GB 21341-2017: Translated English of Chinese Standard. GB21341-2017: The Norm of Energy Consumption per Unit Product of Ferroalloy
https://www.chinesestandard.net, 30 mars 2018 - 12 pages
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.
