According to statistics from the Non-Ferrous Metals Industry Association, China's lead production was 4.199.4 million tons in 2010, which accounted for 44.66% of the world's total output. It ranked first in the world for 18 consecutive years; lead consumption was about 3.95 million tons, accounting for 44% of the world's total consumption. %, ranking first in the world for 10 consecutive years. Lead has a very important role in the development of the national economy.
In the 1950s, lead smelting companies represented by Yuguang were difficult to start; in the 1960s and 1970s, they marched in difficulties; in the 1980s and 1990s, they steadily developed; in the 21st century, they ushered in the heyday of development and became international lead zinc. A first-class enterprise that is highly competitive in the industry. Among them, Yuguang has developed into Asia's largest lead smelting company. Yuguang development history, is the history of Chinese lead smelting enterprises; Yuguang lead smelting technology used at different times, is the history of the development of China's lead smelting technology.
■Non-steady-state SO2 conversion technology — Breaking through the development bottleneck of the lead smelting industry 54 years ago, when Yuguang was built, it adopted the most primitive method of earth-smelting lead. From 1987 to 1991, the first-phase and second-phase expansion projects were completed successively, and the company’s lead production capacity was increased to 15,000 tons. At this time, Yuguang leadership aware of: pollution simply expand the scale of production, on the environment, companies want to get considerable development, the need for technological innovation.
On October 20, 1993, Yuguang invested 148 million yuan in the three-phase expansion project of gold, silver and lead. In 1996, the third phase of the expansion of sintering machine system, lead melting blast furnace has been ignited. In 1997, the flue gas acidification project was successfully tested. In the third phase of technological transformation project, Yuguang was the first company in the same industry in the country to apply non-steady-state oxidation* conversion technology to recycle low-concentration dioxide*, breaking the bottleneck restricting the development of lead smelting enterprises and becoming the development of domestic lead smelting industry. A milestone in history. Since then, the domestic same industry has used this technology to create a new situation for lead smelting companies to comprehensively return to production and production. The non-steady state oxidation* conversion technology won the second prize of scientific and technological progress of the Ministry of Education.
â– oxygen bottom-blowing blast furnace oxidation reduction lead smelting technology --- represent the development direction of China's lead smelting technology in early 1999, Yuguang first application of oxygen-rich bottom blowing oxidation --- blast furnace lead smelting reduction technology. In this regard, the State Economic and Trade Commission, the National Development Bank, the Nonferrous Metals Industry Bureau, the China Nonferrous Metals Industry Association, and the Henan Provincial Economic and Trade Commission all expressed strong support. In May 2002, Yuguang's first oxygen bottom furnace system was completed and put into operation. In December 2002, 7 experts led by Zhang Guo, academician of the Chinese Academy of Engineering, visited Jiyuan, and they all agreed that the project has reasonable process and assembly, reliable performance, high operating rate, and obvious environmental protection effect. The technical level has reached the leading domestic and international advanced level. Lead smelting technology reform plays a good demonstration role and represents the development direction of China's lead smelting technology.
It is understood that at present, there are 16 lead smelting plants in China that use oxygen-blown smelting technology and 15 are under construction. In 2009, the process began to move toward the world. India has chosen this technology; Australia has also shipped materials for industrialization experiments and is preparing to introduce this technology to renovate the Pili Harbor lead plant.
The oxygen bottom blowing technology can be used not only for the smelting of lead, but also for the smelting of precious metals such as copper smelting and gold and silver. At present, there are three domestically produced copper pipes in operation in the country, and four are being designed.
Yuguang technicians also found in practice that the process material has wide applicability and is particularly suitable for the treatment of recycled lead materials. Therefore, the successful application of this technology also put Yuguang on the development track of circular economy. Yuguang uses this technology and the integrated pretreatment technology of imported and used batteries CX imported from Italy, and has established two pretreatment production lines for used lead-acid batteries. The annual recycling of used lead-acid batteries is 360,000 tons, which has become the largest waste battery processing capacity in the world. The company was listed as the first circular economy pilot unit by the state.
The Deputy Governor Shi Jichun gave an instruction to the circular economy of Yuguang: “The circular economy is the foundation for the development and growth of the enterprise. Yuguang Gold and Lead are doing well in the recycling economy, turning waste into treasure, improving efficiency, comprehensive utilization, and saving resources. Get out of your own way."
â– liquid high lead slag direct reduction technology --- overall technology has reached the international advanced level in 2003, researchers began Yuguang liquid high lead slag direct reduction test new technology.
After more than five years of experimentation, Yuguang's liquid lead slag has been directly reduced to new technological innovations and granted patents for inventions.
On July 1, 2008, Yuguang launched a 80,000-ton melt smelting smelting plant to directly lead and lead the environmental protection project. It used a liquid lead slag to directly reduce the lead smelting process. On April 8, 2010, the 80,000t molten bath smelting furnace for direct lead smelting was successfully put into operation. On April 12, the lead outlet of the oxidation furnace was docked with the slag inlet of the reduction furnace. In the afternoon of the same day, lead was reduced from the reduction furnace. At 0:00 on the 13th, the reduction furnace slag. This marks the first direct lead-smelting production line in China.
On October 15, 2010, China Nonferrous Metals Industry Association organized the evaluation of Yuguang's “Research on the Direct Reduction Technology of Liquid High Lead Slag and Its Industrial Applicationâ€. The experts of the appraisal committee unanimously believed that the overall technology of the new technology for the direct reduction of lead in liquid lead slag of Yuguang reached the international advanced level. This achievement was listed as one of the ten low-carbon process technologies that the industry promoted in the 12th Five-Year Plan. With the promotion of this technology, China's lead smelting industry will surely set off an energy-saving storm, which is of great significance to the transformation and upgrading of the Chinese lead industry during the “12th Five-Year Plan†period. This achievement has recently won the first prize of the China Nonferrous Metals Industry Science and Technology Award.
Yang Guangguo, chairman of Yuguang, said: “From the advanced technology of lead conversion from liquid lead to the direct reduction of liquid lead slag, Yuguang has become the museum of lead smelting technology in China. The times are changing, the technology is improving, and Yuguang has gone from the gas to the past. The current clear water and blue sky interprets technological innovation as the eternal theme of corporate development and the social responsibility and historical mission that an entrepreneur should shoulder.â€
