In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.
reversible, rolling in an intermediate mill and in a finishing mill, possible followed by some kind of heat treatment. For steel qualities that can be deformed at higher speeds without problems, some of the last passes can be performed in a wire block. The difference between shape rolling and hot strip rolling is that instead of flat rolls, the ...

Rolling mill guide equipments play a major role in ensuring the surface quality of the rolled product. The guides are to be designed for the wide variety of stock sizes and shapes which are normally encountered in the long product rolling. In modern long product rolling mills roller guides are normally used both for entry and exit guides.
possible reason why the optimum friction range exists. 2. Mathematical Models 2.1. Continuous Rolling Model In order to simulate vibration behaviour of a five-stand rolling mill, continuous rolling is modelled, as schematical-ly represented in Fig. 1. The roll gap model provides the rolling force response and the material velocity.
