Primitive Skills; Making Steel From Iron Ore - primitiveskills
So the process of distributing the ore into the furnace is also very important. The above stage is based on the metallurgical principle: When iron ore, coal is arranged in layers. The hot air blows from the bottom to meet coal (C) and burns carbon dioxide or carbon dioxide (CO2): C + O2 (temperature) -> CO2 (gas); continue to burn and form Carbon Monoxide: C + CO2 (temperature) -> 2CO; Thanks to the carbon monoxide reducing ironIron ore - Wikipedia,Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are knownThe Modern Steel Manufacturing Process - ThoughtCo,21/08/2020· Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.
