Approach. The majority of engineering and technical personnel of the company have obtained a large number of heavyweight scientific and technological achievements through technological innovation, technological development, and technological breakthroughs, which have strengthened the strength of the company and promoted the sustained, rapid, and healthy development of Chinalco and Guizhou enterprises. Actively innovate independently and create a series of technologies and products that lead the development of the industry In the science and technology work, Guiyang has established a foothold in independent innovation, continuously improves its leading edge, and firmly grasps globally and strategic projects. It has newly established 32 projects in 3 years. , achieved 296 technical innovations. Major breakthroughs have been made in the areas of bauxite mining, reduction of alumina consumption, energy saving of electrolytic aluminum, direct aluminum casting of high performance aluminum alloys, carbon production and production reduction, and recycling and utilization of aluminum industrial wastewater. , pioneered a series of technologies that lead the development of the industry. We have also developed a series of products led by the industry, represented by alumina, alloy slabs, new high-strength cast aluminum alloys, carbon products, and anode trailers. In the past three years, through technological development and technological breakthroughs, 78 key technical and economic indicators such as alumina, electrolytic aluminum, carbon, thermoelectricity, transportation, profiles, and environmental protection have been comprehensively improved. The economic benefits of the company have been significant, further enhancing and consolidating the precious aluminum. The status of China Aluminum Industry. Combining production, education and research, we have obtained a number of industry-recognized R&D achievements to improve the strategic layout of production, education and research, and expand the scope of science and technology cooperation. Guiyang has established strategic alliances with major domestic universities, research institutes, and famous enterprises, and signed strategic cooperation agreements. , Actively carry out research cooperation. The implementation of "strong and strong" alliances has enhanced the quality and level of corporate R&D projects and accelerated the transformation of scientific and technological achievements into practical productivity. A number of achievements have been made, and the results of the industry's landmark R&D projects have been achieved. The research project of underground mining prevention and control of bauxite bauxite in Guizhou solves the problem of mining of deep ore bodies; through research and development, a composite additive for desulfurization and organic removal is solved, and the problem of black and gray bauxite mining for alumina production is solved; China took the lead in the successful development of a plate-type falling film evaporation process simulation system for alumina production, which further stabilized the feed volume and increased the evaporator operation rate, creating favorable conditions for alumina production and production. The DJYF-II type electrolysis process system optimization research and application project has developed a control technology for stabilizing the cell condition and improving the electrolysis efficiency under the condition of intensified current, which has filled the blank of this domestic technology. The new technology of asphalt flue gas treatment in the carbon production process has reduced the content of asphalt flue gas in the anode forming process to nearly zero emissions. This not only improves the working environment, but also is significant in energy conservation and emission reduction. Using patented technology to accelerate the development of new products to meet market demand In the development of new products, Alcoa based on the market demand, pays attention to improving the technical content of products, especially the development of products with independent intellectual property rights, strengthening the use and protection of intellectual property rights, effective Strengthen the company's market core competitiveness. The high-strength cast aluminum alloy products developed by the Guizhou Aluminum Plant have reached international advanced level in mechanical properties. The high strength, high elongation, low cost and excellent casting performance of the products are favored by the domestic aerospace industry. The successful development of this product broadens the application field of high-strength aluminum alloys, fills the domestic gap, and has good social and economic prospects. The aluminum alloy product development of the Guizhou branch company has developed to high-tech, high-quality, and high-yield products and has achieved remarkable results. In the past three years, the branch newly developed and produced a series of high-end aluminum alloy products such as PS1050, 3104, 5754, CTP slabs and 7005, 6n01 round ingots, and 6201 alloy poles, bringing significant economic benefits to the company. At present, high-tech and high-value-added new products have accounted for more than half of the sales of aluminum products for enterprises, and have contributed greatly to the company's efforts to seize the market and resist market risks. While vigorously promoting independent innovation, companies attach great importance to the intellectualization and industrialization of results. Guizhou Aluminium Plant and Guizhou Branch now have 277 patents, most of which are invention patents and 158 nationally authorized patents. The number of applications for patents and standards is ranked first in the industry in China. Accelerating the transformation of achievements, helping to overcome technological bottlenecks in the production process, accelerating the transformation of scientific and technological achievements, conquering the technological bottlenecks in the production of technological difficulties, and improving production efficiency are the strategic priorities of Guizhou Aluminum for accelerating technological advancement and seeking sustainable development. In the past three years, the Guizhou branch has been working on the key processes of electrolysis, alumina, and carbon production to break the bottleneck that restricts production and achieved breakthrough results. The “Bayer-Sinter combined flow and combined desilication process research and application” project in alumina production creatively merged the sintering desiliconization slurry with Bayer-dissolved ore pulp, eliminating the need for medium-pressure desilication and other processes, simplifying the process and reducing consumption. The high-concentration continuous carbonation decomposition production of alumina technology research project achieved a new concentration of semen continuous carbon segregation, improved alumina product quality, and stabilized production. The “Reuse of spent cathode carbon material after electrolysis cell overhaul” for resource utilization of spent cathode carbon was developed, and the spent cathode was replaced with raw material to add coal for alumina production, achieving waste cathode carbon material without Harmful treatment has solved the problem of disposal of carbon solid waste. The Guizhou branch also used the giant geotechnical woven bag hydraulic irrigation and fly ash technology for the construction of the metallurgical tailings dam and the grey storage dam of the thermal power plant ash storage site for the first time, which not only increased the ash-laden dam of the tailings dam. The capacity of storage capacity has enabled the comprehensive utilization of solid waste and solved the environmental protection problem of red mud waste.
