Detailed Description
The embodiment of the application solves the technical problems of steel stacking accidents or equipment damage caused by the state of a safety pin in the prior art by providing a rolling mill feeding control method, a rolling mill feeding control device, rolling mill feeding control equipment and rolling mill feeding control media.
The technical scheme of the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
starting a rolling mill, and triggering a loop of the rolling mill to start to act; judging whether the angle of the rolling mill looper action is larger than a preset critical angle or not; if so, determining that the shear pin has been pulled from the mill loop, allowing an intermediate billet to enter the mill; if not, determining that the safety pin is not pulled out of the rolling mill loop, and prohibiting the intermediate billet from entering the rolling mill.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The embodiment provides a rolling mill feeding control method, as shown in fig. 1, comprising:
step S101, starting a rolling mill, and triggering a loop of the rolling mill to start to act;
step S102, judging whether the angle of the rolling mill looper action is larger than a preset critical angle or not;
step S103, if yes, determining that the safety pin is pulled out of the rolling mill loop, and allowing an intermediate blank to enter the rolling mill;
if not, determining that the safety pin is not pulled out of the rolling mill loop, and prohibiting the intermediate billet from entering the rolling mill.
It should be noted that the method for controlling the feeding of the rolling mill can be applied to a computer, a monitor and other independent computing devices, or can be a computing module integrated on a production line, and the like, and is not limited herein.
The following describes in detail the implementation steps of the method provided in this embodiment with reference to fig. 1:
first, step S101 is executed, the rolling mill is started, and the rolling mill looper is triggered to start to act. In a hot-rolled strip steel production line, steel rolling equipment is frequently overhauled or faults between frames are frequently overhauled, and in the period, in order to ensure the safety of operators, a safety pin is inserted into a loop of a rolling mill, so that the false action of the loop is prevented from hurting people. However, after the maintenance or the fault treatment between the frames is finished, because the number of the loops is more than one, the phenomenon that a safety pin of a certain loop is forgotten to be pulled out often occurs, so that the loop cannot act during rolling production, and a steel stacking accident is caused. In view of the above, the inventor of the present application proposes a solution provided by the embodiment of the present application, that is, before the maintenance is finished and normal production is resumed, the state of the loop safety pin is checked first, so as to avoid steel stacking accidents or equipment damage caused by the fact that the safety pin is not pulled out. Further, the project is added to a production process as automatic detection, and is used as an essential step in the production process, so that automatic detection after overhaul is realized, missed detection caused by adopting a manual inspection mode is avoided, the fool-proof effect is achieved, and meanwhile, the workload of operators can be reduced. In a specific implementation process, before normal production is restored, the rolling mill is started, and the loop of the rolling mill is triggered to start to act, so that the state of the safety pin can be judged according to the angle of the loop. Of course, other means may be used to trigger the start of the mill loop, such as opening the mill loop alone, etc., without limitation.
Then, step S102 is executed to determine whether the angle of the rolling mill loop is greater than a preset critical angle. In a specific implementation process, the number of rolling mill loops is N, where N is a natural number greater than or equal to 1, for example, 5 or 6 rolling mill loops, and the number of rolling mill loops varies according to the configuration of the rolling mill, which is not limited in the present application. When judging whether the angles of the rolling mill loopers are larger than a preset critical angle, judging whether the angles of the N rolling mill loopers are all larger than the preset critical angle. In a specific implementation, the preset critical angle may be 17 ° to 19 °, and preferably, the preset critical angle may be 18 °. This is because the maximum angle at which the mill loop can move is 17 deg. to 19 deg. when the shear pin on the mill loop is not pulled out, so that the shear pin can be considered to have been pulled out from the mill loop when the angle at which the mill loop is operated is greater than that interval. Of course, in a specific embodiment, the preset critical angle may also be other values, such as 18 ° to 20 °, according to the rolling mill model, etc., which is not limited by the present application.
Finally, step S103 is performed, if yes, determining that the safety pin has been pulled out of the mill loop, allowing the intermediate billet to enter the mill; if not, determining that the safety pin is not pulled out of the rolling mill loop, and prohibiting the intermediate billet from entering the rolling mill. In a specific implementation process, when judging that the angles of N rolling mill loopers are all larger than a preset critical angle, determining that the safety pin is pulled out of the rolling mill loopers, allowing the intermediate blank to enter the rolling mill, if judging that at least one rolling mill loopers does not reach the preset critical angle, determining that the safety pin is not pulled out of the rolling mill loopers, and prohibiting the intermediate blank from entering the rolling mill, so that production can be prohibited in time under the condition that the safety pin is not pulled out, and steel stacking accidents or equipment damage caused by the safety pin is avoided.
Further, after the fact that the safety pin is not pulled out of the loop of the rolling mill and the intermediate billet is forbidden to enter the rolling mill is determined, the application further provides a lighting and/or sounding sound-light warning lamp so as to prompt an operator to timely check the state of the safety pin. In addition, the safety pin is also arranged at a position of displaying the safety pin which is not pulled out on the control interface so as to assist an operator to check the state of the safety pin, wherein the control interface can be a man-machine interaction interface or a computer display interface and the like, and the safety pin is not limited herein. Specifically, a simulation diagram of the hot-rolled strip production line is arranged on the control interface, and the simulation diagram corresponds to the real hot-rolled strip production line one by one and can reflect the currently-proceeding process steps in real time. When judging that the safety pin is not pulled out of the rolling mill loop, the position of the safety pin which is not pulled out can be displayed on the control interface so as to help operators to quickly locate the problem point, so that the safety pin can be correspondingly processed, the overhaul efficiency is improved, and the production utilization rate is further improved.

The device may be a computer, a monitor or other independent computing device, or may be a computing module integrated on a production line, which is not limited herein.
In a specific implementation process, the processing module 203 is further configured to light and pull the audible and visual alarm lamp, so as to prompt an operator to check the status of the safety pin in time, or is configured to display the position of the unplugged safety pin on the man-machine interaction system, so as to assist the operator to check the status of the safety pin quickly.
