Rolling Mill History Steel Machinery American Steel

Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and builttoorder to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills.

Metal Rolling Manufacturing

Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing
