On the morning of October 10, the "Double Bottom Blowing" continuous copper smelting technology industrialization development and application of scientific and technological achievements evaluation meeting was held in Jiyuan City, Henan Province. The meeting evaluated the "double bottom blowing" continuous copper smelting technology jointly developed by China Enfi Engineering Technology Co., Ltd. and Henan Yuguang Gold Lead Co., Ltd. and the first industrial application in Yuguang. The evaluation committee agreed that the technology was highly innovative and that the overall technology had reached the international leading level.
At the evaluation meeting, Qiu Dingfan, the leader of the evaluation committee and an academician of the Chinese Academy of Engineering, said excitedly: "You have realized the dream of a generation. Continuous copper smelting is a long-term wish of our non-ferrous metallurgical science and technology personnel. This result is a great initiative of our country. In the past, the biggest problem of copper smelting was environmental pollution, and the biggest problem of environmental pollution was low-altitude pollution. The biggest advantage of continuous copper smelting is to solve the low-altitude pollution problem inside the workshop, which is difficult to do. In addition, the technical indicators are very advanced, the equipment is very good, and the degree of automation is high, so we evaluate this technology as the highest level of international leading level. There is still room for development in this project. I hope this project will start from Yuguang. The world is flourishing. "
Yang Guang, Chairman of Yuguang Group, gave a welcome speech at the meeting. He introduced the technological innovation of Yuguang and the application of the "double bottom blowing" continuous copper smelting technology. Yuguang insists on the combination of independent development and introduction of digestion and absorption, giving full play to the company's overall advantages, and constantly consolidating the company's technological innovation foundation. Over the years, Yuguang has formed a number of internationally leading core technologies with independent intellectual property rights through independent research and development. Yuguang also set up "One Academy and Eight Institutes" to extend the innovation platform again to ensure that future scientific and technological development plans are enhanced and the company's core competitiveness is continuously improved.
"Double bottom blowing" continuous copper smelting technology is an independent core technology formed by the cooperation between China Enfi and Yuguang. Yuguang's "double bottom blowing" continuous copper smelting technology industrialization development and application project is the first project in the world to successfully apply "double bottom blowing" continuous copper smelting technology to industrialization. In the production process, Yuguang constantly perfects the technology. This technology has the advantages of strong adaptability to raw materials, continuous smelting, low energy consumption, high metal recovery rate, good environmental protection, low investment, and high degree of automation. It has the ability to process recycled copper and copper concentrates, and solves the PS converter in the copper smelting industry. The problem of continuous smelting and low-altitude pollution has refreshed the history of copper smelting.
The evaluation committee listened to the project report and came to the site to view it. Came to Henan Yuguang Gold & Lead Co., Ltd.'s "double bottom blowing" continuous copper smelting technology industrialization development and application project project site, the evaluation committee went to the smelting furnace, blowing furnace front, slag mouth and other sites to see and understand Details of the application of technology to industrialization. After on-site inspections, experts said that the production scenes seen in Yuguang are things that they dared not think about in the past, and the achievements of the old generation of non-ferrous smelters. And this technology is China's own technology, Yuguang successfully industrialized this technology, which is China's pride.
After listening to the project report and on-site inspection, the evaluation committee evaluated the degree of technological innovation, the advanced level of technical and economic indicators, the degree of difficulty and complexity of the technology, the reproducibility and maturity of the technology, and the role of technological innovation in advancing industry scientific and technological progress and improving market competitiveness. Scores on six indicators including role, economic and social benefits.
The Evaluation Committee believes that the "double bottom blowing" continuous copper smelting technology has a high degree of innovation, which is a technological innovation with China's independent and independent intellectual property rights, and a major breakthrough. The project developed a set of “double bottom-blown” continuous copper smelting industrialization technology, built a “double bottom-blown” continuous copper smelting industrial production system, established a bottom-blown continuous copper smelting production technology system, and realized stable operation of industrial production. The unique performance of the technology. The successful development of the project solved the worldwide problem of low-altitude pollution existing in traditional PS converter blowing, and played an important leading role in the development of copper smelting technology.
"Double bottom blowing" continuous copper smelting has advanced technical and economic indicators, high technical difficulty and complexity, good technical reproducibility, high maturity, significant economic and social benefits, and significant energy saving and emission reduction effects. This technology has significantly improved China's market competitiveness in the world's copper smelting industry, led the development of technological innovation in China's copper smelting industry, and refreshed the world's copper smelting history.
