Reduced iron powder reduction process
Secondary refining process: sponge iron crushing magnetic separation → → → → cleaning powder reduction furnace II → solutions → crushed → → → classification of screening by magnetic separation → mix → package → finished product
Reduced iron powder for production of high quality, the parameters of standard, Fe ≥ 98%, carbon 0.01%, p and s are less than 0.03%, hydrogen damage of 0.1~0.2%.
The main use of reduced iron powder:
Reduced iron powder powder metallurgy products, the industry consumed the amount of reduced iron powder by 60%~80%
Welding electrodes with reduced iron powder, iron powder can be added to the coating 10~70% improved electrode process and greatly enhance the deposition efficiency
Reduced iron powder for chemical industry, mainly for chemical catalysts, precious metals restored, additive in alloy and copper replacement
Iron powder for cutting stainless steel, cutting steel products, iron powder oxy-acetylene flame spray can improve cutting performance, broaden the scope of cutting steel grades, improved cutting thickness
The continuous improvement of technology of powder metallurgy industry in China, being widely used powder metallurgy parts and planes, guns, motorcycles, family car, automobile, agricultural machinery, mining, electric power tools, machine tools, transport and other machinery industry, with the rapid development of China's economy, reduced iron powder in the yearly rise.
