闪速熔炼在中国的进展与研究——冷风技术及“非接触冶金”

Progress and research of flash smelting in China ——Cold air technology and "non-contact metallurgy

从环境保护角度阐述了世界铜、镍闪速熔炼的发展与现状,讨论了"冷风节能"及其工业应用技术。介绍了中国在"闪速炉扩产"、"闪速冶金事故监控"、"水套新材料"、"闪速炉连续炼铜"等方面的研究成果。为根本解决强化冶金对炉衬的腐蚀,提出了"非接触冶金"的思路,描述了中心旋涡柱闪速熔炼方法,并介绍了旋涡喷嘴基本设计及计算机仿真实验。

From the viewpoint of environmental protection, international development and present situation of copper and nickel flash metallurgy were expatiated, cold air energy saving and its industrial application technique were discussed. The studies in China on the parts of limit of production expansion for flash furnace, monitoring for accidents in flash metallurgy, new material of water jacket and continuous copper smelting by flash furnace were introduced. To fundamentally solve the problem of corrosion to furnace liner by intensified metallurgy, the idea of non-contact metallurgy was put forward. The flash smelting method of central swirling column was described, and the basic design of swirl nozzle and computer simulation experiment was introduced.
