Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz-Donawitz steelmaking or the oxygen converter process, [1] is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel.

Basic Oxygen Furnace (BOF) steel making or Basic Oxygen Furnace Steelmaking (BOS) or Linz-Donawitz-Verfahren steelmaking or the oxygen converter process is a method in which both molten pig iron and steel scrap are converted into steel with the oxidizing action of oxygen blown into the melt under a basic slag.

Apr 15, 2025 · Steel - Basic Oxygen, Refining, Alloying: 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.

Mar 2, 2015 · Steel making operation in the basic oxygen furnace (BOF) is also sometimes called basic oxygen steel making (BOS). This is the most powerful and effective steel making technology in the world. Around 71 % of the crude steel is made by this process.

Dec 8, 2013 · Basic oxygen steelmaking (BOS) is the most widely used primary steelmaking process for the production of crude steel from hot metal (HM). The process vessel is known as converter. It plays a predominant role in integrated steel plants for the production of crude steel.

Jan 27, 2010 · The purpose of the Basic Oxygen Steelmaking (BOS) process is to refine the hot metal produced in the blast furnace into raw liquid steel, which may be subsequently refined in the secondary steelmaking shop.

May 14, 2011 · Accounting for 60% of the world’s total output of crude steel, the Basic Oxygen Steelmaking (BOS) process is the dominant steelmaking technology. In the U.S., that figure is 54% and slowly declining due primarily to the advent of …

What is Air-cooled basic oxygen steel slag (BOS)? Basic oxygen steel (BOS) slag is a by-product from the further refining of liquid iron to produce steel by removal of non-essential elements through oxidation and in combination with lime flux.

BOS (Basic Oxygen Steelmaking) plant. Molten iron from the blast furnace is transported in specialized refractory brick lined ‘torpedoes’ on rail cars (varying in capacity from 200-450 tonnes) to the BOS plant where the iron is refined to produce steel of desired quality and composition.

Dec 16, 2015 · Basic oxygen steelmaking (BOS) is the process of making steel by blowing pure oxygen (O2) in a liquid metal bath contained in a vessel which is known as basic oxygen furnace (BOF), LD converter, or simply converter.
