Jan 14, 2019· Hydrogen gas as reductant of iron ore. The reduction of iron ore by hydrogen in combination with carbon mono oxide is being practiced during iron production by injection of hydrogen rich gases like natural gas, and coke oven gas, or materials like waste plastics in the blast furnace or during the production of direct reduced iron with natural gas.

reduction reaction to convert iron ore into crude steel. The reduction reaction occurs between carbon monoxide and iron oxide (the form of ferrous metal in iron ore), which converts to iron and carbon dioxide [8]. The creation of carbon monoxide is a result of .

Iron orebased steelmaking accounts for about 70% of world steel production. Iron ore is reduced to iron and then converted to steel. The main inputs are iron ore, coal, limestone and recycled (scrap) steel. The main orebased production routes are: ironmaking via the blast furnace (BF) followed by steelmaking in the basic oxygen

The solid density of iron ore generally lies between and tonnes per cubic metre, depending on the particular characteristics of the ore being considered.

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
