Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 3795-2006 "ferromanganese."
This standard compared with GB/T 3795-2006, mainly on the technical content of the following changes.
--- Micro-carbon ferromanganese furnace increases the categories;
--- Reduce the major impurity element phosphorus, silicon content, improve the standard level;
--- The product size range has been adjusted.
The standard proposed by China Iron and Steel Association.
This standard by the national pig iron and ferroalloy Standardization Technical Committee (SAC/TC318) centralized.
This standard was drafted. Shanxi Jiaocheng Yiwang ferroalloy limited liability company, Shanxi Eastern Resources Development Co., Ltd., Metallurgical Industry Information
Standards Research Institute.
The main drafters of this standard. Le Song Jin, Kang Guozhu, WANG Cheng-guo, Shuli.
This standard replaces the standards previously issued as follows.
--- GB 3795-1983, GB 3795-1987, GB/T 3795-1996, GB/T 3795-2006.
