Title: Bernt Rollinger: Inventor in Stainless-Steel and Molten-Steel Production
Introduction
Bernt Rollinger is an inventor associated with Taunusstein, Germany. His work focuses on steelmaking processes, including stainless-steel production and methods for producing refined molten steel. He is credited with 2 patents.
Latest Patents
Rollinger’s listed patents address two approaches to improving steel production.
- **Method for Producing Stainless Steels, in Particular High-Grade Steels Containing Chromium and Chromium-Nickel.** This invention describes alternating electric-arc furnace treatment and air refining in a steelmaking process. It aims to improve efficiency by reversibly treating unreduced, chromium-rich converter slag. During the electric-arc stage, the slag is melted with the charge and reduced using silicon and carbon under favorable conditions. The process then proceeds to air refining, where the carbon content is reduced, while chromium-rich slag remains in the treatment vessel.
- **Process and Apparatus for Making Molten Steel.** This patent describes melting preheated solid iron and carbon sources using electric-arc heat, followed by further melting through combustion reactions. Oxygen is introduced below the surface of the molten bath through nozzles. The process also uses exhaust gases to preheat solid iron sources and then burns them in an afterburner to reduce pollution.
