Flattening definition of Flattening in the Free Online Encyclopedia.

flattening [′flat·ən·iŋ]

(geodesy)

The ratio of the difference between the equatorial and polar radii of the earth; the flattening of the earth is the ellipticity of the spheroid; the magnitude of the flattening is sometimes expressed as the numerical value of the reciprocal of the flattening. Also known as compression.

(metallurgy)

Straightening of metal sheet by passing it through special rollers which flatten it without changing its thickness. Also known as roll flattening.

Flattening

a means of producing thin metal strip, with a width-to-thickness ratio not exceeding 15, mainly by cold rolling gauged round wire in smooth rollers. Multistand continuous rolling mills and single-stand two-roller and multiple-roller mills with rollers 5–250 mm in diameter, made from very hard steels, are used for the flattening of metals. On a smaller industrial scale, ultrasonic forging devices are also used.

The main advantage of flattened strip (thickness, 0.005–1 mm; width, 0.05–15 mm) over strip produced by longitudinal cutting of cold-rolled bands is the roundness of the edges, which significantly improves the performance characteristics of items. In addition, in flattened strip the dimesional precision is higher and the surface quality is better. Such strip is used in manufacturing precision springs (including watch springs), electrical resistors, elastic elements of high-frequency oscillographic galvanometers, and special sewing needles.
