Shear strain:

(english) Strain measuring the intensity of racking in the material. Shear strain is measured as the change in angle of the corners of a small square of material.

Actual Weight

(english) The customer buys by the actual (scale) weight of the steel. The theoretical weight is used in estimating, however, it is not to be used for billing.

Boring Tool

(english) A cutting tool in which the tool bit,the boring bar and in some cases the tool holder are incorporated.

Architecture

(Software Engineering) the overall structure of software components, the data and/or content that components manipulate, and the relationships between them

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.

Nitrification

(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.

Phototroph

(Environmental Engineering) Organisms which obtain energy from light using photooxidation.

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.

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.

B Elevation

(english) The bottom level of the boiler firebox where two oil guns are located. The oil guns are used if the boiler needs extra steam while on oil fire.

Bent Axis Pumps

(english) In this pump, the pistons are at an angle to the drive shaft and Thrust Plate. The piston block shaft is connected to the drive shaft by a universal joint, not shown. The drive shaft, thrust plate, piston block shaft, and piston block all revolve. The connecting rods are attached to the thrust plate and revolve with it, unlike the swash plate pump where the piston rods slide past a stationary swash plate. The outlet ports are semi-circular holes in the Valve Plate, shown on the far right of the animation on edge and in a head-on view below, right. As the pump revolves, half the pistons suck in fluid as they pass over the intake port. The other pistons discharge their fluid through the outlet port. This pump should be compared to the radial piston pump, swash plate pump, and wobble pump.

Elementary reaction

(Environmental Engineering) A reaction in which the rate expression corresponds to the stoichiometric equation.
