Recently, the Chinese Academy of Engineering Zhang Wenhai, published paper entitled "heavy metal colored short process metallurgy industrial energy-saving technology development," pointed out that to achieve "low consumption, low emission, high efficiency," the short process of energy-saving metallurgy, non-ferrous metals industry is already the current implementation The urgent issue of the scientific concept of development. Zhang Wenhai analyzed the development status and existing deficiencies of China's non-ferrous metal industry technology, and studied the development of flash continuous copper smelting process, the development of flash furnace smelting process, the development of vortex column concentrate nozzles, and the high melting point of flash furnaces. High thermal conductivity overall cast copper-based alloy water jacket R&D, flash metallurgical online safety monitoring and accident warning information system R&D and other five aspects, discussed in detail the metallurgical industry technology innovation direction.
He pointed out that China's overall energy consumption of non-ferrous metals yield higher than the international advanced level in more than 15%, China to achieve 40% to 45% of the commitment to reduce energy consumption per unit of GDP in 2020, it is necessary for the principle of non-ferrous metallurgy heavy metal and process characteristics, There are major innovations in the metallurgical process, research and development of energy saving and environmental protection technologies and devices to solve the common problems of energy conservation and emission reduction. Zhang Wenhai believes that it is necessary to develop a "short flash continuous smelting" short process new process by integrating advanced technologies such as "flash smelting" and "continuous blowing" to realize two processes of smelting and blowing in a single smelting plant. In order to reduce the overall energy consumption of copper smelting, the problem of low-level dioxide* pollution caused by PS converters is completely solved. Wenhai said that China's long-term cooling water jacket behind in terms of development and controlled abroad, so far all the enterprises are still using copper water jacket, production safety problems become problems nonferrous metallurgy industry wide attention, and actively explore the tungsten, molybdenum, rare earth and other rare elements on the performance of copper-based alloys, development of independent intellectual property rights have a high melting point, high thermal conductivity copper alloy, developed cooling water jacket overall casting technology, the formation of a cooling water jacket core technology and competitiveness, foreign occupation water Sets of markets have far-reaching theoretical significance and broad application value. Zhang Wenhai believes that the flash furnace one-step smelting lead process independently developed by China is a direct lead smelting new process in which flash smelting smelting technology and liquid lead slag direct reduction technology are applied to lead smelting, and the new short-flow process smelting lead smelting technology has been successful. R&D and industrial applications will certainly greatly enhance the overall technological equipment and competitiveness of China's lead smelting industry.
