Blacking Hole

แปลว่า(english) Irregular-shaped surface cavities in a casting containing carbonaceous matter. Caused by spilling off of the blacking from the mold surface.

battery container

แปลว่า(ไฟฟ้า) เปลือกหม้อแบตเตอรี่, ลักษณะเป็นยางแข็ง หรือส่วนประกอบพลาสติกหล่อเป็นรูปหม้อแบตเตอรี่ตามความต้องการ

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. "

Cement Content

แปลว่า(Concrete Engineering) A quantity of cement contained in a unit volume of concrete or mortar, ordinarily expressed as pounds, barrels, or bags per cubic yard.

Mass Curing

แปลว่า(Concrete Engineering) Adiabatic curing, using sealed containers.

Water Vapor Pressure

แปลว่า(Concrete Engineering) The pressure exerted by water vapor. Air that contains higher amounts of water vapor exerts a higher vapor pressure than air which has a lower amount of has a higher water vapor pressure In concrete water vapor pressure is calculated by the difference between the vapor pressure of the concrete and the ambient relative humidity and temperature and in contact with the soil. that is calculated by; based upon relative humidity and temperature. The greater the difference between the water vapor and ambient humidity and temperature, in degrees Fahrenheit. the greater the water vapor pressure exerted.

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.

Acid Steel

แปลว่า(english) Steel melted in a furnace with an acid bottom and lining and under a slag containing an excess of an acid substance such as silica.

Bronze

แปลว่า(english) An alloy containing 90% copper and 10% tin. Used for screws, wire, hardware, wear plates, bushings and springs; it is somewhat stronger than copper and brass and has equal or better ductility.

Organic compound

แปลว่า(Environmental Engineering) Any compound containing carbon except for the carbonates (carbon dioxide, the carbonates and bicarbonates), the cyanides, and cyanates.

Billet container

แปลว่า(english) The part of the extrusion press into which the billet to be extruded is placed.

Bessemer Process

แปลว่า(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.
