[0072] Through extensive research, the inventors discovered that current methods for refining steel in LF furnaces aim to reduce power consumption while adding steel bars. However, although existing methods reduce power consumption, the steel-to-growth ratio remains relatively high.

[0073] In view of the above-mentioned problems, this embodiment provides a refining method, apparatus, electronic equipment, and storage medium. It can determine the current first headroom, current first temperature, and current first component content of the LF furnace by determining a production plan. Based on the production plan, it determines the unit time for charging the converter, the furnace steel processing time, the programmed time, and the soft blowing time. The programmed time includes sampling time, temperature measurement time, and slag addition time. Based on the soft blowing time and furnace steel processing time, it determines the first maximum charging weight for the rebar ends. Based on the first headroom, first temperature, and first component content, it determines the second headroom, second temperature, and second component content after adding the first maximum charging weight to the LF furnace. It calculates the first difference between the first headroom and the second headroom, and the second difference between the first temperature and the second temperature. When the first difference, the second difference, and the second component content all meet the discharge conditions, LF refining is performed with the first maximum charging weight. When any of the first difference, the second difference, or the second component content does not meet the discharge conditions, the first maximum charging weight is adjusted. This allows for the addition of the maximum number of rebar ends within a limited time, thereby reducing the steel ratio. The solution provided in this embodiment is described in detail below.

[0074] This embodiment provides an electronic device. In one possible implementation, the electronic device can be a user terminal. For example, the electronic device can be, but is not limited to, a server, a smartphone, a personal computer (PC), a tablet computer, a personal digital assistant (PDA), or a mobile internet device (MID).

The electronic device 100 may further include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown. Figure 1 The components shown can be implemented using hardware, software, or a combination thereof.

[0076] The electronic device 100 includes a refining apparatus 110, a memory 120, and a processor 130.

[0077] The components of the memory 120 and processor 130 are electrically connected directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines. The refining apparatus 110 includes at least one software function module that can be stored in the memory 120 in the form of software or firmware or embedded in the operating system (OS) of the electronic device 100. The processor 130 is used to execute the executable modules stored in the memory 120, such as the software function modules and computer programs included in the refining apparatus 110.

[0079] Please refer to Figure 2 , Figure 2 For application Figure 1 The flowchart of a refining method for an electronic device 100 is shown below, and the method includes a detailed description of each step.

[0080] Step 201: Determine the production plan.

[0081] Step 202: Determine the current first headroom, current first temperature, current first molten steel weight, and current first composition content of the LF furnace.

[0082] Step 203: Determine the unit time for adding steel bars to the converter, the furnace steel processing time, the program time, and the soft blowing time based on the production plan.

[0083] The program time includes sampling time, temperature measurement time, and slag addition time.

[0084] Step 204: Determine the first maximum feed weight for the rebar head based on the soft blowing time and furnace steel processing time.

[0085] Step 205: Based on the first headroom, first temperature, first molten steel weight, and first component content, determine the second headroom, second temperature, and second component content after adding the first maximum charge weight to the LF furnace.

[0086] Step 206: Calculate the first difference between the first clearance and the second clearance.

[0087] Step 207: Calculate the second difference between the first temperature and the second temperature.

[0088] Step 208: When the first difference, the second difference, and the content of the second component all meet the exit conditions, LF refining is carried out with the first maximum feed weight.

[0089] Step 209: If any of the first difference, the second difference, or the content of the second component does not meet the exit conditions, adjust the first maximum feed weight.

[0090] For example, based on the production plan, the processing time of the furnace steel is known, and the unit time, program time, and soft blowing time for adding steel bars are determined. When the furnace steel processing time is 28 minutes, the soft blowing time is 6 minutes, the sampling time, temperature measurement time, and the program time consisting of adding slag are 4 minutes, and the unit time for adding steel bars is one ton of steel bars every 2 minutes, the first maximum feeding weight is calculated as (28-6) / 2 = 11 tons.

[0091] If the current first clearance of the LF furnace is 8 layers of bricks (each layer is 10 cm high), and the molten steel level rises by 1 layer of bricks for every 3 tons of rebar added, then adding the first maximum rebar weight of 11 tons to the LF furnace will raise the molten steel level by 11 / 3 = 3.67 layers of bricks. Adding the expected slag thickness of 10 cm, the second clearance of the LF furnace will be 8 - 3.6 - 1 = 3.33 layers of bricks.

