Latest Patents

Dieter Bernhardt holds a patent for a method of making iron powder. This process involves atomizing a stream of molten steel using a conical jet of water at a rate exceeding 10 cubic meters of water per metric ton of steel. The half cone angle is maintained between 40 and 60 degrees, with a preference for 45 degrees. Additionally, air suction is applied upstream from the cone, adjacent to the stream, at a pressure of 0.02 to 0.20 bars below ambient. The resulting iron powder is reduced at temperatures ranging from 1,000°C to 1,200°C, and the resulting cake is broken up to achieve a powder with a particle size distribution that contains a higher proportion of larger particles than the powder produced immediately from the atomization.
