In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.
be applied on therolls in the best manner. In many cases roll cooling goes along with lubrication. The characteristics of the various coolants used for roll cooling are explained with regard to cooling and lubricating effects. Depending of the type of rolling mill, dedicated roll cooling systems are required to fulfill the required functions.
The mill maintenance personnel and roll shop operators can also work together to regularly inspect the chocks and seals. Chocks are the mechanical housing that holds the bearings in place and allows for sealing at the end of each roll (where lubricant comes in and most water washes out).
LUBRICATION OF HOT-STRIP-MILL ROLLS 205 To avoid problems with front-end entry the oil was switched on by a signal from the main-drive motor load and switched off before the tail end had passed through the mill by similar means. In this way time was allowed for the oil to "burn on" the rolls before the next slab was ready for processing.
Lubrication in an integrated steel plant is a major challenge with numerous types of lubricants and various types of equipment. The steel plant equipment work under various operating parameters; like from extreme heavy load to very high speed, low temperatures to high temperatures, dusty polluted environment to humid acid environment.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
To integrate a new roll gap lubrication system into an existing hot strip mill is a challenge problem. A lubrication expert system was developed and embedded into finish rolling setup system. The reference value setup by expert system is downloaded to roll bite lubrication PLC via finish mill PLC to open oil spraying valve and regulate the oil
Concepts Achenbach offers the following types of hot rolling mills: Single-stand reversing hot rolling mills for smaller strip production volumes and two- and four-high sheet production; Hot rolling lines with single-stand reversing roughing mills and finishing mills for medium production volumes in two- and four-high design; Hot rolling lines with single-stand reversing roughing mills and
The majority of cold and foil rolling operations use oil-based lubricants, although some mill systems can accommodate water-based alternatives. The base oil represents more than 90% of the total lubricant volume and acts as a solvent for the load bearing additives and a roll-cooling medium.
thickness tolerances and surface quality. Effective lubrication systems are crucial for achieving these goals. For that reason, the effect and the characteristics of the lubricating material toward product surface and friction is of great importance. In hot rolling, roll wear including the rolled surface

Aug 20, 2002· Hot roll lubrication has been known about for a long time and the latest research has demonstrated the advantage and value of this method to mill owners and their customers. The key lies in the commitment and professional approach by all concerned parties to make this method work.
Dec 19, 2013· Diagnosis: Judging by your description of the gearbox to the touch of a hand, I estimate its temperature to be around 150 F (or 65 C)—the approximate temperature when the hand has to be lifted within three seconds of touch. That’s too hot, especially since the normal “warm to the touch” temperature would be approximately 104 F (or 40 C).. An oil-temperature rise reacts according to the
