Burn-Out

แปลว่า(english) Firing a mold at a high temperature to remove pattern material residue.

Belt Wrapper

แปลว่า(english) Line equipment used in the Tin Mill for starting coils on prime or reject reels. The belt wrapper ensures a proper start.

Bentonite

แปลว่า(english) A colloidal clay derived from volcanic ash and employed as a binder in connection with synthetic sands, or added to ordinary natural (clay-bonded) sands where extra strength is required.

Bull Gear

แปลว่า(english) The large crank gear of a shaper.

Blow Back

แปลว่า(english) A coating defect consisting of a lower coating film weight on the bottom of the coated sheet caused by high velocity air in the oven. Blow back usually occurs with high solids coatings which have little solvent to evaporate and "set" the film.

Stiffness:

แปลว่า(english) This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement. High stiffness means that a large force produces a small displacement. When discussing the stiffness of a material, the concept is the same, except that stress substitutes for force, and strain substitutes for displacement; see modulus of elasticity.

Brasses

แปลว่า(english) Copper base alloys in which zinc is the principal alloying element. Brass is harder and mechanically stronger than either of its alloying elements copper or zinc. It is formable and ductile; develops high tensile strength with cold-working and is not heat treatable.

Bed-In

แปลว่า(english) Method whereby drag may be rammed in the pit or flask without necessity of rolling over. Process used in production of heavy castings.

Acme Thread

แปลว่า(english) A screw thread having a 29 degree included angel. Used largely for feed and adjusting screws on machine tools.

Basic Oxygen Furnace (BOF)

แปลว่า(english) "WHAT A pear-shaped furnace, lined with refractory bricks, that refines molten iron from the blast furnace and scrap into steel. Up to 30% of the charge into the BOF can be scrap, with hot metal accounting for the rest. WHY BOFs, which can refine a heat (batch) of steel in less than 45 minutes, replaced open-hearth furnaces in the 1950s; the latter required five to six hours to process the metal. The BOF's rapid operation, lower cost and ease of control give it a distinct advantage over previous methods. HOW Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers. "

Banded Structure

แปลว่า(english) Appearance of a metal showing parallel bands in the direction of rolling or working

Body force:

แปลว่า(english) An external force acting throughout the mass of a body. Gravity is a body force. An inertial force is a body force.
