Title: Burkhart Schifferings: Innovator in Seamless Pipe Rolling Technology

Introduction

Burkhart Schifferings is a notable inventor based in Duisburg, Germany. He has made significant contributions to the field of manufacturing, particularly in the rolling of seamless pipes. His innovative methods have paved the way for advancements in industrial processes.

Latest Patents

Schifferings holds a patent for a "Method of longitudinal rolling of seamless pipe." This invention describes a continuous rolling procedure on an internal tool within a multiple-stand rolling train. The method involves a unique approach where the rolls of successive rolling stands are mounted offset relative to each other. In the first of two rolling passes, a roll thickness reduction is achieved with opened roll groove sides, which corresponds to or slightly exceeds the roll thickness of the finished pipe. The second rolling pass further reduces the side portion of the first pass to the wall thickness of the finished pipe. By applying a controlled tensile force on the pipe between the two passes, the increase in circumference due to spreading is minimized, allowing for efficient production without significant wall thickness reduction.
