Basic Oxygen Process

(english) (BOP) A process in which molten steel is produced in a furnace by blowing oxygen into molten iron, scrap and flux materials. The furnace is known as Basic Oxygen Furnace (BOF).

Process framework

(Software Engineering) a relatively small set of fundamental software engineering activities that define a software process

Aerobic process

(Environmental Engineering) A process which requires molecular oxygen.

Acid Process 1

(english) A process of making steel, either Bessemer, open-hearth or electric, in which the furnace is lined with a siliceous refractory and for which low phosphorus pig iron is required as this element is not removed.

Basic Oxygen Process 2

(english) A steel making process wherein oxygen of the highest purity is blown onto the surface of a bath of molten iron contained in a basic lined and ladle shaped vessel. The melting cycle duration is extremely short with quality comparable to Open Hearth Steel.

Agglomerating Processes

(english) "Fine particles of limestone (flux) and iron ore are difficult to handle and transport because of dusting and decomposition, so the powdery material usually is processed into larger pieces. The raw material's properties determine the technique that is used by mills. 1) SINTER Baked particles that stick together in roughly one-inch chunks. Normally used for iron ore dust collected from the blast furnaces. 2) PELLETS Iron ore or limestone particles are rolled into little balls in a balling drum and hardened by heat. 3) BRIQUETTES Small lumps are formed by pressing material together. Hot Iron Briquetting (HBI) is a concentrated iron ore substitute for scrap for use in electric furnaces.

Adeline Steelmaking Process

(english) Method of producing a precision casting of steel or steel alloys using aluminolthermic process and lost wax, followed by centrifugal action.

Bessemer Process

(english) A process for making steel by blowing air through molten pig iron contained in a refractory lined vessel so that the impurities are thus removed by oxidation.

Anaerobic process

(Environmental Engineering) A process which only occurs in the absence of molecular oxygen.

Acid-Process

Anoxic process

(Environmental Engineering) A process which occurs only at very low levels of molecular oxygen or in the absence of molecular oxygen.

Unified process

(Software Engineering) a "use-case driven, architecture-centric, iterative and incremental" software process that emphasizes the use of UML notation
