Basic oxygen steelmaking is a primary steelmaking process for converting molten pig iron into steel by blowing oxygen through a lance over the molten pig iron inside the converter. Exothermic heat is generated by the oxidation reactions during blowing. The basic oxygen steel-making process is as follows:
To reduce the carbon content in pig iron and obtain the desired carbon content of steel, it is re-melted and oxygen is blown through in basic oxygen steelmaking. In this step, the oxygen binds with the undesired carbon, carrying it away in the form of CO 2 gas, an additional emission source. After this step, the carbon content in the pig iron ...
Open-hearth steelmaking had superseded the Bessemer process in UK by 1900, but elsewhere in Europe, especially in Germany, the Bessemer and Thomas processes were used until the late 1960s when they were superseded by basic oxygen steelmaking. The last open-hearth furnace in former East Germany was stopped in 1993. In the US, steel production ...
It was eventually superseded by basic oxygen steelmaking. In the U.S., commercial steel production using this method stopped in 1968. It was replaced by processes such as the basic oxygen (Linz–Donawitz) process, which offered better control of final chemistry. The Bessemer process was so fast (10–20 minutes for a heat) that it allowed ...
Oxygen blowing is a method of steelmaking where oxygen is blown through pig iron to lower the carbon content. Oxygen forms oxides with the unwanted elements, such as carbon , silicon , phosphorus , and manganese , which appear from various stages of the manufacturing process.
The casting houses, dust catcher and charge conveyors also came down on Wednesday, following a similarly spectacular demolition of the 213ft (65m) tall Basic Oxygen Steelmaking plant in October.
Refining of a 9.5%CrMoWVNbN steel in an argon, oxygen decarburisation (AOD) vessel. Argonoxygen decarburization (AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminium.
