Description

  The present invention virtually simulates the phenomenon that occurs in the molten metal in the mold of the continuous casting machine of the steel industry and the equipment around the mold using a computer, and trains the skill of the operator who performs the manual operation of casting. The present invention relates to a casting work training simulator apparatus for continuous casting.

  Since continuous casting machines in the steel industry handle high-temperature molten steel, once abnormalities occur in the automatic control system, hot-water supply system, or solidified slab, high-temperature molten metal leaks, causing serious damage to machines and operators. May give. And in such a case, it respond | corresponds so that steady operation may be performed, suppressing such a malfunction by manual operation by an operator. The continuous casting equipment will be briefly described. FIG. 8 is a schematic view of the continuous casting mold 1 in operation as viewed from the upper opening. The molten steel surface 2 inside the mold 1 is called a molten metal surface. The hot water surface height is automatically controlled so that the height detected by the hot water surface level meter 3 usually installed above coincides with the target value. The flow rate of the molten steel injected into the mold 1 is adjusted by the opening degree of the nozzle device that can change the opening area installed in the joint portion 5 between the tundish 4 and the immersion nozzle.

Further details are as follows. A powder mold powder is placed on the molten steel surface 2 and melted by the heat of the molten steel. The molten mold powder wraps around between the solidified shell of steel and the mold 1 by the vertical movement (oscillation) of the mold, and promotes lubrication between the solidified shell and the mold 1.
Here, from the boundary between the unmelted or slag-shaped mold powder on the molten steel and the mold, the color of the molten steel, the emitted light, or the flame may be visible when the molten metal surface 2 descends. For example, when the molten metal level meter 3 breaks down, the operator of the continuous casting machine manually controls the nozzle opening. At this time, the hot water level is caused by such a light emission phenomenon that occurs between the mold 1 and the molten metal surface 2. Grasp the surface and adjust the nozzle opening.

  Also, at the start of casting, a device called a dummy bar is usually installed in the strand so as to close the bottom of the mold 1, and after the molten steel initially injected has solidified to a sufficient strength, the dummy bar is pulled out with a pinch roll. Start casting. The flow of molten steel coming out of the nozzle outlet is called the discharge flow. In addition to the case where the normal flow rate can be secured, the discharge flow rate is increased when the flow rate of the discharge flow with respect to the nozzle opening is reduced due to clogging in the nozzle, or due to melting damage deformation of the nozzle refractory There is a case.

  Since the discharge port can be observed directly at the start of casting, the operator can observe the momentum of the discharge flow or the diameter of the flow, the spark generated when the molten steel touches the air, and the splash momentum when the molten steel discharge flow collides with the upper surface of the dummy bar. By volume, the flow rate of the discharge flow can be grasped visually. However, when the operator determines that the flow rate of molten steel is extremely small compared to the indication value of the opening of the nozzle, which may hinder operation, the nozzle refractories and nozzles should be checked after grasping the nozzle clogging and melting damage. An operation of blowing and dissolving oxygen gas on the inclusions attached to the inner wall is performed.

  In recent years, various automated techniques have been developed, and techniques for predicting or detecting these abnormal states at an early stage have also been developed. However, such prediction and detection cannot completely eliminate the occurrence of an abnormality, and the influence at the time of malfunction is great. Therefore, monitoring by personnel is still necessary, and an operator waits around the mold and responds by manual operation when an abnormality occurs. For the above example, for example, the continuous casting machine is provided with a manual control device for instructing the nozzle opening with the opening direction or closing direction button, and the nozzle opening can be manually adjusted by operating this. It is also possible to set the slab drawing speed with a manual dial device or the like. In other words, these devices can be used when there is an abnormality in the molten steel supply, slab drawing, automatic control system, or in-mold slab, and the molten metal overflows from the mold or the molten steel surface remains exposed. The operator can manually control the amount of molten metal flowing into the mold and the drawing speed of the slab so that the slab is not completely pulled out from the mold.

  On the other hand, such skills and knowledge of operators can be acquired by experiencing many equipment failures and troubles in daily work, but recently, due to the reduction of equipment failures and the development of automation technology. The number of times that trouble can be experienced during actual operation is decreasing. In workplaces where the number of retired workers is increasing, the proportion of young operators who are unaccustomed to dealing with operational abnormalities has increased, which has caused problems in dealing with such operational abnormalities. In addition, when such an operator is educated and trained, it is most preferable to use an actual machine, but it cannot be frequently performed in order to maintain production efficiency.

