On July 2, China’s first big data industry documentary jointly produced by the Ministry of industry and information technology and China Central Radio and Television CorporationBig data ageEpisode 2 is broadcast, reporting the outstanding contribution of iron making big data on the industrial Internet platform to the digital transformation of blast furnace. The digital transformation of traditional industrial enterprises is an important issue in industrial transformation and upgrading.
Although the output of China’s iron and steel industry has ranked first in the world for many years, it is still in the development stage from large to strong. China’s iron and steel industry has been committed to the R & D and promotion of iron making sensors, Internet of things, industrial model software, expert system, enterprise iron making big data platform and industrial Internet platform. At present, one belt, one road and one other national steel enterprise, has been completed and the 260 big blast furnaces in China have been digitized and intelligentized. The large scale data platform has been applied in the “one belt and one way” national iron and steel enterprises in Russia, Vietnam, Iran and Indonesia. The annual efficiency of the single blast furnace has been increased by over 24 million yuan / year, and the deep integration of big data, mechanism model, artificial intelligence and traditional manufacturing industry has been realized. It is a typical application of intelligence + industry.
The whole blast furnace ironmaking process mainly involves the following systems: raw material system, charging system, furnace top charging equipment, furnace body system, crude gas system, tuyere platform and tapping yard system, slag treatment system, hot blast furnace system, pulverized coal preparation and injection system and auxiliary facility system. The complete process demonstration can refer to another excellent blast furnace system article 《Visualization system of blast furnace ironmaking plant based on HTML5 webgl 》
This paper mainly describes Furnace body systemThe function and effect of this part. As the heart of the whole blast furnace ironmaking system, the service life of the furnace body system determines the service life of the whole blast furnace system. All auxiliary systems serve the furnace body system, and important chemical reactions are completed in the furnace body system.
Specific functions and Implementation
The temperature monitoring of the blast furnace body is very important. For example, if the hearth is overheated locally, the furnace body may be burned through. Once burned through, the equipment and facilities within a radius of 50m will disappear, causing huge economic losses and even casualties.
The three-dimensional thermal diagram of the system is dynamically presented by reading the real-time incoming thermal sensor data from the back end, providing the thermal range adjustment function, and the thermal performance at different peaks can be adjusted as required. For example, we regard 1000 ° C as an early warning value, and the thermal diagram appears red when it reaches this value somewhere in the furnace body.
This function is usedHTIn componentslider, the thermal map range generated by each sensor can be automatically adjusted according to the value of the slider, and the thermal maps with a large range will be aggregated.
The blast furnace body is mainly divided into: furnace top cover, furnace throat, furnace body, furnace waist, bosh, hearth, furnace bottom and furnace base. The radius and elevation information of the corresponding position transmitted by the user can be used after simple processingHTThe built-in modeling component can automatically generate the whole furnace body.
The furnace body is generated in this way, which saves the cost3DIn the process of modeling, designers can generate furnace bodies of any size and height in a data-driven way.
The quality of the furnace shape is related to the output and service life of the blast furnace. The system also provides the function of dynamically adjusting the size of each key position of the blast furnace body, which can be used for blast furnace design and planning, in order to observe the output efficiency and load capacity of the blast furnace under different blast furnace sizes and optimize the blast furnace shape.
The internal state of blast furnace is often the focus of attention, such as lining state, deployment and operation state of thermal sensors, inner wall cracks, bosh slag corrosion, molten iron corrosion at the bottom and so on.
The system providesSectioning functionandEndoscopic function, the sectioning function can intuitively view the thermal distribution inside the furnace body. In the observation mode of top view, you can refer to the disc scale at the bottom to locate the accurate orientation of overheating.
The temperature of blast furnace can be detected by thermal sensor, which can reflect the heat distribution of each part of blast furnace body by collecting the temperature of molten iron and calculating and analyzing it. When the system is used for designing, simultaneous interpreting the relationship between the distribution of different sensors and the thermal distribution range can be directly observed by adjusting the position of the sensor, so as to achieve the goal of reasonably setting the location of the sensor.
The endoscope function of the system is different from sectioning. The endoscope is mainly used to observe the positioning and detection data of various equipment inside the furnace. At this time, there is no need to present the thermal diagram. It can cooperate with the three-dimensional data panel to display the status of equipment and facilities, or3DFor rendering outside the scene, click the corresponding device to2DThe status of the device is presented in the page.
You can trigger camera endoscopy by sending events on the selected primitive, or you can do global monitoring on the 3D scene
digitizationand IntellectualizationControl is Industrial InternetIn the era of rapid information transmission, the combination of data visualization and intelligent control will deduce many amazing effects. Under the supervision of real-time data, early warning information is also very important. While ensuring the orderly progress of production, we should also pay attention to production safety, production efficiency, resource utilization, environmental problems and so on.
