The squeezer was like a table where one half of the surface folds over on top of the other and a press flattens the doubled over plate so the rolled end will fit in the rollers. It is then reheated for another set of rolling. This is repeated until the desired geometry is reached.
The mill was originally an ironworks, but Revere used a loan from the Department of the Navy to convert it into a copper foundry, completing America's first copper rolling mill. The most important pieces of equipment were the rollers themselves, which consisted of large iron cylinders through which raw copper would be inserted and compressed.
Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property.
In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2).

This was then rolled until it had doubled in length. The plate was then folded in half ('doubled') using a doubling shear, which was like a table where one half of the surface folds over on top of the other. It is then put into a furnace to be heated until it is well 'soaked'. This is repeated until there is a pack of 8 or 16 plates.

The first ever cast iron rails are laid at Coalbrookdale. [2] [3] [4] Kambarka Engineering Works, now recognised for its rolling stock and locomotives, opens in current-day Urmdurt, Russia. Plans are drawn up for the construction of a canal between Witton Park and Stockton-on-Tees which instead becomes the route of the Stockton and Darlington ...
