Title: The Innovations of Lars-Gunnar Norberg
Introduction
Lars-Gunnar Norberg is a notable inventor based in Hagfors, Sweden. He has made significant contributions to the field of metallurgy, holding a total of six patents. His work focuses on processes that enhance the production of ferro alloys and improve metallurgical furnace designs.
Latest Patents
One of Norberg's latest patents is a process for the production of ferro alloys. This innovative process involves adding a reducing agent with an excess of silicon or aluminum to a converter containing a previous product melt and a slag rich in oxides of chromium or manganese. The method includes injecting fluid into the melt to create intensive agitation, which facilitates the reduction of oxides in the slag. Additionally, lime is introduced to fix the resulting silicic acid or aluminum oxide, allowing for the removal of slag with reduced chromium or manganese content. Another significant patent involves a metallurgical furnace equipped with fluid injection means for a melt. This design allows for the injection of reactive materials into the melt while addressing the rapid erosion of the vessel's wall, which is designed for easy repair or replacement.
