self-opening die

แปลว่า(กลศาสตร์) แม่พิมพ์กัดเกลียวที่เปิดปล่อยให้วัตถุที่กัดเกลียวหลุดออกได้เอง เมื่อการกัดเกลียวหมดลง

open cut

แปลว่าการขุดดินแบบเปิดจากผิว

open mold

แปลว่า(โรงหล่อ) แม่พิมพ์เปิด, ใช้ในการหล่อวัตถุแท่ง, แผ่น, โดยไม่ใช้หีบหล่อ หากใช้ทรายปูระดับราบแล้วกดแม่พิมพ์ลงไป เมื่อยกแม่พิมพ์ออก จึงเทโลหะที่หลอมละลายลง

Gillmore Needle

แปลว่า(Concrete Engineering) A device used in determining time of setting of hydraulic cement, described in ASTM 0 266. Gradation The sizing of granular materials; for concrete materials, usually expressed in terms of cumulative percentages larger or smaller than each of a series of sieve openings or the percentages between certain ranges of sieve openings.

Ottawa Sand

แปลว่า(Concrete Engineering) A sand used as a standard in testing hydraulic cements by means of mortar test specimens. Sand is produced by processing silica rock particles obtained by hydraulic mining of the orthoquartzite situated in open-pit deposits near Ottawa, Illinois; naturally rounded grains of nearly pure quartz.

Backer (back-up plate)

แปลว่า(english) A “tool” or reinforcing part, which presses against the outer surface of an extrusion die, supporting it against the pressure of the extruding metal. The backer has an opening larger than the die aperture, allowing the extruded product to emerge without marring its soft surface.

open washer

แปลว่าวงแหวนรองแป้นเกลียวชนิดเปิดข้าง

Hydrologic Cycle

แปลว่า(Concrete Engineering) The Hydrologic Cycle consists of the evaporation of water from oceans and other bodies of open water; condensation to produce cloud formations; precipitation of rain, snow, sleet or hail upon land surfaces; dissipation of rain or melted solids by direct run-off into lakes and by seepage into the soil. Thereby producing a continuing endless source of water in the sub-grade.

opening

แปลว่ารู, ช่องเปิด

open end wrench

แปลว่ากุญแจปากตาย

Acid Process 1

แปลว่า(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 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. "
