The partition sintering end point judging method based on thermal imaging can be applied to the technical field of sintering production. In the current sintering production process, the sintering end point position is generally obtained by measuring the exhaust gas temperature of a wind box, so as to judge the sintering state. However, the method of determining the sintering state from the position of the sintering end point is not accurate enough based on the current method of obtaining the position of the sintering end point.
In order to solve the technical problem, the embodiment of the present application provides a method for determining a zoned sintering endpoint based on thermal imaging. In some embodiments, the thermal imaging-based zoned sintering endpoint determination method may be performed by an electronic device.
Fig. 1 shows a flowchart of a method for determining an endpoint of zoned sintering based on thermal imaging in an embodiment of the present application. Referring to fig. 1, the method for determining the endpoint of the zoned sintering based on thermal imaging in the present embodiment includes:
step S101: and acquiring temperature field data of the material layer section.
Step S102: and carrying out regional division on the material layer section, and obtaining regional material layer section temperature field data according to the material layer section temperature field data.
Step S103: and judging the sintering end point state of the section of the material layer in the region according to the temperature field data of the section of the material layer in the region and the characteristic value model of the sintering end point position, wherein the sintering end point state comprises a normal state, an over-burning state or an under-burning state.
Through adopting above technical scheme, through directly obtaining bed of material section temperature field data, carry out regional division to the bed of material section again, according to bed of material section temperature field data, obtain zone bed of material section temperature field data, according to zone bed of material section temperature field data and sintering terminal point position eigenvalue model, judge the sectional sintering terminal point state of zone bed of material, can obtain the sintering terminal point state that the sintering terminal point in each region of bed of material section corresponds, can improve and judge the not accurate problem of sintering state inadequately according to the method that obtains sintering terminal point position at present, reach more meticulous acquisition sintering terminal point position, with the effect of the precision of improvement judgement sintering state.
In step S101, the temperature field data of the material layer cross section at the moment of dropping the material layer of the trolley is obtained by analyzing the video content of the thermal imaging video at the tail of the sintering machine. The material layer section temperature field data comprises the positions and temperature values of all points (temperature points) of the material layer section.
In the embodiment of the application, the thermal imaging video of the tail part of the sintering machine is obtained from a thermal imaging device installed at the tail part of the sintering machine. The thermal imaging device comprises a handheld thermal infrared imager, a night vision thermal infrared imager and an industrial high temperature thermal infrared imager. When the thermal imaging video of the tail part of the sintering machine is obtained, a water cooling protection device can be arranged around the thermal imaging device so as to reduce the influence of high temperature on the instrument.
Optionally, the thermal imaging device is an industrial high temperature thermal infrared imager. Based on the adaptability of the industrial high-temperature thermal infrared imager to high temperature, the industrial high-temperature thermal infrared imager is more suitable for the sintering production process on an industrial basis.
In the embodiment of the application, the industrial high-temperature thermal infrared imager converts an electronic video signal measured by an infrared detector into an infrared thermal image through a two-dimensional plane imaging infrared system, displays the infrared thermal image by a display for manual real-time checking, can intelligently identify indexes such as temperature, thickness and uniformity of a red layer of a sintering machine tail material layer, and uploads result data to a partition sintering end point judgment device based on thermal imaging in real time.
In the embodiment of the application, the installation position of the thermal imaging device is arranged outside the dust hood at the tail part of the sintering machine and is just opposite to the lower part of the section of a material layer at the tail part of the sintering machine. The camera position of the thermal imaging device forms an included angle of 10-15 degrees with the bottom surface of the sintering trolley so as to ensure that the camera is vertical to the section of the material layer exposed when the sintering ore of the trolley falls.
Optionally, the position of the camera of the thermal imaging device is 12 ° with the bottom surface of the sintering pallet.
In the embodiment of the present application, the number of the material layer section temperature points included in the material layer section temperature field data may be set.
Optionally, the set bed profile includes 3600 temperature points.
In step S102, the material bed cross section is divided into regions based on the number and positions of the material distribution gates. Specifically, the section of the tail of the sintering machine is extended in the horizontal direction, and partitioning is performed based on the number of the distribution gates and the positions corresponding to the distribution gates. Based on the temperature field data, the number of the distribution gates and the corresponding positions of the distribution gates, the temperature field data of the material layer section can be divided into a plurality of regional temperature field data of the material layer section. Wherein, each regional bed section corresponds to a distribution gate and the regional position of the bed section that this distribution gate corresponds.
In other words, the material layer section is divided into regions according to the number of the material distribution gates and the positions corresponding to the material distribution gates, so that the material layer section temperature field data is divided into a plurality of regional material layer section temperature field data.
In the embodiment of the application, the number of the users of the distribution gate and the corresponding position of the distribution gate can be determined according to actual conditions.
For example, there are 6 distribution gates in the sintering machine and each distribution gate is distributed at equal intervals, based on the number and position of the distribution gates, the material layer section can be equally divided into 6 regions with equal area, each region corresponds to one distribution gate, that is, the material layer section temperature field data is divided into 6 groups of material layer section temperature field data (i.e., 6 regions of material layer section temperature field data).
