Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard replaced GB 21341-2008 The Norm of Energy Consumption per Unit
Product of Ferroalloy. Compared with GB 21341-2008, this Standard has the major
technical changes as follows besides the editorial modifications.
--- Add the energy consumption limit level;
--- Delete the advanced value of energy consumption and energy conservation
management and measures;
--- Retain the energy consumption limit index of power equivalent value under the
conversion factor, which is revised; cancel the energy consumption limit index of
power equal value under conversion factor;
--- Supplement and improve the “electro-furnace ferromanganese” by “electro-
furnace high-carbon ferromanganese”; define it as the smelting process of flux-
free method (or less flux method);
--- Supplement and improve the definitions of “comprehensive energy consumption
per unit product of ferroalloy” and “smelting electricity consumption per unit
product of ferroalloy”;
--- Add the definition, statistical range and calculation formula of “coke consumption
per unit product of ferroalloy”;
--- Modify the calculation formula of “smelting electricity consumption per unit
product of ferroalloy”;
--- Modify the capacity requirements for the newly-reconstructed ferroalloy ore
furnace, and the terms of refining furnace;
--- Supplement and improve the “statistical range”;
--- Propose the value-taking principle for the energy conversion coefficient and
modify the corresponding recommended value.
This Standard was proposed by Resource Conservation and Environment Protection
Department of National Development and Reform Commission, and MIIT’s
Department of Energy Conservation and Comprehensive Utilization.
This Standard shall be under the jurisdiction of Standardization Administration of the
People’s Republic of China.
The Norm of Energy Consumption
per Unit Product of Ferroalloy
1 Scope
This Standard specifies the terms and definitions, technical requirements, statistical
range and calculation method of the norm of energy consumption per unit product of
ferroalloy (hereinafter referred to as energy consumption).
This Standard is applicable to the calculation and audit of per unit energy consumption
for the following 5 kinds of products such as ferrosilicon produced in the ferroalloy ore
furnace, high-carbon ferromanganese in electro-furnace (only limited to the high-
carbon ferromanganese adopting the smelting process of flux-free method or less flux
method), manganese-silicon alloy, high-carbon ferrochrome and ferromanganese in
the blast furnace produced by ferroalloy blast furnace, as well as the energy
consumption control for the newly-built or re-built projects.
