WebMar 17, 2024 · Blast Furnace Route . Large European blast furnaces can produce around four million tonnes of iron per year. They rely on a chemical process called reduction: Iron ore is an iron oxide and to separate iron from oxygen carbon is needed as a so-called reducing agent. In the process it combines with the oxygen and forms carbon dioxide. … WebBefore iron ore can be used, oxygen must be removed from it. Known as ‘reducing’, this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process …
WebApr 11, 2024 · The real-time data of blast furnace gas (BFG) generation collected in iron and steel sites are also of low quality. In order to tackle this problem, a three-stage data quality improvement strategy was proposed to predict the BFG generation. In the first stage, correlation principle was used to test the sample set.
