Latest Patents

Wetzel holds a patent for a method of producing steel from fine-grained iron ores. This method involves preheating and partially reducing the fine-grained iron ores in a countercurrent heat exchanger. The preheated and partially reduced ores are then reduced in a fluidized bed reactor to form sponge iron. The process utilizes exhaust gases, primarily carbon monoxide, from a melting vessel where sponge iron is melted. The fine-grained sponge iron produced is separated from the reduction gases and pneumatically transported into a carbon-containing melt in the melting vessel. The sponge iron is then melted and subjected to final reduction with carbon in the metal melt, along with additional carbonaceous material. The melt is refined using pure oxygen, which is introduced through nozzles positioned below the surface of the metal melt.
