  With the continuous development of science and technology in China, the quality of people's daily life is becoming higher and higher. At the same time, all kinds of energy resources are being produced frequently, and the production technology and production mode of iron and steel have been concerned by the majority of enterprises. In the process of iron and steel reproduction, the operation technical management personnel should implement it according to the actual development requirements and specific conditions. Reasonable and scientific process means can effectively control the end point of converter steelmaking and add new management technologies and measures. More effectively improve the quality of steel products, but also increase the efficiency of steel production. In this paper, the end-point control technology of converter steelmaking is analyzed and discussed in detail, and some shortcomings and improvements are found out.

  In the process of iron and steel making, transfer furnace steelmaking has become a focus of development, and has also been concerned and managed by steelmaking enterprises. Nowadays, with the continuous development of China's economy and society, the transferred steelmaking technology has also been widely used and promoted. In the process of application, there are new development technologies and development models. However, there are also a series of inevitable problems in the terminal control technology in the later operation. In order to better improve the smelting quality and efficiency of iron and steel, the operation technology management personnel are constantly optimizing and improving the converter steelmaking control technology. At the same time, it not only increases the use safety of rotating shaft steelmaking, but also develops and researches the practicality and stability of steelmaking.

  1、 Common end point control technology for converter steelmaking

  (1) Intelligent control technology

  In the current industrial design process in China, there are many problems about the end-point control technology of converter steelmaking. Among them, the intelligent control management of steelmaking is also the most common. This smelting method judges its operation and management process manually, and also processes and analyzes the data and information involved in the smelting furnace in detail, so as to increase the accuracy of the data and information. Intelligent control and management can not only improve the final quality of converter steelmaking, but also improve the efficiency of converter steelmaking. In the process of production and application, high carbon steel is widely used because of its own advantages and characteristics different from other energy resources. The operation technical managers are applying intelligent control and management technology to converter steelmaking.

  (2) Static control technology

  For the static control of the end point of converter steelmaking, it is also necessary to select different new technical methods to praise and select the steelmaking types according to the raw material and equipment system of steelmaking. At the same time, molten iron and ferroalloy are added into the dimension to calculate the oxygen supply and data information of the steelmaking system. Then the characteristics of raw materials and the quality of materials are used to refine the method. At the same time, the operator and technician can reasonably and scientifically control the carbon content and temperature in the end steel through the manual inspection mode. It can not only improve the quality of steelmaking, but also speed up the efficiency of steelmaking, so that the development mode of short time and high efficiency frequently appears in the end point control technology.

  (3) Dynamic control technology

  The end-point control of converter steelmaking also includes dynamic control. When the end-point of steelmaking is almost reached, the molten pool should be inserted into the abdominal cavity in time, so that the temperature in the molten pool can be detected and adjusted in time, and more accurate values can be obtained. The operation technical management personnel can ensure the stability of the static model calculation results according to the detected data parameters. At the same time, in order to better realize the converter smelting treatment, the operation technical management personnel add the value of raw materials when ensuring the oxygen supply at the blowing end point. At the same time, it will also analyze the influence of the mechanical equipment system on the iron furnace decoration control, analyze the carbon mass fraction in the raw materials in detail, and measure and manage the carbon mass fraction through the technical method of crystallization carbon determination, so as to make the data information results more accurate. In steelmaking, if the carbon mass fraction is high, the measurement accuracy will be reduced. This operation is analyzed and discussed by technicians. The abdominal cavity dynamic key control technology is added to the production and application of low carbon steel.

  There are still some stages for the dynamic end-point control technology. For example, the detection and management of furnace gas composition in the later stage is to better determine the carbon decarburization efficiency of steel molten pool, so as to judge the composition of cylinder water and its reasonable and scientific temperature, and to better complete the transition to the dynamic end-point control of steelmaking. This furnace gas analysis and control technology can better realize the effective control of carbon resin content in molten steel, and can also effectively adjust the temperature. Operation control management personnel can accurately provide molten steel, different changes at different temperatures and carbon content. If the quality fraction of molten steel at the end point of iron furnace steelmaking is relatively low, the operation technical management personnel need to measure more accurate management systems and values to ensure the stability and effectiveness of steelmaking quality values.

  (4) Optical image control technology

  In the flow rate experiment, the operating technicians added some simple technical processing to the light intensity data in order to formulate more accurate values. The complex reaction in the steelmaking furnace will destroy the steelmaking process. Since there are many rone interference factors, these interference factors will have different effects on steelmaking, but there is a common feature that will make the light intensity change dramatically. When operating technicians extract and manage the light intensity information, in practical application, technicians judge the data information base according to the image characteristics of the furnace mouth. However, these images will change with the external temperature and the overall situation, and the flame will change.

