(english) Submerged roll in the pot used to keep the strip submerged in the pot.
(english) The energy stored in a raised object (e.g. the weights in a grandfather clock). Potential energy equals mgh, where m is mass, g is the acceleration of gravity, and h is the vertical distance from a reference location. It is called potential energy because the energy can be regained when the object is lowered. This type of potential energy is sometimes called gravitational potential energy in order to distinguish it from elastic potential energy: see elastic energy.
(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.
(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.
(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.
(Concrete Engineering) Development of relatively small cavities in a concrete surface, due to phenomena such as cavitation or corrosion.
(english) The process of annealing in a protective atmosphere so as to prevent discoloration of the bright surface desired.
(Software Engineering) the ability of software to operate in a manner that is secure from internal or external attack
(Concrete Engineering) A property of a solid that indicates its ability to withstand bending.
(Software Engineering) a collection of program components (modules) that is tested as a group
(english) In two dimensions, a fixed connection between two members restrains all three degrees of freedom of the connected member with respect to one another. A fixed connection is sometimes called a rigid connection or moment-resisting connection.
(Concrete Engineering) Moisture which is mechanically held in a material. In aggregates, that water which is not available to become part of the mixing water is designated "absorbed" water.