  By the way, in the industrial field of a power generation / chemical plant, a training simulator is sometimes used for training an operator for work that is difficult to perform with an actual machine, such as plant operation. In these industrial simulators, heat exchange in the plant and material balance in the tank are modeled, and the response of the plant to disturbance signals resulting from the operation results and abnormalities of the operator is calculated. The calculation result of the plant response is displayed on a graph on the DCS device screen or an instrument device, and allows the operator to experience the same situation as the actual operation. Recently, as disclosed in Patent Document 1, there is also a technique for displaying an actual object with three-dimensional computer graphics by a virtual reality technique in order to increase the presence of an operator.

JP 2000-122520 A

  In such a power generation / chemical plant, the controlled object is a fluid, but is usually shielded in a pipe or a tank, and an operator does not visually observe the behavior of these fluids. Therefore, virtual reality technology and three-dimensional computer graphics are not used to express the behavior of the controlled object.

  On the other hand, in a continuous casting machine in the steel industry, etc., an operator observes the molten metal in the mold directly from its opening, and the injection is performed correctly, the molten metal flow is abnormal in the mold, or The occurrence of abnormal coagulation is monitored. Further, at the start of molten metal injection, it is also empirically determined whether or not the molten metal inflow amount matches the nozzle opening by the way the sparks scatter from the nozzle outlet. Therefore, in a simulator for the purpose of operation training in continuous casting, it is important to express a phenomenon related to molten steel that reflects normality or abnormality of the operation state, as in the case where an operator stands at a normal work position. That is, a manual operation training simulator for a continuous casting machine requires a unique function not found in a power generation / chemical plant simulator, which is a problem that cannot be solved by conventional plant operation training simulator technology.

  Therefore, the present invention visually reproduces the behavior of the molten metal or the phenomenon occurring around the molten metal supply device in the casting work training simulator of the continuous casting machine, and the problem of improving the judgment skill and control skill of the operator of the continuous casting machine. The purpose is to solve.

  The above-mentioned operation and gain of the present invention will be clarified from the following embodiments for carrying out the invention. Hereinafter, the present invention will be described based on embodiments shown in the drawings. However, the present invention is not limited to these embodiments.

FIG. 1 is a diagram showing a scene in which a trainer A is trained by a continuous casting casting training simulator apparatus 10 (hereinafter sometimes referred to as “simulator 10”) according to one embodiment. is there.
As can be seen from FIG. 1, the simulator 10 includes a casting speed input device 11, a nozzle opening manual input device 12, an arithmetic device 20, an image display device 13, a nozzle opening indicator 14, and a hot water level indicator 15. ing.

  The casting speed input device 11 is a means for setting the casting speed at which the simulation is performed, and is reflected in the calculation by the calculation device 20. Accordingly, the casting speed input device 11 is not particularly limited as long as it can input such conditions (information) to the arithmetic device 20, and examples thereof include a keyboard. The casting speed input means 11 can transmit information to the arithmetic unit 20 through an interface such as a signal input device.

  The nozzle opening manual input device 12 is an operation pendant which is the same type of nozzle opening manual input device as that used in actual operation in this embodiment. This makes it possible to perform training that is close to reality. That is, as can be seen from FIG. 1, the nozzle opening manual input device 12 has a push button switch 12a for generating a command (signal) for changing the nozzle opening in the opening direction, and a command for changing the nozzle opening in the closing direction ( A push button switch 12b for generating a signal). The nozzle opening manual input device 12 is configured to be able to transmit a signal according to the pressed state of the push button switches 12a and 12b to the arithmetic device 20 through an interface such as a signal input device.

  The calculation device 20 is a means for performing calculation processing necessary for simulation based on input information from the casting speed input device 11 and the nozzle opening manual input device 12 as calculation means. An example of this is an electronic computer. The specific operation to be performed will be described in detail later.

The video display device 13 is connected to the arithmetic device 20 as display means, and is a means for outputting the result as an animation (video) based on the calculation result by the arithmetic device 20. For example, a view of the continuous casting mold in operation as shown in FIG. The trainee operates the nozzle opening manual input device 12 in order to view this image and bring it closer to an appropriate state. As a result, operation training proceeds.
The video display device may be a so-called projector, which is a projection display device as in the present embodiment, or a display device. The display device may be formed integrally with the calculation means.

  The nozzle opening indicator 14 and the hot water level indicator 15 are also connected to the arithmetic unit 20 and display values output based on the calculation result by the arithmetic unit 20. It represents the level (height) of the surface. The opening degree and the surface level of the nozzle are values that the trainer refers to for operation.

  FIG. 2 shows a diagram representing the flow of simulation (S0) by the simulator 10. FIG. According to this, the casting speed which is a condition setting is set first (S1). This is performed by the casting speed input device 11 described above. After the initial setting, calculation is performed by the arithmetic device 20 based on the initial setting, and various displays are performed by the video display device 13, the nozzle opening indicator 14, and the hot water level indicator 15 (S2).

