Basic Oxygen Process
แปลว่า(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).
Dissolved oxygen (DO)
แปลว่า(Environmental Engineering) The amount of molecular oxygen dissolved in water.
O
แปลว่า(เคมี) สัญญลักษณของ Oxygen = อ๊อกซิเจ็น
Biochemical oxygen demand (BOD)
แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.
Nitrogenous oxygen demand (NOD)
แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any ammonia present in a water.
Chemical oxygen demand (COD)
แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter in the water using harsh chemical conditions.
Basic Oxygen Furnace (BOF)
แปลว่า(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. "
Basic Oxygen Process 2
แปลว่า(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.
