Rolling mill arrangements commonly used in manufacturing industry today include the two high mill, the two high reversing mill, the three high mill, the four high mill, the cluster mill, and the tandem rolling mill.
Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used.
The rolling mill is operated with a hand crank, a reduction gear making the work as easy as possible. The gap between the sheet rolls is adjusted with the large wheel mounted on the top of the machine; the wire rolls are regulated with two knurled knobs out of sight beneath.
Cold Rolling of Steels The primary purpose of cold rolling of steels is to reduce the thickness of the hot rolled steel strips (normally in the range of 1.5 mm to 5 mm) into thinner thicknesses (usually in the range of 0.12 mm to 2.5 mm) which cannot be normally achieved during hot rolling in a hot strip mill.