  Next, the trainee performs an operation that is considered appropriate based on the display displayed in S2 (S3). Specifically, the push button switches 12a and 12b of the nozzle opening manual input device 12 are pressed. As a result, the operation information is input to the computing device 20, and the computation is performed again based on this (S4). Then, the calculation results are sequentially displayed (S5).

  The trainee performs a more appropriate operation based on the display displayed in S5, and S3 to S5 are repeated. As a result, simulation images and various values are displayed in real time, and the trainee can train as if facing the actual device.

  Next, what kind of calculation is performed by the calculation device 20 will be described. FIG. 3 shows a flow (S100).

In the nozzle opening command calculation S101, calculation is performed to change the nozzle opening at a constant speed based on the state of each push button 12a, 12b of the nozzle opening manual input device 12 which is operation information of the manual device, and the result Are sequentially calculated for each processing cycle.
In the nozzle opening response calculation S102, the result of the calculation that the dead time delay acts on the nozzle opening command calculated in the nozzle opening command calculation S101 and the calculation that the primary delay acts on this result are added. Then, it is calculated sequentially for each processing cycle. The delay time of the dead time delay and the time constant of the primary delay are given as parameters in advance by measuring the actual machine.

  In the nozzle opening area calculation S103, a predetermined degree of nozzle clogging / melting loss is given by the parameter S104, and the substantial nozzle opening area is sequentially calculated for each processing cycle. FIG. 4 is a schematic diagram showing the adjustment of the nozzle opening area in an actual casting apparatus. The opening of the nozzle is hatched in FIG. Molten metal is supplied from here. The area of the opening B can be adjusted by moving the sliding plate 31 through the original nozzle opening 30. That is, the sliding plate 13 is provided with a hole 32 in a plate shape (plate). Then, the area of the opening B is changed by adjusting the degree of overlap between the nozzle opening 30 and the hole 31 by moving the plate in the direction of arrow C by the actuator 32. Therefore, in an actual casting apparatus, the actuator 32 is operated by operating the manual operation means. On the other hand, the simulator 10 formulates such a relationship in advance, and calculates the nozzle opening area based on this.

The nozzle clogging / melting loss parameter S104 is as follows. When the nozzle clogging parameter acts, as shown in FIG. 5A, the actual nozzle inner diameter shape K2 after the inclusion K3 is attached to the original nozzle inner diameter shape K1 indicated by the broken line is used. Depending on the degree of the inclusion K3, the inner diameter of the nozzle inner diameter shape K2 is reduced more uniformly than normal. Here, the opening area is calculated on the assumption that the opening diameter of the hole 32 (see FIG. 4) of the sliding plate 31 is the same as that in the normal state.
On the other hand, when the nozzle erosion parameter acts, as shown in FIG. 5 (b), K5 is used as the diameter of the slidable and widening with respect to the hole shape K4 of the original sliding plate indicated by the broken line. In this case, the holes of the sliding plate are expanded uniformly. Here, the opening area is calculated on the assumption that the nozzle inner diameter is the same as in the normal state.

  In the molten steel flow velocity calculation S105, based on the calculation formula based on the energy conservation law between the positional energy of the molten steel determined by the molten steel depth h in the bottom opening of the tundish 40 shown in FIG. 6 and the molten steel kinetic energy in the bottom opening, The flow rate of the molten steel at the nozzle opening is sequentially calculated for each processing cycle.

  The molten steel inflow calculation S106 adds the disturbance molten steel inflow due to the disturbance of the inflow to the product obtained by multiplying the calculation result of the nozzle opening area calculation S103 by the calculation result of the molten steel flow velocity calculation S105, and calculates the inflow of molten steel for each processing cycle. Are calculated sequentially. Here, the disturbance of the inflow amount of the disturbance molten steel inflow is a disturbance amount added to the irregularly changing molten steel inflow amount.

  The molten steel outflow calculation S107 calculates a product obtained by multiplying the opening area of the mold by the casting speed as the molten steel outflow from the mold. The casting speed is based on the value input by the casting speed input device 11 described above. In the molten steel outflow amount calculation S107, the calculation result of the molten steel outflow amount abnormality calculation S108 is considered. The molten steel outflow amount abnormality calculation S108 calculates the molten steel outflow amount from the opening formed by the fracture of the solidified shell in the mold and the molten steel outflow amount due to disturbance of the molten steel drawing due to fluctuations in the dummy bar drawing speed at the start of casting for each processing cycle. This is a value obtained by sequential calculation. Abnormal phenomena that cause molten steel outflow due to these disturbances are selected according to predetermined abnormal phenomenon parameters.

  Up to this point, the molten steel inflow and molten steel outflow have been calculated. Then, the molten steel surface height calculation S109 calculates the molten steel inflow / outflow balance difference between the molten steel inflow amount and the molten steel outflow amount as a fluctuation speed of the molten steel surface height, and a value obtained by sequentially integrating the fluctuation speed for each processing cycle. Is calculated as the hot water surface height.

