Iron Powder Is An Important Powder



Iron Powder is an important Powder

Iron Powder color: black. It is the main raw material of powder metallurgy. According to the granularity, the habit is divided into coarse powder, medium powder, fine powder, fine powder and super fine powder. The particle size of the particle size of 150-500 mu m is the coarse powder, the particle size is 44 ~ 150 mu m is medium powder, 10 ~ 44 mu m is fine powder, 0.5 ~ 10 mu m is very fine powder, less than 0.5 mu m is super fine powder. General will 325 target quasi screen by particle size less than 44 microns powder called the sieve, if want to undertake higher precision screen divided we can only use air classification equipment, but for some easy oxidation of Iron Powder JZDF nitrogen protection classifier is used to do. Iron Powder mainly includes reducing Iron Powder and atomized Iron Powder, which is named for different modes of production.

Iron Powder is the most important Iron Powder in the powder cure gold industry. It consumes about 85% of the total powder consumption, and the main market of Iron Powder is to make mechanical parts, which account for about 80% of the Iron Powder.

Iron Powder is the primary material of powder metallurgy. According to the grain size, it is divided into five grades: coarse powder, medium powder, fine powder, fine powder and ultrafine powder. The particle size of the particles in the range of 150 ~ 500 mu m is the coarse powder, the particle size is 44 ~ 150 mu m is medium powder, 10 ~ 44 mu m is fine powder, 0.5 ~ 10 mu m is very fine powder, less than 0.5 mu m is super fine powder. Will usually through the sieve is 325 mesh specification size less than 44 microns powder called the sieve, if want to undertake higher precision screen divided we can only use air classification equipment, but about some easy oxidation of Iron Powder JZDF nitrogen maintenance classifier is used to do. Iron Powder is the first to include reducing Iron Powder and atomized Iron Powder, which is named for different production methods.

Pure iron is silvery white metal, Iron Powder is black, it is a optical question, because the Iron Powder surface area is small, have no fixed geometry, and the crystal structure of iron geometric shape, therefore iron to absorb some of the visible light, will be another some visible light out of the mirror, show white; The light that has not been absorbed by the Iron Powder has been reflected, so it can enter the visible light of the human eye, so it is black. Today, we are going to introduce the operation and storage of Iron Powder.

Iron Powder operation notice: airtight operation, part of the exhaust air. Iron Powder operator is necessary through special training, strictly abide by the operation procedures. Advocate operators wear self-priming filter type dust mask, wearing chemical safety protective glasses, wear rubber resistant to acid and alkali, wear rubber gloves resistant to acid and alkali. Away from flammable and combustible. Avoid dust. Avoid with alkali, alcohol touch. Pay particular attention to avoid to touch water. Transfer to light light discharge, prevent damage of packaging and container. Equipped with leakage emergency handling equipment. Empty containers may be residual hazards.

Iron Powder storage precautions: store in a cool, dry, ventilated outstanding warehouse. Stay away from fire and heat source. Remain below 75% relative humidity. Iron Powder packing seal is necessary, don't be affected with damp be affected with damp. Should work with yi (can) combustion content, alkali, alcohol such as hosting space, avoid by all means is mixed store. Shoulds not be long, avoid bad. Storage area shall be equipped with appropriate leaked the information received.

Iron Powder is the fine powder of iron ore. In theory, ore that contains iron or iron compounds can be called iron ore. However, in industry or commercially, iron ore is not only a component of iron but also of value to be used.

Since in the early 1930 s Iron Powder for powder metallurgy industry, has attained a lot of Iron Powder production methods. Due to the various reasons of technology and economy, many of them have never been beyond the experiment or pilot stage, for example with hot hydrogen reduction of ferrous chloride chemical metallurgical method; Other methods, such as mechanical FenSuiFa vortex and aqueous solution electrolysis, fluidized bed hydrogen reduction method, rotating disk atomization of liquid steel, air atomizing liquid iron and conversion of natural gas and solid carbon reduction method and so on, through the industrial application of a relatively short time, and then for other more competitive method is no longer used in the industrial production of Iron Powder. As for the production of Iron Powder with carbonyl method (see carbonyl powder method), because of the fine particles, are expensive, is not suitable for sintering machine parts and welding electrode; But its high purity, particle structure, special shows excellent performance. Now dominate the market of Iron Powder of Iron Powder production process is: belongs to the iron oxide reduction process, and sent the long method of herge, low carbon steel liquid water atomization method, belong to high purity iron shot peening of ball mill and decarburization process QMP method and r); The amount of Iron Powder produced by hgneras and water atomization is overwhelming.
