process annealing

การอบเหล็กให้อ่อนตัวตามกรมวิธี คือใช้โลหะผสมมีเหล็กเป็นพื้นฐานเผาให้ร้อนจัดเท่าที่กำหนด แล้วจึงปล่อยให้เย็นลงช้าๆ

Basic Oxygen Furnace (BOF)

(english) "WHAT A pear-shaped furnace, lined with refractory bricks, that refines molten iron from the blast furnace and scrap into steel. Up to 30% of the charge into the BOF can be scrap, with hot metal accounting for the rest. WHY BOFs, which can refine a heat (batch) of steel in less than 45 minutes, replaced open-hearth furnaces in the 1950s; the latter required five to six hours to process the metal. The BOF's rapid operation, lower cost and ease of control give it a distinct advantage over previous methods. HOW Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers. "

Ion exchange

(Environmental Engineering) An adsorption process in which one ion is exchanged for another ion of like charge. There is an equivalence of exchanged charge.

Bath Annealing

(english) Is immersion is a liquid bath (such as molten lead or fused salts) held at an assigned temperature-when a lead bath is used, the process is known as lead annealing.

Paradigms

(Software Engineering) the process model

Agile development (also referred to as agile process model)

(Software Engineering) an adapted version of software engineering that emphasizes customer communication, incremental software delivery, informal methods and work products, and highly motivated teams.

Measurement

(Software Engineering) collecting quantitative data about the software or the software engineering processMetrics

Metabolism

(Environmental Engineering) The processes which sustain an organism, including energy production, synthesis of proteins for repair and replication.

Change of State

(Concrete Engineering) The process whereby liquid is heated to the point of evaporation changing the liquid into a gas the condensation of a gas on a cooler surface returning it from gaseous to liquid form.
