Ministry of Industry and Information Technology of the People's Republic of China released
Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 287-2005 "semi-graphite aluminum electrolysis cathode block" and YS/T 623-2007 "high graphite aluminum electrolysis
Cathode block. "
This standard YS/T 287-2005 and YS/T 623-2007 compared to major differences are.
--- Semi-graphitic cathode carbon block and high-grade graphite cathode block the merger, and each re-grade products were prescribed;
--- Indicators of the thermal expansion coefficient and sodium expansion rate index harmonization canceled electrolysis expansion indicators;
--- For true density, compressive strength, apparent density and resistivity at room temperature has been revised;
--- Deleted YS/T 287-2005 in porosity index, BSL-2 grades, and Appendices A and B;
--- Increased GS-C side carbon block grades;
--- Increased side carbon block reference index project.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Aluminum Corporation of China Guizhou Branch, CPI Ningxia Energy Aluminum Ching-hsin Carbon Co.
Secretary, Shandong Yankuang Carbon Products Co., Ltd., Shanxi Jinyang Carbon Co., Ltd., Yunnan Aluminum Co., Ltd., Ningxia Ning have flat carbon
Limited liability company, Zhengzhou Haoyu Carbon Materials Co., Ltd.
Participated in the drafting of this standard. Shanxi Shanxi Carbon Co., Ltd. Fangyuan Group Co., Ltd. Lushan new lining material.
