The typical rolling mill is a "4high mill" which means that there are four rolls. From the top they are (1) top backup roll, (2) top work roll, (3) bottom work roll, (4) bottom backup roll. On the cold mill where I worked many years ago, the work rolls were about 11 inches in diameter while the backup rolls were about 60 inches in diameter. This was on a mill with a width of 120 inches (10

· What is Joule''s Law of Heating. The heat which is produced due to the flow of current within an electric wire, is expressed in unit of Joules. Now the mathematical representation and explanation of Joule''s law is given in the following manner.. The amount of heat produced in a current conducting wire, is proportional to the square of the amount of current that is flowing through the wire

The mill rolls are hollow to allow flow of coolant (most commonly water) for control of roll and stock temperatures. A number of safety features are incorporated into mill design, including shutoff switches and brakes to stop the rolls quickly, means to move the rolls apart, and guards to keep hands and tools away from the nip area. Stringent operator training and adherence to safe procedures

Mills are designed in different types of configurations, with the most basic being a twohigh nonreversing, which means there are two rolls that only turn in one direction. The twohigh reversing mill has rolls that can rotate in both directions, but the disadvantage is that the rolls must be stopped, reversed, and then brought back up to rolling speed between each pass.
