Full copy of true-PDF in English version (including equations, symbols, images, flow-chart, tables, and figures etc.) will be manually/carefully translated upon your order.Calcined petroleum coke for prebaked anode ICS 71.100.10 Q52 People's Republic of China Nonferrous Metals Industry Standard Replacing YS/T 625-2007 After prebaked anode calcined petroleum coke Issued on. 2012-12-28 2013-06-01 implementation Ministry of Industry and Information Technology of the People's Republic of China released ForewordThis standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 625-2007 "carbon anode with calcined petroleum coke." This standard is YS/T 625-2007 amendments, the main amendments are. --- The ash grades DHJ-1 and DHJ-2 and of ≤0.30% ≤0.70% ≤0.40% were revised and ≤0.60%; --- The DHJ-1 grades in volatile ≤0.50% revised ≤0.7%; --- Sulfur grades DHJ-1 and DHJ-2 sub ≤1.80% ≤2.50% respectively and revised ≤1.8% and ≤3.0%; --- The grades DHJ-1 and the true density DHJ-2 ≥2.04g/cm3 and ≥2.01g/cm3 were revised to ≥2.05g/cm3 And ≥2.02g/cm3; --- The grades DHJ-1 and powder resistivity DHJ-2 of ≤530μΩ · m and ≤610μΩ · m were revised to ≤500μΩ · m And ≤600μΩ · m; --- Increased moisture conventional indicators; --- Increased CO2 reactivity and air reactivity, coke powder content (-2mm) 3 reference index. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is drafted by.
