The invention of the rolling mill in Europe may be attributed to Leonardo da Vinci in his drawings. The earliest rolling mills in crude form but the same basic principles were found in Middle East and South Asia as early as 600 BCE. Earliest rolling mills were slitting mills, which were introduced from what is now Belgium to England in 1590. Get price

Arms Production

The iron masters used rolling mills to supply manufacturers with bars and rods of the sizes they required. One of Whitney, Sr.'s earliest orders to Forbes and Adam, suppliers of rolled iron in the Salisbury district of northwest Connecticut, specified bars of widths 1 5/8, 2 1/2, and 4 1/4 inches, totalling 1000 pounds of Salisbury best bloomed iron.

Hot Rolled vs. Cold Rolled Steel

The process of hot rolling involves rolling steel at a temperature above the steel's recrystallization temperature, which takes place over 1700 degrees Fahrenheit. Steel that is above the recrystallization temperature can be shaped and formed much more easily than colder steel, and the steel can start in much larger sizes. Get price

Puddling (metallurgy)

Puddling is a step in the manufacture of high-grade iron in a crucible or furnace. It was invented in Great Britain during the Industrial Revolution. The molten pig iron was stirred in a reverberatory furnace, in a oxidizing environment, resulting in wrought iron. It was one of the most important processes of making the first appreciable Get price

The History of Steel

2020/8/21The low investment cost involved in setting up EAF mills allowed them to compete with the major US producers like US Steel Corp. and Bethlehem Steel, especially in carbon steels, or long products.

Hot Cold Working and the Rolling Process

To improve on the yield and productivity, the method of continuous rolling of several slabs, i.e. endless rolling, is being adopted. This process consists of three reheating furnaces, a sizing press that reduces the slab width, three roughing mills, a coil box, a joining device (sheet bar welder), a 7-stand finishing mill, a strip shear and two down coilers.
