Title: Innovations of Heinz Wilhelm Berger
Introduction
Heinz Wilhelm Berger is a notable inventor based in Mulheim (Ruhr), Germany. He has made significant contributions to the field of metal processing, particularly in the production of cold-rolled strips. With a total of 3 patents to his name, Berger's work showcases his expertise and innovative spirit.
Latest Patents
One of Berger's latest patents is a method of producing a cold-rolled strip in one pass. This method involves several steps, including unwinding a coil of strip, mechanically descaling it if necessary, and then subjecting it to chemical and/or electrochemical pickling. The process continues with cold-rolling the strip to finished dimensions, followed by degreasing, annealing, finish-pickling, and, if needed, passivating, dressing, and stretcher-leveling the strip. The pickling step utilizes a solution containing hydrochloric acid, sulfuric acid, and/or nitric acid.
Another significant patent is for a strip pickling apparatus designed for straight-through strip travel. This apparatus features feed means with bridle-roller pairs that longitudinally displace the strip under tension along a straight transport path. The housing of the apparatus is divided into compartments, each containing a treatment bath, typically of acid. The design ensures that liquid from one bath does not pass into the next compartment, maintaining the integrity of the treatment process.
