(CCTV Finance "Economic Information Network") For a long time, the melting component detection of the metallurgical industry has relied on manual sampling, which is not only dangerous, but also causes great waste. Today, I came to know a high-ranking man, who was young, but he refined the "golden eye of fire" of smelting and sampling, and solved the century-old problem of the industry.
Uncover the mysteries of composition with lasers and solve the dilemma of sampling in a century-old furnace
As the laser sound fell, Pan Congyuan knew the composition and content without touching the measured object.
Pan Congyuan, technical director of Hefei Jinxing Intelligent Control Technology Co., Ltd.: Copper, sulfur, iron, silicon, etc. can all be detected, which is suitable for the detection of all elements of the periodic table.
The product that realizes this function is called laser composition analyzer, which is developed by the team led by Pan Congyuan. It is the world's first commercial device to realize the online detection of high-temperature melt components.
For more than a hundred years, samplers have been high-risk in smelters around the world, relying on manual means to take samples from melts at more than 1,000 degrees Celsius, taking two to six hours at a time. This is not only dangerous, but also often inaccurate, resulting in high scrap rates and serious waste.
Pan began thinking about the possibility of using lasers to detect melts online more than a decade ago. In recent years, he has spent most of his time collecting first-hand data in smelters with high temperatures, high dust, and harmful gases.
Pan Congyuan, technical director of Hefei Jinxing Intelligent Control Technology Co., Ltd.: We have no way to simulate a melt with a high temperature of more than 1,000 degrees Celsius in the laboratory, and we can only rely on the continuous accumulation of databases during long-term use on site.
Back in the laboratory, Pan Congyuan is even more famous for his "golden eye of fire".
Wang Qiqi, engineer of the technical department of Hefei Jinxing Intelligent Control Technology Co., Ltd.: We tested for about a week, but we couldn't find the problem, and then Dr. Pan came over, took a brief look at the spot, and quickly found the problem.
The effort pays off, and with the product on the ground, smelters can now know the test results without taking samples.
Pan Congyuan, technical director of Hefei Jinxing Intelligent Control Technology Co., Ltd.: Now our equipment does not need to be manually sampled, and people can do more valuable things.
Pan Congyuan's technological breakthrough has filled the gap in the industry, reducing the price of international related equipment from 12 million yuan to 6 million yuan, and the market share of products has reached the international leading level.
This issue specializes in special new and advanced people: smelting and sampling, refining is not afraid of difficulties "fire eye golden eye"; Laser flashing to achieve scientific and technological innovation "see flowers in the fog"; The thousand-degree furnace is hot but the "heart of a strong country" in the manufacturing industry.