[0092] When the initial temperature of the LF furnace is 1565℃, adding one ton of rebar to the LF furnace lowers the temperature by 12℃. Therefore, adding 11 tons of rebar will lower the temperature of the LF furnace by 11*12=132℃. Adding slag and alloy during refining lowers the temperature by 10℃, for a total temperature drop of 142℃. During the refining process, high-level power supply is used. Based on power supply level 8, and considering the furnace steel processing time, soft blowing time, and program time, the maximum power supply time is determined to be 18 minutes. Based on power supply level 8, the temperature rises by 8℃ per minute, so the temperature rise in 18 minutes is 18*8=144℃. When the LF furnace reaches the outlet, the second temperature of the LF furnace is 1565-142+144=1567℃.

[0093] The composition of the reinforcing bar ends includes: carbon, silicon, manganese, phosphorus, and sulfur. Based on the current weight of the first batch of molten steel in the LF furnace and the current composition of the first component in the LF furnace, the composition of the second component in the LF furnace is calculated after adding the first maximum charge weight of reinforcing bar ends.

[0094] The first clearance, first temperature, and first component content of the LF furnace before adding the first maximum weight of reinforcing steel head are compared with the second clearance, second temperature, and second component content after adding the first maximum weight of reinforcing steel head to determine whether the exit conditions are met. If they are met, LF refining is carried out according to the first maximum weight of reinforcing steel head. If they are not met, the first maximum weight of reinforcing steel head is adjusted, and LF refining is carried out based on the adjusted first maximum weight of reinforcing steel head.

[0095] There are multiple ways to determine whether the first difference, the second difference, and the second component all satisfy the exit conditions. In one implementation, such as... Figure 3 As shown, it includes the following steps:

[0096] Step 208-1: Compare the first difference with the preset clearance.

[0097] Step 208-2: When the first difference is greater than or equal to the preset clearance, determine whether the second difference is greater than zero.

[0098] Step 208-3: If the second difference is greater than zero, compare each sub-component in the second component with its corresponding component threshold.

[0099] Step 208-4: When each sub-component is greater than or equal to the corresponding component threshold, determine that the first difference, the second difference, and the second component all meet the exit conditions, and perform LF refining with the first maximum feed weight.

[0100] The first difference is compared with the preset clearance. If the first difference is greater than or equal to the preset clearance, it indicates that the LF furnace meets the safety standards. Another way to determine whether the first difference meets the exit conditions is to compare the second clearance with the safety standard clearance. If the second clearance is greater than or equal to the safety standard clearance, it is determined whether the second difference is greater than zero. If the second difference is greater than zero, it is determined whether each sub-component in the second component content meets the corresponding component threshold. For example, it is determined whether carbon meets the carbon component threshold, silicon meets the silicon component threshold, manganese meets the manganese component threshold, phosphorus meets the phosphorus component threshold, and sulfur meets the sulfur component threshold. If all the above elements meet the corresponding component thresholds, then LF refining is carried out according to the first maximum feed weight.

[0101] The method for determining the content of the second component after adding the first maximum feed weight to the LF furnace based on the content of the first component can be as follows: Figure 4 As shown, it includes the following steps:

[0102] Step 301: Determine the content of the third component for the first maximum feed weight.

[0103] Step 302: Based on the content of the first component and the content of the third component, determine the content of the second component after adding the first maximum feed weight to the LF furnace.

[0104] Calculate the third component content of carbon, silicon, manganese, phosphorus and sulfur in the first maximum added weight of the steel bar head, and determine the first component content of carbon, silicon, manganese, phosphorus and sulfur in the first component content.

[0105] Taking the second component content of carbon as an example, based on the third component content and the first component content of carbon, the second component content of carbon is calculated.

[0106] To improve the accuracy of determining the first maximum feed weight of the rebar head, such as Figure 5 As shown, it includes the following steps:

[0107] Step 401: Determine the maximum power supply time based on the furnace steel processing time, soft blowing time, and program time.

[0108] Step 402: Determine the amount of carbon added to the electrode during the longest power supply time.

[0109] Step 403: Add the carbon content in the second component content to the carbon addition amount in the electrode to obtain the final carbon content in the second component content.

[0110] Step 404: When all components except carbon in the second component content are greater than or equal to the corresponding component threshold, compare the final carbon content with the corresponding threshold.

[0111] Step 405: When the final carbon content is greater than or equal to the corresponding threshold, determine that the first difference, the second difference, and the second component all meet the exit conditions, and perform LF refining with the first maximum feed weight.

[0112] During the LF refining process, due to the need for a power supply throughout the process, electrode carbon increase occurs during power supply. The carbon increase is 0.01% every 10 minutes, with a maximum power supply time of 18 minutes, resulting in a carbon increase of approximately 0.02%. The final carbon content is obtained based on the second component content of the carbon component after adding the first maximum feed weight and the electrode carbon increase. For the second component content, the second component content of other sub-components besides the carbon element content is compared with the corresponding component threshold. For the comparison of the carbon element in the second component content, the final content is compared with the component threshold of the carbon element. When both are greater than the corresponding component threshold, LF refining is carried out with the first maximum feed weight.

