摘要
文章描述了工业硅生产的工艺流程,阐述了行业目前普遍炉型偏小、自动化程度低、环保措施简陋、能耗居高的生产现状,介绍了近些年涌现的矿热炉大型化、炉内旋转布料、自动开堵眼、烟气治理、定点浇铸、闭式循环等先进技术,揭示了未来可能发展的一些方向.
Abstract
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.
