2020/7/22· The oxygen steelmaking process rapidly refines a charge of molten pig iron and aient scrap into steel of a desired carbon and temperature using high purity oxygen. Steel is made in discrete batches called heats. The furnace or converter is a barrel shaped, open topped, refractory lined vessel that can rotate on a horizontal trunnion axis. The basic operational steps of the process (BOF) are

Process annealing is also called as subcritical annealing or in-process annealing. This process is often referred as intermediate annealing. For process annealing, we require the temperature in the range of 260 º to 760º C. In process annealing, the metal is It is
Direct reduced iron - Wikipedia
Process Direct reduction processes can be divided roughly into two egories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 C (2,190 F)).
Introduction and secondary refining - Iron and …
In this lesson, we''ll discuss about new steel making, in which is called secondary refining. Which steel produced from furnace, but delie steel is further cleaned and be transformed into a molten form for the next process, casting. And also in this lesson, we
What is the Structural Steel Fabriion Process?
Structural steel fabriion is a multifaceted process that requires specialized knowledge, skills, and resources to complete successfully.To create structural steel beams, components, or equipment, a good metal fabrior follows a specific process: Step 1: Ideation
How iron is made - material, manufacture, making, …
The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted
Glossary of Metal Industry Terms - Reade
Alloys change the properties of the steel making it, for example, harder, more formable, etc., depending on the coination and amounts of alloys used. Annealing: The process by which steel is heated and then cooled to improve its formability and make its surface more durable.

Overview of heat treatment processes - tec-science
Such a stretched microstructure is then also called a rolling texture. The rolled steel sheet behaves differently in a subsequent bending process in the rolling direction than tranverse to it. While the steel tends to crack when bent parallel to the rolling direction, the risk of cracking is considerably lower when bent transversely to the rolling direction.
