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.

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.

Brake

แปลว่า(english) A piece of equipment used for bending sheet; also called a bar folder. If operated manually, it is called a hand brake; if power driven, it is called a press brake.

Butt end

แปลว่า(english) The residual portion of an extrusion billet that is not forced through the die at the end of the extrusion cycle.

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.

Blind Bole

แปลว่า(english) A hole made in a workpiece that does not pass through it.

Base Type

แปลว่า(english) Tin Mill term; Thickness divided by .00011. Also weight in pounds of one Base Box of Tin plate. In finished inventory base weight is specified instead of decimal thickness.

Load:

แปลว่า(english) An external force. The term load is sometimes used to describe more general actions such as temperature differentials or movements such as foundation settlements.

Base

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

Reaction:

แปลว่า(english) A reaction is a force exerted by a support on an object: sometimes called support reaction. Using this definition, a reaction is an external force.

Busheling

แปลว่า(english) A widely traded form of steel scrap consisting of sheet clips and stampings from metal production. Bushel baskets were used to collect the material through World War II, giving rise to the term.

Blast Furnace

แปลว่า(english) 1) A furnace in which solid fuel (limestone, coke, iron ore) is combined with high-pressure, hot air blast (120,000 psi) to smelt ore in a continuous process (They are never stopped. They can be slowed down or idled). A Blast Furnace in the iron and steel industry is used to produce liquid iron.
