raudreduksiooni

Raudreduktsioon refers to the process of reducing iron oxides to metallic iron. This is a fundamental metallurgical process with significant historical and industrial importance. The most common method historically, and still widely used, is the blast furnace. In a blast furnace, iron ore, coke (a form of carbon), and flux (like limestone) are heated to very high temperatures. The carbon acts as a reducing agent, chemically removing oxygen from the iron oxides, thereby producing molten iron. Other reduction methods exist, such as direct reduced iron (DRI) processes, which bypass the blast furnace stage and produce iron in a solid state. These methods often involve using natural gas or coal to reduce the iron ore at lower temperatures than a blast furnace. Raudreduktsioon is crucial for the production of steel, as iron is the primary component of steel alloys. The efficiency and economics of raudreduktsioon have been continuously improved over centuries, driven by the demand for iron and steel in construction, manufacturing, and transportation.
