[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0054] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily need to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0055] It should also be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such uses of these terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described.

[0056] See Figure 1 This is a schematic diagram of the structure of the heating furnace according to an embodiment of this application.

[0057] like Figure 1 As shown, the heating furnace can be a pulse heating furnace 1. The two sides of the pulse heating furnace 1 are respectively the mill side (i.e. the side where the mill is located) and the non-mill side. The mill side and the non-mill side are arranged opposite to each other, and the mill side and the non-mill side are respectively provided with multiple burners. For example, the mill side is provided with multiple first burners 2, and the non-mill side is provided with multiple second burners 3. Each first burner 1 and each second burner 2 are arranged opposite to each other.

[0058] It is understandable that in a pulse-jet furnace, the independent control of the burners on both sides may result in uneven temperatures, with one burner reaching a higher temperature than the other. To ensure heating quality along the length of the slab, i.e., uniform temperature, the furnace chamber must also be uniform, meaning the heating temperature of the burners on both sides should be uniform. However, during the actual heating process, deviations in burner pressure and other factors can cause the flame to exceed the preset length, leading to a higher temperature on one side of the furnace and resulting in uneven temperatures on both sides.

[0059] Based on the above, see Figure 2 This is a flowchart illustrating a control method for a multi-burner furnace according to an embodiment of this application. The control method for the multi-burner furnace allows the temperature difference between the two sides of the furnace to be controlled within a preset range, improving the temperature uniformity along the length of the slab and thus enhancing the quality of the steel coil.

[0060] The control method of the multi-burner heater will be described in detail below.

[0061] like Figure 2 As shown, according to a first aspect of the embodiments of this application, a control method for a multi-burner heating furnace is provided, the method including but not limited to steps S101 to S103:

[0062] Step S101. Obtain the first load of the first burner and the second load of the second burner;

[0063] It is understood that the heating furnace is typically divided into multiple heating sections, including but not limited to a preheating section, a first heating section, a second heating section, and a matrix section. The preheating section is used for initial heating of the slab at a relatively low temperature. The first and second heating sections involve multiple heating cycles of the steel coil to ensure process quality. The matrix section is used to ensure that the surface and center temperatures of the slab are consistent. It should be noted that each heating section includes multiple first burners and multiple second burners arranged opposite each other, for example, 8-10 first or second burners, each arranged opposite to the other. Furthermore, to improve control precision and reduce energy consumption, the pulse of the pulse-type heating furnace is typically controlled by zones. Each heating section may be divided into multiple heating zones, each of which may include one burner, two burners, etc.

[0064] Based on the above, obtaining the first load of the first burner can be: obtaining the first load of one or more first burners in each heating zone, obtaining the first load of one or more first burners in each heating section, obtaining the first load of one or more first burners on the mill side of the heating furnace, etc. The specific selection depends on the temperature control requirements and is not limited here.

[0065] It is understandable that the principle of obtaining the second load of the second burner is the same as that of the first burner, and will not be repeated here.

[0066] In some embodiments of step S101, based on the foregoing scheme, obtaining the first load of the first burner includes:

[0067] Step S1011. Obtain the detected temperature of the first burner, and obtain the target temperature difference between the detected temperature and the preset temperature;

[0068] It is understandable that the temperature of the first burner can be detected by a heat detection device located on one side of the first burner, for example, by a pyrometer.

[0069] The preset temperature refers to the theoretical combustion temperature of the first burner, at which the first burner can achieve the best effect.

[0070] Step S1012. Based on the preset mapping relationship, obtain the first load of the first burner according to the target temperature difference.

[0071] It is understandable that after obtaining the target temperature difference, the difference between the actual combustion temperature and the theoretical combustion temperature of the first burner can be known. Based on the preset mapping relationship, the first load corresponding to the target temperature difference can be known. For example, when the difference between the actual combustion temperature and the theoretical combustion temperature is 10, the first load is 80% of the theoretical load. The theoretical load refers to the load of the first burner at the theoretical combustion temperature.

[0072] In some embodiments of step S1012, based on the aforementioned scheme and a preset mapping relationship, the first load of the first burner is obtained according to the target temperature difference, including:

[0073] Obtain a preset mapping table, which records the correspondence between each temperature difference value and each load value;

[0074] Find the first load value that matches the target temperature difference in the mapping table.

[0075] Understandably, by pre-constructing a mapping table to record the correspondence between various temperature differences and various load values, when a specific target temperature difference is obtained, the corresponding load value can be quickly located by looking up the table, simplifying the calculation process. For example, there may be preset ratios between various temperature differences and various load values, such as 1, 10, 20, etc., which are not limited here. Based on these ratios, a correspondence between various temperature differences and various load values ​​can be established.

