Preface
my country's steel industry has been committed to the development and promotion of overall solutions for ironmaking sensors, Internet of Things, industrial model software, expert systems, enterprise-level ironmaking big data platforms, and industry-level industrial Internet platforms. At present, the digitalization and intelligentization of 260 domestic blast furnaces have been completed, and the ironmaking big data platform has been promoted in the steel enterprises of Russia, Vietnam, Iran, Indonesia and other "Belt and Road" countries. The annual cost reduction and efficiency increase of a single blast furnace exceeds 2400. RMB 10,000 per year, which realizes the deep integration of big data, mechanism models, artificial intelligence and traditional manufacturing, and is a typical application of intelligence + industry.
In today's industry 4.0 under the impetus of a new era, not only ushered in the industry of Internet development, but also opened a 5G new dimension of time. With the increase in bandwidth and rapid development of network information, energy management and real-time warning also play a pivotal role in the industrial Internet. As a very important part of the iron and steel industry, the blast furnace has extremely important value and significance for its data monitoring and early warning.
Below we will introduce the 3D heat map monitoring system of the blast furnace body built through 2/3D fusion using the technology provided by Hightopo (hereinafter referred to as HT ) .
Interface introduction and effect preview
The basic information of the blast furnace, thermal sensor information, and blast furnace detection information are presented on the 2D panel; the real geometric structure of the blast furnace is presented in the 3D visualization scene, and the temperature information of each key position of the blast furnace is presented using a three-dimensional heat map. The bottom position pointer locates the blast furnace The orientation and sensor position, and the height signs on both sides show the height information of the key positions of the furnace.

In the realization of the visualization system, the 3D scene adopts the HT lightweight HTML5/WebGL modeling solution, which achieves fast modeling, lightweight runtime and even mobile terminal browsers can achieve good effects of 3D visualization operation and maintenance; and in the corresponding On the 2D drawings, the unique vector is used, which is not distorted under various ratios, and the layout mechanism solves the display problem under different screen ratios.
Specific function and realization
The entire blast furnace ironmaking process mainly involves the following systems: raw material system, feeding system, furnace top charging equipment, furnace body system, crude gas system, tuyere platform and tapping yard system, slag processing system, hot blast stove system, pulverized coal Preparation and injection system, auxiliary facility system. The furnace system is the heart of the entire blast furnace ironmaking system. Its service life determines the life of the entire blast furnace system. All subsidiary systems serve the furnace system, and important chemical reactions are also completed in the furnace system. .
The temperature monitoring of the blast furnace body is very important. For example, if the hearth is partially overheated, the furnace body may burn through accidents. Once burned through, the equipment and facilities within a radius of 50 meters will disappear and will face huge economic losses and even casualties. .
At this time, using our system, the intuitive three-dimensional heat map can be dynamically presented by reading the real-time incoming thermal sensor data from the backend, providing the thermal range adjustment function, and adjusting the thermal performance under different peaks according to needs, such as our Regarding 1000 degrees Celsius as an early warning value, the heat map appears red when the value is reached somewhere in the furnace.
The blast furnace body is mainly divided into: furnace top cover, furnace throat, furnace body, furnace waist, furnace stomach, hearth, furnace bottom, furnace base, through the user's input of the radius and elevation information of the corresponding position, after simple processing The entire furnace body can be automatically generated using the built-in modeling components of HT .
The furnace body is generated in this way, eliminating the process of 3D designer modeling, and the furnace body of any size and height can be generated in a data-driven manner.
The quality of the furnace type is related to the output and life of the blast furnace. The system also provides the function of dynamically adjusting the dimensions of each key position of the blast furnace body, which can be used for blast furnace design and planning, in order to achieve the observation of blast furnace output efficiency under different blast furnace sizes. Load capacity, optimize blast furnace shape.
The internal state of the blast furnace is often also the focus of attention, such as: lining state, thermal sensor deployment and operation state, internal wall cracks, furnace slag corrosion, furnace bottom molten iron corrosion and other information.
This system also provides sectioning function and endoscopic function . The sectioning function can intuitively view the heat distribution inside the furnace body. In the observation mode of the top view, you can refer to the disc scale at the bottom to locate the accurate location of the overheated area. .
A thermal sensor can be used to detect the temperature of a blast furnace. By collecting the temperature of the molten iron and calculating and analyzing, the heat distribution of each part of the blast furnace body can be reflected. When the system is used for design, the relationship between the distribution of different sensors and the thermal distribution range can be observed intuitively by adjusting the position of the sensor, so as to achieve the purpose of setting the sensor distribution position reasonably.
The endoscopy function of this system is different from sectioning. The endoscopy is mainly used to observe the positioning and detection data of various equipment inside the furnace. At this time, there is no need to use a heat map to present it, and it can be used with a three-dimensional data panel to display the status of equipment and facilities. , You can also do presentation outside the 3D scene, click on the corresponding device to display the status of the device in the 2D page.
The camera can be triggered by dispatching events on the selected primitives, or global monitoring can be done on the 3D scene.
to sum up
Under real-time data supervision, early warning information is also very important. While ensuring the orderly progress of production, it accelerates production efficiency and solves resource utilization problems, environmental problems, and so on. Digitization and intelligent management and control are the development trend of the industrial Internet , which has liberated manpower and labor to a large extent. In the era of rapid information transmission, the combination of data visualization and intelligent management and control will produce many surprising effect collisions.
