Steelmaking and Refining | Introduction to Chemistry

Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron (the iron created in the blast furnace) is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.

Steps in the Modern Steelmaking Process

At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5 percent. EAF methods, however, feed recycled steel scrap through use high-power electric arcs (temperatures up to 1650 C) to melt the metal and convert it into high-quality steel.

AOD production (Argon-Oxygen-Decarburization) In this process the merger is implemented in conventional furnace. Subsequently, the liquid passes to the converter, within which the steel undergoes the refining chemical analysis through redox reactions. Blowing argon and oxygen, using sheets, maintain a continuous mixing.

Steel - Basic oxygen steelmaking | Britannica

Steel - Steel - Basic oxygen steelmaking: More than half the world's steel is produced in the basic oxygen process (BOP), which uses pure oxygen to convert a charge of liquid blast-furnace iron and scrap into steel. The basic oxygen furnace (BOF) is a refractory-lined, tiltable converter into which a vertically movable, water-cooled lance is inserted to blow oxygen through nozzles at ...
