Title: Innovations by Hanspeter Krahenbuhl
Introduction
Hanspeter Krahenbuhl is a notable inventor based in Kreuzlingen, Switzerland. He has made significant contributions to the field of lubrication and cleaning processes for rolling oils and lubricants. With a total of 2 patents, his work has had a considerable impact on the light metal industry.
Latest Patents
Krahenbuhl's latest patents include a "Process for cleaning rolling oils" and a "Process for cleaning rolling lubricant." The first patent addresses the issue of contaminated rolling oils that contain rolling fines from metals processed into semi-finished products, particularly lightweight metals like aluminum. By adding 2 to 8 grams of dimeric oleic acid to every 1000 grams of contaminated oil, the mixture can be passed through a coagulator, allowing the rolling fines to coagulate and be easily removed. The purified oil can then be recirculated as rolling oil. The second patent focuses on cleaning lubrication oils used in rolling strip and foil, which become contaminated with fine metallic particles during the rolling process. This process allows for continuous or batch cleaning by adding a strongly alkaline solution to warm contaminated oil, enabling the coagulation and separation of fine particles through centrifuging or filtering.
