In this article, relationships among metallurgy, heat transfer, and control of the cooling system in steel rolling are first discussed. Heat transfer characteristics associated with the water spray and jet cooling used in rolling processes are then studied.
In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oC depending on product.
spray headers that blast the intensely hot slab with 1,500 psi pressurized water to remove the 1/8inch thick layer of oxidized iron that forms at the surface of the slab in the oxygenrich atmosphere of the reheat furnace. Shortly after descaling, a (relatively) small 2hi rolling mill called a scalebreaker reduces the slab's thickness by

The discs of an attrition mill are generally in a vertical position so that materials not capable of reduction can pass by gravity out of the grinding area. Roller Mills. A combination of cutting, attrition, and crushing occurs in roller mills.
Drum Drying also known as Roll Drying is a continuous process that creates dry powders and flakes from a liquid feedstock. The liquid feed is sprayed onto or in between two rotating drums. The drums are heated internally with steam to increase the surface temperature. As the material is sprayed onto the drums, it sticks and dries to the surface.
Roller mills are commonly referred to by the type of service they perform. A mill used to crack grain or other types of friable materials may be called a cracking mill. Mills used to flake grains or other products may be called flaking mills or flakers. Roller mills used to grind in a feed mill are commonly referred to as a roller mill or ...

The rolling process is shown in Fig. : 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. Rollers may be plain or grooved depends upon the shape of rolled product.
