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.

Zinc

แปลว่า(english) Chemical Symbol Zn. Element No. 30 of the periodic system; atomic weight 65.38. Blue-white metal; when pure, malleable and ductile even at ordinary temperatures; melting point 787 (degrees) F.; boiling point 1665 (degrees) F., specific gravity 7.14. Can be electrodeposited; it is extensively used as a coating for steel and sheet zinc finds many outlets, such as dry batteries, etc. Zinc-base alloys are of great importance in die casting. Its most important alloy is brass.

Abrasive 3

แปลว่า(english) A substance capable of grinding away another material.

Bench Work

แปลว่า(english) Work done primarily at a bench with hand tools. Occasionlly suplemented by small power-driven tools.

Agglomerating Processes

แปลว่า(english) "Fine particles of limestone (flux) and iron ore are difficult to handle and transport because of dusting and decomposition, so the powdery material usually is processed into larger pieces. The raw material's properties determine the technique that is used by mills. 1) SINTER Baked particles that stick together in roughly one-inch chunks. Normally used for iron ore dust collected from the blast furnaces. 2) PELLETS Iron ore or limestone particles are rolled into little balls in a balling drum and hardened by heat. 3) BRIQUETTES Small lumps are formed by pressing material together. Hot Iron Briquetting (HBI) is a concentrated iron ore substitute for scrap for use in electric furnaces.

Boss

แปลว่า(english) A projection or an enlarged section of a casting through which a hole may be machine.

Bath

แปลว่า(english) Molten metal on the hearth of a furnace, in a crucible, or in a ladle

Back Gears

แปลว่า(english) Gears fitted to a machine to increase the number of spindle speeds obtainable with a cone or step pulley belt drive.

Bright Dip

แปลว่า(english) An acid solution into which pieces are dipped in order to obtain a clean, bright surface.

BACK PRESSURE

แปลว่า(english) The level of pressure on the return or downstream side of a device or system.

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.

System of Forces:

แปลว่า(english) One or more forces and/or moments acting simultaneously.
