[Titanium]Panzhihua responsible for the development of the "TR" national standards formally promulgated

Learned from Pangang Group, by Pangang responsible for the development of the "TR" (GB/T3282-2006) national standards, from the State Standardization Management Commission formally promulgated.
TR is the steelmaking alloy material production and use of the additive, and its main purpose is four. One is used for steelmaking Deoxidizer, with the exception of gas agent. Titanium deoxy much higher than the capacity of silicon, manganese, steel ingot reduce segregation and improve the quality of steel ingot and improve recovery rate. 2 is used for alloying agent. Special steel production of the main raw material, it will increase the strength of steel, corrosion resistance and stability, which is widely used in stainless steel, Tools such as steel production. 3 is to improve the performance of cast iron. For the foundry industry to improve the wear resistance of cast iron, stability, processing and so on. 4 is used for welding titanium, calcium-based coating raw materials.
"TR" national standards in the original 1987 implementation. Industry experts pointed out that by the time production techniques and conditions of use restrictions, the original standard includes only four brands of products, has been unable to meet national science and technology and economic development needs. With China's accession to the WTO, this standard has been difficult to adapt to economic globalization competitive situation, the original standards of a number of technical indicators and the need for closer international advanced standards under the conditions be amended. The original standards of product testing method it is necessary to make amendments to supplement and perfect. Therefore, the state standards committee in 2003 specifically below, has been set up by China's largest titanium raw materials base of Panzhihua, revision of GB/T3282-1987 "TR" standard.
Pangang established a special "TR" standard drafting team, and in April 2004, TR related to the domestic production, use and research units issued "of seeking" TR "amendments to the standard letter." Extensive revision on the basis of Panzhihua collection, retrieval influential at home and abroad "TR" standard, and make progress develop a new "TR" the national standard.
New "TR" There are many national standards innovation. TR brands in the installation, the new standards set up six brands, more than the old standards of the two brands. which covers 70 TR. TR 70 is widespread international use of the TR varieties and the beginning of this century China has successfully developed and started mass production of 70 TR well users, it is therefore necessary to include standards. New standards also of the original brands TR chemical ingredients made some adjustments. The revised standard brands TR the main chemical components and the original standards, compared to the international standards, indicators more scientific and rational.
