Economic efficiency of automated control system on the example of a vacuum arc furnace in the steelmaking shop JSC «Metallurgical Plant «Electrostal»

In order to explore the possibility to reduce energy costs and waste , as well to increasing the quality of melted ingots , the vacuum arc furnace DVS-3.2-G1 in the steelmaking shop of JSC «Metallurgical Plant «Electrostal» has been modernized. The calculations of the cost of waste, electricity and wages, as well as of cost price including depreciation before and after the modernization of management system are presented. The diagram of financial flow, calculations of net present value over the years, as well as after the first and second iteration are presented. Data of the economic efficiency of the vacuum arc furnace automatization from 2014 to 2016 are presented. The article presents data of economic efficiency, estimates the cost of developing and implementing of the automated process control system. Established is the economic feasibility of the introduction of automatic process control on other vacuum arc furnaces in JSC «Metallurgical Plant «Electrostal».