[0076] In some embodiments of step S1012, based on the aforementioned scheme and a preset mapping relationship, the first load of the first burner is obtained according to the target temperature difference, including:

[0077] Obtain a preset mapping function, which is used to characterize the functional relationship between each temperature difference and each load.

[0078] Based on the target temperature difference, the first load of the first burner is calculated using the mapping function.

[0079] It is understood that the mapping function refers to a mapping function constructed with each temperature difference as the independent variable and each load as the dependent variable. For example, the mapping function can be f(x,y), where x and y can be each temperature difference and each load, respectively. When each temperature difference is determined, each load can be calculated according to the mapping function.

[0080] Step S102. Obtain the load deviation based on the first load and the second load;

[0081] As can be seen from the above, the first load refers to the load of the first burner on one side of the heating furnace, and the second load refers to the load of the second burner on the opposite side of the heating furnace. Since the first and second burners are arranged opposite each other, by calculating the load deviation between the first and second loads, it can be determined whether the working states of the first and second burners are consistent. Ideally, in order to ensure uniform heating and slab quality, the working states of the first and second burners should be consistent. However, as mentioned above, due to deviations such as flame jet pressure, the flame from one burner is jetted to the other burner, causing the combustion temperature of the other burner to be greater than that of the first burner, thus resulting in the aforementioned load deviation.

[0082] Step S103. If the load deviation is greater than or equal to a preset deviation threshold, then control the first burner and the second burner to output at a target average value, where the target average value is the average of the first load and the second load.

[0083] It is understood that the deviation threshold refers to the maximum allowable deviation in load between the first burner and the second burner, for example, set to 20. That is, when the load deviation is greater than the deviation threshold, the difference in the working state between the first burner and the second burner exceeds the allowable range, and the working state of the first burner and the second burner needs to be adjusted. In this embodiment, when the load deviation is greater than or equal to the deviation threshold, the first burner and the second burner are controlled to output at the target average value, that is, output at the average of the first load and the second load.

[0084] In some embodiments of this application, based on the foregoing scheme, the method further includes:

[0085] If the load deviation is less than a preset deviation threshold, then the first burner and the second burner are controlled to output at the standard value.

[0086] It is understood that the standard value refers to a pre-set theoretical value. In a pulse-type heating furnace, when the burner load reaches the preset value, the pulse is shut off. When the burner load is lower than the preset value, for example, lower than 8%, it means that the burner can reach the preset temperature with a very small amount of gas, and the pulse can be shut off. When the burner load is greater than 92%, it means that the burner needs a large amount of gas to reach the preset temperature, so continuous combustion is required. When the burner load is between 8% and 92%, the burner pulse can be intermittently controlled to achieve heat preservation before rolling.

[0087] In some embodiments of this application, based on the foregoing scheme, the heating furnace is provided with multiple heating sections on opposite sides, each heating section including multiple first burners or multiple second burners. Before obtaining the first load of the first burner, the method further includes:

[0088] For each heating section, the target pressure of each first burner or each second burner is adjusted to be consistent.

[0089] Understandably, each burner is equipped with a control valve. Before the burner enters the working state, the valve opening of each control valve is adjusted, and the pressure is measured by a pressure gauge installed on the burner tube. The valve opening is further adjusted according to the pressure to ensure that the pressure of each burner is the same, that is, the air and gas pressures are the same, the heat supply is the same, and the flames sprayed by the burners are of equal length, thus avoiding the flame of one burner being too long and the heating being uneven.

[0090] In some embodiments of this application, based on the aforementioned scheme, the first burner and the second burner are respectively provided with swirl vanes, and the swirl vanes have a preset angle with the corresponding burners.

[0091] Understandably, the swirl vane is located at the outlet of the burner and is made of stainless steel and is resistant to high temperatures. By setting a preset angle between the swirl vane and the burner, such as 42-47 degrees, the flame of the burner is guided by the swirl vane to rotate in all directions when it is ejected, reducing the flame impulse and length. This can prevent the flame from extending too far from one side to the other side and causing overheating.

[0092] Based on the above disclosure, this application embodiment obtains the first load of the first burner and the second load of the second burner, and then obtains the load deviation. If the load deviation is greater than or equal to a preset deviation threshold, the first burner and the second burner are controlled to output at the target average value, thereby controlling the temperature difference between the two sides of the heating furnace within a preset range, reducing the low temperature points generated by heating the slab, eliminating overheating of the slab, improving the temperature uniformity in the length direction of the slab, reducing the burn-off rate of the slab, and thus improving the quality of the steel coil.
