GB 21341-2008

This standard specifies the technical requirements, statistical scope, and calculation methods for the energy consumption (hereinafter referred to as "energy consumption") limits of unit products of ferroalloys, as well as energy-saving management and measures. This standard applies to the calculation and assessment of energy consumption limits of unit products of five major products produced by reduction electric furnaces (mineral hot furnaces), including silicon iron, high-carbon manganese iron (electric furnace manganese iron), manganese-silicon alloy, high-carbon chromium iron, and manganese iron (high-carbon manganese iron) produced by blast furnaces. It also applies to the energy consumption control of newly built equipment. Other ferroalloy products may be implemented in accordance with this standard.
