Abstract. The physical–chemical blast furnace model first built by Michard and Rist has proven to be a very efficient tool to predict and drive the present blast furnaces. It mostly describes the iron blast furnace as a counter current gas-solids dual heat and oxygen exchanger. The onset of coke gasification (orelse of iron oxide direct ...

The composition of the COREX export gas with the ratio H 2/CO = 0.3–0.5 is as follows (%): CO 43–45; H 2 12–22; CO 2 30–32; N 2 1–6; H 2O 1–6; CH 4 1–2. The HYL technologyemploys steam conversion of natural gas (NG), so the reducing gas contains roughly 80% H 2. In contrast to the classical HYLIII technology, its later modification – the ZR technology – does use a …

Limestone, coke and iron ore are added at the top. Hot air is blasted in front rom the bottom. The hot air burns the coke and makes carbon dioxide. Carbon dioxide reacts with more coke to form carbon monoxide. Carbon monoxide reacts with iron oxide and forms molten iron and carbon dioxide. The molten iron sinks to the bottom.

The document describes the process of forming iron and steel using a blast furnace. It involves the following key steps: 1. Sinter is added to the top of the blast furnace. Air is blasted into the bottom to fuel reactions that melt the iron out of the sinter. 2. Molten iron collects at the bottom of the furnace and is tapped out periodically.

Most of the iron produced in the blast furnace is usually turned into steel. The diagram below shows the main parts of the blast furnace with a brief description of what they do. Iron ore, mostly haematite (Fe 2 O 3) is mixed with coke and limestone and dropped into the top of the blast furnace on a regular basis.
