Roll Bonding of Steel Net-Reinforced Aluminium Strips

The present study is dedicated to the experimental determination of strain parameters at rolling of aluminium matrix with inserted wire netting. Two types of stainless steel fabric netting with different orientation to the rolling axis were placed between two aluminium strips and hot rolled. The rolling temperature and reduction were varied to achieve the sound bonding between the matrix ...

Rolling (metalworking) - Wikipedia

Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.

Cold pilger mills | SMS group

Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in, and rotated by, a thrust block. Two dies (3) "form" the tubular stock in the same way that a rolling pin rolls out pastry.
