Title: Helge J Krogerus: Innovator in Ferroalloy Production
Introduction
Helge J Krogerus is a distinguished inventor hailing from Pori, Finland, with a remarkable portfolio of 11 patents. His contributions to the field of ferroalloy production have positioned him as a significant figure in the materials engineering industry.
Latest Patents
Among his latest innovations, one notable patent describes a "Method for producing manganese containing ferroalloy." This process involves creating an agglomeration mixture that includes chromite ore concentrate and manganese ore fines, all with a grain size smaller than 6-9 mm. The mixture is then agglomerated into green products such as pellets, which are subsequently sintered to produce sintered pellets. These pellets are smelted in a submerged arc furnace, resulting in a ferroalloy that comprises 6.0-35 w-% manganese and 31-54 w-% chromium.
Another significant patent by Krogerus is the "Method for producing ferroalloy containing nickel." This method combines fine-grained raw materials containing iron, chromium, and nickel, forming a mixture with a binding agent. The mixture is agglomerated into objects that are heat-treated for durability before being smelted under reducing conditions to create ferrochrome-nickel, a ferroalloy with a desired composition of iron, chromium, and nickel.
