Ferromanganese ICS 77.100 H42 National Standards of People's Republic of China Replacing GB/T 3795-2006 Ferromanganese Issued on. 2014-09-30 2015-05-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released

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. Ferromanganese

1 Scope

This standard specifies the product classifications, technical requirements, test methods, inspection rules and packaging, storage and transportation, marking and certification of ferromanganese. This standard applies to steelmaking, casting deoxidizer and alloying elements additives ferromanganese.

3 Product Categories

3.1 By refining different ways, divided into ferromanganese and blast furnace ferromanganese. 3.2 according to carbon content, divided into four categories. --- Micro carbon-based. not more than 0.15% carbon; --- Carbon categories. carbon greater than 0.15 to 0.7 percent; --- Carbon categories. carbon greater than 0.7 to 2.0%; --- High Carbon categories. carbon greater than 2.0 to 8.0%. 3.3 by silicon, phosphorus, divided into two groups. Ⅰ, Ⅱ.
