| Balanced Steel | (english) Steels in which the deoxidisation is controlled to produce an intermediate structure between a rimmed and killed steel, Sometimes referred to as semi-killed steels, they possess uniform properties throughout the ingot and amongst their applications are boiler plate and structural sections. |
| Baller Stick | (english) Octagon-shaped wooden stick approximately 5' long. This stick is used in the baller area, to change burr mashers, to start a coil with a large ID, etc. |
| Balling Drum | (english) A rotating drum that is used for adding moisture to the sinter mix in the Blast Furnace. Also, it enhances a balling action where the smaller sized materials adhere to larger materials. |
| Bamboo Grain Structure | (english) A structure in wire or sheet in which the boundaries of the grains tend to be aligned normal to the long axis and to extend completely through the thickness. |
| Band Saw Steel (Wood) | (english) A hardened tempered bright polished high carbon cold rolled spring steel strip produced especially for use in the manufacture of band saws for sawing wood, non ferrous metals, and plastics. Usually carries some nickel and with a Rockwell value of approximately C40/45. |
| Bars | (english) A relatively long straight, rigid piece pf metal; long steel products rolled from billets into such shapes as squares,rectangles, rounds,angles,channels,hexagons,and tees. In steel, “merchant bars” include rounds,flats,angles,squares,and channels that are used by fabricators to manufacture a wide variety of products such as furniture,stair railings and farm equipment. Concrete reinforcing bar (rebar) is used to strengthen concrete in highways,bridges and buildings. |
| Base Box | (english) Unit of area of 112 sheets of tin mil products (tin plate, tin free steel or black plate) 14 by 20 inches, or 31,360 square inches. Tin Plate is sold, and carried in finished inventory, on a weight per unit area rather than on a thickness basis. |
| Base Type | (english) Tin Mill term; Thickness divided by .00011. Also weight in pounds of one Base Box of Tin plate. In finished inventory base weight is specified instead of decimal thickness. |
| Basic Oxygen Furnace (BOF) | (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. " |
| Basic Oxygen Process | (english) (BOP) A process in which molten steel is produced in a furnace by blowing oxygen into molten iron, scrap and flux materials. The furnace is known as Basic Oxygen Furnace (BOF). |
