By-Pass

Bi-Coil

(english) Also BY-COIL. Tin Mill term. Customers buy "by coil" or "bi-coil" rather than cut sheets

Hydrologic Cycle

(Concrete Engineering) The Hydrologic Cycle consists of the evaporation of water from oceans and other bodies of open water; condensation to produce cloud formations; precipitation of rain, snow, sleet or hail upon land surfaces; dissipation of rain or melted solids by direct run-off into lakes and by seepage into the soil. Thereby producing a continuing endless source of water in the sub-grade.

Nitrogen fixation

(Environmental Engineering) The conversion of atmospheric (or dissolved) nitrogen gas into nitrate by microorganisms.

Z-Mill

(english) The full name for z-mill is Sendzimir mill. A Z-mill operates with a very small diameter work roll, normally about 2 inches, backed up by a number of rolls in a pyramid-shaped stack. This roll set up allows you to exert extremely high forces through the work roll and yet keep the work roll from extreme flexing. The take-up roll on the Z-Mill also exerts a tension on the coil as it comes through the mill. The combination of high pressure and tension makes the mill capable of rolling material thin and flat.

Bottle Top Mold

(english) Ingot mold, with the top constricted; used in the manufacture of capped steel, the metal in the constriction being covered with a cap fitting into the bottle-neck, which stops rimming action by trapping escaping gases.

Bloom 2

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).

Brinell Hardness Test

(english) A common standard method of measuring the hardness of materials. The smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure. The diameter of the indentation, in the material surface, is then measured by a microscope and the hardness value is read from a chart or determined by a prescribed formula.

By Coil

(english) Selling term which refers to product sold in the form of a coil vs. cut plate. "Bi Coil" is also used in production to refer to coils vs. cut plate