In step S103, based on the sintering end position characteristic value model, the sintering end state of the zone bed cross section of each zone is determined from the zone bed cross section temperature field data of each zone (that is, from the position and the temperature value of the temperature point of each zone).
In the embodiment of the present application, based on the sintering end point position characteristic value model, the smaller the calculated characteristic value of the temperature point is, the closer the combustion layer in the material layer cross section is to the bottom surface of the trolley, the closer the combustion layer is to complete sintering is.
In the embodiment of the present application, the sintering end point state includes an under-sintered state, a normal state, and an over-sintered state, which correspond to the stage of the sintering process. For example, under-fired state refers to sintering in which the sintering time is so short that the product does not reach the desired properties during sintering. The overburning state means that the sintering residence time is too long in the sintering process, so that the productivity of the sintering machine is reduced.
In some embodiments, the regional layer section temperature field data includes a position and a temperature value for each point within each regional layer section; step S103 includes: step a 1-step a 2.
Step A1: and calculating the characteristic value of the relative position of the highest temperature point on the material layer section according to the temperature field data of the material layer section in the region based on the sintering end point position characteristic value model.
Step A2: and judging the state of the sintering end point according to the characteristic value.
In the embodiment of the present application, the highest temperature point is set as the sintering end point position in the region, that is, the temperature point with the highest temperature value in the temperature points in the region is set as the sintering end point position in the region. And calculating the characteristic value of the relative position of the temperature point with the highest temperature value in each region temperature point in the material layer section according to the position and the temperature value of the material layer section temperature point in each region, and judging the sintering end point state of the material layer section of each region.
By adopting the technical scheme, based on the sintering end point position characteristic value model, the characteristic value of the relative position of the temperature point with the highest temperature value in each region temperature point in the material layer section is calculated according to the region material layer section temperature field data, and then the sintering end point state of the material layer section of each region is judged according to the characteristic value, so that the sintering end point position can be obtained more finely, and the precision effect of judging the sintering state is improved.
In some embodiments, the method for constructing the sintering end position characteristic value model includes:
and constructing the sintering end point position characteristic value model according to the number of temperature points between the highest temperature point of the material layer section and the bottom of the trolley and/or the total temperature point number of the material layer section.
In the embodiment of the present application, the sintering end position characteristic value model is represented by the following formula:
k＝(K/N)×100-10
wherein K represents a characteristic value of a sintering end point position, and K represents the number of temperature points between the highest temperature of the material layer section and the bottom of the trolley; n represents the total temperature point number of the material layer section.
By adopting the technical scheme, the sintering end point state of the material layer section of each region is calculated based on the characteristic value model of the sintering end point position, so that the sintering end point position can be obtained more finely, and the precision effect of judging the sintering state is improved.
In some embodiments, step a2 includes: step a 1-step a 3.
Step a 1: and judging whether the characteristic value is larger than a first preset characteristic value or not, if so, determining that the sintering end point state is an under-sintered state.
Step a 2: if the characteristic value is not larger than a first preset characteristic value, judging whether the characteristic value is smaller than a second preset characteristic value, and if so, judging that the sintering end point state is an over-sintering state.
Step a 3: and if the characteristic value is not less than a second preset characteristic value, the sintering end point state is a normal state.
Wherein the first preset characteristic value is greater than the second preset characteristic value.
In the embodiment of the present application, the sintering end point state corresponding to each region is determined according to the feature value of the sintering end point position of each region. The first preset characteristic value and the second preset characteristic value can be set according to the empirical value.
For example, the first preset feature value is set to 30, and the second preset feature value is set to 10. If the characteristic value of the sintering end point position of the region is more than 30, the sintering end point state of the region is an under-sintered state; if the characteristic value of the sintering end point position of the region is less than 10, the sintering end point state of the region is an over-sintering state; the characteristic value of the sintering end position of the region is between 10 and 30, and the sintering end state of the region is a normal state.
For another example, if the sintering end point position characteristic values of 6 regions (i.e., region 1, region 2, region 3, region 4, region 5, and region 6) calculated from the 6 region material layer cross-sectional temperature field data based on the sintering end point position characteristic value model are 8.7, 18.6, 20.3, 19.5, 18.5, and 10.5, respectively, the sintering end point state of region 1 is an over-fired state, the sintering end point state of region 3 is an under-fired state, and the sintering end point states of the other regions are normal states.
By adopting the technical scheme, the sintering end point state of each area is cut off based on the characteristic value, the first preset characteristic value and the second preset characteristic value, so that a more refined sintering end point position can be obtained, and the precision effect of judging the sintering state is improved.
In conclusion, the method for judging the zoned sintering end point based on thermal imaging can achieve the purpose of judging the zoned sintering end point by acquiring the temperature values and positions of all points of the material layer section at the tail part of the sintering machine, partitioning the material layer section according to the corresponding relation of the material distribution gates and calculating the sintering end point state of each partition by utilizing the temperature distribution characteristics of the material layer section of each partition. Meanwhile, after the sintering end point state is judged in a partition mode. The material distribution can be adjusted in different areas, so that the sintering end point is more reasonable.
