Title: Innovations of Otto Fischer
Introduction
Otto Fischer is a notable inventor based in Bochum, Germany. He has made significant contributions to the field of metallurgy, particularly in the development of processes and equipment for steel production. With a total of two patents to his name, Fischer's work has had a lasting impact on the industry.
Latest Patents
Fischer's latest patents include an innovative arc furnace roof and a process for producing stainless steels. The arc furnace roof features a central portion formed by a circular group of individually suspended segments. These segments have openings for the passage of arcing electrodes and are designed with cooling water inlets and outlets. This design eliminates the need for thick refractory linings, as the bottoms are only coated with a thin layer of refractory electrical insulation. The electrode openings are insulated to prevent electrode currents from affecting the segments.
The second patent focuses on an improved process for preparing low carbon stainless steel from a higher carbon steel melt containing chromium or chromium nickel. This process utilizes a converter with blast nozzles and lances to supply oxygen and inert gas during different refining phases. The innovation allows for a reduction in the amount of inert gas supplied without significantly increasing refining time, enhancing efficiency in steel production.
