Title: Wilhelm Nickel: Innovator in Steel Hardening and Seamless Pipe Manufacturing
Introduction
Wilhelm Nickel is a prominent inventor based in Muelheim, Germany. He has made significant contributions to the field of metallurgy, particularly in the hardening of cylindrical hollow objects and the manufacturing of seamless pipes. With a total of 5 patents to his name, Nickel's work has had a lasting impact on the industry.
Latest Patents
One of Nickel's latest patents focuses on a method for hardening cylindrical hollows made of steel. This innovative technique involves heating followed by cooling, utilizing a water bath while the hollow rotates about its longitudinal axis. The method is enhanced by a specific rotation of the hollow as long as its temperature remains above the martensitic starting temperature. Additionally, the speed of rotation is drastically increased as the martensitic transition temperature is reached, resulting in improved hardening efficiency.
Another notable patent involves the production of seamless pipes with diameters exceeding 200 mm. This method utilizes solid rounds with a diameter not exceeding 0.8 of the final tubing or pipe diameter. The process includes piercing the solid with a mandrel, followed by a smoothing step, and a widening of the pierced hollow under reduced wall thickness. This innovative approach allows for the efficient manufacturing of large seamless pipes.
