Refined aluminum ingot for remelting
ICS 77.120.10
H61
People's Republic of China Nonferrous Metals Industry Standard
Remelting with fine aluminum ingots
2009-12-04 released
2010-06-01 Implementation
Issued by the Ministry of Industry and Information Technology of the People's Republic of China
Foreword
This standard is based on the international standard ISO 115..2003 "Refining aluminum ingot grades and chemical composition" to develop. Mainly with ISO 115.
Three grades in.2003. A199.995, A199.99, A199.98. In comparison, A199.995 in this standard is strictly ISO 115.
2003, A199.99 basically the same, A199.98 loose in ISO 115..2003.
The use of remelting with aluminum ingots should be fully preheated after the product added to the furnace (because of its surface shrink holes, holes in the water, fully warm
Can prevent the fine aluminum ingots in case of high temperature melt explosion).
This standard by the National Nonferrous Metals Standardization Technical Committee proposed and centralized.
This standard is responsible for drafting units. Xinjiang Zhonghe Co., Ltd., China Aluminum Co., Ltd. Guizhou Branch.
This standard participates in the drafting unit. Baotou Aluminum Company Limited.
The main drafters of this standard. Liu Jie, Zhai Xinsheng, He Xinguang, Song Yuping, Hong Tao, Zeng Ping, Gao Shulan, Yang Menggang, Cui Jian, Shen Qinghua.
Remelting with fine aluminum ingots
1 Scope
This standard specifies the requirements, test methods, inspection rules, packaging, marking, transportation and storage of fine aluminum ingots for remelting.
This standard applies to three layers of liquid electrolysis and segregation production of heavy aluminum ingots.

Note 1. The difference in the sum of the measured values of other impurities in the aluminum mass fraction of 100% and the impurity elements listed in the table and the mass fraction equal to or greater than 0.0010%
Value, the sum of the elements before the value to be expressed to 0.0 × × ×%, sum will be summed after the sum of 0.0 × × ×%.
Note 2. Lead, arsenic, cadmium, and mercury content of heavy metal elements not specified in the table shall not be subjected to routine analysis, but should be analyzed regularly and tested at least once a year
(Cd + Hg + Pb) ≤ 0.0095%, As ≤ 0.0090%. Other impurity elements are negotiated by both parties.
Note 3. The numerical analysis is carried out using the revision comparison method, according to the relevant provisions of the numerical correction rule GB/T 8170, chapter 3,
Limit number consistent.
