Description

Technical Field

[0001] The invention relates to the field of industrial technology, and in particular to a converter steelmaking waste material feeding management method and system. Background Art

[0002] At present, the common scrap steel feeding in converter steelmaking is mostly done by the converter operator sending the scrap steel plan to the scrap steel workshop through the control system or verbally notifying the scrap steel workshop to prepare the materials. The scrap steel workshop then informs the scrap steel crane operator to load the materials according to the planned weight and type. There are many problems in the entire scrap steel preparation process: for example, in the case of verbal notification, the recipient is prone to mishearing or forgetting the information; it is impossible to control the preparation of various types of scrap steel in real time, which is prone to over- or under-supply; it is difficult to track problems; it is inconvenient to count materials; and it is impossible to grasp the real-time inventory information of scrap steel at any time. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a converter steelmaking waste charging management method and system.

[0004] The specific plan is as follows:

[0005] A method for managing the feeding of converter steelmaking waste comprises the following steps:

[0006] After receiving and displaying the scrap steel demand plan, the scrap steel workshop operation terminal receives the input trolley number and binds the trolley number with the scrap steel demand plan. After binding, the scrap steel demand plan and the bound trolley number are sent to the scrap steel overhead crane operation terminal;

[0007] After receiving the scrap steel demand plan and the bound trolley number, the scrap steel crane operation terminal displays the scrap steel types and the corresponding weight of each scrap steel included in the scrap steel demand plan, and displays the bound trolley number, so that the scrap steel crane operator can transport the scrap steel required in the scrap steel demand plan from the scrap steel area to the corresponding trolley;

[0008] A loading list corresponding to the trolley is constructed in the scrap steel workshop operation terminal. The loading list includes the actual performance data of each loading and unloading of the trolley. The actual performance data includes the weight and type of scrap steel loaded or unloaded.

[0009] The operation terminal of the scrap steel workshop periodically polls the real-time data of each scrap steel crane, and judges whether the scrap steel crane has material grabbing and material releasing actions according to the operation status data in the real-time data, and judges whether the scrap steel crane is loading and unloading the trolley in combination with the position in the real-time data; when it is judged that a scrap steel crane is loading or unloading a trolley, the corresponding performance data of the loading or unloading is added to the loading details table corresponding to the trolley;

[0010] The scrap steel workshop operation terminal periodically queries the loading list of the trolley bound to the scrap steel demand plan, and calculates the current weight of each type of scrap steel in all the scrap steel contained in the corresponding trolley based on the loading list, and sends the current weight of each type of scrap steel in all the scrap steel contained in the trolley to the scrap steel overhead crane operation terminal for display; at the same time, the scrap steel workshop operation terminal also determines whether the current weight of each type of scrap steel in all the scrap steel contained in the trolley meets the requirements of the scrap steel demand plan. If so, a scrap steel demand plan completion notification is generated and sent to the charging overhead crane operation terminal, and the corresponding trolley is controlled to move from the scrap steel workshop to the steelmaking workshop;

[0011] The charging crane operation terminal displays after receiving the notification of completion of the scrap steel demand plan, so that the charging crane operator can transport the scrap steel on the trolley bound to the corresponding scrap steel demand plan to the corresponding converter in the corresponding scrap steel demand plan.

[0012] Furthermore, the method for judging whether the scrap steel overhead crane has the action of grabbing and releasing the materials is as follows: judging whether the magnetic suction state signal of the scrap steel overhead crane has changed between the current polling and the last polling; when it changes from the suction state to the loose state, it is judged as the releasing action; when it changes from the loose state to the suction state, it is judged as the grabbing action; if the two states are consistent, it is judged as no action.

[0013] Furthermore, the charging list is bound to the scrap steel demand plan; when the scrap steel demand plan is generated, a charging list corresponding to the trolley bound to the scrap steel demand plan is constructed; when the scrap steel demand plan is completed, the corresponding charging list is cleared.

[0014] Furthermore, the method for determining the type of scrap steel in the performance data is as follows: when loading, the type of scrap steel is determined based on the scrap steel area number to which the scrap steel overhead crane is located during the adjacent grabbing; when returning, the type of scrap steel is determined based on the type of scrap steel during the last loading.

[0015] Furthermore, it also includes: after the scrap steel workshop operation terminal generates the scrap steel demand plan completion notification, it also includes synchronously sending it to the scrap steel overhead crane operation terminal; after the scrap steel overhead crane operation terminal receives the scrap steel demand plan completion notification, it cancels the display of relevant content corresponding to the scrap steel demand plan.

