Improving the control efficiency of metallurgical silicon production technology

摘要

The production of metallurgical silicon is characterized by the use of stationary units as ore-thermal furnaces. Such furnaces' operational difficulties are associated primarily with a low level of automated control and management. The present article is concerned with the features of the modern technological process for metallurgical silicon production. The following issue of concern in the production chain as the lack of moisture control of the reducing agent was identified. A method that implies a comprehensive approach to control both technological and energy parameters, in particular humidity, ash content and particle size distribution of the reducing agent is proposed as a recommendation. An algorithm for the operation of an automatic control system with the introduction of additional functions that improves the efficiency of the furnace unit has been developed and justified.
