Latest Patents

Lummer holds a patent for a process titled "Making iron powder." This invention 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 process is characterized by a half cone angle between 40 and 60 degrees, preferably at 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, leading to a powder with a particle size distribution that contains a higher proportion of larger particles than the powder produced immediately from atomization.

Career Highlights

Richard Lummer is associated with Mannesmann Aktiengesellschaft, a prominent company in the field of materials and engineering. His work has been instrumental in advancing the production techniques of iron powder, which is essential for various industrial applications.
