| Bazooka | (english) Performs functions of Galvanneal Furnace; set of torches on wheels used to shoot flames onto a strip to further heat it. |
| Bearing Strength | (english) The maximum bearing load at failure divided by the effective bearing area. In a pinned or riveted joint, the iffective area is calculated as the product of the diameter of the hole and the thickness of the bearing member. |
| Bending Angle | (english) A 'V-shaped' piece of angle iron attached to the rear of the coil car in the Strip Steel, which is used to help the operator put bends into the front end of a coil. |
| Bending Strength | (english) Upper limit of normal stress of a beam at which fracture or excessive plastic deformation occurs. |
| Bentonite | (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. |
| BETA RATIO (#) | (english) The amount, expressed as a ratio, of particles in a fluid stream upstream of a filter, after the fluid posses through a filter, divided by the amount of particles downstream, for a particular size particle. |
| Black Annealing | (english) A process of box annealing or pot annealing ferrous alloy sheet, strip or wire after hot working and pickling. |
| Black Oil Tempered Spring Steel Strip (Scaleless Blue) | (english) A flat cold rolled usually .70/.80 medium high carbon steel strip, blue-black in color, which has been quenched in oil and drawn to desired hardness. While it looks and acts much like blue tempered spring steel and carries a Rockwell hardness of C44/47, it has not been polished and is lower in carbon content. Used for less exacting requirements than clock spring steel, such as snaps, lock springs, hold down springs, trap springs, etc. It will take a more severe bend before fracture than will clock spring, but it does not have the same degree of spring-back. |
| Black Plate | (english) A light weight or a thin uncoated steel sheet or strip so called because of its dark oxide coloring prior to pickling. It is manufactured by two different processes. (1) Form sheet bar on single stand sheet mills or sheet mills in tandem. This method is now almost obsolete. (2) On modern, high speed continuous tandem cold reduction mills from coiled hot rolled pickled wide strip into ribbon wound coils to finished gage. Sizes range from 12 to 32 in width, and in thicknesses from 55 lbs. to 275 lbs. base box weight. It is used either as is for stampings, or may be enameled or painted or tin or terne coated. |
| Blast Furnace | (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. |
