How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ...

Basic Oxygen Furnace (BOF) steelmaking is, worldwide, the most frequently applied process. According to the world steel organization statistical report, 2021, it saw a total production share of 73.2%, or 1371.2 million tons per year of the world steel production in 2020. The rest is produced in Electric Arc Furnace (EAF)-based steel mills (26.3%), …

STEELMAKING OROBM (Q-BOP) PROCESS. The successful development and application of the shrouded oxygen tuyere in the late 1960s led to the development of the OBM (Q-BOP) process in the early 1970s. Oxygen in this process is injected into the bath through tuyeres inserted in the bottom of the furnace.

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. The basic oxygen furnace (BOF) is a refractory-lined, tiltable converter into which a vertically movable, water-cooled lance is inserted to blow …

stock materials goes beyond their cost. How a material's characteristics affect steel manufacturing cost is its Value-in-Use (VIU). This consists of the material's contribution of Fe to the steel bath and the impact of residual metallic impuri-ties and also recognition that all of the non-metallic components impact the steelmaking process.

A large fraction of production of stainless steels is produced to a maximum carbon content of 0.07 % or 0.08 %. The stainless steel gets its stainless characteristics through the formation of an invisible and adherent chromium-rich oxide film. This oxide film forms and heals itself in the presence of oxygen.
