Chemical oxygen demand (COD)

(Environmental Engineering) The amount of oxygen required to oxidize any organic matter in the water using harsh chemical conditions.

Banding

(english) Inhomogeneous distribution of alloying elements or phases aligned in filaments or plates parallel to the direction of working.

Burnt Rubber

(english) Small or large black spots that generally show up on surface and are generally caused by pickling steel too hot.

Acetyl Tributyl Citrate

(english) One of the lubricating oils generally applied on tin Mill Products (tin plate, TFS-chrome/chrome oxide coated steel, and blackplate).

Biochemical oxygen demand (BOD)

(Environmental Engineering) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.

Boron Steels

(english) The addition of boron in the range 0.0005-0.005% to certain steels increases the hardenability. A range of boron steels is now listed in the current BS 970 and are widely used for the production of cold headed fastenings.

Chlorofluorocarbons

(Environmental Engineering) Synthetic organic compounds used for refrigerants, aerosol propellants (prohibited in the U.S.), and blowing agents in plastic foams. CFCs migrate to the upper atmosphere destroying ozone and increasing global warming. Typical atmospheric residence times are 50 to 200 years.

Backoff

Removal of part of coil from entry end of unit; may be necessitated by a defect in coil or by a wreck in the mill, etc. Backoff weight is the part of the coil that is removed and not finished/produced.

Brown Sharp Gages

(english) A standard series of sizes refered to by numbers, in which the diameter of wire or thickness of sheet metal is generally produced and which is used in the manufacture of brass, bronze, copper, copper-base alloys and aluminum. These gage numbers have a definite relationship to each other. In this system, the decimal thickness is reduced by 50% every six gage numbers- while temper is expressed by the number of B&S gage numbers as cold reduced in thickness from previous annealing. For each B&S gage number in thickness reduction, where is assigned a hardness value of 1/4 hard.

BREATHER

(english) A device which permits air to move in and out of a container or component to maintain atmospheric pressure.

Boiler

(english) A closed vessel in which water, is transformed into steam at a given pressure and temperature under controlled conditions.

Trickling filter

(Environmental Engineering) An attached growth biological process in which the microbial film is attached to non-moving rock or plastic media.
