Production of globular fine iron powder

Production of globular fine iron powder

A process for producing iron oxide fine powder of high purity from an oxide iron ore such as hematite or magnetite by only physical processing is disclosed, which comprises the steps of: providing a preliminarily ground raw material powder of an oxide iron ore or a mixture thereof having the impurity content in a specific range; classifying the raw material iron ore powder under such

    May 18, 2018 The morphology of the ATOMET 1001 powder in Figure 2 b is characterized by a relatively homogenous particle size distribution and a rounded/globular particle shape without sharp edges. Moreover, single spherical particles are also observed. The ATOMET 4701 powder is characterized by a shape similar to that of ATOMET 1001

  • Production of Iron Powder by Solid-Phase Reduction of Fine Production of Iron Powder by Solid-Phase Reduction of Fine

    Jun 13, 2014 Since iron ore is subjected to fine grinding in the enrichment process, it seems to be more rational to produce iron powder by solid-phase reduction of iron ore concentrate rather than to employ the conventional process scheme: agglomeration → pig

  • Production of Fine Iron Ingot Using Iron Sand and Charcoal Production of Fine Iron Ingot Using Iron Sand and Charcoal

    The fine iron ingot was developed by the microwave oven heating using the iron sand and the charcoal powder. In the initial stage in which the heating time was 3-6 min, the iron sand changed into

    Thus for MIM, the chief concern is to have a very fine powder to promote high sintering activity. Typical specifications call for a median size of ~10 microns with a D90 of 20–30 microns. UHPWA can provide such a powder with a yield of 70–80% from the atomised powder. Gas atomisation struggles to provide more than a 50% yield
