Laser induced plasma spectrometer major instrument development special start

May 05, 2021

Recently, Opto-Electronics held a launching ceremony for the “Development and Application of Laser Induced Plasma Spectroscopic Analysis Equipment” special project for the development of major national scientific instruments and equipment at the Beijing New Technology Base. At the meeting, Jiang Yanbin, deputy director of the Scientific and Technological Conditions Division of the Bureau of Finance and Economics of the Chinese Academy of Sciences, attended the meeting on behalf of the hospital authorities. A total of more than 50 representatives of the experts inside and outside the hospital, the project supervision team and the cooperative units attended the meeting.

Vice-President Fan Zhongwei participated in the project kick-off meeting and technical seminars and stated that he will aim at application goals and do his best to make the project a success. Sun Hui, the project leader, reported on the project's background, development and engineering plans, schedule, organization and management, and progress. Participating experts focused on in-depth discussions on project intellectual property protection, management measures, detailed indicators, interface relationships, and technical difficulties, and put forward many valuable opinions and suggestions.

In his last speech, Jiang Yanbin put forward three major requirements: First, to give full play to the roles of the overall group, the technical expert group, and the supervision team. The second is to stress the importance of the mission statement, in which the adjustment of funds, indicators and cycles must strictly comply with the relevant procedural requirements. The third is to strengthen the emphasis on project quality, reliability and related software. Through the overall coordination and coordination of the project, do a good job of planning in advance to provide guarantee for the smooth development of the project.

At present, the total crude steel production in China is close to half of the world's total. The output of special steel is less than 5%, and the quality needs to be improved. It is mainly due to the difficulty in controlling the composition of molten steel during the smelting process and the low yield rate. The existing component detection technology takes a long time and is an after-the-fact detection method and cannot provide a real-time reference for quality improvement. Laser induced plasma spectroscopy (LIPS technology) is a quantitative analysis technique based on the interaction of laser and material to generate emission spectrum, providing a possibility of real-time online monitoring, which can provide real-time quantitative basis for improving molten steel quality. Shortening the inspection time can also reduce costs and save energy.

Because developed countries have narrow-component control technologies, they have ensured that special steel accounts for a high proportion of total steel production. The LIPS research in the metallurgical industry in China is still in its infancy, and the research and development of related equipment is almost blank. This project aims at the characteristics of high-temperature smelting environment, and develops a real-time on-line detection device based on laser-induced plasma spectroscopy for steel components, which is not only conducive to promoting the research and application development of steel composition detection technology in China, but also helps to improve the quality of steel products in The development of the industry has important strategic significance.
