of the metal before rolling and a wipe down with a shot of WD-40 after use and a wipe down with a clean cloth or a bit of alcohol before use. There is no need for oil on the rolls in use, none of the hand mills or even the studio power mills need lubrication on the rolls because we don't work the metal hard enough in a single pass to require it.
Further areas of use of central lubrication plants are e.g. tool and textile machines, conveyor belts and industrial plants such as sawmills and rolling mills. Central oil lubrications are used e.g. in commercial vehicles such as construction machines, combine harvesters and tractors. Step-by-step integration of central lubrication technology

The 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. Rollers may be plain or grooved depends upon the shape of rolled product.
In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold ...
