The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls. Read More
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. This reduction in work roll diameter Reduces overall separating force required for reductions

May 02, 2017 Planetary Rolling Mill In this type of rolling machine, a large backup roller is surrounded by various numbers of planetary working rollers as shown in figure. Each planetary roll gives constant reduction. It is used to reduce large thickness in single pass of steel strip. Its rolling capacity is more than cluster machine but less than tandem ...
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 coldrolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot and cold ...

This also means a significant reduction of CO2 emissions. With a length of just 180 meters, the plants also have considerably more compact dimensions than conventional casting and rolling mills. A wide range of high-quality and ultra-thin steel grades can be produced with the endless cast-rolling process.
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.
This machine uses hot rolling process for making the required product. The Steel Rolling Machine is run by the giant 1000HP motor. Motor runs at 737 rpm. The motor is connected to the flywheel with the help of belt drive. The flywheel is further connected to reduction gearbox. The reduction gearbox reduces the speed up to 112 rpm.
