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

working principle of two roll mixing mill

A three roll mill or triple roll mill is a machine that uses shear force created by three horizontally relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it. Operation of a three roll mill[edit] nip experiences very high shear force due to the different rotation speeds of the two rolls.

Welded roll forming system versus tube mills: What’s the

In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds (see Figure 1). Diameter range is mentioned because a tube mill welds a round product.
