Section Rolling Mill. Rolling mills are facilities that carry out a series of processes including rolling the billets, blooms, slab and beam blanks – extracted from the reheating furnace – into the prescribed size and correcting any bending, cutting them into given lengths, then piling or bundling as needed for shipment.
Developments in mixing mill. Stock Blender: A main disadvantage in mixing on a two-roll mill is that the process is dependent on the operator skill. Stock blenders reduce this operator variable in the mixing process. Use of a stock blender improves mixing quality, reduces human interference and gives consistent productivity.

At today's demanding condition, maintaining stable operation of rolling mill is becoming difficult. MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the opposite side with constant force. MSD eliminates gap between roll chocks and mill housing, keep rolls in proper position and stabilize rolls.

The Ferrari Sugar Milltandem in Brazil is fully automated with variable speed for all the drives involved. The mills' rollers are individually moved by electro-hydraulic drives (including the fourth roller in millone), thus offering a great advantage to automate the millin a very accurate way and to also measure the speed and torque in each of the rollers driven.
So, for limited diameter change torque mode center winders, this control method can give fairly constant tension and then taper tension beyond the 2.5:1 range. This is suitable for many limited range winder applications. Motor maximum speed is …

A Hägglunds hydraulic direct drive is a drive system beyond the ordinary. In far less space than other drives— and with far less weight and complexity—it delivers flexible, reliable power. With a Hägglunds drive, your machine has unlimited access to high torque. Yet it's also protected from torque stresses.
2. Three-High Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction.
All hydraulic applications are based on flow and pressure requirements. Flow, expressed in gallons per minute (GPM), determines the speed at which a hydraulic cylinder extends or a hydraulic motor turns. Flow is produced by the pump. Pressure, expressed in pounds per square inch (PSI), determines the amount of force exerted.
