preface

In today’s world  Industry 4.0Under the promotion of the new era, not only has it ushered in a new era  Industrial InternetThe development of science and technology has also opened a new era  5G  The new dimension of the times. With the improvement of bandwidth and the rapid development of network information, energy management and real-time warning also play an important role in the industrial Internet. Blast furnace as a very important part of the iron and steel industry, its data monitoring and early warning has a very important value and significance.

Next, we will introduce how to use  Hightopo(hereinafter referred to asHT ) The technology provided has passed2/3DThe three-dimensional thermal map monitoring system of blast furnace body is built.

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 televisionBig data EraThe second episode is broadcast, which reports the outstanding contribution of the industrial Internet platform ironmaking big data to realize the digital transformation of blast furnace. 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 been 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 level iron making big data platform and industry level 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, top charging equipment, furnace body system, coarse gas system, tuyere platform and tapping yard system, slag treatment system, hot blast furnace system, coal powder preparation and injection system, auxiliary facilities 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, furnace system as the heart of the whole blast furnace ironmaking system, its service life determines the service life of the whole blast furnace system, all the auxiliary systems are for the furnace system service, important chemical reactions are also completed in the furnace system.

Specific functions and Implementation

The temperature monitoring of blast furnace body is very important. For example, if the hearth is overheated locally, the furnace body may burn through. Once the furnace body burns through, the equipment and facilities within a radius of 50 meters will disappear, causing huge economic losses and even casualties.

The three-dimensional thermal map of the system is dynamically displayed by reading the real-time data from the back-end thermal sensor, which provides the thermal range adjustment function. The thermal performance under different peak values can be adjusted according to the needs. For example, we regard 1000 ℃ as the warning value, and the thermal map will be red when it reaches the value somewhere in the furnace.

This function is usedHTIn componentsliderAccording to the value of the slider, the range of the thermal map generated by each sensor can be automatically adjusted, and the larger range of thermal maps will be aggregated together.

The blast furnace body is mainly divided into: top cover, throat, body, waist, bosh, hearth, bottom and base. It can be used after simple processing through the radius and elevation information of the corresponding position introduced by usersHTThe built-in modeling component can automatically generate the whole furnace body.

The furnace body is generated in this way, which saves the energy consumption3DIn the process of designer modeling, the furnace body of any size and height can be generated in a data-driven way.

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, thermal sensor deployment and operation state, inner wall crack, slag corrosion of bosh, hot metal corrosion of bottom and other information.

The system providesCutting functionandEndoscopic functionThe cutting function can directly view the thermal distribution inside the furnace body. In the observation mode of top view, the accurate position of overheating can be located by referring to the disc scale at the bottom.

Thermal sensors can be used to detect the temperature of blast furnace. The temperature of hot metal can be collected and calculated to reflect the heat distribution of each part of blast furnace. 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 this system is different from the 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 thermodynamic diagram. It can cooperate with the three-dimensional data panel to display the status of equipment and facilities, and it can also be used in the3DFor rendering outside the scene, click on the corresponding device2DThe status of the device is presented in the page.

You can trigger camera endoscopy by distributing events on the selected primitives, or you can do global monitoring on the 3D scene
