Rolling is the most commonly used and the most efficient type of metal forming, which consists in deformation of metal by means of rotating rolls (Fig. 1.1, a , b , c ); 75-80% of the total
Get PriceThe rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc.
Get Price3 5 A machine used for rolling metal is called rolling mill. A typical rolling mill consists of a pair of rolls driven by an electric motor transmitting a torque through a gear and pair of cardans. The rolls are equipped with bearings and mounted in a stand with a screw
Get PriceIt has long been recognized that some, if not most, of the variations in thickness of strip produced by a cold-reduction mill have their origin in the hot rolling process. For example, it has been shown that in many coils of metal produced by a cold mill several heavy areas can be identified which result from water-cooled skids in the slab-heating furnace preceding the hot-strip mill.
Get PriceHot rolled products are made by a hot rolling process. In that process, the process is done at a very high temperature like over 1,700 Degree Fahrenheit. For most of the metals, this temperature is re-crystallization temperature.
Get PriceHot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519. When most people think of a rolling

Get PriceSuranaree University of Technology Jan-Mar 2007 Fundamental concept of metal rolling 1) The arc of contact between the rolls and the metal is a part of a circle. 2) The coefficient of friction , µµµµ, is constant in theory, but in reality µµµµvaries along the arc of
Get Price3.1 Key Feature of Process Control: Detection of Periodic Defects Rolls and rollers are the most heavily used parts of a rolling mill. Due to wear from contacting hot material with great force, their lifetime is limited. Although rolls are refurbished in the roll shop
