Finally a pair of high-pressure headers operating at nearly 3 000 psi makes a final pass at both surfaces of the transfer bar shortly be fore it enters F6 for finish rolling. As with the roughing mill s descaling system for some thinner-gauge wider and/or stiffer products the low-pressure header is disabled to conserve heat for rolling.

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.

The calculation of rolling forceInnoval Technology
The calculation of rolling force. When manufacturing sheet products it s important to understand the rolling force. This is because you need it to set the appropriate roll gap on the mill accounting for the stretch of the stand. The prediction of rolling force can be challenging due to the large number of inter-connected process variables
