Title: Wilfried Pulvermacher: Innovator in Steel Production Technology
Introduction
Wilfried Pulvermacher is a notable inventor based in Bochum, Germany. He has made significant contributions to the field of steel production, particularly through his innovative patents. With a total of two patents to his name, Pulvermacher has demonstrated a commitment to advancing technology in the industry.
Latest Patents
Pulvermacher's latest patents include an 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 sides that cooperatively form openings for the passage of arcing electrodes. Each segment is designed with a metal shell that includes cooling water inlets and outlets, along with internal baffles to ensure adequate cooling. 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 isolate the segments from electrode currents.
The second patent, a process for producing stainless steels, improves the preparation of low carbon content 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.
