LIFE18 ENV / DE / 000461 Project: "Pilot Line for the Production of Fine Spherical Iron Powders from Steel Producers` Products"

Reference Number: Supplier 1 ec AP 3.1 AP 4.1 AP 5.1

For a new process for producing fine spherical iron powders with a particle size of 15 μm, based on the granulation of iron oxide powder and subsequent reduction under hydrogen, A pilot line with a production capacity of up to 5 t per day for industrial scale production is to be upscaled. The starting material is an iron oxide powder with a Primaerpartikelgroesse in the range of 1 .mu.m, which is obtained from regenerated pickling sludge (waste product from the steel industry) can be used. The iron oxide is dispersed in a suspensionert, ground and then granulated to a size of 10-40 microns. The reduction takes place in a rotary kiln. Subsequently, the sinter cake is ground and sieved. The aim is to create a spherical particle shape.

AP 3.1.

AP 4.1.

A comprehensive analysis of all processing steps (reduction process, powder grinding and sieving) and the powder quaLitaeten in work package

2.1 should be carried out. These data are to be compared with the expected values including the defined LIFE key indicators. The material properties are tested in different phases of the process development and in the last phase of the project compared to benchmark powders. The specific powder properties can be too differentn Application objectives

The powder lead.

- In addition, the application-oriented results of the work package

3.1 are summarized and analyzed. These data are compared with those derived from commercial powder based sintered parts:

- dimensional and geometrical accuracy,

- microstructure,

- material density,

- mechanical behavior, e.g. B. Strength and hardness.

- The EThe efficiency, including the energy balances of the two developed production paths of different granule types (reduction and heat treatment dense and porous) is compared and evaluated in connection with possible powder applications. In particular, the effects of the continuous rotary kiln for oxide reduction on the efficiency of the powder production and the powder quality are in VerIt is important to participate in the analysis of technological risks.

Long-standing competence in the field of powder metallurgy and powder technology, powder processing and processing as well as experience in the reduction of iron oxide powder to iron powder is required and grinding to powder with spherical particlesTalt. Comprehensive analytics and laboratory equipment (particle size analysis, CNO gas analysis, flow behavior, SEM, metallography, hydrogen sintering unit, grinding units, sieve technology) must be present along the powder metallurgical process chain
