| Basic Oxygen Process 2 | (english) A steel making process wherein oxygen of the highest purity is blown onto the surface of a bath of molten iron contained in a basic lined and ladle shaped vessel. The melting cycle duration is extremely short with quality comparable to Open Hearth Steel. |
| Basket Screen | (english) A first stage in-line water filter for water delivered from the New Blowing Room Pump Room to the Blast Furnace. The strainer contains an electric-driven rotary sieve that catches particulates and prevents them from entering the water system. |
| Bearing Load | (english) A compressive load supported by a member, usually a tube or collar, along a line where contact is made with a pin, rivet, axle, or shaft. |
| Belly Roll | (english) Roll used on the line to steady plate. |
| Belt Wrapper | (english) Line equipment used in the Tin Mill for starting coils on prime or reject reels. The belt wrapper ensures a proper start. |
| Bend Test | (english) Various tests which is used to ascertain the toughness and ductility of a metal product, in which the material is bent around its axis and/ or around an outside radius. A complete test might specify such a bend to be both with and against the direction of grain. For testing, samples should be edge filed to remove burrs and any edgewise cracks resulting from slitting or shearing. If a vice is to be employed, then you must line the jaws with some soft metal, to permit a flow of the metal in the piece being tested. |
| Bessemer Process | (english) A process for making steel by blowing air through molten pig iron contained in a refractory lined vessel so that the impurities are thus removed by oxidation. |
| Bismuth | (english) Chemical symbol Bi. A soft, course cystalline heavy metal with a silvery white color and pinkish tinge; usually produced as a by-product of copper,leaad and other metals. Has a thermal conductivity lower than all other metals except mercury. Used as alloying agent but leading use is in pharmaceuticals. |
| Blue Print | (english) A pen or ink line drawing reproduced (printed) on sensitized paper by direct exposure. |
| Bridle | (english) A set of rolls used to maintain tension on the strip as it goes through the line. |
