A breakthrough in iron smelting technology, announced by Chinese scientists, could revolutionize the steel industry. The new ironmaking method, dubbed Flash Ironmaking Technology, can produce liquid iron in just three to six seconds. In comparison, traditional blast furnaces take about five to six hours to complete the process. The efficiency of the new technology is 3,600 times greater, an exceptional leap in productivity.
How does the new technology work?
The method involves injecting finely ground iron ore powder into a superheated furnace, which initiates an explosive chemical reaction. The resulting droplets of liquid iron can be used directly to produce steel. A key element of the innovation is a specially designed injection nozzle that efficiently disperses the ore into the reaction space. One reactor, equipped with three such nozzles, can produce more than 7 million tons of iron per year.
Environmental and economic benefits
The technology has the potential to significantly reduce carbon emissions by eliminating the need for coal-based coke. In China, where traditional steelmaking accounts for a significant portion of industrial emissions, the new method can contribute to ambitious climate goals and reduce reliance on high-quality ore imports.
The future of the steel industry
The technology took more than a decade to develop, and its practical implementation was preceded by intensive laboratory research and pilot testing. The global application of the new method could revolutionize production processes in the steel industry, making them more sustainable and economical.
The new technology opens the door to more efficient and environmentally friendly steel production, which could change the way this key industrial sector operates around the world.
