Scope

This document specifies the levels, technical requirements, statistical scopes and calculation
methods for the norm of energy consumption per unit product of ferroalloy (hereinafter referred
to as energy consumption).
This document is applicable to the calculation and assessment of energy consumption per unit
product of 9 varieties: ferrosilicon produced by ferroalloy submerged arc furnaces, high carbon
ferromanganese produced by electric furnaces (limited to high carbon ferromanganese
produced through the flux-free smelting process), manganese-silicon alloy, low carbon
ferromanganese-silicon, high carbon ferrochromium and charge ferrochromium, and micro-
carbon ferromanganese and medium (low) carbon ferrochromium produced by electric
ferroalloy refining furnaces, and blast furnace ferromanganese produced by ferroalloy blast
furnace, as well as the energy consumption control of new construction, renovation and
extension projects.
