| AFS Tests |
(english) A number of standard tests determined by American Foundrymen's Society to evaluate molding and core sands. |
| Agglomerating Processes |
(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. |
| Aging 1 |
(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. |

| Babbitt |
(english) An antifriction metal alloy used for bearing inserts;made of tin,antimony,lead and copper. |
| Back-up Balance |
(english) Cylinders that supply the force used to hold the back-up rolls up in place. |
| Back-up Roll |
(english) 1) Roll used as a support roll mainly for plater rolls. 2) Two rolls, one on top and one on bottom of the two work rolls which apply pressure and reduce the flexing of the work rolls. |
| Backer (back-up plate) |
(english) A “tool” or reinforcing part, which presses against the outer surface of an extrusion die, supporting it against the pressure of the extruding metal. The backer has an opening larger than the die aperture, allowing the extruded product to emerge without marring its soft surface. |
| BACKUP BOTTLE |
(english) A vessel, normally cylindrical, which is used to store gas for future release of the energy in the compressed gas to an accumulator. |
