Iron Powder Development Prospects Are Broad, Optimistic

China's iron ore is rich in resources, but most of the iron ore resources are low iron grade, high impurity content, embedded in the fine size of the hematite ore type, this part of the ore selection of the selected process is more complex, sorting indicators Lower. In some of the iron and steel and metallurgical production in the production of waste residue, containing relatively high grade of iron, this part of the large amount of waste into the formation of open pit. Not only take up a lot of land resources, but also cause environmental pollution.


Iron powder is an important raw material for powder metallurgy. The industrial preparation and application of iron powder began in the 1920s. At that time, Germany produced electrolytic iron powder and carbonyl iron powder, mainly used as a chemical industry catalyst. 30 years began to produce powder metallurgy iron-based parts. 1933 Germany developed a vortex grinding method to produce iron powder. 1936 Sweden in the production of sponge iron on the basis of the reduction method from the magnetite to produce low-cost iron powder. After the 40s in Germany, Britain, the United States and other countries and the emergence of molten metal atomization method of manufacturing iron powder, and on this basis, the rapid advance of the production of atomized pre-alloy powder. China began in 1958 with the reduction of iron production, 60 years began to use atomization method to develop a variety of alloy and alloy steel powder.


In recent years, iron powder production, application, research and other aspects have developed rapidly, reflecting China has a certain production capacity and technical level. But with the rapid development of China's economy, can not meet the needs of machinery and equipment construction, in terms of depth or breadth, there is still a certain gap, to improve the quality of existing products under the premise of further development of new products, The In all parts of the country, especially in the southeast coastal area, iron powder application potential is great, iron powder development prospects are broad, optimistic.


With the rapid development of China's industry, all walks of life on the demand for iron powder is growing, but China's iron powder technology is far less than abroad, so some areas still rely on import development.


In recent years, some of the reduction of iron ore manufacturers in order to meet market demand, and actively improve the technology, so that China's iron powder production has greatly improved. Iron powder is the most important and most widely used and low-cost metal materials in modern industry. In the future for a long period of time, the reduction of iron powder industry will be the survival and development of society as an important material basis.
