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.
