Аnalysis of the state of automation of material flow control in silicon production
The problem of material flow control has a key significance in the silicon production since the proportional composition of furnace-charges (specific gravity, taking into account moisture) and current state of the furnace (slagging and etc.) essentially affect the yield and quality of the finished product, and the efficiency of the technological process as a whole. The relevance of the topic lies in the need to modernize and increase the level of transparency of production processes in the silicon industry. In this analytical review, the following tasks have been solved: the suitability of using automated material flow control systems in the silicon production has been proved; the bottlenecks of the process in terms of saving resources have been identified; the functionality of the automated material flows control system has been determined by means of examples of similar production; the method of control of emissions of valuable components has been put forward; the functional structure of the automated control system of the highest production level for the company “Silarus” has been proposed. This article examines the state of automated material control systems in the silicon production. The reasons for the introduction of such systems have been substantiated by the example of ferroalloy production. The general principles of the organization of automated systems of the factory operation of the largest foreign silicon enterprises, and their role in the accounting and management of material flows have been determined. A method for controlling the quality of microsilica capture has been proposed.
