Bedding a Core

แปลว่า(english) Resting an irregularly shaped core on a bed of sand for drying.

Strain:

แปลว่า(english) The intensity of deformation at a point in an object. See normal strain and shear strain.

Zirconium

แปลว่า(english) Silvery-white, metallic element, mp 1860 B0C (3380 B0F), a powerful deoxidizer when added to molten steel.

Brittle Fracture 2

แปลว่า(english) Fracture preceded by little or negligible plastic deformation.

Fixed support:

แปลว่า(english) In two dimensions, a fixed support restrains three degrees of freedom: two translations and one rotation.

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.

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.

Base

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