According to "Technology Daily" reported on May 11, 2006: Organizational performance prediction technology is a hotspot and focus of international metallurgical research and development in recent years, and is one of the major cutting-edge technologies and research hotspots in the field of metallurgy. China is currently in a period of rapid economic development, and the demand for steel materials, which are urgently needed in the fields of construction, manufacturing, machinery, transportation, etc., is increasing. In 2005, China's crude steel output reached 349 million tons, and steel output reached 371 million tons, including 141 million tons of sheet products. Plate and strip are among the high-end products in the steel product structure. In recent years, the internationally renowned steel enterprises are pursuing scale operation and pursuing advanced product structure, focusing on the development of high-tech and high value-added sheet and strip products. And control the market and technology of key sheet and strip varieties. At the same time, major steel companies in the world's major steel producing countries attach great importance to the development and application of automated control, flexible production and performance-oriented process control technologies in steel production. In recent years, with the development of physical metallurgy theory and computer numerical computing technology, process simulation technology has gradually extended from product size and surface quality control to tissue evolution simulation and product performance prediction and control in the production process. Scholars from all over the world have developed a prediction and control system for the hot-rolled microstructure of steel. At present, the hot-rolled microstructure performance prediction technology is mainly flat steel, which can be extended to long profile production and pipe production. China started late in the development of hot rolling microstructure performance simulation system software, limited to the lack of systematic and capital investment, and the research on mature applicable integrated simulation system software is relatively late.

Development and application of structural performance prediction technology in continuous casting and rolling process and related technology The basic research project aims to control the casting, controlled rolling and controlled cooling conditions from high-efficiency continuous casting of cast slab to hot rolling forming. Underlying component-process-organization-performance integration model and software system, develop simulation software packages and related application technologies for solidification, heating, deformation, recrystallization, phase transformation, quantitative relationship between organization and performance, and guide engineering and technical personnel to master the whole system. Physical metallurgical changes in the process, optimizing alloy design and production of controllable process parameters, reducing performance fluctuations and sampling times, shortening delivery cycles, and improving control levels. The research is mainly aimed at continuous casting and hot rolling of strip steel to predict the distribution of the length and thickness direction of the strip and the general mechanical properties under different conditions and continuous casting and rolling conditions, so as to optimize the process parameters and alloy design. Guide production and bring economic benefits to the company.
Organizational performance prediction technology can guide the development of new processes and new varieties and shorten the product development cycle. The application of tissue performance prediction technology can avoid some trial tests of the cooking type in the past when developing new varieties, and can reduce the test by more than 1/2. If the price per ton of hot-rolled sheet is 3,000 yuan / ton, the development of a long-term variety can directly save about 15 million yuan. The varieties of hot-rolled products in China are at the peak of development. The diversity of market demand requires many varieties of hot-rolled mills every year. It can be seen that the use of tissue performance prediction technology has a huge role in saving funds. In optimizing the production process, the quality and quality stability of the product can be improved, and the production cost is reduced in the long run, and the benefit is difficult to calculate.
After the application of the tissue performance prediction system in China's hot rolling production line, the number of samples of the manufactured products can be reduced. However, due to the relative backwardness of China's technical standards, it is necessary to first modify the ex-factory standards of metallurgical products.
With the continuous development of China's national economy, the specifications and performance of products must be updated and replaced, and many production lines must be transformed. If the technical equipment is fully imported from abroad, it will cost the country a large amount of construction investment. The application of this technology can greatly save market investment and provide technical support for the transformation and design of production equipment.
The application of organizational performance prediction technology can optimize the existing production process and improve product performance without improving the grade. The steel structure performance forecasting system provides a digital platform for steel producers. With this platform, users can optimize production and improve product quality while minimizing production costs.

The microstructure performance prediction system for steel hot rolling process is a necessary means for steel enterprises to realize digital quantitative and controllable production. Its technology application and promotion prospects are very good, and direct and indirect economic benefits are huge. At present, major steel companies in the world's major steel producing countries have basically adopted or are developing numerical simulation and simulation technology systems. China is at the beginning and progress stage in this crucial area that determines the future competitiveness of steel companies. So far, there are nearly 20 traditional continuous casting and rolling production lines in China, and nearly 15 CSP production lines have been put into production and are being proposed. These steel companies will sooner or later be inevitable users of the steel structure performance forecasting system. In addition, since the technology can be easily transplanted to similar production lines, such as hot-rolled plate production line, hot-rolled bar wire production line, hot-rolled steel pipe production line, etc., these are potential users of the steel structure performance prediction system.