  Therefore, he said that the control and processing of optical images by technical managers need professional technical level. It is necessary to use simple and fast processing technology to extract continuous images. For these cases, the judgment method given manually is to explore the change of the end flame. Therefore, the operation technical management personnel adopted the SV change mode to calculate the value of yellow pixel data. The results of these values are used to judge the overall changes of the image. SV transform is the most commonly used mode in flame image control technology. The processing speed of flame image can be improved, which ensures the quality and speed of steelmaking.

  2、 Development trend

  (1) Reduced demand for technical and management personnel

  Nowadays, with the rapid development of the national economy, people's economic income has become higher and higher, and there are various requirements for engineering projects. Most of the construction enterprises are contracted by enterprises. In general, there are many contracting enterprises, and the forms of construction projects are very different. In order to be the same as the principle of steel-making, it is necessary to constantly expand the building scale and management system, We should also formulate a reasonable construction scheme to comply with the construction project. Some construction enterprises will adopt the form of documents in the management and operation of the contract system, while others will adopt the form of electronic information. The system schemes between them are very different, which will lead to poor communication between them, affect the progress and quality of construction, and have potential safety hazards. According to these, we should take precautions in advance, do a good job of risk assessment in advance, strengthen the supervision and investigation of technical management personnel, and instill professional knowledge into the operation and technical personnel.

  (2) Intelligent control technology will become the mainstream

  China's domestic economic development is accelerating, the residents' requirements for quality of life have become diverse, and the steel-making industry has also stood firm in today's social market. However, the steel-making risks are also increasing. If the safety technical measures are not effectively controlled, the overall construction system will be affected. At present, the internal management of steel-making construction lacks the correct supervision system of managers, and the managers do not pay attention to the quality technology contained in the construction steel-making, which will lead to various problems in the operation of the terminal control system project.

  In addition, the final supervision of the steel-making project by the supervision department is not in place, which will cause serious damage to the fundamental problem of control, affect the completion period of the entire technical project, and affect the construction quality. There are many institutions for steel-making project construction, and the materials used in the project construction are also extensive. The surrounding institutions and operation technology management personnel are using computer network information technology to increase the management and control of iron furnace steelmaking. In the actual development and application process, changing the flow rigid mode requires new innovative development technical means, as well as operation technology management personnel with strong professional knowledge and comprehensive ability. All walks of life have played a huge role in engineering steelmaking, and there have been due functional norms in many government management.

  In addition, relevant departments in different industries will formulate reasonable solutions and measures according to scientific methods, in order to further divide the government functions of our country scientifically. In the government management of engineering construction, there are also different management responsibilities in different areas. All these require the government to establish a scientific management system based on the actual situation

  (3) Improved automation

  In the process of steel-making project construction, the enterprise and the construction unit did not follow the national construction standards and technical standards, nor did they have a complete supervision and management system. In addition, in the actual work, the staff did not connect the corresponding technologies, and the construction management system within the enterprise was not obvious.

  Moreover, as the construction industry is becoming larger and larger and the construction technology is becoming higher and higher, there will be a series of safety technical problems. If the construction management personnel do not make a complete system plan during the construction operation, and the staff do not complete the docking work with their own expertise in the actual work, the internal responsibility division of the construction enterprise is not clear. There will also be many projects without professional guidance, which will seriously affect the progress and quality of construction. Therefore, in order to avoid these situations, the steel-making management department should improve the operation mode of mechanical equipment automation.

  If the steel-making enterprise fails to carry out construction within the specified time, it will not be able to meet the construction requirements without training professional technicians. If the automation technology level is not applied according to the actual requirements, the final quality and efficiency of steel-making will be affected. At the same time, in the steel-making construction site, the technical level of the workers themselves. If they fail to meet the qualified requirements, the construction effect will be affected.

  3、 Concluding remarks

  According to what we have learned above, during the actual development and treatment of steelmaking, some metal objects will melt in the construction environment with very high temperature. Therefore, the operation and technical personnel need to further innovate and improve the heat treatment mode applied in steelmaking. In order to better ensure the accuracy and stability of data information of mechanical equipment parts, it is necessary to make clear the specific internal conditions of converter steelmaking and apply reasonable and scientific processing technology to improve the performance of parts.

  The raw materials of steel-making mechanical equipment shall be carefully supervised and selected to ensure that the basic size of raw materials will not be affected by other factors. At the same time, mechanical equipment with strong hardness shall be selected to control the degree of deformation and effectively improve the overall flexibility and performance of materials.
