Discussion on Technical Status and Improvement Measures for Sponge Titanium Production in China

This paper reviews technical status of sponge titanium production in china.After comparing technology and technique-economy indexes for five steps of sponge titanium production in world,the improvement measures are proposed to be taken to reach international advanced level of sponge titanium production in china as following : to dispose soot dust of high-titanium slag production for improving operation condition and replace some hand operation by auto-control machine operation;to improve feeding method of chlorination charging and to achieve computer control of the fluidized chlorination;to replace the copper thread process of removing vanadium from titanium tetrachloride by aluminum powder process with one step method;To increase greatly the quality of sponge titanium in reduction-distillation step;to select the poly-polar electrolysis bath for magnesium electrolysis rather than the electrolysis bath without separating board.
