Box Annealing

แปลว่า(english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing.

Black Annealing

แปลว่า(english) A process of box annealing or pot annealing ferrous alloy sheet, strip or wire after hot working and pickling.

Bright Annealing 2

แปลว่า(english) The process of annealing in a protective atmosphere so as to prevent discoloration of the bright surface desired.

Bath Annealing

แปลว่า(english) Is immersion is a liquid bath (such as molten lead or fused salts) held at an assigned temperature-when a lead bath is used, the process is known as lead annealing.

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.

Brown Sharp Gages

แปลว่า(english) A standard series of sizes refered to by numbers, in which the diameter of wire or thickness of sheet metal is generally produced and which is used in the manufacture of brass, bronze, copper, copper-base alloys and aluminum. These gage numbers have a definite relationship to each other. In this system, the decimal thickness is reduced by 50% every six gage numbers- while temper is expressed by the number of B&S gage numbers as cold reduced in thickness from previous annealing. For each B&S gage number in thickness reduction, where is assigned a hardness value of 1/4 hard.

Bright Bessemer Wire

แปลว่า(english) Stiff bright wire of hard temper. Normally wire is drawn down to size without annealing.

process annealing

แปลว่าการอบเหล็กให้อ่อนตัวตามกรมวิธี คือใช้โลหะผสมมีเหล็กเป็นพื้นฐานเผาให้ร้อนจัดเท่าที่กำหนด แล้วจึงปล่อยให้เย็นลงช้าๆ

Bright Annealing

แปลว่า(english) A process carried out usually in a controlled furnace atmosphere, so surface does not oxidize, remaining bright.

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.

annealing

แปลว่า(โลหะ) การเผาโดยให้ความร้อนขึ้นทีละน้อย ๆ แล้วปล่อยให้เย็นลงช้า เพื่อให้วัตถุที่เป็นแก้ว โลหะ หรือวัตถุใด ๆ ลดความแข็งเปราะลง ช่วยให้ดัดงอหรือโค้งได้โดยไม่เสียหาย

Base

แปลว่า(english) The steel or concrete pedestal on which the coils are stacked during the batch annealing process.
