แปลว่า(กลิ้งหรือพลิก) กลับไปกลับมาเป็นทอดๆ

discharge, average mean monthly

แปลว่าปริมาณน้ำเฉลี่ยรายเดือนของเดือนใดเดือนหนึ่ง โดยได้มาจากค่าเฉลี่ยของปีที่ต่อเนื่องกันหลาย ๆ ปี

Bridle Snubber

แปลว่า(english) The roll above the bridle rolls used to thread the strip. Also is used to steer the strip through the bridle.

Baked Strength

แปลว่า(english) Compressive, shear, tensile or transverse strength of a mold sand mixture when baked at a temperature above 231 B0F (111 B0C) and then cooled to room temperature.

Braze Welding

แปลว่า(english) A family of welding procedures where metals are joined by filler metal that has a melting temperature below the solidus of the parent metal, but above 840 (450 C).

Flocculant settling

แปลว่า(Environmental Engineering) Settling in which particle concentrations are sufficiently high that particle agglomeration occurs. This results in a reduction in the number of particles and an increase in average particle mass. As agglomeration occurs higher settling velocities result.

Normal strain:

แปลว่า(english) Strain measuring the intensity of deformation along an axis. Normal strain is usually denoted by . Average normal strain between two points is calculated as (Delta L / L), where L is the original distance between the points, and L is the change in that distance. Normal strain is often simply called strain.

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.

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.

Bainite

แปลว่า(english) A eutectoid transformation product of ferrite and a fine dispersion of carbide, generally formed at temperatures below 840 to 930 F (450 to 500 C): upper bainite is an aggregate containing parallel lath-shape units of ferrite, produces the so-called feathery appearance in optical microscopy, and is formed at temperatures above about 660 F (350 C); lower bainite consists of individual plate-shape units and is formed at temperatures below about 660 F (350 C). Also, a slender, needle-like (acicular) microstructure appearing in spring steel strip characterized by toughness and greater ductility than tempered Martensite. Bainite is a decomposition product of Austenite best developed at interrupted holding temperatures below those forming fine pearlite and above those giving Martensite.

Brazing

แปลว่า(english) Joining metals by fusion of nonferrous alloys that have melting points above 800 F (425C), but lower than those of the metals being joined. May be accomplished by a torch. Filler metal is ordinarily in rod form in torch brazing; whereas in furnace and dip brazing the work material is first assembled and the filler metal may then be applied as wire, washers, clips, bands, or may be bonded, as in brazing sheet.
