Title: Siegfried Zeller: Innovator in Steel Production Technology
Introduction
Siegfried Zeller is a notable inventor based in Linz, Austria. He has made significant contributions to the field of steel production, holding a total of 2 patents that focus on improving efficiency and reducing energy consumption in integrated steel mills.
Latest Patents
Zeller's latest patents include a mill arrangement with primary gas mixing means. This invention describes a mill for the production of steel from both liquid and solid charging substances. It incorporates a coking plant, a blast furnace plant, a converter steelworks, and a plant for the direct reduction of iron ore. The converter steelworks is charged with molten pig iron from the blast furnace, scrap, and sponge iron from the direct reduction plant. The reduction gas is composed of converter offgas, top gas, and blast furnace gas. To avoid coal deposits in the direct reduction plant and improve the composition of the reduction gas, the coke oven gas component undergoes fractionation by alternating pressure adsorption, increasing its hydrogen content while lowering hydrocarbons.
Another significant patent is the integrated steel mill arrangement. This invention addresses the large amounts of partially high-grade cupola gases, such as coke oven gas and converter exhaust gases, produced during the operation of mills. To enhance the efficiency of utilizing these gases and reduce specific energy consumption per ton of crude steel produced, a plant for directly reducing iron ore is added to the mill. The exhaust gas ducts from the converters and the coke oven gas ducts from the coking plant are connected to a reformer, which produces reducing gas primarily containing CO and H. This reformer is linked to the direct reduction plant via a reducing gas duct.