[0016] Furthermore, the charging crane adopts a double-hook crane, and its scrap steel transportation action is carried out by lifting the scrap steel trough on the trolley.

[0017] Furthermore, it also includes: when the charging crane operator completes the charging, the charging crane operation terminal sends a charging completion notification to the scrap steel workshop operation terminal. After receiving the charging completion notification, the scrap steel workshop operation terminal controls the corresponding trolley to move from the steelmaking workshop to the scrap steel workshop.

[0018] A converter steelmaking scrap charging management system comprises a scrap steel workshop operation terminal, a scrap steel overhead crane operation terminal and a charging overhead crane operation terminal. The system implements the steps of the above method in an embodiment of the present invention.

[0019] The present invention adopts the above technical scheme, and can track the preparation and charging of scrap steel according to the scrap steel type and planned weight according to the scrap steel demand plan of the converter furnace, thereby realizing the automated management of the charging of scrap steel in the converter. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 Shown is a schematic diagram of a converter steelmaking working scene in Embodiment 1 of the present invention. DETAILED DESCRIPTION

[0021] To further illustrate various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in this field should be able to understand other possible implementations and advantages of the present invention.

[0022] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0023] Embodiment 1:

[0024] The embodiment of the present invention provides a method for managing the feeding of waste materials from converter steelmaking, such as Figure 1 As shown, the method comprises the following steps:

[0025] S1: After the scrap steel workshop operation terminal receives and displays the scrap steel demand plan, it receives the input trolley number and binds the trolley number with the scrap steel demand plan. After binding, the scrap steel demand plan and the bound trolley number are sent to the scrap steel overhead crane operation terminal.

[0026] The scrap steel demand plan is generated by the staff of the steelmaking workshop (such as the converter operator) according to the demand. The scrap steel demand plan needs to include the number of the required converter, the type of scrap steel required and the weight of each type of scrap steel.

[0027] like Figure 1 As shown, the scrap steel workshop operation terminal can be set in the scrap steel main control room, and is used for the staff in the scrap steel main control room to uniformly manage the scrap steel preparation. The scrap steel workshop operation terminal can be a common PC, or other forms of equipment with a controller, memory, display module and input module.

[0028] After the staff in the scrap steel main control room checks the scrap steel demand plan displayed on the scrap steel workshop operation terminal, they enter the trolley number that needs to be bound.

[0029] S2: After the scrap steel crane operating terminal receives the scrap steel demand plan and the bound trolley number, it displays the types of scrap steel included in the scrap steel demand plan and the corresponding weight of each type of scrap steel, and also displays the bound trolley number, so that the scrap steel crane operator can transport the scrap steel required in the scrap steel demand plan from the scrap steel area to the corresponding trolley.

[0030] The scrap crane operation terminal is located on the scrap crane for the scrap crane operator to view information. When the scrap crane operation terminal displays the scrap steel types and the corresponding weight of each scrap steel included in the scrap steel demand plan, the scrap crane operator can know that the scrap steel needs to be grabbed from the scrap steel placed in the scrap steel area corresponding to the scrap steel type, and from the bound trolley number displayed on the scrap crane operation terminal, it can be known that the grabbed scrap steel needs to be released on the trolley.

[0031] S3: Construct a loading list corresponding to the trolley in the scrap steel workshop operation terminal. The loading list includes the performance data of each loading and unloading of the trolley. The performance data includes the weight of the scrap steel loaded or unloaded and the type of scrap steel.

[0032] It should be noted that the loading list corresponds to the trolley one by one. The loading list is bound to the scrap steel demand plan. When the scrap steel demand plan is generated, the loading list corresponding to the trolley bound to the scrap steel demand plan is constructed; when the scrap steel demand plan is completed, the corresponding loading list is cleared.

[0033] The actual performance data of each loading and unloading of the trolley is recorded in chronological order in the loading details table. The weight of the scrap steel for loading or unloading can be determined based on the weight of the trolley before and after loading or unloading (the trolley includes a weighing instrument). The type of scrap steel can be determined based on the scrap steel area number to which the scrap steel overhead crane is located during the adjacent grabbing. Since when multiple types of scrap steel are required, it is assumed that one type of scrap steel will be grabbed before another type of scrap steel. In this way, if a certain type of scrap steel is found to exceed the required weight of the scrap steel after the last loading, then it is necessary to unload the scrap steel. In this way, it can be considered that the type of scrap steel when unloading is the same as the type of scrap steel when loading last time.

