Sand (ASTM C125)

(Concrete Engineering) That portion of an aggregate passing the No. 4 (4.76 mm) sieve and predominantly retained on the No. 200 (74 micron) sieve.

Modulus of elasticity:

(english) The proportional constant between stress and strain for material with linear elastic behavior: calculated as stress divided by strain. Modulus of elasticity can be interpreted as the slope of the stress-strain graph. It is usually denoted as E, sometimes known as Young's Modulus Y, or E-Modulus.

Plasticity

(Concrete Engineering) Property of freshly mixed concrete, cement paste or mortar which determines its ease of molding or resistance to deformation.

By-Pass

(english) Manual control used to by-pass automatic valve if it fails or in an emergency.

Abrasive Wear

(english) The displacement and / or detachment of metallic particles from a surface as a consequence of being exposed to flowing fluids or gases.

Elastic energy:

(english) The energy stored in deformed elastic material (e.g., a watch spring). Elastic energy equals where k is the stiffness, and is the associated deflection. Elastic energy is sometimes called elastic potential energy because it can be recovered when the object returns to its original shape; see potential energy.

Base Metal

(english) (1) The metal present in the largest proportion in an alloy; (2) the metal to be brazed, cut or welded; (3) after welding the part of the metal that was not melted during the process.

Brass

(english) An alloy that is 70% copper,30% zinc. One of the most widely used of the copper-zinc alloys; malleable and ductile; excellent cold-working but poor hot-working and machining properties; excellent for soft-soldering; good for silver alloy brazing or oxyacetylene welding, but fair for resistance or carbon-arc welding. Used for drawn cartridges, tubes, eyelets machine items and snap fasteners.

Basket Screen

(english) A first stage in-line water filter for water delivered from the New Blowing Room Pump Room to the Blast Furnace. The strainer contains an electric-driven rotary sieve that catches particulates and prevents them from entering the water system.

Brasses

(english) Copper base alloys in which zinc is the principal alloying element. Brass is harder and mechanically stronger than either of its alloying elements copper or zinc. It is formable and ductile; develops high tensile strength with cold-working and is not heat treatable.

gasoline engine

เครื่องยนต์ใช้น้ำมันเบนซินเป็นเชื้อเพลิง (อาจเรียกสั้น ๆ gas engine) ก็ได้

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. "
