Scope: This document stipulates the quota level, technical requirements, statistical scope and calculation method of energy consumption per unit product of ferroalloy (hereinafter referred to as energy consumption). This document applies to ferrosilicon produced by ferroalloy submerged arc furnaces, high-carbon ferromanganese produced by electric furnaces (limited to high-carbon ferromanganese produced by the flux-free smelting process), manganese-silicon alloys, low-carbon manganese-silicon alloys, high-carbon ferrochrome, and furnace charges Calculation and assessment of energy consumption per unit product of 9 varieties including micro-carbon ferromanganese produced by high-grade ferrochrome and ferroalloy refining electric furnace, medium (low) carbon ferrochrome and blast furnace ferromanganese produced by ferroalloy blast furnace, as well as evaluation of new construction, reconstruction and expansion projects Energy consumption control.
