Rolling metal at a temperature below the softening point of the metal to create strain hardening (work hardening). Same as cold reduction, except that the working method is limited to rolling. Cold rolling changes the mechanical properties of strip and produces certain useful combinations of hardnes...

In addition, after deriving the final formula, he conducted a number of mathematical studies on the continuity of its derivatives (using Abel transformations). It is worth mentioning that Szymański in his work [13] analyzed, similarly to Gromeka, the pulsating nature of the flow, and this ...
Rubber compounds used in the back covers of pipe belts are highly dependent on the temperature and loading frequency [33,36], and an increase in the temperature reduces the indentation rolling resistance of the belt, thereby reducing its contact forces and favoring belt rotation. Exposure to ...