  In the discharge flow calculation S110, the diameter of the molten steel discharge flow flowing from the discharge port and the drop point position on the molten metal surface are calculated based on the molten steel inflow amount calculated in the molten steel inflow amount calculation S106. In this embodiment, since it is difficult to determine the behavior of the discharge flow based on fluid dynamics in a short period of about the animation image display interval, the relationship between the molten steel discharge flow rate and the discharge flow diameter, and the discharge flow rate and the molten metal surface height The relationship between the discharge flow and the drop point position on the molten metal surface is stored as a numerical table, and the discharge flow diameter or the drop point position for an arbitrary discharge flow rate and molten metal surface height flow rate is calculated by interpolation processing.

  Splash generation calculation S111 is based on the distance between the discharge flow rate, the height of the discharge port, and the uppermost end of the dummy bar head, and the amount of splash generated per unit time and the amount of splash bounce. The average value is calculated. This calculation is performed using a model that is modeled so that the generation amount decreases as the molten steel accumulates in the mold, and the bounce height also decreases. In the present embodiment, the number of occurrences of splash and the bounce height are calculated for each calculation period of the mold peripheral image. The number of occurrences of splash within one calculation cycle is determined by generating random numbers based on a predetermined probability distribution having an average value of the product of the generation amount average value per unit time and the calculation cycle time. Similarly, the splash bounce height is determined by generating a random number based on a predetermined probability distribution in which the average bounce height is averaged.

  The spark generation amount calculation S112 calculates an average value of the spark generation amount per unit time based on the ratio of the portion where the discharge port is hidden by the molten metal surface, calculated from the discharge flow rate, the height of the discharge port, the opening area, and the molten metal surface height. Determine. Then, the number of sparks generated is irregularly calculated sequentially based on a predetermined probability distribution whose average value is the product of the generation amount average value and the calculation period.

  In the imaging process S113, an image for animation display is displayed at regular intervals based on the calculation results of the molten metal surface height calculation S109, the discharge flow calculation S110, the splash generation calculation S111, and the spark generation amount calculation S112. Is a process for generating This video is a video of the mold viewed from the trainee's point of view based on the positional relationship between the trainer and the mold given by parameters, etc., and the geometric layout of the mold peripheral equipment such as the immersion nozzle, tundish and control panel. . Here, a mold powder or the like may be drawn on the molten steel surface depending on an assumed operation state. Further, when the molten metal surface level is lowered, the color or flame of the molten steel may be displayed so that the boundary between the molten metal surface and the mold emits light.

Various necessary calculation results can be obtained by the flow S100 as described above. Then, the necessary ones of these values are provided to the trainer. Specifically, the video generated by the above-described imaging process is provided to the trainer via the video display device 13 as shown in FIG. The calculation result of the nozzle opening command calculation S101 is displayed on the nozzle opening indicator 14 as a signal based on a predetermined relational expression.
Further, the calculation result of the molten metal surface height calculation S109 is calculated by using the level measurement value as an output based on the relational expression of the first-order lag system that receives the molten metal surface position height as an input. Adjust the model parameters such as the measurement range of the molten metal level indicator and the origin of the measured value for the time constant of the first-order lag system according to the level indicator of the target continuous casting machine. In addition, a failure of the hot water level meter that occurs in actual operation may be simulated by giving appropriate parameters. As a result, it is possible to perform a simulation according to the proficiency level of the trainee. In this embodiment, a hot water level indicator is connected to the model computer via a signal output device, and the result of the sequential calculation of the hot water level meter output is displayed.

  It is desirable to install the same nozzle opening indicator and hot water level indicator as the actual machine from the viewpoint of education and training. However, the present invention is not limited to this, and it may be displayed by being included in the video.

  FIG. 7 shows a flow (S200) regarding what kind of calculation is performed by the calculation device in the simulator according to the second embodiment. Since the simulator in the second embodiment is common to the simulator 10 of the first embodiment except for the parts described below, only the differences will be described here. Further, in FIG. 7, the same reference numerals are used for portions common to FIG.

  In the flow S200, in addition to the flow S100, switching means (automatic control calculation S201) between manual control of the nozzle opening degree and automatic control for feeding back the molten metal surface level is provided. This enables training in response work when an abnormal phenomenon occurs in the automatic control state and work to switch to the molten metal level control in the steady casting state by automatic control after manual start of casting. In FIG. 7, the automatic control calculation S201 calculates the nozzle opening command based on the sequential PID control method and the like based on the calculation result of the molten metal surface height calculation S109 and the predetermined molten metal surface level. Manual control and automatic control can be selected by an operator using a push button switch or changeover switch.
