Abstract: in article questions of balance of a consumption of energy resources of the entities used in metallurgical are considered. It is analyzed consumption and use of energy resources by energy types (an example of the electric power and gas). By means of the energy balance consumed energy resources an opportunity comes to light and specific actions in the field of rational energy use are planned. The share of electricity consumption and gas in shops of ferrous metallurgy is determined. The cartogram of electricity consumption and gas is brought and analyzed.
Keywords: melting, hire of camps, engineering procedure, gas, electric power.

Аннотация: в статье рассматриваются вопросы баланса расхода энергоресурсов, используемых в металлургических предприятиях. Анализируются потребление и использование энергоресурсов по видам энергии (на примере электроэнергии и газа). С помощью энергетического баланса потребляемых энергоресурсов выявляется возможность и намечаются конкретные мероприятия в области рационального использования энергии. Определяется доля потребления электроэнергии и газа в цехах черной металлургии. Приводится и анализируется картограмма потребления электроэнергии и газа.
Ключевые слова: плавление, прокат станов, технологический процесс, газ, электроэнергия.
The most complete characterization of the complex state of the energy sector can be obtained from a study of the energy balance, which is the basis for the analysis of current state and means of rationalization of energy consumption, measures of forecast estimates. The energy balance provides an indication of the structure and efficiency of production, conversion and use of energy, fuel and energy for the production of major products, correlation to major material balances of the enterprise. Energy balance of industrial enterprises is the subject of many studies in the CIS countries and abroad.
The basis for establishing norms of specific consumption of energy per unit of output in the iron and steel enterprises are the energy consumption balances by expenditures and loss sites.Balance of energy consumption clearly and fully reveals the structure of the energy consumption of technology operation, shop and enterprise characterizes the level of energy use.To compose the balance sheet of energy special tests of power equipment are conducted,

components of the energy consumption is estimated by individual shops and enterprises, the energy accounting and non-recurring measurements are being held [1].
With the help of energy balance we reveal the possibility and outline specific activities in the field of energy management.
At the enterprises of ferrous metallurgy in process raw materials and semi-finished products go through a series of operations, ie, melting, rolling mills etc; each operation is meant to perform a particular process.
At the enterprises of ferrous metallurgy in the process of processing the raw materials pass through a series of operations, i.e., melting, rolling mills, each operation is meant to perform a particular process.
From the analysis of the figure 1 we see that the main consumers of electricity are the electric arc production which consumes 40% percent of electricity and the production of rolling mills, which use, respectively, 16,6% of the total electricity consumption.
The high specific weight of electricity in smelting steel enterprises is due to the melting of steel in electric arc furnaces [2].
In heat consumption in the steel industry the most heat is consumed by bar-rolling production, which stands for 56% of the total gas consumption.
