Status Quo and Development Trend of Industrial Silicon Industry
This paper describes the technological process of industrial silicon production,expounds the current production dominated by small furnace type,low degree of automation,simple environmental protection meas-ures and high energy consumption in the industry as well as introduces advanced emerging technologies in recent years such as large-scale submerged arc furnace,rotary material distribution in furnace,automatic hole open-ing and plugging,flue gas treatment,fixed point casting and closed circulating and provides some possible de-velopment trends in the future.
