—Cold air technology and “non-contact metallurgy”
（Nanchang Engineering & Research Institute of Nonferrous Metals, Nanchang 330002, China）
Abstract: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.
Key words: flash smelting; cold air smelting; non-contact metallurgy; central swirling column flash smelting
