel-tapping arm stops descending, the steel-tapping arm starts to retreat under the drive of a motor, and the steel-tapping furnace door starts to descend under the drive of a lifting hydraulic cylinder; when an encoder of the steel tapping motor detects that the steel tapping arm retreats to the original position of the steel tapping arm, the steel tapping arm stops retreating, a cam switch detects that the furnace door descends to a low position, and the steel tapping furnace door stops descending; and (3) steel billets are arranged on the steel tapping conveying roller way, a steel rolling area has a steel requiring signal, and the steel tapping conveying roller way is started to convey the steel billets to the steel rolling area. As shown in fig. 1, the direction of the steel slab transferred by the steel delivery roller may be d1 direction shown in fig. 1. The centre line of the tapping rollgang may be m1 shown in fig. 1.
In this embodiment, before the steel discharging arm is started to take out the steel billet for the second time, the steel discharging arm may be started to take out the second steel billet after the time reaches the required time.
For example, after the first steel billet is taken, if the signal value of the second status register is 1, the steel tapping roller table has no steel billet, the steel tapping arm is at the original position of the steel tapping arm, and the timing of the steel tapping clearance time timer reaches the sum of the steel tapping timing time and the stepping period time, the second steel taking in step 304 can be executed, and the steel tapping furnace door starts to ascend under the hydraulic drive; when the cam switch detects that the furnace door reaches a half-open position and stops rising, the steel tapping motor drives the steel tapping arm to move forward, the steel tapping clearance timer resets, and the timing is stopped.

When the steel tapping motor encoder detects that the steel tapping arm retreats to the center line of the steel tapping conveying roller way, a second steel billet can be released, after the steel tapping arm releases the second steel billet, the steel tapping arm starts to descend under the driving of the lifting hydraulic cylinder so as to return to a forward moving node of the steel tapping arm, in the process that the steel tapping arm returns to the forward moving node of the second steel taking stroke, the signal value of the second state register is updated to 0 from 1, the steel tapping gap timer is set, and the timer is reset and starts to count again; when the steel tapping arm is detected to descend to the forward moving node of the second steel taking stroke by the steel tapping arm low-position proximity switch, the steel tapping arm stops descending, the steel tapping arm starts to retreat under the drive of a motor until the steel tapping arm moves to the original position of the steel tapping arm, and the steel tapping furnace door starts to descend under the drive of a lifting hydraulic cylinder; the steel tapping motor encoder detects that the steel tapping arm retreats to the original position of the steel tapping arm, the steel tapping arm stops retreating, the cam switch detects that the furnace door descends to the low position, and the steel tapping furnace door stops descending; steel billets are arranged on the steel tapping conveying roller way, steel-requiring signals are arranged in the steel rolling area, and the steel tapping conveying roller way is started to convey the steel billets to the steel rolling area; and finishing the automatic tapping process.
In this embodiment, if there are three or more steel billets in the steel tapping position, the second steel billet may be taken, so that the heating duration of each steel billet can be met while the steel is taken automatically.
In the embodiment, the steel tapping process of the heating furnace can be controlled by the signal in the state register to prepare steel; when the signal value of the second state register is 1, the overflow amount of the second billet can be calculated, the steel-tapping arm can calculate the stroke of the steel-tapping arm moving forwards to the second billet according to the overflow amount of the second billet, and the situation that the second billet cannot be taken when the steel-tapping arm rises is avoided. Furthermore, the signal value of the state register is 1, the steel tapping period is started for the second time, and in order to ensure the heating time of each steel billet, the timing control mode is effective, when the second steel tapping period is started, the condition that the timing time of the steel tapping clearance timer needs to reach the sum of the steel tapping timing time and the stepping beam stepping period time is increased, so that the heating time of the steel billets cannot be influenced even if two or more steel billets need to be taken out in one stepping period, the continuity of automatic steel tapping under abnormal conditions is ensured, and the production efficiency is improved.
