Calenders an overview ScienceDirect Topics

The first step of a calendering process is to melt and uniformly mix the material. This is achieved in the plasticating unit where the material is melted and mixed by an internal batch mixer or a roll-mill. The paste-like mass is then fed between the nips of the first two rolls; the first pair of rolls controls the feeding rate, while subsequent rolls in the calender calibrate the sheet thickness. As the material moves between several calender

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS

After a roll change or a mill stop rolls need some time to return to stable thermal conditions, every new bar entering the mill creates an impact, and sometimes there are really severe rolling accidents, due to faults by operators, weak rolled materials with internal defects, or because of other problems in a mill such as a power cut, mechanical problems of transportation or in the water
