Equal speed asymmetric rolling
WebFeb 15, 2024 · Secondly, an outline of various rolling techniques like thread rolling, incremental rolling, shape rolling, and some other advanced techniques like corrugated rolling, riblet rolling, and symmetric and asymmetric rolling, are discussed in detail with their merits, demerits, and applications. WebAsymmetric rolling due to purposefully created differences in the circumferential speeds of the work rolls is also called “differential speed rolling”. For such a process, a degree of asymmetry is defined by a ratio of circumferential speeds and of the work rolls according to Equation (1): (1) where is the “speed ratio” and .