[0113] In the LF refining process based on the first maximum feed weight, such as Figure 6 As shown, it includes the following steps:

[0114] Step 501: Real-time detection of the amount of rebar added.

[0115] Step 502: Compare the added amount with multiple preset flow rates.

[0116] Step 503: Determine the target flow that matches the added flow from multiple preset flow rates.

[0117] Step 504: Stir the added steel bar head based on the target flow rate.

[0118] For example, when the amount added is less than or equal to 3 tons, argon gas at a rate of 30 cubic meters per hour is used for stirring; when the amount added is 3-5 tons, argon gas at a rate of 35 cubic meters per hour is used for stirring; when the amount added is 5-7 tons, argon gas at a rate of 40 cubic meters per hour is used for stirring; and when the amount added is 7-9 tons, argon gas at a rate of 50 cubic meters per hour is used for stirring.

[0119] Existing technologies typically use a relatively fixed flow rate of argon gas for stirring, resulting in poor refining effects. Based on the LF refining power supply level, a second difference can be compared with multiple preset temperatures. From these preset temperatures, a target temperature matching the second difference can be determined, and the target power supply level corresponding to the target temperature can be identified. Power is then supplied to the LF furnace based on the target power supply level.

[0120] For example, when the second difference is 17°C, the target power supply level corresponding to 17°C is determined to be level 8; when the second difference is less than 5°C, the target power supply level corresponding to the second difference is determined to be level 2. The heating temperature of level 8 is greater than that of level 2.

[0121] During the continuous addition of steel rebar ends, to ensure that the refining quality is not affected when adding the first maximum weight of steel rebar ends, refer to... Figure 7 This includes the following steps:

[0122] Step 601: During the process of adding the steel bar ends into the LF furnace, the color of the slag is detected in real time.

[0123] Step 602: When the slag color is the first preset color, determine the amount of steel bar ends to be added and the first preset amount of lime to be added.

[0124] Step 603: Calculate the first product of the added amount and the first preset amount of lime to be added, and use it as the first amount of lime to be added, and add lime to the LF furnace based on the first amount of lime to be added.

[0125] Step 604: When the color of the slag is the second preset color, determine the second preset amount of lime to be added, wherein the second preset amount of lime to be added is greater than the first preset amount of lime to be added.

[0126] Step 605: Calculate the second product of the added amount and the second preset amount of lime to be added, and use it as the second amount of lime to be added, and add lime to the LF furnace based on the second amount of lime to be added.

[0127] Step 606: When the color of the slag is the third preset color, determine the third preset amount of lime to be added, wherein the third preset amount of lime to be added is greater than the second preset amount of lime to be added.

[0128] Step 607: Calculate the third product of the added amount and the third preset amount of lime to be added, and use it as the third amount of lime to be added, and add lime to the LF furnace based on the third amount of lime to be added.

[0129] For example, if the slag color is a first preset color, which is light green, it indicates that the rebar ends are slightly rusted, and the first preset amount of lime to be added is 15 kg / ton. The first preset amount of lime to be added is the amount of lime to be added per ton of rebar ends. Calculate the product of the amount of rebar ends added to the LF furnace and 15 kg / ton, and add the lime of the first product to the LF furnace.

[0130] When the slag color is the second preset color, which is dark green, it indicates that the rebar ends have moderate rust. The second preset amount of lime to be added is 17 kg / ton, which is the amount of lime to be added per ton of rebar ends. Calculate the product of the amount of rebar ends added to the LF furnace and 17 kg / ton, and add the lime of the second product to the LF furnace.

[0131] When the slag color is the third preset color, which is black, it indicates that the rebar ends are severely rusted. The required third preset lime addition is 19 kg / ton, which is the amount of lime added per ton of rebar ends. Calculate the product of the amount of rebar ends added to the LF furnace and 19 kg / ton, and add the lime from this third preset product to the LF furnace.

[0132] Please refer to Figure 8 This application embodiment also provides an application for Figure 1The refining apparatus 110 of the electronic device 100 includes:

[0133] The first determining module 111 is used to determine a production plan, including the current first headroom, current first temperature, current first molten steel weight, and current first component content of the LF furnace; based on the production plan, it determines the unit time for adding rebar heads to the converter, the furnace steel processing time, the programmed time, and the soft blowing time, wherein the programmed time includes sampling time, temperature measurement time, and slag addition time; based on the soft blowing time and the furnace steel processing time, it determines the first maximum weight of rebar heads to be added; and based on the first headroom, first temperature, first molten steel weight, and first component content, it determines the second headroom, second temperature, and second component content after adding the first maximum weight of rebar heads to the LF furnace.
