[0013] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below according to specific implementation modes and in combination with the accompanying drawings. Example

[0014] Figure 1A schematic flow chart of an optimization method for a refining furnace charging system provided in an embodiment of the present application. The method specifically comprises the following steps: Step S101: Obtain production data corresponding to a steel grade, and determine the type of material that needs to be added to the steel grade.

[0015] Specifically, according to the type of steel to be produced, the production data of the steel type is retrieved, wherein the production data includes the types of materials that need to be added when the steel type is produced in the LF refining furnace.

[0016] Step S102: screening the material categories in the refining furnace charging system, and setting the material category that needs to be added to the corresponding steel grade as the first category, and setting the material category that does not need to be added to the corresponding steel grade as the second category.

[0017] Specifically, the refining furnace charging system includes several types of materials that can be added, and different steel grades need to add different types of materials during the LF refining process. Therefore, after determining the material category required for the steel grade to be produced, all material categories in the refining furnace charging system can be screened, and the material category that needs to be added to the corresponding steel grade is set as the first category, and the material category that does not need to be added to the corresponding steel grade is set as the second category.

[0018] Step S103: setting a first label for the first category of materials in the refining furnace charging system, and setting a second label for the second category of materials in the refining furnace charging system.

[0019] Specifically, a "throw" label is set next to all first-category materials in the refining furnace charging system interface, and a "forbidden" label is set next to all second-category materials in the refining furnace charging system interface.

[0020] In addition, the indicator lights of all first-category materials in the refining furnace charging system interface are set to green, and the indicator lights of all second-category materials in the refining furnace charging system interface are set to red.

[0021] It should be noted that the above-mentioned "throw" label and "forbid" label are both located on the right side of the "manual setting amount" box of each material category in the refining furnace feeding system interface. The indicator light is located between the "manual setting amount" box of each material category and the "throw" label or "forbid" label.

[0022] Step S104: all second category materials in the refining furnace charging system are set to be disabled.

[0023] Specifically, all the material category options that do not need to be added in the concentrate furnace feeding system are set to disabled. In this way, even if the operator makes a setting error, these materials cannot be automatically fed.

[0024] It should be noted that in the refining furnace charging system, all operation buttons correspond to the control program in the PLC control system, that is, the charging control program can be started or stopped through the operation box on the operation interface. Example

[0025] Figure 2 The schematic diagram of the optimization system of the refining furnace charging system provided in the embodiment of the present application includes an acquisition module 201, a screening module 202, a label setting module 203 and a disabling module 204.

[0026] The acquisition module 201 is used to acquire the production data corresponding to the steel type and determine the type of material that needs to be added to the steel type.

[0027] The screening module 202 is used to screen the material categories in the refining furnace charging system, and set the material category that needs to be added to the corresponding steel grade as the first category, and set the material category that does not need to be added to the corresponding steel grade as the second category.

[0028] The label setting module 203 is used to set a first label for a first category of materials in the refining furnace charging system, and set a second label for a second category of materials in the refining furnace charging system.

[0029] It should be noted that the first label includes the "feed" label and a green indicator light set next to all first-category materials in the refining furnace charging system interface. The second label includes the "ban" label and a red indicator light set next to all second-category materials in the refining furnace charging system interface. Among them, the indicator light is located between the "manually set amount" box and the "feed" label or the "ban" label of each material category.

[0030] The disabling module 204 is used to set all the second category materials in the refining furnace charging system to be disabled.

[0031] Therefore, the technical solution of the present application avoids the wrong material addition during the automatic feeding process caused by operating errors by optimizing the operating interface and control system, making the composition of this type of steel more stable, improving the composition qualification rate, saving about 100,000 yuan per year, expanding the production of the type of steel, and improving economic benefits.

[0032] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