[0034] S4: The operation terminal of the scrap steel workshop periodically polls the real-time data of each scrap steel crane, and determines whether the scrap steel crane has material grabbing and releasing actions based on the operating status data in the real-time data, and determines whether the scrap steel crane is loading and unloading materials to the trolley in combination with the position in the real-time data; when it is determined that a scrap steel crane is loading or unloading materials to a certain trolley, the corresponding performance data of the loading or unloading is added to the loading details table corresponding to the trolley.

[0035] The operating status data in the real-time data used in this embodiment is that the scrap steel overhead crane has a magnetic suction status signal. The scrap steel workshop operation terminal only needs to determine whether the magnetic suction status signal has changed between the current polling and the last polling. If it changes from the suction state to the loose state, it is judged as a material discharge action, otherwise it is a material grabbing action; if the two states are consistent, it is considered that there is no action and no processing is required.

[0036] Based on the acquired position, it can be determined whether the scrap crane is grabbing or unloading materials above the trolley or above the scrap steel area. Grabbing or unloading materials above the scrap steel area and other areas other than above the trolley are considered as empty operations, misoperations, or cleaning of scrap steel on the ground, and these situations are ignored.

[0037] S5: The scrap steel workshop operation terminal periodically queries the loading list of the trolley bound to the scrap steel demand plan, and calculates the current weight of each type of scrap steel in all the scrap steel contained in the corresponding trolley based on the loading list, and sends the current weight of each type of scrap steel in all the scrap steel contained in the trolley to the scrap steel overhead crane operation terminal for display; at the same time, the scrap steel workshop operation terminal also determines whether the current weight of each type of scrap steel in all the scrap steel contained in the trolley meets the requirements of the scrap steel demand plan. If so, a scrap steel demand plan completion notification is generated and sent to the charging overhead crane operation terminal, and the corresponding trolley is controlled to move from the scrap steel workshop to the steelmaking workshop.

[0038] The scrap crane operator can adjust the operation in time based on the current weight of each type of scrap steel displayed on the scrap crane operation terminal. For example, when the current weight of a certain type of scrap steel exceeds the required weight, the material is returned; when a certain type of scrap steel just reaches the required weight, the next type of scrap steel is grabbed.

[0039] like Figure 1 As shown, the working area of ​​the charging crane is the steelmaking workshop, which is used to grab scrap from the trolley and transport it to the steelmaking converter.

[0040] The charging crane operation terminal is located on the charging crane for the charging crane operator to view information.

[0041] In this embodiment, the trolley can travel on the corresponding scrap steel trolley track to transfer between the scrap steel workshop and the steelmaking workshop. When the scrap steel demand plan is completed, the corresponding trolley is controlled to move from the scrap steel workshop along the scrap steel trolley track to the steelmaking workshop.

[0042] Furthermore, after the scrap steel workshop operation terminal generates the scrap steel demand plan completion notification, it also includes synchronously sending it to the scrap steel overhead crane operation terminal; after the scrap steel overhead crane operation terminal receives the scrap steel demand plan completion notification, it cancels the display of relevant content corresponding to the scrap steel demand plan.

[0043] S6: After receiving the notification of completion of the scrap steel demand plan, the charging crane operation terminal displays it, so that the charging crane operator can transport the scrap steel on the trolley bound to the corresponding scrap steel demand plan to the corresponding converter in the corresponding scrap steel demand plan.

[0044] In this embodiment, the charging crane adopts a double-hook crane, which can lift the scrap steel tank on the trolley. In the specific implementation, after the charging crane operator checks the scrap steel demand plan completion notification, he operates the charging crane to move to the stop position after the corresponding trolley moves to the steelmaking workshop, then lifts the scrap steel tank on the trolley, and transports the scrap steel tank to the converter for charging.

[0045] Furthermore, when the operator of the charging crane completes the charging, he puts the empty scrap steel tank back into the corresponding trolley. At this time, the charging crane operation terminal sends a charging completion notification to the scrap steel workshop operation terminal. After receiving the charging completion notification, the scrap steel workshop operation terminal controls the corresponding trolley to move from the steelmaking workshop to the scrap steel workshop.

[0046] The embodiment of the present invention achieves the purpose of online tracking of scrap steel feeding, which is beneficial for overhead crane personnel to load materials according to plan. Management personnel can grasp the material usage and cost analysis in real time, improve feeding efficiency, and save scrap steel costs.

The system implements the steps in the above method embodiment of embodiment 1 of the present invention.

[0049] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
