Title: Norbert Dautzenberg: Innovator in Powder Metallurgy
Introduction
Norbert Dautzenberg is a notable inventor based in Meerbusch, Germany. He has made significant contributions to the field of powder metallurgy, particularly in the production of iron powder. With a total of 5 patents to his name, Dautzenberg's work has had a lasting impact on various industrial applications.
Latest Patents
One of Dautzenberg's latest patents is a process for preparing a powder mixture and its use in making iron powder. This innovative method 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, creating a pressure of 0.02 to 0.20 bars below ambient. The resulting 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 compared to the powder produced immediately from atomization.
Career Highlights
Throughout his career, Dautzenberg has worked with prominent companies in the industry. Notably, he has been associated with Mannesmann Aktiengesellschaft and Nederlandsche Wapen-en Munitiefabriek De Kruithoorn N.V. His expertise in powder metallurgy has been instrumental in advancing the technologies used in these organizations.
Collaborations
Dautzenberg has collaborated with several notable individuals in his field, including Josef Hewing and Max Michalke. These partnerships have contributed to the development of innovative solutions in powder metallurgy.
Conclusion
Norbert Dautzenberg's contributions to the field of powder metallurgy, particularly through his patented processes, highlight his role as a significant inventor. His work continues to influence the industry and pave the way for future innovations.
