The overall trend of the iron powder production in the world has been steadily increasing

Iron powder is the basic raw material of powder metallurgy industry. The world produces more than one million tons of
iron powder every year, and our country already has over 300,000 tons of production capacity. Production of reduced iron
powder 60%, mainly distributed in Anshan iron and steel group co., LTD., Wugang, Magang and other large steel
enterprises have the super iron ore concentrate powder production enterprises. The production and quality of iron powder
directly affect the development of powder metallurgy industry and magnetic material industry. In turn, it directly affects
many industries such as automobile, electromechanical, electrical appliances, communication, machinery manufacturing,
etc. It is well known that when making mechanical parts with iron powder, the material utilization rate is more than 95%,
while the material utilization rate is about 45% for CNC machining. Internationally, it is thought that a tonne of iron
powder is equivalent to three tons of steel.
The iron powder reduction method is used to produce the production of organic products in the process of the production
of the iron and black iron, which is the process of reducing, filtering, washing, sifting, filtration and drying. The
reduction process of the above process is carried out by the reduction reaction tank with the paddle mixer, and the iron
powder, water and reaction medium are put into the tank. Indirect heating steam iron powder slurry, activation 0.5 1 hour
continuously drip organic material, reduced iron powder intermittent iron powder, in the process of reaction media and
water, and always maintain the organic material. The amount of iron powder, reaction medium and water is 1:0.5-
1.5:0.01-0.1:2-5. The suspension of the organic product and the iron clay is continuously produced from the outlet of the
reduction reaction tank. The invention can realize continuous production, reduce consumption and improve resource
utilization. The process of producing organic products with iron powder as a reducer in iron powder can be used in the
process of making organic products.
With the development of economy and technology, the automobile industry fluctuation, the world iron powder overall
trend has been steadily rising. The fluctuation ranges from 8%t to 10%, with a peak of 850,000 t and low ebb 780,000 t.
However, the use of powder metallurgical parts in a single car is increasing. Although car production is fluctuating, the
total production of iron powder will not be below 850,000 t, and there will be a surplus of capacity before the new
process emerges. The production of iron powder in China is expected to reach 150,000 t in the next five to seven years,
based on the following considerations: First, with the development of the automobile industry, the weight of domestic
powder metallurgical parts in each car should rise from about 3.6 KG to about 5KG. Secondly, the application of powder
metallurgical parts in the automotive industry should rise from about 42% to about 55%. Finally, the use of magnetic
materials should eventually be at 20,000 t, and the export volume should be between 15,000-20,000 t.
