Wire and Rod Drawing Process for Steel – IspatGuru
Wire and Rod Drawing Process for Steel. Drawing of wire from steel rod is a metal working process used for the reduction of the cross-section of the rod. Similarly rods are drawn from steel rounds of larger diameters. During drawing the volume remains the same and hence there is increased in the length of the drawn wire or rod.

Tube drawing principles - The Fabricator
Five tube drawing methods are sinking, rod drawing, floating plug drawing, tethered plug drawing, and fixed plug drawing. Choosing the right method or combination of methods for a particular application requires understanding the characteristics of each. Tube producers also have a choice of feedstock: seamless or welded tube. Likewise, choosing the right one is a matter of …

Evolution of artificial defects during shape rolling
In this respect the final step in wire rod rolling is the main focus since the largest deformation rates appear there resulting in the most severe deformation conditions. The aim of this thesis is to investigate the evolution of defects using 3D FE simulations of wire rod rolling in a wire rod block using a FE program MSC.Marc.
steel - Billets, bars, and rods | Britannica
Rods. Rod mills are similar to bar mills at the front end, but the finishing end is different. Rods have a smaller section (5.5 to 15 millimetres in diameter) and are always coiled, while bars are normally shipped in cut length. The final rolling in rod mills often takes place in a close-coupled set of 10 pairs of small rolls (200 and 150 ...

Analytical Engine. It seems a real miracle, that the first digital computer in the world, which embodied in its mechanical and logical details just about every major principle of the modern digital computer, was designed as early as in 1830s. This was done by the great Charles Babbage, and the name of the machine is Analytical Engine.

Rolling (metalworking) - Wikipedia
The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for re-rolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and hexagons.
