| Back Rake | (english) The angular surface ground back from the cutting edge of cutting tools. On lathe cutting tools. The rake is positive if the face slopws down from the cutting edge toward the shank, and negative if the face sloopes upward toward the shank. |
| Bander | (english) Machine located at each delivery reel to automatically place circumference bands around completed coils. |
| Banding Tool | (english) Tool used to tighten a steel band around a coil. |
| 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. |
| Bead | (english) 1)Half-round cavity in a mold, or half-round projection or molding on a casting, 2) a single deposit of weld metal produced by fusion. |
| Bedding | (english) Sinking a pattern down into the sand to the desired position and ramming the sand around it. |
| 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. |
| Billet | (english) (1) A semi-finished section hot rolled from a metal ingot, with a rectangular cross section usually ranging from 16 to 36 in., the width being less than twice the thickness. Where the cross section exceeds 36 in., the term “bloom” is properly but not universally used. Sizes smaller than 16 in. are usually termed “bars”; a solid semi-finished round or square product which has been hot worked by forging, rolling, or extrusion. (2) A semi-finished, cogged, hot rolled or continuous-cast metal product of uniform section, usually rectangular with radiused corners. Billets are relatively larger than bars. |
| Billet 2 | (english) A solid semi-finished round or square product that has been hot worked by forging, rolling, or extrusion. An iron or steel billet has a minimum width or thickness of 1 1/2 in. and the cross-sectional area varies from 2 1/4 to 36 sq. in. For nonferrous metals, it may also be a casting suitable for finished or semi-finished rolling or for extrusion. |
| Bright Basic Wire | (english) Bright steel wire, slightly softer than Bright Bessemer Wire. Used for round head wood screws, bolts and rivets, electric welded chain, etc. |
