amphitheatre
แปลว่าโรงละครกลางแจ้งมักมีรูปแปลนเป็นวงกลมหรือวงรี
Blue Annealing
แปลว่า(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.
Burning
แปลว่า(english) (1) Permanently damaging a metal or alloy by heating to cause either incipient melting or intergranular oxidation. (2) In grinding getting the work hot enough to cause discoloration or to change the microstructure by tempering or hardening.
low red heat
แปลว่าอุณหภูมิระหว่าง 550 - 700 องศาเซนติเกรด
Box Annealing 2
แปลว่า(english) A process of annealing a ferrous alloy in a closed metal container, with or without packing materials, in order to minimize the effects of oxidation. The charge is normally heated slowly to a temperature below the transformation range, but occasionally above or within it, and then is slowly cooled.
heater confrol
แปลว่าเครื่องปรับลมร้อนช่วย ในขณะเรื่องยนต์ได้รับอากาศเย็นหรือหิมะจับ
Calcine
แปลว่า(Concrete Engineering) To alter composition or physical state by heating to a specific temperature for a specific length of time.
latent heat of air
แปลว่าความร้อนแฝงของอากาศ
Aging 2
แปลว่า(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.
Aging 1
แปลว่า(english) A change in the properties of certain metal and alloys (such as steel) that occurs at ambient or moderately elevated temperatures after a hot working heat treatment or cold working operation. Typical properties impacted are hardness, yield strength, tensile strength, ductility, impact value, formability, magnetic properties, etc. See also Non-aging.
feed water heater
แปลว่าหม้ออุ่นน้ำให้ร้อน ก่อนจะส่งเหม้อน้ำร้อนที่เพิ่มความร้อนทำกำลังไอน้ำ
low-heat portland cement
แปลว่าปูนซีเมนต์ปอร์ตแลนด์ความร้อนต่ำ
