A rolling mill is a machine or factory for shaping metal by passing it between rollers. This article is about devices that perform tasks. ... A factory worker in 1940s Fort Worth, Texas. ... Hot metal work from a blacksmith In chemistry, a metal (Greek: Metallon) is an element that readily forms positive ions (cations) and has metallic bonds. ... Roller may mean: In biology: Roller, family of brightly coloured near passerine birds in the genera Coracias and Eurystomus In industry: Roller (machine part), a cylindrical machine component or a component of a roller bearing Roller (agricultural tool), an agricultural or gardening implement for levelling ground Road roller (also called...

Rolling mills are often incorporated into integrated steelworks, but also exist as separate plants and can be used for other metals, and other materials. A steel mill (British English and Australian English steelworks) is an industrial plant for the manufacture of steel. ... Hot metal work from a blacksmith In chemistry, a metal (Greek: Metallon) is an element that readily forms positive ions (cations) and has metallic bonds. ...

Rolling mills historically have been of several kinds:

A slitting mill was used to cut flat bar iron into rods for nail-making.
A tinplate works normally contained at least two rolling mills, one for hot rolling and the other for cold rolling single plates, prior to tinning.
From the Industrial Revolution, puddled iron, after consolidation with a powered hammer (shingling), was rolled into bar iron using a rolling mill with grooved rolls. The grooves provided were progressively smaller, so that on successive passes through the rolls, the cross-section of the bar became smaller and the bar itself longer. By designing the rolls appropriately, it is possible to obtain iron or steel with various cross-sections, including I-shaped girders and railway rails.

The Slitting Mill was a water-powered mill for slitting bars of iron into rods. ... A wrought iron railing in Troy, New York. ... A pile of nails. ... Plating is the general name of surface-covering techniques in which a metal is coated onto a solid surface. ... Hot rolling is a metallurgical process in which the metal is passed through a pair of rolls and the temperature of the metal is above its recrystallization temperature, as opposed to cold rolling, which takes place below it. ... Rolling mill for cold rolling metal sheet like this piece of brass sheet. ... A Watt steam engine in Madrid. ... Schematic drawing of a puddling furnace The puddling furnace is a metalmaking technology to create wrought iron from the pig iron produced in a blast furnace. ... General Name, Symbol, Number iron, Fe, 26 Chemical series transition metals Group, Period, Block 8, 4, d Appearance lustrous metallic with a grayish tinge Atomic mass 55. ... Shingling was a stage in the production of bar iron or steel, in the finery and puddling processes. ... A wrought iron railing in Troy, New York. ...

Rolling Mill Machinery Rolling Mills Tools : Machinery International Corporation (357 words)
	The selection of the proper rolling mill for an application is essential to the success of any project and Machinery International's experience in this industry has aided customers in determining the proper rolling requirements for an application and the subsequent matching of the most appropriate used mill allowing for that success.
	In addition, mills are available as single stand or tandem lines, work roll driven or back up roll driven and with manual, electromechanical or hydraulic screwdowns.
	As important as the rolling mills are, without the use of the proper ancillary and support equipment the rolling project would not be successful.

Rolling mill - Patent 4614099 (5668 words)
	The rolling mill of claim 11 wherein the control means is further operable to compensate for differences between the diameters of the upper and lower reducing rolls by causing a proportionally slower rotation of the larger reducing roll to effect equal surface speeds of the upper and lower reducing rolls.
	Larger capacity rolling mills are also required to achieve deeper penetration of the metallurgical structure of a workpiece during the rolling and for decreasing the number of passes required to effect a given reduction in thickness or other change of shape of a workpiece during form rolling.
	The rolling mill of the present invention is particularly suited for specialized rolling, such as that of special armor plate, to provide improved surface characteristics by increasing the depth of penetration of the workpiece and by reducing stretching to maintain the crystal structure at the surface of the workpiece.
